Abstract

Description

RHEOLOGY MODIFIED COMPOSITIONS AND PROCESSES THEREOF

The present invention is directed to rheology modified compositions, and to methods for forming the compositions. The compositions and methods are useful in applications including cosmetics, pharmaceuticals, and household products.

BACKGROUND OF THE INVENTION

For many applications, including personal care, pharmaceuticals, and household products, it is desirable that compositions for use in the intended applications have a desired viscosity. In particular, a number of applications require that the compositions used therefor have a relatively high viscosity. The rheology can affect properties such as, for example, ease of application, ease of handling, esthetic appeal, product stability and retention of a product where applied.

Personal care formulations such as lotions and creams can contain large amounts of solvent. Such formulations often use an oil or emollient as a solvent or a primary component. While oils possess highly desirable properties for cosmetic use, such as emolliency and the ability to solvate and remove make-up, the presence of oils can be inconvenient in the fluid form and present difficulties in application. Household products such as cleaning products can contain substantial amounts of oil or wax as solvents or major components. It is generally desirable that a cleaning product applied to a surface, particularly a hard surface, not run over the surface before it can be wiped. Products such as furniture polish are often oil or wax-based, and should be thick enough to remain where applied so that polishing can be accomplished.

Some of the undesirable properties of oils or emollients can be decreased or eliminated by rheological modification such as thickening of the oil. For example, a cosmetic formulation can be used in a thickened composition, such as a cream, gel, or a water-in-oil or oil-in-water emulsion, particularly a water-in-oil emulsion. Preparation of water-in-oil emulsions generally requires thickening of the continuous oily phase of the emulsion. Thickening of the oily phase can also be required in preparing cosmetic gels, particularly anhydrous gels.

The presentation of a formulation in the form of an anhydrous gel is useful, for example, if components of the formulation are sensitive to moisture and/or to oxygen. Certain ingredients in cosmetic or pharmaceutical formulations are unstable in water. For example, vitamin C degrades in water relatively rapidly. Thus, such unstable ingredients are advantageously provided in anhydrous formulations such as an anhydrous gel. Oily compositions, such as oily dispersions, are suitable anhydrous formulations; however, in addition to other difficulties associated with oily compositions as discussed herein, such unstable ingredients can be insoluble or insufficiently soluble in oily formulations.

Polymers are known for use as thickeners or rheology modifiers in personal care, household and pharmaceutical applications. However, certain polymers can be incompatible with other components in the formulations, such as fragrances in cosmetic formulations. Thickening of oils can also be accomplished by incorporation of silicas, bentonites or metal salts of fatty acids such as aluminum salts, or esterified derivatives of sugars such as dextrin palmitate. Thickening has also been accomplished by incorporation of a wax in the oily phase. However, creams thickened by simply adding waxes, silicas or bentonites can have a texture that is unappealing or difficult to use.

U.S. Patent No. 5,318,995 discloses a method for thickening a water-in-oil emulsion by using copolymers containing a slight amount of ionic or ionizable groups. European Patent No. EP 550,745 discloses thickening of the oil phase of a cosmetic composition using a combination of two copolymers.

The use of polysaccharide alkyl ethers for thickening oil-based compositions is described in European Patent Application No. 795,322. However, the disclosure provides that the process is generally applicable to certain oils having solubility parameters within a specified range.

Thus, a need continues for methods and compositions useful in thickening solvent-based formulations for personal care, pharmaceutical, and household uses. There is also a need for compositions that have the advantageous properties of oils but with minimization or elimination of undesirable properties. The present invention is directed to these, as well as other, important ends.

DETAILED DESCRIPTION OF THE INVENTION

The present invention provides improved oil-containing compositions for personal care, pharmaceutical, or household applications, and methods for making the compositions. It has been surprisingly and unexpectedly found that the use in such compositions of a rheology modifier and a hydrogen-bonding compound can provide compositions having desired properties, such as viscosity, for use in the intended applications, while reducing undesirable properties often observed in oil- containing compositions. It has further been unexpectedly found that the compositions and methods of the present invention can be used to provide improved optical clarity, as evidenced by measurable decreases in turbidity, of compositions containing organic solvents and polymers. A further unexpected property of the methods and compositions of the present invention is that they can provide improved properties, such as increased viscosity and improved optical clarity, when used at room temperature. That is, although heating may be advantageously used for example, to speed mixing of components of the compositions of the present invention, it has been unexpectedly discovered that heating is not necessary to effect uniformity and/or clarity of the compositions. Thus, the compositions of the present invention can be prepared at ambient temperature. The methods and compositions of the present invention can be used, if desired, to provide personal care, pharmaceutical, or household compositions that are solid at room temperature. The use of the compositions and methods of the present invention in formulating solid compositions can provide for reduction of constraints during formulation. For example, it is often necessary that formulations intended to be solid at room temperature be rapidly solidified in order to ensure uniformity and minimize sedimentation. According to the present invention, such rapid solidification may not be required.

Thus, in one embodiment, the invention provides methods for improving optical clarity in oil-containing compositions. Personal care and other formulations that include thickening agents often have an undesirable amount of turbidity. It has been surprisingly and unexpectedly found that the use of a hydrogen-bonding compound in combination with a rheology modifier provides compositions having desired properties for personal care, pharmaceutical or household applications, including viscosity, while also exhibiting reduced turbidity as compared to thickened compositions not containing hydrogen-bonding compounds.

In another embodiment, the invention provides methods for forming, at ambient temperature, oil-based compositions containing polymeric viscosity- modifying agents. It has been surprisingly and unexpectedly found that the use of a hydrogen-bonding compound, such as an alcohol, reduces or eliminates the need for heat in dissolving the viscosity-modifying agent in the oily phase. The methods and compositions of the invention are useful, for example, in forming anhydrous formulations. Such anhydrous formulations can contain ingredients that are unstable, insoluble, or minimally soluble in water, such as, for example, vitamins including vitamins A, C, D and E.

"Personal care compositions", as used herein, includes all oil-containing formulations generally intended for use in the care and/or protection of the skin, hair, nails, mucous membranes, oral cavity or body and generally not used for medicinal or curative effects. As used herein, "personal care" compositions includes cosmetic compositions.

"Household compositions" and "household formulations", as used herein, includes all products used by a consumer in cleaning, repairing, maintaining, remodeling, beautifying, decorating, caring for, improving, or sanitizing a residence and its appliances or contents, contents include kitchen and bathroom fixtures, furniture, dishware, cookware, and clothing.

"Pharmaceutical composition", as used herein, includes compositions comprising drugs, medicaments, medicinal or curative products, tonics, dietary supplements, vitamins, minerals and the like, whether intended to be taken internally or applied topically.

"Topical application", as used herein, includes application of a personal care or pharmaceutical composition to the skin or mucous membrane. "Dermatological formulation" or "dermatological treatment", as used herein, includes all formulations and methods intended for use primarily on the skin, based on their effects thereon, and thus encompasses both cosmetic and pharmaceutical applications.

"Oil", as used herein, includes oils derived from mineral, vegetable, and animal sources. Thus, the term oil is used broadly and includes petroleum oils, such as long-chain hydrocarbons, and silicone oils. For example, compounds containing linear or branched, saturated or unsaturated hydrocarbon alkyl chains of at least about 5 carbon atoms, such as 5, 6, 7, 8 or more carbon atoms, are oils according to the present invention. Thus, such compounds containing hydrocarbon chains of at least 8, 9, 10, 11 , or 12 carbon atoms up to a preferred upper limit of 28, 27, 26, 25, 24, 23, or 22 carbon atoms are oils according to the present invention. "Wax", as used herein, means an organic compound, preferably a hydrocarbon compound, that is solid at room temperature. In addition to hydrocarbons, waxes include fatty acid-alcohol esters.

"Alkyl", as used herein, includes all saturated hydrocarbon moieties, whether straight, branched, or cyclic. "Alkenyl" includes all hydrocarbon moieties, whether straight, branched, or cyclic, containing at least one carbon-carbon double bond. "Alkynyl" includes all hydrocarbon moieties, whether straight, branched or cyclic, containing at least one carbon-carbon triple bond.

"Hydrogen-bonding compound", as used herein, includes all organic compounds containing at least one electronegative atom such as oxygen, nitrogen, or sulfur and capable of forming non-covalent intermolecular bonds by means of the electronegative atoms. Examples include alcohols, amines, and thiols.

"Polar solubility parameter", as used herein, represents the cohesive energy density of a fluid due to dipole-dipole and hydrogen bonding interactions. Calculation of the solubility parameter is described in the discussion of Example 3 below.

Preferred hydrogen bonding compounds according to the invention are those containing one or more hydroxyl groups. Particularly preferred hydrogen bonding compounds are alcohols. Alcohols having a hydrocarbon chain of at least about 8 carbon atoms are preferred, alcohols having a hydrocarbon chain of from about 8 to about 32 carbon atoms are more preferred, and alcohols having a hydrocarbon chain of from about 10 to about 24 carbon atoms are even more preferred. In particular, in cosmetic applications, alcohols having from 12 to 24 carbon atoms are highly preferred. Guerbet alcohols of total chain length from about 12 to about 32 carbon atoms are well known in the art for use in personal care applications, and are useful in the present invention. Guerbet alcohols are 2-alkyl alkanols, such as, for example, 2-butyl octanol, 2-hexyl decanol, 2-octyl dodecanol. Examples of particularly preferred alcohols for use in the present invention are decanol, dodecanol, hexadecanol, stearyl alcohol, butyl octanol, hexyldecanol, and octyldodecanol. If desired, a mixture of two or more hydrogen bonding compounds, such as a mixture of alcohols, can be used. Hydrogen bonding compounds, such as alcohols, can be present in the compositions of the invention in amounts from about 0.1 to about 60 weight percent, preferably from about 0.2 to about 40 weight percent, more preferably from about 0.3 to about 20 weight percent, even more preferably from about 0.5 to about 10 weight percent, based on the total weight of the oil phase of the composition. Preferably, the hydrogen bonding compounds are present at from about 1 to about 5 weight percent, more preferably from about 1 to about 4 weight percent, and still more preferably from about 1 to about 3 weight percent.

Rheology modifiers, according to the invention, are preferably thickening agents, which increase the viscosity of liquids. Rheology modifiers include synthetic polymers and polysaccharides. Modified polysaccharide alkyl, alkenyl, alkynyl, aryl, arylalkyl or arylalkenyl ethers are highly preferred. The modified polysaccharide alkyl, alkenyl, alkynyl, aryl, arylalkyl or arylalkenyl ethers can be neutral or charged.

"Modified", as used herein to describe polysaccharides includes polysaccharide alkyl, alkenyl, alkynyl, aryl, arylalkyl or arylalkenyl ethers, esters, urethanes, amides, carbonates or polysaccharides having any other linkage to the polysaccharide backbone. The modified polysaccharides can have additional substituents which can be cationic, anionic or nonionic. Examples of cationic substituents include quaternary ammonium and phosphonium groups. Examples of anionic substituents include carboxyl, phosphate, sulfate, carboxyalkyl, sulfoalkyl, and phosphoalkyl. Examples of nonionic substituents include alkyl, aryl, and hydroxyalkyl. Also useful as an additional substituent is a substituent group formed by reaction of the polysaccharide ether with an alkyl ketene dimer or with an alkyl succinic anhydride. The additional substituent or substituents can be the same as or different from the first alkyl, alkenyl, alkynyl, aryl, or arylalkyl group. Of the modified polysaccharides, neutral polysaccharides are preferred and of these, modified polygalactomannans are highly preferred. Polygalactomannans are known in the art and are polymers comprising, as polymerized units, galactose and mannose. Polygalactomannans differ from each other, inter alia, in the ratio of galactose units to mannose units. The galactose:mannose ratio is determined, in part, by the source of the galactomannan. Polygalactomannans can be obtained from several sources, including guar, tara, fenugreek, and locust bean gum. For the present invention, modified polygalactomannans derived from guar gum, such as alkyl guar, and especially ethyl guar, are particularly useful. Modified polygalactomannans preferably have a degree of substitution of greater than 2.4. However, other modified polygalactomannans can be advantageously used in the compositions and methods of the present invention. Synthetic polymers useful as rheology modifiers include acrylic acid polymers and copolymers, vinylic polymers such as polyvinyl pyrrolidone polymers and copolymers, polyvinyl acetates, and polyalkenes that are oil soluble.

"Miscible", as used herein, means able to dissolve uniformly in a liquid. "Oily phase", as used herein, refers to a uniform phase, in a uniform or non- uniform composition, which contains the oil or wax. For certain applications, as will be recognized by those skilled in the art, waxes will be preferred. For example, lipstick formulations often contain one or more waxes or solid oils. Similarly, in other applications, oils that are liquids at room temperature will be preferred. In compositions of the present invention, the oily phase can comprise any oil or mixture of oils conventionally employed in personal care, household and pharmaceutical formulations. Such oils include, but are not limited to: hydrocarbons, including the mineral oils, such as the paraffin oils, the petrolatum oils, hydrogenated polyisobutylene, linear or branched hydrocarbons, and triglycerides, particularly vegetable oils. Examples of hydrocarbon oils for use in the present invention include isooctane, isododecane, and isohexadecane. Examples of vegetable oils include sunflower seed oil, sesame seed oil, linseed oil, tung oil, oiticica oil, soybean oil, cottonseed oil, coconut, rapeseed oil, sweet almond oil, calophyllum oil, palm oil, avocado oil, jojoba oil, olive oil, castor oil, and grain germ oils such as wheat germ oil. Other oils include various oily esters derived from a long-chain acid and/or alcohol or polyol, such as purcellin oil; capric/caprylic triglyceride, isopropyl, butyl or cetyl myristate; isopropyl, butyl or ethyl-2-hexyl palmitate; isopropyl, butyl octyl, hexadecyl or isocetyl stearate; decyl oleate; hexyl laurate; propylene glycol dicaprylate; diisopropyl adipate; and the mixtures of C₁₂-C₁₅ alkyl benzoate esters commercially available under the trademark FINSOLV™ TN from Finetex. Also suitable are animal oils, such as perhydrosqualene; and silicone oils, such as dimethylpolysiloxanes, phenyldimethicones, trimethyl phenyl silsesquioxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane, octamethylcyclotetrasiloxane, dimethylcyclosiloxanes, cyclomethicones, alkyldimethicones, and mixtures thereof. Silicone oils are commercially available, for example, from Dow Corning Corporation. Preferred oils, according to the invention, are those having more than about 8 carbon atoms and include, but are not limited to, jojoba, sesame, corn, olive, safflower, and rape seed oils; shea butter, and synthetic oils such as purcellin oil, 2-ethyl hexyl palmitate, 2-octyldodecyl stearate, 2- octyldodecyl erucate, isostearyl isostearate, 2-octyldodecyl benzoate, hydrogenated isoparrafin, and silicone oils.

According to the present invention, the rheology modifier is present in an amount sufficient to achieve the desired thickness for the intended application. In general, it is present in an amount of from about 0.1 % to about 40%, preferably from about 0.3% to about 30%, more preferably from about 0.4% to about 20%, even more preferably from about 0.5 to about 10% by weight, based on the weight of the oil. If the composition is a neat composition, the rheology modifier is present in an amount from about 0.5% to about 8% by weight, based on the weight of the oil. Neat composition, as used herein, is intended to mean a composition that is essentially free of water. If the composition is an emulsion composition, such as, for example, a water-in-oil emulsion, the rheology modifier is present in an amount from about 0.5 to about 10 % by weight, based on the weight of the oil. As will be recognized by those skilled in the art, the amount of rheology modifier for a particular personal care, household or pharmaceutical application will be determined, in part, upon the form in which the composition is to be provided. The compositions and methods of the present invention are useful in a wide variety of products, including personal care, household, and pharmaceutical products. The compositions of the invention can be provided in various forms, such as a liquid, a gel, a solid bar, an emulsion, a paste, an aqueous/alcoholic lotion or dispersion, or an ointment, and can optionally be packaged as an aerosol or dispersed as a foam. The compositions of the invention can contain various additives known in the art including additional rheology modifiers, emulsifiers, thickening agents, such as polyacrylic acids, cellulose derivatives or esters of fatty acids and of polyethylene glycol, sequestering agents, foam reinforcers, preservatives, fragrances, electrolytes, fatty substances such as fatty alcohols, ceramides or mineral, vegetable, animal or synthetic oils or waxes. Amounts of additives and other ingredients can be, for example, from about 0.001% to 20% by weight of the composition. When the compositions of the instant invention are personal care compositions, they may optionally contain additives conventionally used in the personal care industry, including but not limited to active ingredients, perfumes, preservatives, fragrance retention agents, fragrance releasing gels, and sunscreen agents. Such additives and their use in personal care compositions are well known in the art and can be added by known techniques before, during, or after the thickening of the oil. Other ingredients well known to those skilled in the art can also be incorporated into the personal care compositions. Such ingredients include coloring agents, opacifiers, UV screening agents, antioxidants, peariescence agents, biocides, antibacterial agents, antidandruff agents, antiseborrheic agents, antiparasitic agents, repellents, dyes, pigments, oxidizing agents, reducing agents, moisturizers, anionic, nonionic or cationic polymers, vitamins, alpha -hydroxy acids, tocopherol and its esters, fatty esters of ascorbic acid, 18- beta -glycyrrhetinic acid, and ceramides.

When the compositions of the present invention are provided in an emulsion, the emulsion can contain any ingredients known in the art for use in emulsions, such as surfactants and/or dispersing aids. Emulsions can also contain thickeners, which can be, for example, water-soluble or water-swellable polymers contained primarily within the aqueous phase of the emulsion. Examples of suitable water-soluble or water-swellable polymers include: hydroxyethylcellulose, hydroxypropylmethylcellulose, cetyl modified hydroxyethylcellulose_^agar, carrageenans, pectins, guars, hydroxypropylcellulose, crosslinked acrylic acid polymers and copolymers, polyethylene glycols, oxyethylene polymers and copolymers, vinylcaprolactam homopolymers and copolymers, vinylmethyl ether co- maleic anhydride polymers, and polyvinylpyrrolidone.

Powders can be incorporated into compositions of the invention. Examples of powders include chalk, talc, kaolin, starch, smectite clays, chemically modified magnesium aluminum silicate, organically modified montmorillonite clay, hydrated aluminum silicate, fumed silica, aluminum starch octenyl succinate and mixtures thereof.

Personal care products made using the compositions and methods of the present invention are useful in a variety of personal care applications such as, for example, treatment of the skin including moisturizing, cleaning, softening, protecting, hydrating, or smoothing the skin; conditioning, softening, cleansing, or styling the hair; minimizing transepidermal water loss; conditioning or treating the nails, or delivering ingredients including sunscreens, vitamins, pigments, dyes, or tints to the hair, skin and/or nails.

Personal care products for which the compositions and methods of the present invention are suitable include, for example, moisture retention agents, moist towels, towels for cleansing or moisturizing the skin, towels for make-up application or removal, hair styling agents, skin conditioners, hair conditioners, deodorants, including spray, aerosol, gel and stick deodorants, antiperspirants, including spray, aerosol, gel and stick antiperspirants, sunscreen creams or lotions, emollient lotions, milks or creams, make-up removal creams lotions or milks, foundation bases, lotions, milks or creams for artificial tanning, shaving creams, shaving foams, shaving lotions, after shave lotions, face masks, make-up products for the eyes, lipsticks, lip glosses, colors and foundations for the face, shampoos, bath or shower products, hand cleaning products, and compositions for dyeing, bleaching, curling, or straightening the hair. In products such as towels for use in make-up removal or application, the compositions of the present invention can be incorporated within and/or carried on the surface of the towel. Other personal care products, for which the compositions and methods of the present invention are useful, include dentifrices, denture cleaners, denture adhesives, scalp treatment products, blemish treatment products, wound dressings, wound care and treatment products, and oral care products. Such personal care products are generally commercially available to the consumer without a prescription and can be used to treat minor injuries and conditions. Personal care products can optionally contain active ingredients such as antiseptics, anesthetics, and antibiotics, and can be applied to the skin or to the mucous membranes, and can be contained in mucoadhesive compositions. The methods and compositions of the present invention can provide advantages in the use and application of personal care formulations. For example, substantially uniform compositions of the invention can provide for improved distribution of ingredients throughout a formulation, thus providing for improved delivery, including more uniform delivery, of effective or active ingredients to the hair, skin, or nails. Thus, vehicles for the delivery of cosmetic ingredients can advantageously contain compositions of the invention. Examples of ingredients for which the compositions and methods of the invention can provide improved delivery include sunscreens, fragrances, pigments, and agents for treatment of the skin such as those described elsewhere herein. Thus, for example, the methods and compositions of the invention can provide enhanced protection of the skin or hair from the sun by providing for improved delivery of suncreens. This can provide for enhanced protection from the sun, and for protection from ultraviolet and/or infrared radiation, depending in part upon the absorption properties of the sunscreen and/or other radiation-absorbing ingredients in the composition. It is also expected that the methods and compositions can provide for improved delivery of fragrance to the skin, thus enhancing the longevity of fragrance on the skin.

The compositions and methods of the present invention are applicable to household formulations. In such applications, the compositions and methods of the invention can provide advantages in addition to those already mentioned above, in particular, more uniform delivery of effective or active ingredients. Household products for which the compositions and methods of the invention are useful include cleaning products, pretreatment products, products used in remodeling or decorating the home, and sterilizing products. Also included are pet care and grooming products. Also included within "household products" and "household formulations" are products used in cleaning, repairing, decorating or remodeling an automobile, boat, bicycle or other vehicle, and products used in repairs done in a residence by a consumer, such as lubricants for sawing, drilling, or milling wood or metal. Also included are lubricants for household machinery or equipment such as sewing machines and other small appliances. Examples of cleaning products include detergents, stain removers, bleach, glass cleaner, fabric softeners including fabric softener papers, cloths or sponges, oven pretreatment, oven cleaner, cleaners for hard surfaces such as bathroom fixtures and tiles, furniture cleaners and polishes, and cleaners or polishes for wood floors. Remodeling and decorative products include paints, inks, dyes, wood stains, varnishes, and shellacs.

For household applications, other ingredients, in addition to those already mentioned herein, can be present. For example, for household applications, the compositions can contain buffering agents, chelating agents, codispersants, surfactants, enzymes, fluorescent whitening agents, electrolytes, builders, antioxidants, thickeners, fragrance, dyes, colorants, pigments, defoamers, or mixtures thereof. Further examples of optional ingredients include bleach scavengers, sodium perborate, reducing sugars, short chain alcohols; solvents and hydrotropes such as ethanol, isopropanol and xylene sulfonates; flow control agents ,enzyme stabilizing agents; soil suspending agents; antiredeposition agents; anti- tarnish agents; anti-corrosion agents; colorants; abrasives, and other functional additives. The pH of the cleaning composition may be adjusted by addition of strong acid or base. Such buffering agents include sodium carbonate and sodium borate. The compositions and methods of the present invention are also useful in pharmaceutical applications. Pharmaceutical applications generally involve the delivery of a drug or other pharmacologically active agent. As used herein, the term "drug" or "pharmacologically active agent" or any other similar term means any chemical or biological material or compound that induces a desired biological or pharmacological effect, including (1 ) affecting living processes, (2) having a prophylactic effect on an organism and preventing an undesired biological effect such as preventing an infection, (3) treating a disease, including alleviating a condition caused by a disease, for example, alleviating pain or inflammation caused as a result of disease, and/or alleviating, reducing, or completely eliminating the disease from the organism. Pharmaceutical applications thus include materials useful in treating diseases or other conditions of the skin, such as, for example, acne, rashes, fungal, viral or bacterial infections, cracking, peeling, burns, lesions, and dermatitis. Pharmaceutically active agents that can be delivered using formulations comprising the compositions of the present invention, or made according to the methods of the present invention, include antiseptics, anesthetics, vitamins and/or minerals especially those prescribed for medical reasons, and drugs for the treatment of disease. Treatment of disease can be accomplished by administering to a patient in need of such treatment a pharmaceutical composition comprising a composition of the present invention. Such administration can include oral administration, topical application, or administration by means of a suppository. In pharmaceutical applications, the compositions can include such pharmaceutically acceptable additives, ingredients, carriers, extenders, fillers, processing aids, and excipients known in the art. The term "pharmaceutically acceptable carriers" is meant to include any solvents, dispersion media, coatings, and adsorption-delaying agents. Thus, the compositions of the invention can contain conventional excipients known for use in the preparation of pharmaceutical formulations, such as thickening agents, emulsifiers, flavoring agents, coloring agents, and the like.

Examples of pharmaceutical applications for which the compositions and methods of the present invention are useful include formulations intended for ingestion and formulations intended for topical application. Ingestible pharmaceutical formulations for which the present invention is useful include dosage forms such as capsules, caplets, tablets, liquids, and gels. Topically applied pharmaceutical formulations for which the invention is useful include creams, lotions, gels, adhesives, ointments, and formulations for transdermal delivery of pharmaceutically active materials. For transdermal delivery, chemical enhancers for facilitating transport of the drug through the skin or mucosa and other additives can be included in the composition.

Various modifications of the invention, in addition to those described herein, will be apparent to those skilled in the art from the foregoing description. Such modifications are intended to fall within the scope of the appended claims.

EXAMPLES

The following examples are merely illustrative of the present invention and should not be considered limiting of the scope of the invention in any way. These examples and equivalents thereof will become more apparent to those skilled in the art in light of the present disclosure and the accompanying claims.

Example 1

Optical clarity of mixtures containing an alkylgalactomannan, N-Hance® AG-200 polymer from Hercules Incorporated was determined by turbidity measurements. The mixtures were N-Hance® AG-200/alcohol/organic solvent mixtures in which various levels of polymer (AG-200), alcohol (dodecanol or hexadecanol), and organic solvent (Finsolv TN, isopropyl palmitate, or 50:50 FinsolvTN:isopropyl palmitate) were combined. Mixtures were prepared by first mixing appropriate weights of the solvent components (note: hexadecanol and cetyl alcohol are solid at room temperature) and adding an appropriate weight of N- Hance® AG-200 alkyl galactomannan. The mixtures were heated to 70-85°C for approximately one hour to speed dissolution of the polymer. Sample turbidity was determined using an Orbeco-Hellige model 966 turbidimeter. Samples were contained in Wheaton disposable glass scintillation vials. Turbidity data is presented in Table 1. It is apparent from the data in Table 1 that, as the concentration of polymer increases, the turbidity of the resulting solution increases. It is also clear the addition of a long chain alcohol can serve to lower the turbidity of the resulting solution, yielding an aesthetically improved result.

Example 2

Mixtures of N-Hance® AG-200 polymer, or N-Hance® AG-50polymer, and decanol were prepared and allowed to stand. Upon standing, the polymer became highly swollen by the alcohol. At low levels of polymer, the solute completely swelled while at higher levels excess unsolvated polymer remained. Results are presented in Table 2.

Table 2 N-Hance ®AG Polymer/Decanol Swelling and Uptake

The results indicate that gels or viscous solutions containing about 30 to 40 weight percent polymer can be prepared.

Example 3

A solution was prepared of N-Hance AG® polymer in 2-butyl octanol (25 wt % N-Hance AG® 50 polymer or 20 wt % N-Hance AG® 200 polymer). 1 or 2 grams of the polymer solution was accurately weight in a scintillation vial. 0 or 2 grams of 2- butyl octanol was accurately weighed into each vial.

Primary solvent was accurately weighed into each vial to yield a final total volume of approximately 20 ml. Primary solvents used were: DC-345 (Dow Corning cyclodimethicone), DC-556 (Dow Corning Phenyl trimethicone), P-99A (Permethyl Specialties isododecane), P-101A (Permethyl Specialties isohexadecane). The solvent, polymer, and alcohol were mixed with a magnetic stirrer and heated on a hot plate (95°C) for 1 hour to yield nominal polymer concentrations of 1 -1.5 and 2- 2.5 weight percent with 2-butyl octanol concentrations of 2-10 and 12-24 weight percent. Solution viscosities were measured using a Brookfield LVDV-II+ viscometer with a small sample adapter and a #18 spindle. 8 ml of each sample was added to the sample reservoir of the viscometer and thermostatted at 25°C. The spindle rotation rate was set to the maximum rotation rate that resulted in an on-scale reading. The sample turbidity was directly measured using an Orbeco-Hellige turbidimeter.

Solubility parameters were calculated using volume fraction mixing rules (δ_{d mιx} = ψ₂-butyi octanol " ,₂-butyl octanol ψpπmary solvent "d.pπmary solvent' "p.mix ^— τ₂-butyl octanol ^p.ϋ-butyl octanol Ψpnmary _solvent δ_{p,pπrnary solven},). Component solubility parameters used are listed in Table 4. Also listed in Table 3 are the turbidity, viscosity, and appearance of each composition. Solubility parameters used are those described in CM. Hansen, "The Three- dimensional Solubility Parameters", J. Paint Technol., Vol. 39, p. 105 (1967).

* "AG-200" = N-Hance® AG 200 alkyl galactomannan polymer; "AG-50" = N-Hance® AG 50 alkyl galactomannan polymer.

Table 4 Solubility Parameters for Solvents Used in Example 3

A δ_p value of 0 was assigned to DC-345 and DC-556 based on the solvatochromic response of dimethylsiloxane polymers and low molecular weight linear dimethyl siloxanes relative to linear and cyclic alkanes (see J. E. Brady, D. Bjorkman, C. D. Herter, P. W. Carr; Analytical Chemistry (1984) 56, 278-83 and references cited therein.). δ_d values were calculated from the measured refractive index of the liquids using the relation δ_d = 62.78 ^*(n² - 1 )/(n² + 2) (J/cc)^1/2, where n is the refractive index of the pure liquid. The solubility parameters of 2-butyl octanol and 2-hexyl decanol were obtained from European patent No. 0,795,322,A1. δ_totai ⁼ (^δ _d ^{+ δ} _p )^{1/2 =} (-ΔE_vapΛ/)^1/2 where δ_totaι, δ_d, and δ_p are the total, dispersive, and polar solubility parameters, -

Procedure:

The petrolatum and mineral oil were weighed into a 250 ml beaker. The beaker was placed in a circulating oil bath heated to 67°C. The contents were stirred at speed 0 with an electric mixer having two VΛ" dia. propellers spaced VΛ ' apart on the shaft. When contents were 65°C, the polymer was added slowly while adjusting the mixer speed to maintain a vortex in the mixture. Mixing was continued for one hour.

Clear Stick Antiperspirant A two phase method was used to prepare the clear stick antiperspirant as follows:

Phase I

About 65% of the total propylene glycol used (excluding that which is part of the antiperspirant salt solution) was charged to a reaction vessel. Klucel® GF was added to the vessel and stirred well until dissolved. The vessel was heated to dissolve the polymer. Once the polymer was dissolved, the solution was heated to 110°C-115°C, and the dibenzylidine sorbitol was added and mixed until completely dissolved. This Phase I solution was then cooled to about 100°C. Phase II

About 35% of the total propylene glycol used (excluding that which is part of the antiperspirant salt solution) was added to the another vessel, stirred and heated to about 60-70°C. The Na₄EDTA was added and mixed well to form a slurry. The antiperspirant salt solution was added next to this vessel and the solution was mixed well until it becomes clear and homogeneous. The emollients, dimethicone copolymer, was added and the Phase II solution was mixed until it became clear.

Combined Phase: Phase II was added to Phase I while mixing and cooled to 80°C. Optionally, a fragrance would be added at this point and allowed to mix well. The product was poured into a 1 oz. glass jars and allowed to cool overnight. After cooling overnight, the samples were tested for physical and chemical properties.

Equipment Used:

Two 400 ml glass beakers, oil bath, clamps, mechanical stirrer, Jiffy stirrer and thermometer, and a covering to prevent contamination, such as plastic wrap.
