SUMMARY OF THE INVENTION

In accordance with some aspects of the present invention, a wide range of functionalized crystalline polymers with a side chain (SCC) can be used to thicken the oils, provided that the SCC polymer dissolves in the oil at a temperature above the melting point of the polymer crystal (referred to herein as T _p ), and can crystallize when the polymer solution in the oil is cooled to a temperature that is lower than T _p and at which the thickened oil composition is to be used. Without the desire to be bound by any theory, it is believed that the SCC polymer crystallizes into a network in which polymer crystals are connected to each other by semi-soluble chains.

In one aspect of the invention, the invention relates to personal care compositions and to a method for producing and using a composition in which the SCC polymer has at least one functional group selected from the group consisting of silicon, hydroxyl and carboxyl. Such functionalized polymers can be used in a wide range of personal care compositions, including, but not limited to, other personal care products, skin care products, body cleansers, shampoo, hair styling and hair treatments (e.g. hairstyle cream, cream and lipsticks for combing hair, aerosols for hair, hair dyes), sunscreens, lipsticks, sweat products, deodorants, shaving products and after shaving. The amount of SCC polymer, along with other beneficial effects, is sufficient to thicken, modify rheology, film formation, enhance aesthetics or sensory or tactile sensations, in particular, the effect of silicone.

In another aspect, the invention relates to a method for producing a composition comprising

(i) dissolving the SC polymer in oil at a temperature above T _p , and

(ii) cooling the solution to crystallize the polymer in oil.

In another aspect of the invention, the advantage of using these SCC polymers as thickening agents, in particular in emulsions of water in oil, water in silicone, silicone in water or multiphase emulsions, for example, oil / water / oil or oil / water / oil, consists in that the need for a surfactant and any other thickener for the aqueous or oil phase or rheology modifier other than SCC is reduced or eliminated. Thus, the compositions may contain less than 5%, usually less than 2%, usually less than 1%, and in some cases about 0% surfactants or other thickeners or rheology modifiers of the oil phase or aqueous phase, and percentages presented by weight based on the weight of the oil. This is especially useful in cosmetics and personal care products, because such products usually contain surfactants (for example, perfluoroalkylorganic compounds), and surfactants can cause an adverse reaction in contact with human skin.

DETAILED DESCRIPTION OF THE INVENTION

Above in the section "Brief description of the invention" and below in the sections "Detailed description of the invention", "Examples" and "Claims" reference is made to specific aspects of the invention. It should be understood that the description of the invention in the present description includes all suitable combinations of such specific features. For example, when a particular aspect or feature is disclosed in the context of a specific embodiment or a specific patent claim, that feature can also be used to a practical extent in the context of other specific embodiments and patent claims, and in the invention as a whole.

7) the ability to enhance the SPF (sun protection) of sunscreens,

8) the ability to provide air-permeable film when applying cosmetic compositions to the skin,

9) the properties of the film can be enhanced and converted into a more occlusive film (retaining moisture) in combination with other polymers forming the film, soluble in the oil or water phase, along with this polymer,

10) the ability to provide retention of aroma and retention of volatile ingredients,

11) the ability to make layered gels more waterproof without increasing their viscosity,

12) the ability to make waterproof emulsions based on alcohol and / or non-ionic ethoxylated emulsifiers,

13) sensory and textural advantages can, along with other advantages, be modified and enhanced using various functionalities of SCC polymers, which are understood by the average person skilled in the art.

Polymer Thickeners

The FSCC and / or SCC polymers used as thickeners in the present invention can be homopolymers or copolymers of two or more comonomers, including random copolymers, graft copolymers and block copolymers (including thermoplastic elastomers). Two or more SCC polymers can be used together. The number average molecular weight of the SCC polymer as a whole is from about 10,000 to about 1,000,000, typically from 12,000 to 1,000,000. The molecular weight of the SCC polymer is relatively unimportant for its T _p , but generally represents an important factor in determining T _{p of} other polymers.

SCC polymer usually melts within a relatively small temperature range. The SCC polymer usually has a melting point onset, T ₀ , so that T _p - T _{0 is} less than T _p ^0.7 , generally less than T _p ^0.8 , in particular less than 10 ° C, especially less than 6 ° C, with T ₀ and T _p presented in ° C. The crystallinity of the SCC polymer is usually such that its specific heat of fusion is at least 20 J / g, in particular at least 40 J / g.

The SCC polymer can, for example, be prepared from one or more acrylic, methacrylic, olefin, epoxy, vinyl, ester-containing, amide-containing or ether-containing monomers. SCC polymers can include repeating elements in which the side chains include linear polymethylene radicals containing from 10 to 50, for example, 16-50, in particular from 16 to 22 carbon atoms. Polymers containing such elements can be prepared by polymerizing a monomer component comprising one or more corresponding linear aliphatic acrylates, or methacrylates, or equivalent monomers, such as acrylamides or methacrylamides. A number of such monomers are commercially available, either as individual monomers or as mixtures of identified monomers, for example, C12A, C14A, C16A, C18A, C22A, a mixture of C18A, C20A and C22A, and a mixture of C26A to C40A. The polymers may also contain elements derived from one or more other comonomers, for example, straight or branched chain acrylacrylates or methacrylates in which the alkyl group contains less than 12 carbon atoms, and monomers containing suitable functional groups, for example, functional groups including at least one member selected from the group consisting of carboxyl or hydroxyl groups containing oxygen, nitrogen or silicon, and, among other functionalities, cationic functionality (qua thinned compounds, such as compounds containing nitrogen), dimethylamines (e.g., arylamide). Such monomers include, for example, the monomers listed above. In the list below, the term (meta) acrylate means that the compound can be either acrylate or methacrylate:

(a) Nitrogen-containing monomers, for example, N, N-dialkylamine (in particular dimethylamino) (meth) acrylates; (meth) acrylates containing an ammonium salt, for example, 2-trimethylammonium methacrylate chloride, for example, methacrylamide propyltrimethylammonium chloride, N, N- (diethyl or dimethyl) aminoethyl (meth) acrylate chloride; imides, such as ring products of maleic or itaconic anhydride with primary amines; 2-methacryloxy-N-ethylmorpholine; 2-t-butylaminoethyl methacrylate; (meth) acrylonitrile; t-butylaminoethyl (meth) acrylate; acryloylmorpholine; N- (2-hydroxyethyl) acetamide; 1-piperidinethyl (meth) acrylate; vinylpyrrolidone and vinylpyridines.

(b) Oxygen-containing monomers that are substantially free of carboxylic acid groups, carboxylic acid salt groups, sulfonic acid groups, sulfonic acid salt groups, and amino groups, for example hydroxyalkyl (in particular hydroxyethyl, hydroxypropyl and hydroxybutyl) (meth) acrylates ; tetrahydrofurfuryl (meth) acrylate; glycidyl methacrylate; alkoxyalkyl (meth) acrylate, e.g. methoxyethyl (meth) acrylate); 1-acryloxy-2-hydroxy-3-phenoxypropane; methylol methacrylate; ethoxyethyl (meth) acrylate; 2- (2-ethoxyethoxy) ethyl acrylate; acetoacetoxyethyl (meth) acrylate; phenoxyethyl (meth) acrylate and (meth) acrolein; vinyl alcohol; vinyl ethers and vinyl esters.

(c) Silicon-containing, for example, silyl, monomers, for example, trimethylsiloxyethyl (meth) acrylate, 3-acryloxypropyltrimethoxy silane, limited chain polydimethylsiloxane monomethylmethacrylate, and 3-acryloxypropyltris (trimethylethoxy) silane.

When the SCC polymer includes a graft or block copolymer, it can be obtained by copolymerizing a vinyl type macromonomer with other monomers, or by preparing a SCC polymer and then reacting the functionalized polymer with a second block material, for example, a urethane block, an epoxy block, a polyester block, for example polyethylene oxide, polypropylene oxide or polytetramethylene oxide block, polysiloxane block or poly (alkyl or alkoxy) silane block, or it can be obtained using any other suitable polymerization aids, such as emulsion or suspension polymerization in the presence of surfactants and / or colloids, or block polymerization or polymerization in solvents. Non-limiting examples of surfactants include at least one member of cetart, laureth, pareth, PEG (polyethylene glycol) and / or PPG (polypropylene glycol) or POE (pivaloyloxyethyl) esters, and sorbitanoleate ethers. Octylphenyl and / or nonylphenyl ester and sulfosuccinate, sodium or disodium salts, like disodium-C-isodecyl sulfosuccinate, sodium isostearate, esters or ethers of natural and synthetic oils and waxes, like, among others, PEG and / or PPG hydrogenated castors. Non-limiting examples of colloids include at least one member of stearyl alcohols; behenyl alcohol; modified and unmodified resins like carginans, celluloses, carbomers; PVP (polyvinylpyrrolidone); hydrogenated and, among others, hydrolyzed waxes and / or oils.

The SCC polymer may contain sufficiently long chain groups so that it dissolves in oil at temperatures above T _p . When the SCC polymer is used to thicken an oil or oil mixture that is devoid of water, the polymer as a whole contains at least about 50%, usually at least about 60%, in particular at least about 70%, especially at least about 80% elements comprising a linear radical containing from about 10 to about 50 carbon atoms, and may contain up to 100% of such elements. In particular, when an SCC polymer is used to thicken an emulsion of water in oil, or water in silicone, or a multiphase emulsion. It may contain at least about 5%, usually at least about 10% of elements derived from a monomer containing a functional group, such as at least one of hydroxyl, COOH and silicone functional groups and may contain higher amounts (e.g. up to 25% or 30% wt.), provided that the SCC polymer will at least partially dissolve in the oil.

In one aspect of the invention, the SCC polymer consists essentially of

(i) 70-99% wt. repeating elements derived from at least one ester of n-alkyl acrylate or methacrylate, in which the n-alkyl group contains from 16 to 22 carbon atoms,

(ii) 1-50%, usually 15-25% wt. repeating elements derived from at least one ester of acorylate or methacrylate in which the ester group contains a hydroxyl substituted alkyl group containing less than 12 carbon atoms, and

(iii) 0-30% wt. repeating elements derived from at least one ester of acrylate or methacrylate, in which the ester group contains an unsubstituted alkyl group containing less than 16 carbon atoms to reduce Tr.

Suitable polymers within the framework of the previous aspect may include SCC polymers consisting essentially of

(i) 70-99% wt. repeating elements derived from at least one ester of n-alkyl acrylate or methacrylate, in which the n-alkyl group contains from 16 to 22 carbon atoms, and

(ii) 1-50%, usually 15-25% wt. repeating elements derived from at least one ester of acrylate or methacrylate, in which the ester group contains a hydroxyethyl, hydroxypropyl or hydroxybutyl group.

In another aspect of the invention, the SCC polymer consists essentially of

(i) 70-99% wt. repeating elements derived from at least one ester of n-alkyl acrylate or methacrylate, in which the n-alkyl group contains from 16 to 22 carbon atoms,

(ii) 1-50%, usually 15-25% wt. repeating elements derived from at least one silicon-containing monomer containing less than 12 carbon atoms, and

(iii) 0-30% wt. repeating elements derived from at least one ester of acrylate or methacrylate, in which the ester group contains an unsubstituted alkyl group containing less than 16 carbon atoms to reduce Tr.

Suitable polymers in the framework of the previous aspect may include SCC polymers consisting essentially of

(i) 70-99% wt. repeating elements derived from at least one ester of n-alkyl acrylate or methacrylate, in which the n-alkyl group contains from 16 to 22 carbon atoms, and

(ii) 1-50%, usually 15-25% wt. repeating elements derived from at least one silicon-containing monomer, including an element from at least one of butyl dimethicone methacrylate, trimethylsiloxyethyl (meth) acrylate, chain limited polydimethylsiloxane monomethylmethacrylate, or 3-acryloxypropyltrimethylethoxysilane.

In yet another aspect of the invention, an SCC polymer consists essentially of

(i) 70-99% wt. repeating elements derived from at least one ester of n-alkyl acrylate or methacrylate, in which the n-alkyl group contains from 16 to 22 carbon atoms,

(ii) 1-50%, usually 15-25% wt. repeating elements derived from at least one monomer containing a carboxyl group (COOH) containing less than 12 carbon atoms, and

(iii) 0-30% wt. repeating elements derived from at least one ester of acorylate or methacrylate, in which the ester group contains an unsubstituted alkyl group containing less than 16 carbon atoms to reduce Tr.

Suitable polymers in the framework of the previous aspect may include SCC polymers consisting essentially of

(i) 70-99% wt. repeating elements derived from at least one ester of n-alkyl acrylate or methacrylate, in which the n-alkyl group contains from 16 to 22 carbon atoms, and

(ii) 1-50%, usually 15-25% wt. repeating elements derived from at least one monomer consisting of a list of acrylic acid, methacrylic acid or maleic anhydride.

The molecular weight and other properties of the SCC polymer can be sufficiently controlled so that the polymer crystallizes in oil after it is dissolved in oil, when the heated mixture is cooled to the expected temperature of use, for example, to a temperature of 10-20 ° C below T _p , causing thus, obtaining a cloudy or clear mixture.

T _p thickening polymer is generally at 10-40 ° C higher, in particular at 10-30 ° C higher, especially about 20 ° C above the temperature at which the composition is to be used, which generally is 15-40 ° C. It seems that the oil plasticizes the thickening polymer, so that its melting point is, for example, 5-20 ° C lower than T _p . Therefore, it is desirable that T _p be sufficiently higher than the temperature when used to ensure that the thickening polymer does not melt during use. Thus, for compositions to be used at a temperature of about 20-35 ° C, the thickening polymer may have a T _p above 40 ° C, typically 40-70 ° C. On the other hand, if T _{p of the} thickening polymer is much higher than the temperature of use, this can lead to excessive crystallization and then precipitation of the polymer, thereby reducing the thickening effect. Therefore, it is desirable that T _p be not more than about 30 ° C higher, usually not more than 20 ° C higher than the temperature of use. Depending on the expected temperature of use, T _p can be from 0 to 150 ° C, in general, 10-100 ° C, usually 40-70 ° C, preferably 43-55 ° C.

The amount of polymer thickener used may vary depending on the application. Usually it is not necessary that the amount of thickener is more than about 10% wt. based on the mass of oil. Smaller amounts are often effective, such as from about 2 to about 7% based on the weight of the oil in compositions that are devoid of water, and from about 0.5 to about 5% based on the weight of the composition in the form of an emulsion of water in oil, water in silicone, or multiphase emulsions. In one aspect of the invention, the amount of polymer thickener is sufficient to form an emulsion (for example, an emulsion of water in oil or oil in water) having enhanced rheology and sensory properties. These properties can provide a sunscreen emulsion for skin care having the properties of enhanced film formation on the skin and, in turn, increase the SPF of the sunscreen.

In another aspect of the invention, the amount of polymer thickener is selected to give the cosmetic composition enhanced water / moisture and abrasion resistance.

In yet another aspect of the invention, an amount of polymer thickener is selected to impart moisture retention or occlusivity properties to a skin care cosmetic product.

In another aspect of the invention, the amount of polymer thickener is sufficient to provide an increased or controlled release of the active ingredient of the cosmetic composition, for example, by incorporating the active components in the cosmetic medium into an amorphous crystalline matrix structure and releasing the active components in a controlled manner at or near body temperature. For example, the composition of the invention may include an FRSCC and / or SCC polymer containing an antiperspirant or deodorant composition, or the composition may include one active ingredient, such as sunscreen, active ingredient, or salicylic acid, or any other active cosmetic / personal care agent, used in anhydrous or emulsion formulations.

Oils

Functionalized polymer thickeners are effective with a wide range of oils, such as at least one member selected from the group consisting of, among others, esters (C12-15 alkyl benzoate), triglyceride (caprylic / caprylate triglyceride), hydrocarbons (mineral oil, oil sunflower), natural oils (jojoba oil, safflower oil), castor oil. Suitable oils are also described, for example, from line 37 of column 3 to line 4 of column 4 of US patent No. 5736125, incorporated herein by reference. To thicken silicone oils, you can use an SCC polymer containing elements derived from a monomer containing silicon, for example, a block copolymer containing SCC blocks and polysiloxane blocks.

SCC polymers / polysiloxane of this type are described, for example, in WO 93/07194 and WO 00/04787, incorporated herein by reference. Non-limiting examples of silicone oils may include at least one compound of dimethicone, polydimethylsiloxane, organosilicon oils, and cyclomethicones. In one aspect of the invention, SCC polymers are used as rheology modifiers (e.g., a thickener) for at least one of dimethicone, cyclomethicone and other low viscosity silicone oils.

In one aspect of the invention, functionalized SCC thickened oils provide a cosmetic formulation having exceptional aesthetic benefits (e.g., texture and tactile feel). In some cases, a functionalized SCC may be combined with one or more SCC polymers. The ratio of SCC to functionalized SCC can range from about 0: 1 to about 10: 1.

The viscosity of the chilled product in centipoises was determined using a Brookfield DV-I + digital viscometer with a CP-51 spindle, using a sample adapter that was thermostatically controlled, for example, at 25 ° C. Viscosity values were measured after 4 minutes at a speed of 2.5 rpm, i.e. after 10 revolutions. In Examples 7-12, the oil (as identified in Table 2), 14 parts, was heated to 20 ° C, and 0.75 parts of the thickener were dissolved in it. 35 parts of water containing 0.25 parts of MgSO ₄ .H ₂ O were heated to 80 ° C. Oil and water, both ingredients at 80 ° C, were mixed together and then cooled to 25 ° C with continued stirring. The product, a milky white emulsion of water in oil, was left overnight and then its viscosity was measured at 25 ° C using a Brookfield flat conical viscometer. Viscosity was measured after 0.5, 1, 2, and 4 minutes to evaluate the effect of shear on the emulsion.

Other examples illustrate formulations of compositions comprising functionalized SCC or / / SCC polymers. These examples illustrate personal care formulations, including but not limited to skin care creams, sunscreens, body cleansing compositions (e.g., shower mousse), and hair care compositions (e.g., for styling and conditioning hair).

EXAMPLES

Examples 1-12

Polymers and copolymers were prepared using the ingredients and their amounts shown in the table below, using the following generalized method. In a resin boiler equipped with a distillate stirrer and condenser, 20% of monomers and chain transfer agents were added. The mixture in the resin boiler was heated to 110 ° C, and oxygen was removed from the system by purging with nitrogen for about 30 minutes, followed by the addition of 20% of the initial initiator charge. After providing sufficient time to terminate the initial exothermic reaction, the remaining monomers, chain transfer agents, and the initial initiator were injected into the reaction vessel for 60-90 minutes. The polymer mixture was allowed to continue reaction for 60 minutes, followed by the addition of a displacement initiator and reaction for 60 minutes. The mixture was kept under reduced pressure for 60 minutes to remove volatile residuals. The resulting polymers were generally yellow to white solids. The molecular weight, T _p , and viscosity of each sample were measured. The effectiveness of the polymers as thickeners was measured as described above, and the results are shown below in tables 1 and 2.

The following abbreviations are used in the tables. ME = mercaptoethanol; MA = methacrylic acid; DMAEA = N, N-dimethylaminoethyl acrylate; HEA = 2-hydroxyethyl acrylate; TAPO = t-amylperoxy-2-ethylhexonate sold by Witco as Esperox 570P, 75% active in liquid; TBPB = t-butyl peroxybenzoate sold by Witco as Esperox 10; Estol is propylene glycol dicaprylate / caprate sold by Uniqema under the trade name Estol 1526; Min'l is a mineral oil; and opq = opaque in appearance.

In Example 2, inside the HPIB oil, the polymer had a T _p above the desired range, resulting in excessive crystallinity and low thickening under test conditions. However, in other oils (for example, isopropyl palmitate or isopropyl myristate) sufficient plasticization T _p for the polymer of Example 2 can still lead to effective thickening. In Example 4, inside the HPIB oil, the polymer had a T _p below the desired range and was ineffective as a thickener under test conditions because it did not crystallize after cooling. However, the polymer of Example 4 could still provide the advantages of thickening or film formation inside the oil, where there was a slight plasticization (for example, mineral oil or ethanol).
