Description

Field of the invention

The Invention is in the field of finishing textiles and concerns a spray container with its help microencapsulated agents on the surface of garments let raise.

State of the art

Under The term "comfort" are increased requirements summarized by the consumer who is no longer alone with it want to satisfy that of him directly on the skin worn linen, such as lingerie or tights, but also jeans, neither scratch nor cause skin redness, But quite the other way, they are expected to be positive about the condition affects his skin. These may be both fatigue symptoms to remedy, as well as to convey a fresh scent or skin roughness to avoid. There was therefore no lack of effort, Textiles and again especially women's tights - this seems to be a particularly attractive consumer field - with to equip cosmetic active ingredients when wearing on go over the skin and there the desired effects cause. Now it is in the nature of things that the desired Effects only come about if the corresponding active ingredient transferred from the wearer to the skin, d. H. to A more or less long wearing time is on the garment no active ingredient left. This puts to the manufacturer such Products certain requirements in the selection of active ingredients, because under Balancing performance, applicable quantity and last but not least the associated costs, he must find a compromise that enables a product whose effect can be experienced and whose increased price can also be paid by the customer. Because cosmetic agents that have the desired effects have, are usually expensive and also the equipment the end products are associated with additional costs, It is of particular importance to the manufacturer that it except by the contact between the equipped Endpro duct and the skin of the wearer not to further unwanted Loss of active ingredients comes as this would cause that the customer paid dearly additional comfort over a shorter time becomes effective. A particularly undesirable Form of drug loss occurs in the context of the laundry the so-equipped fibers and textiles. Even if These losses can not be completely avoided, so is it is obvious that it is a particular concern of the manufacturer corresponding products, the active ingredients in such a way apply the fibers so that they do not dissolve readily or mechanically detached.

One solution to this problem is the use of microencapsulated agents, which are either incorporated between the fiber fibrils or applied to the fibers with the aid of binders. Such systems are for example from the publications EP 0436729 A1 . WO 01/098578 A1 . US 6,355,263 . DE 2318336 A1 such as WO 03/093571 (all Cognis) known.

DE 10 2005 045 138 A1 (Cognis) describes aqueous microcapsule dispersions comprising a) water, b) microcapsules which are loaded with one or more ingredients or active ingredients, and c) polymeric dispersants, which polymers may be homopolymers or copolymers, and wherein said polymers comprise at least 5 monomer units are constructed.

Alternatively, the active ingredients can also be applied directly with the aid of film-forming polymers, which is known as so-called "composite finishing" and is the subject of DE 10 2004 037 752 A1 (Cognis) is.

Ultimately, however, it can not be prevented that the amount of microcapsules, with which the textiles have been equipped, constantly decreases during the washing cycles, until an effect can no longer be determined. There is therefore a need to renew the equipment, which is commonly referred to as "reload". For this purpose, for example, in the DE 10 2007 001 115 A1 (Cognis) proposed to treat the textiles with aqueous emulsions and / or dispersions containing skin-care oils, drug-loaded microcapsules, emulsifiers, foaming agents and stabilizers. However, this is foam application, ie the preparation is applied to the textile and then massaged into the fibers by intensive rubbing. This type of use has proven to be less customer friendly in practice.

In this context, it should also be on the DE 10 2005 059 721 A1 (Cognis), are known from the emulsions for the care of textiles, which by spray application on the textiles are applied.

Ultimately However, it turns out that the problem of reload, i. H. reloading of textiles with cosmetic active ingredients in a way that simultaneously efficient and customer friendly, is not solved. The task The present invention thus has stood in be, just this To remedy problems and provide a solution which also meets high ecological requirements.

Description of the invention

• (a) einem äußeren Behälter,
• (b) einer mit dem äußeren Behälter verbundenen Sprühvorrichtung,
• (c) einem inneren Behälter, welcher mit der Sprühvorrichtung verbunden ist, sowie
• (d) einer im inneren Behälter enthaltenen wässrigen oder alkoholischen sowie gegebenenfalls ölhaltigen Zubereitung mit einem Gehalt an mit kosmetischen Wirkstoffen beladenen Mikrokapseln sowie
• (e) gegebenenfalls einer mechanischen Pumpvorrichtung.

The invention relates to spray containers, consisting essentially of

• (a) an outer container,
• (b) a spraying device connected to the outer container,
• (C) an inner container, which is connected to the spray device, as well as
• (D) a contained in the inner container aqueous or alcoholic and optionally oil-containing preparation containing a loaded with cosmetic active ingredients microcapsules and
• (e) optionally a mechanical pumping device.

Surprisingly has been found to be microencapsulated agents for The reload of textiles from consumers quickly, effortlessly and safely apply, if appropriate aqueous Preparations containing these substances, using special Apply spray container. For this purpose come special ones Microcapsule emulsions or dispersions are used and are Used containers that work with pure compressed air and so the Do not burden the environment. By the way, the containers can be left also spray over head.

The outer container

In its simplest, yet preferred embodiment the outer container is a conventional one Aerosol can, for example made of aluminum or tin can be made. The capacity is typically between 50 and 500 ml; larger volumes are possible, corresponding containers but less handy, smaller ones can also be used, the capacity Of course, it is very limited.

The spraying device

at the spray device is usually around a spray head or a spray nozzle, as used in all conventional spray cans Find. By pressing the spray device is the valve is opened and the pressurized preparation can escape.

The inner container

in principle it is possible to the outer container directly to fill with the preparations, with propellants to fill and then the active ingredients by pressing the sprayer as a result of prevailing in the container To spray internal pressure. That way save the inner container; the system would be also much cheaper to produce. If the the present invention nevertheless such an inner container especially for reasons of environmental compatibility: Propellants such as propane or butane are flammable and therefore undesirable, The filling with carbon dioxide also comes from ecological Reasons not considered.

The preferred embodiment of the present technical Teaching therefore provides an inner container in the form of a pressure-resistant Beutels, such as made of special polyethylenes or polypropylene materials is commercially available. Such bags can be easily in the outer container insert and either directly with the sprayer or indirectly via a pressure hose (so-called "bag-on-valve" systems). They also have the advantage that they are chemically inert, d. H. there is no danger that the active substance preparations or the contained therein solvents attack the material of the bag, so that the preparation could leak into the container.

After inserting inner container - especially the bag - and the spray device on the outer container of the space between the inner and the outer container is pressurized. For this purpose, it is usually necessary to press 2 to 3 bar of compressed air. After checking the compressive strength, the preparation is then pressed into the bag at a pressure of 5 to 10 bar. It may be beneficial to mecha previously in the bag to fill in niche mixing aids. These are preferably small metal or plastic balls that help shake the container to homogenize the preparations - if necessary - to homogenize. After filling the inner container, the filling weight is usually checked, the container capped and then ready to use. Such systems are available for example under the name "EPSraySystem ^®" by the company EP Systems SA in the trade.

The preparations

at The preparations may be aqueous, alcoholic or act aqueous alcoholic systems. In these can also be included cosmetic oils. Accordingly, you can the preparations as dispersions or emulsions, especially also present as PIT emulsions. To ensure reliable sprayability To ensure the preparations should have a viscosity of less than 25 mPas and the microcapsules contained therein average diameter of less than about 30 microns, preferably less than about 20 μm, and in particular less than have about 10 microns. Conversely, it has to be sure a satisfactory cosmetic effect has proven to be advantageous, if the microcapsule content in the preparations ranges from 5 to 20 wt .-% - based on the preparation - is.

These substances can be used individually or mixed with each other.

The microencapsulation

For the feasibility of the invention is the nature of the microcapsules only limited critical: as long as this sufficient surfactant stability have, for the encapsulation of the corresponding active ingredient are actually suitable and their average diameter in the specified range of a maximum of 30 microns, they can Find application. Of course that does not close from that the quality of the final products does not last is very dependent on the nature of microcapsules, because under the spray conditions, some capsule types prove as more suitable - because more stable - than other. This was not predictable, but only by extensive To determine test series.

Under the terms "microcapsule" or "nanocapsule" from the expert spherical units with a diameter in the range of less than 50 microns or 500 nm understood, the contain at least one solid or liquid core, which is enclosed by at least one continuous shell is.

Gelling agents. As gelling agent preferably such substances are considered, which the property show up in aqueous solution Temperatures above 40 ° C gels to form. typical Examples include heteropolysaccharides and proteins. As thermogelierende heteropolysaccharides are preferably agaroses in question, which in the form of the agar-agar to be extracted from red algae also together with up to 30% by weight of non-gel forming agaropectins may be present. Main component of the agaroses are linear polysaccharides from D-galactose and 3,6-anhydro-L-galactose, alternating β-1,3- and β-1,4-glycosidically linked. The heteropolysaccharides preferably have a molecular weight in the range of 110,000 to 160,000 and are both colorless and tasteless. As alternatives come pectins, xanthans (also xanthan gum) and their mixtures in question. Furthermore, preference is given to those types which are still present in 1% by weight aqueous solution gels that are not below from 80 ° C and melt already above 40 ° C consolidate again. From the group of thermogeling proteins may be mentioned by way of example the various types of gelatin.

Cationic polymers. Suitable cationic polymers are, for example, cationic cellulose derivatives, such as. Example, a quaternized hydroxyethylcellulose obtainable under the name Polymer JR 400 ^® from Amerchol, cationic starch, copolymers of diallyl ammonium salts and acrylamides, quaternized vinylpyrrolidone / vinylimidazole polymers, such. As Luviquat ^® (BASF), condensation products of polyglycols and amines, quaternized collagen polypeptides such as, for example, Lauryldimonium Hydroxypropyl Hydrolyzed Collagen (Lamequat® ^® L / Grunau), quaternized wheat polypeptides, polyethyleneimine, cationic silicone polymers such. As amodimethicones, copolymers of adipic acid and Dimethylaminohydroxypropyldiethylentriamin (Cartaretine ^® / Sandoz), copolymers of acrylic acid with dimethyldiallyl ammonium chloride (Merquat ^® 550 / Chemviron), polyaminopolyamides and their crosslinked water-soluble polymers, cationic chitin derivatives such as qua terniertes chitosan, optionally microcrystalline distributed, condensation products Dihaloalkylene, such as. B. dibromobutane with bis-dialkylamines, such as. B. bis-dimethylamino-1,3-propane, cationic guar gum, such as. ^Jaguar® CBS, ^Jaguar® C-17, ^Jaguar® C-16 from Celanese, quaternized ammonium salt polymers, e.g. B. Mirapol ^® A-15, Mirapol ^® AD-1, Mirapol ^® AZ-1 from Miranol.

Preferably, chitosan is used as the encapsulating material. Chitosans are biopolymers and are counted among the group of hydrocolloids. Chemically, they are partially deacetylated chitins of different molecular weight containing the following - idealized - monomer unit:

Unlike most hydrocolloids, which are negatively charged at biological pH levels, chitosans are cationic biopolymers under these conditions. The positively charged chitosans can interact with oppositely charged surfaces and are therefore used in cosmetic hair and body care products as well as pharmaceuticals Preparations used. For the production of chitosans is based on chitin, preferably the shell remains of crustaceans, which are available as cheap raw materials in large quantities. The chitin is thereby in a procedure, the first of Hackmann et al. has been described, usually initially deproteinized by the addition of bases, demineralized by the addition of mineral acids and finally deacetylated by the addition of strong bases, wherein the molecular weights may be distributed over a broad spectrum. Preference is given to using those types having an average molecular weight of 10,000 to 500,000 or 800,000 to 1,200,000 daltons and / or a Brookfield viscosity (1% strength by weight in glycolic acid) below 5000 mPas, a degree of deacetylation in the range from 80 to 88% and having an ash content of less than 0.3% by weight. For reasons of better solubility in water, the chitosans are generally used in the form of their salts, preferably as glycolates.

Anionic polymers. The anionic polymers have the task of forming membranes with the chitosans by coacervation. Salts of alginic acid are preferably suitable for this purpose. Alginic acid is a mixture of carboxyl-containing polysaccharides with the following idealized monomer unit:

The average molecular weight of the alginic acids or Alginates range from 150,000 to 250,000. There are as salts of alginic acid both their complete as well as their partial neutralization products, in particular the alkali metal salts and below this preferably the sodium alginate ("Algin") and the ammonium and alkaline earth salts. particularly preferred are mixed alginates, such as. Sodium / magnesium or sodium / calcium alginates. In an alternative embodiment However, the invention also anionic for this purpose come Chitosan derivatives, such as. B. Carboxylation and especially Succinylierungsprodukte in question. Alternatively, poly (meth) acrylates come with average Molecular weights in the range of 5,000 to 50,000 daltons as well the various carboxymethylcelluloses in question. Instead of anionic polymers can be used for training the envelope membrane also anionic surfactants or low molecular weight inorganic salts such as pyrophosphates used become.

As far as oil body or emulsifiers are used the same substances already described in detail above have been made, so that a repetition is unnecessary.

Production via coacervation. For the preparation of the microcapsules is usually prepared from 1 to 10, preferably 2 to 5 wt .-% aqueous solution of the gelling agent, preferably the agar agar ago and heated them under reflux. In the boiling heat, preferably at 80 to 100 ° C, a second aqueous solution is added, which contains the cationic polymer, preferably the chitosan in amounts of 0.1 to 2, preferably 0.25 to 0.5 wt .-% and the active ingredients in amounts of 0.1 to 25 and in particular 0.25 to 10 wt .-%; this mixture is called a matrix. The loading of the microcapsules with active ingredients can therefore also amount to 0.1 to 25% by weight, based on the capsule weight. If desired, you can Water-insoluble constituents, for example inorganic pigments, are added at this time to adjust the viscosity, these being added as a rule in the form of aqueous or aqueous / alcoholic dispersions. To emulsify or disperse the active ingredients, it may also be useful to add emulsifiers and / or solubilizers to the matrix. After the preparation of the matrix of gelling agent, cationic polymer and active ingredients, the matrix can optionally be very finely dispersed in an oil phase under high shear in order to produce the smallest possible particles in the subsequent encapsulation. It has proved to be particularly advantageous to heat the matrix to temperatures in the range of 40 to 60 ° C, while the oil phase is cooled to 10 to 20 ° C. In the last, now again obligatory step, the actual encapsulation takes place, ie the formation of the enveloping membrane by contacting the cationic polymer in the matrix with the anionic polymers. For this purpose, it is recommended that the optionally dispersed in the oil phase matrix at a temperature in the range of 40 to 100, preferably 50 to 60 ° C with an aqueous, about 1 to 50 and preferably 10 to 15 wt .-% aqueous solution of the anion polymer to treat and, if necessary, at the same time or subsequently to remove the oil phase. The resulting aqueous preparations generally have a microcapsule content in the range of 1 to 10 wt .-%. In some cases, it may be advantageous if the solution of the polymers contains other ingredients, such as emulsifiers or preservatives. After filtration, microcapsules are obtained, which on average have a diameter in the range of preferably about 0.01 to 1 mm. It is recommended to sift the capsules to ensure the most even size distribution possible. The microcapsules thus obtained may have any shape in the production-related framework, but they are preferably approximately spherical. Alternatively, one can also use the anionic polymers for the preparation of the matrix and perform the encapsulation with the cationic polymers, especially the chitosans. Alternatively, the encapsulation may also be effected using only cation polymers, use being made of their capacity to Choose to coagulate -value at pH values above the _pKa. The capsules can then be crosslinked using glutaraldehyde, for example; the crosslinking is also enzymatically possible.

Production over Emulsion process. In a second alternative method is for the preparation of the microcapsules according to the invention First, an O / W emulsion is prepared, which in addition the oil body, water and the active ingredients contains effective amount of emulsifier. For the preparation of the matrix This preparation is mixed with vigorous stirring with a suitable Amount of an aqueous Anionpolymerlösung added. Membrane formation occurs by adding the cationic polymer solution. The entire process preferably takes place in the weakly acidic region at pH = 3 to 4 instead. If necessary, the pH is adjusted by Addition of mineral acid. After membrane formation, the pH is raised to 5 to 6, for example by adding triethanolamine or another base. This leads to an increase in the viscosity, by adding further thickeners, such as. B. polysaccharides, especially xanthan gum, guar guar, agar, alginates and tyloses, Carboxymethylcellulose and hydroxyethylcellulose, higher molecular weight Polyethylene glycol mono- and diesters of fatty acids, polyacrylates, Polyacrylamides and the like are still supported can. Finally, the microcapsules of the aqueous Phase for example by decantation, filtration or centrifugation separated. Provided the production of the capsules over the Crosslinking of emulsions with urea or melamine-formaldehyde resins PVM / MA polymers are the preferred polymers.

Production via layer-by-layer method. In a third alternative method, the formation of the microcapsules is carried out around a preferably solid, for example, crystalline core by coating it in layers with oppositely charged polyelectrolytes. In this connection, see the European patent EP 1064088 B1 (Max Planck Society).

The mechanical pumping devices

As explained above, there is the preferred embodiment the present technical teaching therein, a pressure-resistant bag to insert into an outer container, the gap between two containers with about 3 bar to apply and then pour the preparations into the bag against this pressure. Upon actuation of the spray device is then the preparation automatically released as a fine spray or as an aerosol.

However, other options may be considered for the type of release. An alternative is not to pressurize the space between the inner and outer container from the outside. Instead, it is sufficient to firmly enclose the bag with a cuff made of an elastic material, preferably with a rubber cuff. When filling the inner container with the preparation of active ingredient, the bag is forcibly stretched, which takes place against the pressure of the cuff and a counter pressure, which is also in the order of 2 to 3 bar, without it being necessary to submit a back pressure from outside before filling.

It is of course also possible to work with containers that are filled without pressure. In these cases, sprayers are used in which a reciprocating piston is integrated or with this directly are connected. By repeated actuation of the pumping device Mechanical pressure is generated and the active ingredient is sprayed. The advantage here is that the containers easily refill leave and no aerosols are generated. Because the systems are completely can be stored without risk, they can also be stored safely and be handled. The disadvantage, however, is that for application a sufficient amount of active ingredient numerous pumping operations are required and not sprayed over the head can be. However, such systems provide for it also very inexpensive alternatives. Corresponding Products are for example from the company Airspray International B. V. commercially available.
