Abstract
A skin treatment composition is provided which includes a crosslinked non- emulsifying siloxane elastomer, a skin conditioning agent, a volatile siloxane and no more than 5 % water. Hydrocarbons such as petrolatum and polyols such as glycerin are the preferred skin conditioning agents. Inclusion of the elastomer provides a non-traditional smooth/silky feel to the skin upon application with a non-draggy rub in.
Description
BACKGROUND OF THE INVENTION
Meld of the Invention The invention relates to anhydrous cosmetic compositions for topical application to the skin whose properties are enhanced by incorporation of certain elastomeric silicones.
The Related Art Emollients including organic esters and hydrocarbons, especially petrolatum, have long been used medicinally as skin conditioning agents. These substances are second only to water as moisturizing ingredients of choice. They function primarily as an occlusive barrier. The water content of the outer layers of human skin stratum corneum is a controlling factor in the appearance of dry skin symptoms. When the stratum corneum contains an adequate amount of water within the range of ten to twenty percent, the skin remains flexible. However, when the water content falls below ten percent the stratum corneum often becomes brittle and rough and can exhibit scaling and cracking.
The stratum corneum receives its water from the deep layers of the epidermis by diffusion or when it is brought into direct contact with water. The diffusion process is controlled by the water content of the skin as well as the concentration gradient. In a very dry environment, the water loss from the external skin layers can be significant and often exceeds the rate of replacement by diffusion. An occlusive or semi-occlusive barrier substance placed on the surface of the skin acts to retard water loss to the environment. It also allows the skin surface to rehydrate via a diffusion mechanism.
While there are many effective and economical skin conditioning agents, they nevertheless suffer from certain disadvantages.
Often the emollient types are delivered as water in oil emulsions. It is difficult to attain the critical formula balance between oil and water phases to an extent sufficient to ensure long term storage stability. One part of this critical balance is the internal phase volume. A critical volume must be obtained to maximize the chemical and physical interactions which produce and stabilize the system. If this critical volume is not balanced properly the product may suffer from viscosity change and eventual phase separation. Usually the optimum volume is quite large which limits the external phase volume size, and gives the system a draggy unfavorable slow break attribute. This critical internal phase volume restriction can reduce functionality and add unfavorable feel characteristics.
Anhydrous systems avoid emulsion stability problems.
Unfortunately other aesthetic issues arise with anhydrous systems. Not all oily phase materials are compatible at high concentration. Moreover, occlusive agents such as petrolatum are relatively greasy. They suffer the disadvantage of transfer onto clothing and are not easily removed from the skin by washing with soap. Neither do they allow for adequate penetration into the epidermis.

U.S. Patent 5,387,417 (Rentsch) reports obtaining cosmetically acceptable, translucent moisturizing lotions through emulsification of a petrolatum base with a crosslinked organopolysiloxane-polyoxyalkylene emulsifier.
According to the disclosure, not only is compatibility achieved but this siloxane allows for matching of refractive indices for the continuous and discontinuous phases.
U.S. Patent 5,280,019 (Klimisch) reports compositions which enhance the absorption and retention of moisturizer on the skin. These results are achieved through use of an organosilicon compound which is a carboxy functionalized polysiloxane or its metal carboxylate salt.
EP 0295 886 (Harashima et al) discloses a facial cleanser incorporating particles of organopolysiloxane elastomer.
These systems utilize water as the essential carrier rather than any volatile siloxane. JP 07 267 820 (Takahashi et al) as reported by Chemical Abstracts, Vol. 124(4), No. 37399 discloses two-layer oily make-up cosmetics containing organopolysiloxane elastomer particles and hydrophobic-treated powders. Hydrophilic functional ingredients, such as glycerin, necessary to improve skin moisturization, are not described in this publication.
Evident from the foregoing art is that certain types of polysiloxanes incorporating hydrophilic functionality, e.g.
polyoxyalkylene or carboxylate units, can assist in the emulsification of oily phases. Indeed these disclosures ' suggest the requirement for hydrophilic functionality on the silicones. Incorporation of hydrophilic groups for emulsification unfortunately detracts from the ability of silicones to provide a soft, silky afterfeel. These prior AN~fn sH~
76356 (C) wo - 3a -art hydrophilic silicones also do not fully solve oil and water phase compatibility problems. New systems are needed to carry relatively high levels of aqueous based moisturizing ingredients (e. g. glycerin). Also necessary are silicones that can achieve a smoother emulsion break to maximize positive sensozy/feel attributes when the emulsions are rubbed into the skin. Anhydrous systems of occlusives are also not benefitted from hydrophilic bearing silicones which often lead to phase separation.

Accordingly, it is an object of the present invention to provide a skin treatment composition which is anhydrous yet provides improved skinfeel properties.
Another object of the present invention is to provide a skin treatment composition which has stability against phase separation even under freeze/thaw cycling.
Still another object of the present invention is to provide a skin treatment composition which achieves a smooth non-draggy rub-in upon initial application to the skin.
These and other objects of the present invention will become more readily apparent from consideration of the following summary and detailed description.
~MMARY OF THE INVENTION
A skin treatment composition is provided which includes:
(i) from 0.1 to 300 of a crosslinked non-emulsifying siloxane elastomer;
(ii) from 1 to 50% of a skin conditioning agent;
(iii)from 10 to 800 of a volatile siloxane; and (iv) from 0 to 5~ of water.
Particularly preferred conditioning agents within the context of this invention are hydrocarbons such as petrolatum and moisturizing polyols such as glycerin.
Cyclomethicones are the preferred volatile siloxanes.
Elastomers of the present invention are preferably formed _ 5 _ _ from divinyl compounds, particularly siloxane polymers with at least two free vinyl groups, reacting with Si-H
linkages on a polysiloxane backbone. Most preferred of the elastomers are dimethyl polysiloxanes crosslinked by Si-H sites on a molecularly spherical MQ resin.
The composition of the present invention is based upon the concept of using crosslinked non-emulsifying siloxane elastomer in combination with skin conditioning agents of 20 a sticky nature. Although we do not wish to be bound by theory, we believe these conditioning agents (when hydrophilic) are delivered in an internal phase of the mixture of elastomer and volatile siloxane. The latter acts as the external phase while dispersing an otherwise insoluble crosslinked siloxane elastomeric powder. Upon application of this system to the skin, the volatile siloxane evaporates leaving behind functional materials more compatible with skin fluids which become entrapped in the upper layer of the stratum corneum. Siloxane elastomer, not being compatible with these body fluids, remains on the surface of the skin. Since this elastomer is completely dispersed in the volatile siloxane, it is deposited in a very uniform layer on the skin. The thick three-dimentionally crosslinked siloxane elastomer film now functions as a layer between the insoluble aqueous/lipid context of the skin and the external environment. This mechanism masks negative feel characteristics of high levels of hydrophilic functional ingredients, such as glycerin.
DETAILED DESCRIPTION OF THE INVENTION
Now it has been found that crosslinked non-emulsifying siloxane elastomers in combination with skin conditioning agents and, volatile siloxane result in a highly stable J6356(C) w0 system and deliver an unusually soft, silky afterfeel to skin.
Crosslinked non-emulsifying siloxane elastomers are the first essential element of this invention. They will usually have an average number molecular weight in excess of 2,000, preferably in excess of 1,000,000. Typically they will range from 10,000 to 20 million. The term "non-emulsifying" defines a siloxane from which polyoxyalkylene units are absent. Advantageously the elastomers are formed from a divinyl compound, particularly a polymer with at least two free vinyl groups, reacting with Si-H linkages of a polysiloxane backbone such as a molecularly spherical MQ
resin. Suitable elastomer compositions are commercially available from the General Electric Company under product designation General Electric Silicone 1229 with proposed CTFA name of Cyclomethicone and Vinyl Dimethicone/Methicone Cross Polymer, delivered as 20-35~ elastomer in a cyclomethicone carrier. A related elastomer composition under the CTFA name of Crosslinked Stearyl Methyl Dimethyl Siloxane Copolymer is available as Gransil SR-CYC (25-350 elastomer in cyclomethicone) from Grant Industries, Inc., Elmwood Park, New Jersey. The commercial products from General Electric and Grant Industries preferably are further processed by subjecting them to a high pressure (approx-imately 5,000 psi) (where 1 psi = 6.8947 x 104 dynes/cm2) treatment in a Sonolator with recycling in 10 to 60 passes.
Sonolation achieves a resultant fluid with elastomer average particle size ranging from 0.2 to 10 micron, preferably 0!5 to 5 micron. Viscosity is best when ranging between 300 and 20,000 cps (0.3 and 20 Pa.s) at 25°C as measured by a Brookfield LV Viscometer (size 4 bar, 60 rpm, 15 sec.).
~~n ~~~,ccy _ 7 - _ Amounts of the elastomer may range from 0.1 to 30~, optimally from 1 to 15~, most preferably from 3 to 10~ by weight of the composition.
A second essential element of the present invention is that of a skin conditioning agent. These agents preferably are selected from humectants, exfoliants, emollients, and mixtures thereof.
Humectants usually are polyhydric alcohols intended for moisturizing, reducing scaling and stimulating removal of built-up scale from the skin. Typical polyhydric alcohols include polyalkylene glycols and more preferably alkylene polyols and their derivatives. Illustrative are propylene glycol, dipropylene glycol, polypropylene glycol, polyethylene glycol, sorbitol, hydroxypropyl sorbitol, hexylene glycol, 1,3-butylene glycol, 1,2,6-hexanetriol, ethoxylated glycerin, propoxylated glycerin and mixtures thereof. Most preferably the humectant is glycerin.
Amounts of humectant may range anywhere from 1 to 50~, preferably from 10 to 40%, optimally from 25 to 35% by weight.
Exfoliants according to the present invention are preferably selected from alpha-hydroxycarboxylic acids, beta-hydroxycarboxylic acids and salts of these acids.
The carboxylic acids preferably are CZ-C3~ carboxylic acids. Most preferred are glycolic, lactic and salicylic acids and their ammonium salts. Amounts of the exfoliants preferably range from 1 to 150, more preferably from 2 to 10o by weight.
A wide variety of C2-C3o alpha-hydroxycarboxylic acids may be employed. Suitable examples of which include:
-hydroxyethanoic acid -hydroxypropanoic acid -hydroxyhexanoic acid -hydroxyoctanoic acid -hydroxydecanoic acid -hydroxydodecanoic acid -hydroxytetradecanoic acid -hydroxyhexadecanoic acid -hydroxyoctadecanoic acid -hydroxyeicosanoic acid -hydroxydocosanoic acid -hydroxyhexacosanoic acid, and -hydroxyoctacosanoic acid When the conditioning agent is an emollient it is preferably be selected from hydrocarbons, fatty acids, fatty alcohols and esters. Petrolatum is the most preferred hydrocarbon type of emollient conditioning agent. Other hydrocarbons that may be employed include mineral oil, polyolefins such as polydecene, and parafins such as isohexadecane (e. g. Permethyl 99~ and Permethyl 101~).
Fatty acids and alcohols preferably have from 10 to 30 carbon atoms. Illustrative of this category are pelargonic, lauric, myristic, palmitic, stearic, isostearic, hydroxystearic, oleic, linoleic, ricinoleic, arachidic, behenic and erucic acids and alcohols.
Oily ester emollients preferably are those selected from one or more of the following classes:
1. Triglyceride esters such as vegetable and animal fats and oils. Examples include castor oil, cocoa butter, safflower oil, cottonseed oil, corn oil, olive oil, cod liver oil, almond oil, avocado oil, palm oil, sesame oil, squalene, Kikui oil and soybean oil.
2. Acetoglyceride esters, such as acetylated monoglycerides.
3. Ethoxylated glycerides, such as ethoxylated glyceryl monostearate.
4. Alkyl esters of fatty acids having 10 to 20 carbon atoms. Methyl, isopropyl, and butyl esters of fatty acids are useful herein. Examples include hexyl laurate, isohexyl laurate, isohexyl palmitate, isopropyl palmitate, decyl oleate, isodecyl oleate, hexadecyl stearate, decyl stearate, isopropyl isostearate, diisopropyl adipate, diisohexyl adipate, dihexyldecyl adipate, diisopropyl sebacate, lauryl lactate, myristyl lactate, and cetyl lactate.
5. Alkenyl esters of fatty acids having 10 to 20 carbon atoms. Examples thereof include oleyl myristate, oleyl stearate, and oleyl oleate.
5. Ether-esters such as fatty acid esters of ethoxylated fatty alcohols.
Another object of the present invention is to provide a skin treatment composition which has stability against phase separation even under freeze/thaw cycling.
Still another object of the present invention is to provide a skin treatment composition which achieves a smooth non-draggy rub-in upon initial application to the skin.
