Abstract

Cosmetic compositions which on standing form two or more distinctive layers, but which when shaken provide an emulsion which remains homogeneous for a period of at least 30 seconds comprise i) an aqueous phase; ii) an oil phase containing a volatile silicone; and iii) an emulsifying agent. The volatile silicone may be a dimethicone fluid or a cyclomethicone fluid. The emulsifying agent may be a dimethicone copolyol.

Description

Cosmetic Composition This invention relates to cosmetic compositions.
According to the present invention there are provided cosmetic compositions which on standing form two or more distinctive layers, but which when shaken provide an emulsion which remains homogeneous for a period of at least 30 seconds. The cosmetic compositions of the present invention comprise; i) an aqueous phase; ii) an oil phase containing a volatile silicone; and iii) an emulsifying agent.
The aqueous phase may contain between 10% and 80, by weight water and may contain up to 40% by weight of a water-miscible liquid for eam?'e, glycerin, propylene glycol, butylene glycol, sorbitol or sodium pyrrolidone carboxylate or mixtures thereof.
Advantageously, the compositions may contain up to 20% by weight of glycerin or up to 15% by weight of sodium pyrrolidone carboxy-'ate. vEt aque^"C phase may also contain other water soluble ingredients such as dyes, preservatives, humectants, moisturisers, sun screens, herbal extracts, thickeners, conditioners, vitamins or minerais. I;hen the cosmetic compositions are to be used as cleansing solutions, the aqueous phase may comprise up to 30% by weight of a water soluble alcohol, for example ethanol or isopropanol, which enhance the cleansing properties of the compositions.
Thc Oil phase may constitute between 1 and 60% by weight of the cosmetic compositions of the present invention. Advantageously the oil-phase comprises one or more volatile silicones and makes up between 30 and 50% by weight of the cosmetic compositions. Preferred volatile silicones include the volatile dimethicone fluids for example, hexamethyldisiloxane or volatile cyclomethicone fluids, for example, octamethylcyclotetrasiloxane or decamethylcyclopentasiloxane.
Suitable dimethicones are available from commercial sources such as Dow Corning (as 200 Fluid), Union Carbide (as L-45), TH. Goldschmidt AG (as the ABIL 10 to ABIL 10,000 range) and Wacker-Chemie GmbH (as the AK range of Silicone Fluids). Suitable cyclomethicones are available from commercial sources, such as Dow Corning (as 344 Fluid or 345 Fluid), Union Carbide (as VS-7207, VS-7158 or VS-7249), TH. Goldschmidt AG (as ABIL K4 or B8839) or Wacker-Chemie GmbH (as Silicones fluids ZC2C, 225, Z030 and Z040) Up to 20% by weight of other materials which are soluble or dispersible in the volatile silicone may be included in the oil phase of the compositions.Examples of suitable compatible components include natural or synthetic oiis such as camellia oil, wheatgerm oil, sesame oil, avocado oil, almond oil, cetearyl isononanoate or antioxidants, sun screens, fats cr waxes, resins, fragrance compounds and dyes.
The emulsifying agent may comprise between 0.05% and 30% by weight of the cosmetic composition according to the present invention. In preferred compositions the emulsifying agent comprises between 2 and 10% by weight of the composition. The emulsifying agent may be a single component or it may -be a mixture of a primary emulsifier and a co-emulsifier.Particularly preferred emulsifying agents are the dimethicone copolyols of formula I:
in which R1, R2 and R3, which may be the same or different, are alkyl groups of 1 to 3 carbon atoms, for example methyl or ethyl groups; in which A represents a dialkylsiloxy group of formula II:
in which R4 and R5 which may be the same or different are 11 groups containing 1 to 4 carbon atoms; in which B represents a polyoxyalkylene-containing di-substituted siloxy unit of formula III:
in which R6 is an alkyl group containing 1 to 4 carbon atoms, a is 0 or a number from 1 to 8, b is 2 or 3, c is a number from 3 to 20 and R7 is a terminal group selected from H, alkyl, aryl and acyl groups; in which n is a number from 5 to 100; and in which m is a number from 1 to 16.
In particularly preferred emulsifying agents of formula I, the groups R1 R2, R3, R4, R5, R6 and R7 are methyl groups and a is 3 or 4, b is 2, c is a number from 5 to 12, n is a number from 15 to 30 and m is a number from 1 to 5. In especially preferred emulsifying agents of formula I R1, R2, R3, R4, R5, R6 and R7 are methyl, a is 3, b is 2, c is 7.5, n is 20 and m is 3.2.
Suitable dimethicone copolyols are available from commercial sources such as Dow Corning (as 190 or 193 surfactant), Union Carbide (as Silwet Surface Active Copolymers), TN. Goldschmidt AG (as ABIL 8842, 8843, 8851, 8852, 8863, 8873) or Wacker-Chemie GmbH (as Silicone Fluids VP 1661 and VP 1629). A blend of suitable dimethicone copolyols and cyclomethicones suitable tot use of the volatiLe silze component in the compositions of the present invention are commercially available from Union Carbide (as Silsoft Beauty Aid).
The cosmetic compositions of the present invention may be used for any of the known cosmetic products.
One group of particularly preferred cosmetic compositions are those which are used for cleansing the skin. These particularly preferred cleansing compositions contain a water-soluble alcohol which enables solubilisation of sebum and other lipidic compounds which are present on the skin surface. Such a product is normally applied to the skin surface with the aid of an absorbent material such as cotton wool, onto which the sebum and other lipidic materials are deposited. When applied in this way to the skin the cosmetic composition I deposited on the skin. After evaporation of the volatile silicone, the alcohol and the water a deposit of the non-volatile components will be left.This is particularly advantageous if the non-volatile component remaining on the skin is a humectant or other ingredient imparting beneficial effects on the skin.
The use of compositions in the form of two or more phases shows many advantages over single phase cosmetic compositions. By use of the present invention it is possible to minimise the quantity of emulsifier necessary to present a satisfactory emulsion to the user. It is well known that emulsifiers can show adverse reactions on the skin due to the reduction in surface tension and subsequent absorbtion of these materials. The present invention enables the minimum anoint cf emulsifier to be used but allows a satisfactory emulsion to be formed at the time of use.
By use of the present invention it is possible to have in the same compositions a water-soluble component and an oil soluble component which are known to be incompatible on prolonged storage. Before use the cosmetic composittor.s will be agitated so that an emulsion is formed but when the product is allowed to stand the phases will separate out so that there is no contact between the incompatible components n the aqueous and the oil phase. The compositions of the present invention can be used as a delivery system of skin beneficial ingredients particularly where a user is sensitive to traditional cosmetic products. By the appropriate use of water-soluble colouring materials in the aqueous phase and oil soluble colouring materials in the oil phase it is possible to provide a product which is aesthetically pleasing and which has great appeal to the user of the cosmetic compositions. It has been wound Dy the present applicant that the compositions of the present invention require substantially smaller amounts of preservative than has been usual in cosmetic compositions heretofore. In the Examples given herein no preservatives have been found to be necessary.
