Stable water-in-oil emulsion for cosmetic or pharmaceutical use. This emulsion comprises a fatty phase in a proportion of 15 to 40% consisting of at least one silicone in a proportion of 15 to 40% by weight relative to the total weight of the emulsion, and an aqueous phase containing at least one electrolyte-insensitive aqueous gelling agent, the emulsifying agent of the said emulsion being an alkyl- or alkoxydimethicone copolyol of general formula: ##STR1## in which: X is a hydrogen atom or a C.sub.1 -C.sub.16 alkyl, C.sub.1 -C.sub.16 alkoxy or C.sub.1 -C.sub.16 acyl, Y is a C.sub.8 -C.sub.22 alkyl or C.sub.8 -C.sub.22 alkoxy radical, n=0 to 200, m=1 to 40, q=1 to 100, the molecular weight of the residue (C.sub.2 H.sub.4 O--).sub.x (C.sub.3 H.sub.6 O--).sub.y --X being from 250 to 2000, and x and y being chosen in such a way that the weight ratio of oxyethylene to oxypropylene groups is between 100:0 and 20:80. Production of stable emulsions having excellent cosmetic properties.
This is a Continuation-in-Part of prior Application Ser. No. 585,869 filed Jan. 16, 1996 now abandoned which is a Rule 60 Continuation of Application Ser. No. 08/122,420, filed Jan. 7, 1994 now abandoned.
An emulsion makeup composition comprising: (a) a water phase having solubilized therein an effective amount of soy protein capable of forming a skin firming and toning film on the skin; (b) an oil phase comprising silicone oil having dispersed therein one or more colorants, said silicone oil phase capable of plasticizing the film formed on the skin by the solubilized soy protein in the water phase; and (c) an effective amount of a surfactant capable of causing the water and oil phase to form an emulsion which maintains stability at 50.degree. C. for two weeks.
The present invention relates to a composition in the form of a cream composed of a water-in-oil emulsion, wherein it includes at least 25% by weight of an aqueous phase with respect to the total weight of the composition, at least one silicone emulsifier and at least 5% by weight of one or more waxes with respect to the total weight of the composition. The present invention also relates to the uses of the above composition in the cosmetics and dermatological fields, in particular in caring for, treating and/or making up the skin and/or mucous membranes and more particularly in treating wrinkles and/or fine lines of the skin and/or in treating dry skin. The invention also relates to a process for the preparation of the above composition, wherein at least one stage of the process is carried out using a mixer-extruder.
A composition in the form of a water-in-oil emulsion containing fibers, at least one silicone surfactant and at least one clay. The composition may be used, for example, for caring for, treating, making up or cleansing the skin, the lips, the eyelashes and/or the hair.
A composition in the form of a water-in-oil emulsion containing fibers, at least one silicone surfactant and-at least one wax. The composition obtained has very good stability and can in particular constitute a cosmetic composition. The invention also relates to the use of the said composition, in particular for caring for, treating, making up or cleansing the skin the lips, the eyelashes and/or the hair.
