A water-in-oil emulsion containing ascorbic acid and, as an emulsifier, a dimethiconecopolyol or an alkyldimethiconecopolyol, where the aqueous phase having a pH ranging from 5.5 to 7.5. This emulsion allows ascorbic acid to be stabilized and can be used, in particular, in the cosmetics and/or dermatological fields. The invention also relates to a cosmetic process for treating the skin using the emulsion.

Emulsion containing ascorbic acid and its uses in the cosmetics and dermatological fields

The invention relates to a solid composition in the form of a water-in-oil emulsion. The aqueous phase represents at least 70% by weight with respect to the total weight of the composition. The composition contains at least one silicone emulsifier and at least 3% by weight of at least one wax with respect to the total weight of the composition.

Solid composition and its uses, in particular its cosmetic uses

The invention relates to a composition containing fibers and a copolymer comprising carboxylate groups and polydimethylsiloxane groups. The composition according to the invention may especially constitute a care or make-up composition for keratin materials such as the skin, including the scalp, the lips of the face and integuments, for instance the eyelashes, the eyebrows, the nails and the hair. The invention also relates to the use of a copolymer comprising carboxylate groups and polydimethylsiloxane groups in a composition containing fibers to ensure a homogeneous dispersion of the fibers in the composition and to stabilize the composition.

Composition containing fibers and a dispersing copolymer

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.

Composition in the form of a water-in-oil emulsion containing fibers, and cosmetic use thereof

Composition in the form of a water-in-oil emulsion having an evolutive shear rate

Water-in-oil emulsion containing fibers and the use thereof as a cosmetic composition

A composition in the form of an oil-in-water emulsion comprising, in a physiologically acceptable medium, an oily phase dispersed in an aqueous phase, characterized in that it contains fibers and a surfactant system comprising at least one glyceryl ester of a C -C fatty acid and at least one polyethylene glycol ester of a C -C fatty acid. 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.

Composition in the form of an oil-in-water emulsion containing fibers and uses thereof

Composition in the form of a water-in-oil emulsion having a changing shear rate

The present invention relates to the use of a silicone gum to stabilize ascorbic acid or one of its esters or salts in a topical composition and to novel compositions comprising these components and having a pH of from 4 to 7. These compositions can be used in the fields of cosmetology, dermatology and veterinary medicine.

Use of a silicone gum to stabilize ascorbic acid, and novel compositions comprising these components

A water-in-oil emulsion containing ascorbic acid and, as an emulsifier, a dimethiconecopolyol or an alkyldimethiconecopolyol, where the aqueous phase having a pH ranging from 6.1 to 7.5. This emulsion allows ascorbic acid to be stabilized and can be used, in particular, in the cosmetics and/or dermatological fields. The invention also relates to a cosmetic process for treating the skin using the emulsion.

A composition in the form of a water/oil/water triple emulsion comprising an outer aqueous phase and an oily phase constituting, with an inner aqueous phase, a W/O primary emulsion, the outer aqueous phase comprising, in combination, an emulsifying copolymer of carboxylic acid with a fatty chain, and a crosslinked poly(acrylamidomethylpropane-sulfonic acid). The emulsion remains stable, even in the presence of an acidic active agent, and is particularly appropriate as vehicle for water-sensitive and/or oxygen-sensitive active agents, in particular in a cosmetic or dermatological composition. The active agent can be, in particular, a vitamin, such as ascorbic acid or retinol, an enzyme and an .alpha.- or .beta.-hydroxy acid. The emulsion obtained can constitute, in particular, a composition for cleaning and/or treating and/or protecting the skin and/or mucous membranes and/or keratinous fibers.

Stable W/O/W emulsion and its use as cosmetic and/or dermatological

A synegistic system based on a phosphonic acid derivative and on a metabisulphite, for stabilizing ascorbic acid. The invention also relates to compositions, in particular cosmetic and dermatological compositions, containing ascorbic acid and this stabilizing system, and to the use of these compositions in the cosmetics and/or dermatological fields.

System for stabilizing ascorbic acid based on a phosphonic acid

A cosmetic or dermatological composition is described that includes, as moisturizing agent, a polydimethylsiloxane containing glucoside groups of formula (I): ##STR1## The composition has long-lasting skin moisturization properties. A method is also described for moisturizing the skin and for treating dry skin.

Use of a polydimethylsiloxane containing glucoside groups as a

An emulsion comprising an oily phase dispersed in an aqueous phase with the aid of a silicone emulsifying agent, the oily phase comprising at least 50% by weight of silicone oil and the aqueous phase containing at least one polyol in a quantity which imparts a water activity value to the emulsion of .ltoreq.0.85.
