Abstract:
A cosmetic or dermatological composition, comprising: an aqueous phase dispersed in an oily phase with a silicone emulsifying agent, wherein the viscosity of the composition, measured with a Rheomat 180 viscometer at a shear rate of 200 s−1 and at 25° C., ranges from 3 Pa.s (30 poises) to 20 Pa.s (200 poises), the aqueous phase constituting at least 78% by weight with respect to the total weight of the composition with the water of the aqueous phase constituting at least 65% of the total weight of the composition, and the emulsifying agent consisting of the dimethicone copolyol of formula (I): wherein R1 is
Abstract:
A stable composition for topical application is provided which contains at least one enzyme, at least one polyol, the latter being present in a quantity which is effective for obtaining a water activity value of the composition of less than or equal to 0.85, and at least one structuring agent chosen from polymers and oils, for the purpose of stabilizing the enzyme. In such a composition, the enzyme retains its efficacy over time. The composition obtained can be used for cleansing and/or caring for and/or protecting the skin and/or keratinous fibers.
Abstract:
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.

Abstract:
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.
Abstract:
The present invention provides non-invasive, in vivo, DISC-type methods of evaluating structural changes in skin due to a variety of exogenous or endogenous factors. It is possible to develop quantitative and qualitative characterizations of skin. For example, the skin may be characterized based on its structural age rather than its chronological age. Based on the structural age and type of an individual's skin, cosmetic, dermatologic, medicinal or manipulative treatment may be customized. The method is based, in part, on quantification of discontinuities that arise in the skin during normal facial expression. The methods provide for evaluating changes in human skin response that occur over a short term (one day) or long term (one or more years). The methods provide for evaluating the skin's response to cosmetic, dermatologic or medicinal treatment or to any other factor alleged to affect the skin.
Abstract:
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.
Abstract:
The present provides a composition that includes, in a physiologically acceptable medium: an aqueous phase dispersed in an oily phase with a silicone emulsifier; wherein the aqueous phase represents at least 80% by weight relative to the total weight of the composition; wherein the silicone emulsifier is an alkyldimethicone copolyol comprising an HLB of less than 8; and wherein a weight ratio of the oily phase to the silicone emulsifier is greater than or equal to 5. The present invention also provides a cosmetic, which includes the above-mentioned composition and methods of using the above-mentioned composition for treating, protecting, caring for, or removing make-up from the skin, lips or hair, cleansing the skin, lips or hair, and making up the skin or lips, treating, protecting, and caring for the scalp, and treating greasy skin. The composition can be used in particular in cosmetics and/or dermatology.
Abstract:
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.
Abstract:
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.
