The present invention relates to an in particular cosmetic or dermatological composition comprising, in a physiologically acceptable support: a) at least one merocyanine of formula (1) or (2), b) at least one oily phase comprising at least one isosorbide ether. The present invention also relates to a non-therapeutic cosmetic process for caring for and/or making up a keratin material, comprising the application, to the surface of the said keratin material, of at least one composition as defined above. The invention also relates to a non-therapeutic cosmetic process for limiting the darkening of the skin and/or improving the colour and/or uniformity of the complexion, comprising the application, to the surface of the keratin material, of at least one composition as defined previously. The invention also relates to a non-therapeutic cosmetic process for preventing and/or treating the signs of ageing of a keratin material, comprising the application, to the surface of the keratin material, of at least one composition as defined previously. ##STR00001##

The invention relates to a composition comprising: A) at least one non-silicone-containing quaternary ammonium compound, B) at least one cosmetic oil, C) at least one nonionic surfactant, D) at least one nonaqueous solvent, E) water.

The instant disclosure relates to anhydrous hair-treatment compositions. The anhydrous hair-treatment compositions typically include one or more bis-urea derivatives, hydrophobic silica aerogel, and one or more solvents, for example, ester oils and non-ester oil solvents. Additional components such as silicones, etc., can also be included. Kits comprising the hair-treatment compositions and methods of using the hair-treatment compositions are also disclosed.

Compositions, kits, and methods for repairing bonds, for example, disulfide bonds, in hair or on the skin are disclosed. The compositions provide improved conditioning benefit for dry hair or moisturize the skin. The compositions also provide a long lasting moisturized feel and smooth feel to the skin or hair, without feeling greasy. The compositions contain one or more compounds that covalently bind at least two thiol groups in the hair or on the skin. Use of the binding compositions prevents reversion of the repaired bonds to their free thiol state, for at least one week or one month, or more, after a single application of the composition. Improved methods of styling hair, for example permanent hair waving, hair curling, hair coloring or highlighting, and hair straightening, are also provided.
