Abstract: The invention relates to compositions, in particular cosmetic compositions, in particular cosmetic hair compositions, comprising anionic surfactants, organosilanes and particular amino silicones, comprising at least one polyoxyalkylenated group and/or at least one quaternary ammonium group. The invention also relates to a cosmetic process for treating, and more particularly for washing and/or conditioning, the hair, using said composition.

Abstract: The present invention relates to compositions for conditioning hair fibers, in particular human hair fibers, comprising (a) cationic surfactants; (b) thiol-based compounds; (c) fatty alcohols in an amount of from about 6% to about 20% by weight; (d) a component selected from polyols, fatty substances other than a fatty alcohol, and mixtures thereof; (e) water; and (f) optionally, neutralizing agents, wherein the pH of the composition ranges from 2 to less than 7. The invention also concerns a process for imparting hair care benefits to hair fibers such as straightening effects, volume reduction, fizz control, manageability, cosmeticity, and smooth feel, in addition to conditioning benefits and a use for hair care employing the cosmetic compositions of the present invention.

Abstract: The present invention relates to a cosmetic composition, especially a haircare composition for conditioning the hair, which comprises an amino silicone, a cationic surfactant, a fatty alcohol comprising 8 to 30 carbon atoms, and a hydrocarbon-based oil. The invention also relates to a treatment process for keratin substances, in particular for conditioning hair, implementing said cosmetic composition.

Abstract: The present invention relates to a cosmetic composition which is preferentially anhydrous, comprising from 10% to 40% by weight of liquid fatty esters, at least 30% by weight of volatile oils other than the liquid fatty esters, and thickeners. The composition may also comprise particles that are insoluble in the medium, such as pigments or microcapsules. The invention also relates to a cosmetic treatment process, especially for caring for or conditioning the hair, using this composition, which is more particularly intended for curly or frizzy hair.
