Abstract: Provided is a detergent and conditioning cosmetic composition for keratin fibers, comprising, in a cosmetically acceptable medium: (i) at least one organosilicon compound chosen from silanes comprising one silicon atom and siloxanes comprising two or three silicon atoms, wherein the at least one organosilicon compound also comprises at least one basic chemical functional group and at least one group chosen from hydroxyl and hydrolysable groups per molecule, wherein the at least one organosilicon compound is present in a total amount ranging from 0.01% to 5% by weight, relative to the total weight of the cosmetic composition; (ii) at least one anionic surfactant, and iii) at least one nonionic thickener, wherein the weight ratio of the at least one organosilicon compound to the at least one anionic surfactant is equal to or greater than 5×10?4:1. Also provided herein is a process involving said compositions.

Abstract: Provided herein is a cosmetic composition for washing and conditioning keratin fibers, comprising, in a cosmetically acceptable medium: (i) at least one organosilicon compound chosen from silanes comprising one silicon atom and siloxanes comprising two or three silicon atoms, wherein the at least one organosilicon compound also comprises at least one basic chemical functional group and at least one group chosen from hydroxyl and hydrolysable groups per molecule; (ii) at least one anionic surfactant chosen from sulfate and sulfonate anionic surfactants; (iii) at least one carboxylic anionic surfactant other than the at least one anionic surfactant of (ii) chosen from alkyl ether carboxylic acids and salts thereof, and (iv) at least one amphoteric surfactant. Also provided is a cosmetic process for treating keratin fibers, comprising applying the cosmetic composition to the keratin fibers.

Abstract: The present disclosure relates to cosmetic compositions for washing and conditioning keratin fibers, such as human keratin fibers, for example, the hair, comprising in a cosmetically acceptable medium: i) at least one organic silicon compound chosen from silanes comprising one silicon atom and siloxanes comprising two or three silicon atoms, said organic silicon compounds having at least one basic chemical functional group and at least one group chosen from hydroxyl groups and hydrolysable groups per molecule; ii) at least one anionic surfactant; and iii) at least one aminated silicone not having a quaternary ammonium group different from the at least one organic silicon compound of part i). The present disclosure also relates to a method of cosmetic treatment of keratin fibers as well as a use employing a cosmetic composition according to the disclosure.
