US 2021/0275420 A1 · HAIR COSMETIC COMPOSITIONS CONTAINING THIOL-BASED COMPOUNDS AND METHODS FOR CLEANSING AND TREATING HAIR

Abstract

The present invention relates to compositions for cleansing hair fibers, in particular human hair fibers, comprising (a) cationic surfactants; (b) amphoteric surfactants; (c) thiol-based compounds; (d) nonionic surfactants; (e) cationic conditioning polymers; (f) optionally, amino silicones; (h) water; and (i) 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 cleansing and conditioning benefits and a use for hair care employing the cosmetic compositions of the present invention.
