Abstract: The present invention relates to an aqueous composition comprising at least one dispersion of polymer particles in a non-aqueous medium, at least one cationic polymer and at least one anionic polymer. The present invention also relates to a cosmetic treatment process, notably a process for styling keratin fibres, in particular human keratin fibres such as the hair, using this composition. Finally, the present invention relates to the use of this composition for the cosmetic treatment of keratin fibres, in particular of human keratin fibres such as the hair, and in particular for styling the hair, i.e. for shaping and/or fixing the head of hair.

Abstract: The present disclosure relates to hair treatment compositions comprising: (a) at least one reducing agent selected from thiol-based compounds, non-thiol-based compounds, and mixtures thereof; (b) at least one non-polymeric and non-thiol, mono-, di-, and/or tri-carboxylic acid, and/or a salt thereof; (c) at least one alkaline agent; and (d) optionally, at least one cationic surfactant; wherein the pH of the composition is from about 2 to less than 7. The disclosure also relates to methods for imparting hair care benefits to the hair such as straightening effects, volume reduction, frizz control, manageability, cosmeticity and smooth feel, in addition to conditioning benefits.

Abstract: The present invention relates to a composition comprising: (a) one more compound(s) of thiolactone type, and (b) one or more silicones.

Abstract: The present invention relates to a composition comprising: (a) at least one compound of thiolactone type, and (b) one or more solvents, which may be identical or different, chosen from polar (non-)protic organic solvents; the pH of said composition being less than or equal to 7.

Abstract: The present invention relates to a process for treating keratin fibers, in particular the hair, comprising: a) the application, to said fibers, of a composition having a pH greater than or equal to 8, at 25° C., and comprising at least one amino acid chosen from those of formulae (I) and (II) below, and also the betaine forms thereof, the optical isomers thereof, the solvates thereof such as the hydrates, and the organic or inorganic base or acid salts thereof: in which formulae (I) and (II): R represents a hydrogen atom, or a linear or branched, preferably linear, C1-C5 alkyl group, said alkyl group being optionally substituted with at least one group chosen from hydroxyl, —C(O)—OH, —S(O)2—OH, —C(O)—O?, M+, and —S(O)2—O?, M+, with M+ representing a cationic counterion such as an alkali metal, alkaline-earth metal, or ammonium, n is 0 or 1; b) followed by a step of straightening/relaxing the keratin fibers by means of a straightening iron at a temperature of at least 100° C.
