A method for treating human keratin fibers such as the hair is described and comprises the application to the keratin fibers of a dye composition comprising at least one cationic acrylic copolymer and at least one pigment, and the application to the dyed keratin fibers of a makeup-removing composition comprising at least one hydrocarbon oil.

A hair-colouring composition comprising an estolide ester derived from ricinoleic acid and direct dyes.

Processes and a multi-component packaging unit (kit-of-parts) are provided for decolorizing keratinous material which has been colored by the application of at least one pigment. A process includes applying to the keratinous material a decolorizing agent comprising at least one anionic surfactant, and having a pH value of 1.0 to 3.5, and rinsing the decolorization agent from the keratinous material after a contact time.

A personal care composition is provided, including: a cosmetically acceptable carrier; and a silicon glycan of formula (I):

##STR00001##

wherein each A comprises an independently selected saccharide moiety; wherein each W is an independently selected beta-amino alcohol moiety; wherein each Y comprises an independently selected organosilicon moiety; wherein each R is independently selected from substituted or unsubstituted hydrocarbyl groups, ether moieties, amine moieties, and H; wherein each R.sup.1 is independently selected from substituted or unsubstituted hydrocarbyl groups and H; wherein each Z is an independently selected ether moiety; wherein each subscript a is independently 0 or 1; wherein subscripts x and y are each independently from ≥0 to <1; wherein subscript z is selected from >0 to 1; with the proviso that x+y+z=1; and wherein moieties indicated by subscripts x, y, and z may be in randomized or block form in the silicon glycan.

A multi-agent type hair treatment agent comprising a first composition containing component (A) and component (B); and a second composition containing component (C), wherein the weight ratio (H)/(C) of component (H) to component (C) in the second composition is less than 1. A hair treatment method comprising the steps of applying and rinsing the first composition to hair (i) and then applying the second composition to hair (ii). Component (A): a carboxylic acid having an inorganic value of 230 or more and 450 or less and an organic value of 50 or more and 250 or less, or a salt of the carboxylic acid Component (B): anionic surfactant Component (C): an aromatic sulfonic acid having a molecular weight of 300 or less or a salt thereof Component (H): cationic surfactant.
