Claims13
A colorant for keratin fibers based on oxidation dye precursors and/or direct dyes, said colorant containing a combination of (a) at least one nonionic, amphiphilic associative thickener, (b) at least one fatty alcohol that is liquid at 25° C. and (c) a PEG-150/stearyl alcohol/SMDI copolymer in a suitable cosmetic carrier:
- wherein said at least one nonionic, amphiphilic associative thickener is selected from the group consisting of polyether-1, PEG-180/octoxynol-40/TMMG copolymer, and PEG-180/laureth-50/TMMG copolymer;
- and
- wherein the at least one fatty alcohol is selected from the group consisting of decanol, undecanol, lauryl alcohol, 2-octyl-1-dodecanol, oleyl alcohol, linoleyl alcohol, and linolenyl alcohol.
A ready-to-use oxidative hair colorant containing an oxidant, at least one oxidation dye precursor and a combination of from 0.1 to 2.5 wt. % of at least one nonionic, amphiphilic associative thickener;
- from 0.1 to 20 wt. % of at least one fatty alcohol that is liquid at 25° C. and from 0.01 to 2 wt.% of PEG-150/stearyl alcohol/SMDI copolymer, in a medium suitable for coloring hair;
- wherein said at least one nonionic, amphiphilic associative thickener is selected from the group consisting of polyether-1, PEG-180/octoxynol-40/TMMG copolymer, and PEG-180/laureth-50/TMMG copolymer;
- and
- wherein the at least one fatty alcohol is selected from the group consisting of decanol, undecanol, lauryl alcohol, 2-octyl-1-dodecanol, oleyl alcohol, linoleyl alcohol, and linolenyl alcohol.
