Abstract
The present invention is directed to a solid cosmetic composition for keratin fibers, preferably human keratin fibers, more preferably human hair, comprising: one or more non-silicone lipophilic compound(s) having a melting point above 25° C. under atmospheric pressure, one or more pulverulent excipient(s), one or more cationic and/or cationizable compound(s), wherein the concentration of pulverulent excipients is 1% by weight or more, calculated to the total weight of the composition, and wherein the total concentration of water is less than 10% by weight, preferably less than 5% by weight, more preferably less than 1% by weight, still more preferably less than 0.5% by weight, calculated to the total weight of the composition.
Claims13
A solid cosmetic composition for keratin fibers, comprising compounds a) to c):
- a) at least one non-silicone lipophilic compound having a melting point greater than 25° C. under atmospheric pressure,
- b) at least one pulverulent excipient,
- c) at least one compound selected from the group consisting of a cationic compound and a cationizable compound,
- wherein a total concentration of water is less than 10% by weight, calculated based on the total weight of the composition,
- wherein the at least one pulverulent excipient b) is at least one compound selected from the group consisting of a chemically unmodified cellulose, nylon powder, and rice starch,
- wherein the at least one compound c) is a quaternary ammonium salt surfactant selected from the group consisting of behentrimonium chloride, behentrimonium methosulfate, steartrimonium chloride, soytrimonium chloride, and a combination thereof,
- wherein a total concentration of the at least one pulverulent excipient b) is from 2% to 12.5% by weight, calculated based on the total weight of the composition,
- wherein the at least one non-silicone lipophilic compound a) is a C12 to C22 fatty alcohol selected from the group consisting of cetyl alcohol, stearyl alcohol, cetearyl alcohol, and a mixture thereof;
- a C12 to C22 fatty acid monoester of a C6 to C22 alcohol selected from the group consisting of myristyl myristate, cocoa butter, shea butter, and a mixture thereof;
- or a combination thereof,
- wherein a total concentration of the at least one non-silicone lipophilic compound a) is from 30% to 90% by weight, calculated based on the total weight of the composition, and
- wherein the composition is a conditioning bar being solid at 25° C. and atmospheric pressure.
