Patent ID: 8642020

Claim:
A composition for treating keratin fibers, comprising, in a cosmetically acceptable medium: at least one oxidizing agent; at least one nonionic amphiphilic hydrophobic compound which is solid at ambient temperature chosen from steareth-2, steareth-3, steareth-4, steareth-5, steareth-6, ceteth-2, ceteth-3, ceteth-4, ceteth-5, ceteareth-2, ceteareth-3, ceteareth-4, ceteareth-5, beheneth-5, cocamide MEA, cocamide MIPA, cocamide DEA, stearamide MEA, stearamide DEA, myristamide DEA, myristamide MEA, polyglyceryl-2 distearate, polyglyceryl-3 distearate, polyglyceryl-2 stearate, polyglyceryl-3 stearate, peg-2 stearate, peg-3 stearate, peg-4 stearate, sorbitan distearate, sorbitan palmitate, sorbitan stearate, sorbitan tristearate, myristyl glucoside, cetearyl glucoside, and arachidyl glucoside; and at least one hydrophilic surfactant chosen from cationic and zwitterionic hydrophilic surfactants; wherein the at least one nonionic amphiphilic hydrophobic compound is present in an amount ranging from 2% to 30% by weight, relative to the total weight of the oxidizing composition; wherein the weight ratio of the at least one hydrophilic surfactant to the at least one nonionic amphiphilic hydrophobic compound ranges from 0.05:1 to 0.16:1; and further wherein the composition is in the form of an aqueous dispersion; with the proviso that the composition does not comprise hydrophilic surfactants other than cationic or zwitterionic hydrophilic surfactants.
