Abstract
Described are personal care compositions, comprising water, nonionic cellulose ethers having hydroxyethyl groups and being further substituted with one or more hydrophobic substituents, and at least one hair fixative polymer, moisturizer, conditioner, humectant, cationic conditioning polymer, antioxidant, anti-aging active, or sun care active.
Claims15
A personal care composition, comprising:
- water;
- a hydroxyethyl cellulose substituted with at least one hydrophobic substituent selected from the group consisting of nonylphenyl glycidl ether, 3-n-pentadecenylphenyl glycidyl ether, hexadecyl glycidyl ether, octadecyl glycidyl ether, docosyl glycidyl ether, 1,2-epoxy hexadecane, 1,2-epoxyoctadecane and C8-32 alkyl halide wherein the substituted hydroxyethyl cellulose has a weight average molecular weight of from 1,000,000 to 2,500,000;
- and
- at least one hair fixative polymer, moisturizer, conditioner, humectant, cationic conditioning polymer, antioxidant, anti-aging active, or sun care active.
1 more element
A method for stabilizing a personal care composition against heat collapse, comprising:
- incorporating into the personal care composition a hydroxyethyl cellulose substituted with at least one hydrophobic substituent selected from the group consisting of nonylphenyl glycidyl ether, 3-n-pentadecenylphenyl glycidyl ether, hexadecyl glycidyl ether, octadecyl glycidyl ether, docosyl glycidyl ether, 1,2-epoxy hexadecane, 1,2-epoxyoctadecane and C8-32 alkyl halide wherein the substituted hydroxyethyl cellulose has a weight average molecular weight of from 1,000,000 to 2,500,000.
