Abstract

A homogeneous liquid nonionic based antimicrobial conditioning shampoo which includes about 0.5 to 2.5% of the antimicrobial agent, 1-imidazolyl-1-(4-chlorophenoxy)-3,3-dimethylbutan-2-one, solubilized in an aqueous solution of critical amounts of a four component mixture of the following specific non-ionic ingredients:

a. about 2-20% by weight of a polyoxyethylene hexitan mono-higher fatty acid ester,

b. about 4-10% by weight of a tertiary amine oxide,

c. about 1-7% by weight of a fatty acid mono- or di-ethanolamide,

d. about 0.05-1.0% by weight of a polyacrylamide having a molecular weight of 100,000 to 3,000,000. This shampoo is transparent in appearance and should preferably contain 65-80% water.

Claims

1. A homogeneous, liquid, nonionic based, antimicrobial, conditioning shampoo containing about 0.5-2.5% of 1-imidazolyl-1-(4-chlorophenoxy)-3,3-dimethyl butan-2-one solubilized in an aqueous vehicle, wherein the aqueous vehicle constitutes about 65-80% by weight of water containing four nonionic components comprising about 2-20% by weight of a polyoxyethylene hexitan mono-higher fatty acid ester having 10-20 carbon atoms in the higher acyl thereof and 10-80 mols ethylene oxide per mol, about 4-10% by weight of a dimethyl higher alkyl amine oxide having 10-16 carbons in the higher alkyl thereof, about 1-7% by weight of a higher fatty acid mono- or di-ethanolamide, and about 0.05-1.0% weight of a water-soluble polyacrylamide having an average molecular weight of 100,000 to 3,000,000.

2. A shampoo in accordance with claim 1, wherein the polyoxyethylene hexitan monoester is polyoxyethylene sorbitan monolaurate containing 20 mol ethylene oxide per mol.

3. A shampoo in accordance with claim 2, wherein the amine oxide is dimethyl myristylamine oxide.

4. A shampoo in accordance with claim 3, wherein the ethanolamide is cocomonoethanolamide.

5. A shampoo in accordance with claim 1, wherein the shampoo is a clear liquid.

6. A shampoo in accordance with claim 1, which includes up to 2% by weight of a cationic quaternized polymer, wherein said cationic polymer is the reaction product of dimethyl sulfate with the copolymer of vinylpyrrolidone and dimethylaminoethylmethacrylate.

7. A method of simultaneously cleansing and conditioning hair which comprises shampooing with the composition of claim 3.
