Nonionic shampoo
First Claim
1. A nonionic shampoo suitable for leaving washed hair in a manageable state consisting essentially of, by weight 3 to 30% of an amine oxide having two short chain and one long chain substituents on the nitrogen thereof wherein the short chain substituents are selected from the group consisting of lower alkyls and lower hydroxyalkyls of 1 to 4 carbon atoms and the long chain substituent is selected from the group consisting of higher alkyls and higher acylamido lower alkyls in which the higher alkyls are of 10 to 20 carbon atoms and the lower alkyls are of 1 to 4 carbon atoms;
- 2 to 30% of a polyoxyethylene hexitan mono-higher fatty acid ester having from 10 to 20 carbon atoms in the higher fatty acyl thereof and from 10 to 100 moles of ethylene oxide per moles;
a nonionic detergent selected from the group consisting of 6 to 30% of higher alkoxy polyoxyethylene ethanols wherein the higher alkoxy is of 10 to 20 carbon atoms and the ethylene oxide content including the CH2 CH2 O--of the ethanol, is from 6 to 20 mols per moles, 6 to 30% of C10 -C20 alkyl glycosides, 6 to 30% of mixtures of said polyoxyethylene ethanols and said alkyl glycosides, and a mixture of 1 to 6% of a C10 -C20 acyl C2 -C3 mono- or di- alkanolamide and 0.05% to 1% of a polyacrylamide having a weight average molecular weight in the range of 100,000 to 3,000,000; and
25 to 89% water;
said shampoo being essentially free of ions and having a conductivity below 2,000 microhmos/cm., having a pH in the range of 5 to 10 and exhibiting good foaming power in the presence of sebum soil at use concentration.

Abstract
An all nonionic liquid shampoo which includes an amine oxide, a polyoxyethylene hexitan mono-higher fatty acid ester, and at least one of a higher alkoxy polyoxyethylene ethanol, an alkyl glycoside and a mixture of glycoside, a higher fatty acid lower alkanolamide and polyacrylamide. Optionally, the mixture of higher fatty acid lower alkanolamide and polyacrylamide may be present in the liquid shampoo containing amine oxide, polyoxyethylene hexitan mono-higher fatty acid ester and the higher alkoxy polyoxyethylene ethanol and/or alkyl glycoside. Another optional constituent is a polyethylene glycol higher fatty acid ester. The shampoos are essentially free of ions and are desirably completely free of ionic materials with the pH essentially neutral.
