Abstract

A transparent, highly viscous, liquid shampoo composition comprising, as critical components, (A) from about 1 to about 10% by weight of a polyoxyethylene alkyl ether having the formula (I): ##STR1## wherein R.sub.1 is alkyl having 8 to 14 carbon atoms, R.sub.2 is hydrogen or alkyl having 1 to 7 carbon atoms, and n denotes the mole number of added ethylene oxide units and its distribution is as follows: N = zero to one : up to 10%, N = 2 to 4 : at least 90%, with the proviso that n equals 3 is at least 50%, and N .gtoreq. 5 : up to 10%, And (B) from about 5 to about 40% by weight of alkyl sulfate alkylolamine salt in which the carbon atom number of the alkyl group is in the range of from 11 to 15 and the carbon atom number of the alkylol group is 2 or 3.

Dependent claims

A transparent, highly viscous, liquid shampoo composition consisting essentially of

A. from about one to about 10 weight percent of one or a mixture of compounds having the formula ##STR3## wherein R.sub.1 is alkyl having 8 to 14 carbon atoms, R.sub.2 is hydrogen or alkyl having one to 7 carbon atoms, and wherein
1. n is a number of from zero to one, for from zero to 10 weight percent of the total weight of component A,
2. n is a number of from 2 to 4, for from 90 to 100 weight percent of the total weight of component A, with the proviso that n is 3 for from 50 to 100 weight percent of the total weight of component A, and
3. n is a number of 5 or more, for from zero to 10 weight percent of the total weight of component A;
B. from about 5 to about 40 weight percent of alkyl (C.sub.11 to C.sub.15) sulfate alkylolamine (C.sub.2 to C.sub.3) salt, and
C. the balance is essentially water.
