Abstract
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 1 is alkyl having 8 to 14 carbon atoms, R 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 ≧ 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.
