Abstract
Abstract A liquid detergent composition which comprises an anionic surface active agent of polyoxyalkylene alkyl ether sulfate type and a cationic surface active agent of mono-long chain alkyl quaternary ammonium salt type at a mol ratio of the former to the latter in the range of from 8:1 to 1:1 is not only mild to the human skin but also capable of demonstrating superb detergency.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
183 words
A liquid detergent composition in which the synthetic organic surfactant component consists essentially of a mixture of A. anionic surfactant having the formula ##STR2## wherein R' is alkyl having 8 to 16 carbon atoms, R" is H or CH 3 , m is the average number of mols of added ##STR3## units and is in the range of from 1 to 6 and M is an alkali metal, ammonium or alkanolamine B. cationic surfactant having the formula ##STR4## wherein R 1 is alkyl having 8 to 14 carbon atoms, R 2 and R 3 are CH 3 , C 2 H 4 OH or (C 2 H 4 O) 2 H, R 4 is CH 3 , C 2 H 4 OH, (C 2 H 4 O) 2 H or benzyl, and X is halogen, CH 3 SO 4 or C 2 H 5 SO 4 , the molar ratio of A:B being in the range of from 8:1 to 1:1, and the total weight of A plus B being from 1 to 40% by weight, based on the weight of said composition.
Claim 2
Dependent Claim
