Abstract
Abstract A production process of a liquid detergent composition having both good detergency and little hand roughening action is presented. This liquid detergent composition can be produced by mixing an anionic surface active agent and a semi-polar nonionic surface active agent, each in the stage of an aqueous solution, and then, adding a specified arylsulfonic acid to this mixture in such a manner that the produced liquid detergent composition contains 6 to 25% by weight of the anionic surface active agent, 2 to 8% by weight of the semi-polar nonionic surface active agent and 0.2 to 3.0% by weight of the arylsulfonic acid.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
188 words
A process for producing a liquid detergent composition comprising the steps of: (a) mixing an aqueous solution of at least one anionic surface active agent selected from the group consisting of the water-soluble salts of alpha-olefin sulfonic acids having 12 to 16 carbon atoms, and the water-soluble salts of polyoxyethylene alkylethersulfates having alkyl groups of 9 to 15 carbon atoms and an average of from 4 to 6 oxyethylene units with an aqueous solution of at least one alkylamine oxide having the formula. ##STR3## wherein R 1 is an alkyl group of 10 to 14 carbon atoms, and R 2 and R 3 independently an alkyl or hydroxyalkyl group of 1 to 5 carbon atoms (b) adding, to the mixture, at least one arylsulfonic acid selected from the group consisting of benzene sulfonic acid, toluene sulfonic acid, xylene sulfonic acid and cumene sulfonic acid in an amount of from 0.2 to 3.0% by weight, based on the total weight of the liquid composition containing from 6 to 25% by weight of said anionic surface active agent and from 2 to 8% by weight of said alkyl amine oxide.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
25 words
A process as claimed in claim 1, wherein said water-soluble salts are alkali metal salts, alkaline earth metal salts, ammonium salts and alkanol amine salts.
