Abstract

PROBLEM TO BE SOLVED: To obtain a surfactant compounded composition which comprises an acyloxyalkanesulfonate and a fatty acid ester, has good consistency, and can be processed more easily than the acyloxyalkanesulfonate itself by control ling the content of a 1-2C alkyl ester of fatty acid therein within a specified range. SOLUTION: The content of a 1-2C alkyl ester of a fatty acid in this surfactant is 0.1-10wt.% based on the content of the acyloxyalkanesulfonate. The acyloxyalkanesulfonate preferably has the formula R<1> COOR<2> SO3 M (wherein R<1> is a 5-31C alkyl or a 5-31C alkenyl; R<2> is a 2-4C alkylene or a 2-4C alkenylene; and M is an alkali metal, an alkaline earth metal, NH4 or a substituted ammonim ion). This surfactant is produced by esterifying a fatty acid with a hydroxyalkanesulfonate. Since coconut fatty acid is used actually, free coconut fatty acid will remain after esterification. The free coconut fatty acid will contain a lower fatty acid and have a malodor. For removing the malodor, a second fatty acid, for example, stearic acid is added to distill off the free coconut fatty acid.

である。BACKGROUND OF THE INVENTION Acyloxyalkanesulfonates are:
Anionic surfactants used inter alia in solid detergent compositions such as bar soaps. This surfactant is usually produced by a so-called direct esterification method by reacting sodium isethionate with excess free fatty acid. In this reaction, the viscosity of the reaction mixture sharply increases as the esterification proceeds. It is therefore known that it is necessary to add so-called consistency regulators so that highly viscous reactants can still be sufficiently stirred. Known such consistency modifiers are:
In particular, paraffins (European Patent Application Publication No. 0
246 471) and free fatty acids (International Patent No. 94/26866)
It is.

である。It is also known to use fatty acid esters as consistency regulators (EP-A-0 182 017). However, in the process described there, after the completion of the esterification reaction, the consistency modifier is distilled off as much as possible and the final product is substantially free of fatty acid esters. EP-A 0 262 420 likewise discloses the use of fatty acid esters as consistency regulators, but in this case they may remain in the final product. The only fatty esters possible therefrom are those derived from alcohols having at least three carbon atoms.
