Abstract
The present invention relates to a process for manufacturing improved color surfactant agglomerates, particularly comprising methyl ester sulfonates, for use in detergent compositions, said process comprising sulfonation of methyl ester, digestion of the sulfonation product, esterification of said sulfonated product to produce an acid product and agglomeration of said acid product, characterized in that said acid product is exposed to a solid bleaching agent immediately prior to or during agglomeration of said acid product.
Claims11
A process for making improved color surfactant agglomerates comprising methyl ester sulfonate for use in detergent compositions, said process comprising the steps of sulfonation of methyl ester, digestion of the sulfonation product, esterification of said sulfonated product to produce an acid product and agglomeration of said acid product, wherein said acid product is exposed to a solid bleaching agent during agglomeration.
In a process for making improved color surfactant agglomerates containing methyl ester sulfonate surfactant for use in detergent compositions, which process comprises the steps of:
- (i) sulfonating a methyl ester to produce a sulfonation product;
- (ii) digesting the sulfonation product,
- (iii) esterifying the digested sulfonation product to produce an acid product, and
- (iv) agglomerating said acid product, the improvement which comprises contacting said acid product at a temperature of between about 60.degree. C. and 90.degree. C. with a solid percarbonate or perborate bleaching agent while simultaneously or shortly thereafter dry neutralizing said acid product.
