Abstract: Composition may be prepared in a single DEFI reactor comprising mixtures of (1) DEFI (directly esterified fatty acyl isethionate) and (2) a compound produced by the reaction of (a) isethionate with a fatty acid replacement (e.g., a multicarboxylic fatty acid, a fatty acid); or (b) fatty acid with an isethionate replacement (e.g., C2-C24 alcohols, C2-C20 organic acids, amines). Such mixtures are milder than DEFI alone while retaining substantially same foaming benefit.
