    摘要: A test method is described for comparing the relative affinity of products for a target substance using a substrate ordinarily and visibly sensitive to the products. The test method is useful in one embodiment for comparing the ability of harsh cleansers to remove fatty acids from the skin with mild cleansers that do not remove fatty acids to the same extent using a visually compelling substrate, such as a fresh cut flower.

    摘要: 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.
