INTERMEDIATES AND SURFACTANTS USEFUL IN HOUSEHOLD CLEANING AND PERSONAL CARE COMPOSITIONS, AND METHODS OF MAKING THE SAME.

摘要

Disclosed herein are novel mixtures of scattered-branched chain fatty acids and derivatives of scattered-branched chain fatty acids of Formula I. Further disclosed are uses of these mixtures in cleaning compositions (e.g., dishcare, laundry, hard surface cleaners,) and/or personal care compositions (e.g., skin cleansers, shampoo, hair conditioners). Formula I wherein each R1 independently is H or CH₃, whith the proviso that 1,2, or R1 is CH₃; m is 1 or 2; n is 3,4,5,6,7,8, or 9; p is 1,2,3,4,5,6,7, or 8; and, Y CH₂ or absent, with the proviso that when: (a) Y is CH₂, Z is selected from the group consisting of hydroxyl, an alkoxyl, a sulfate, etc. (b) Y is absent, Z is selected from the group consisting of a caroxylic acid, a caroxylate, etc. In particular, the branching group(s) is/are methyl pending from even-numbered positions of the hydrocarbon chain. These are produced by culturing cells, enginnered to express propionyl-CoA carboxylase and/or methyl-malonyl-CoA mutase.
