Patent ID: 8653018

Claim:
A reaction mass concentrate of C 8 -C 22 acyl amido compounds prepared by a process comprising: (i) reacting an amino compound or salt thereof having a structure (I) with a C 1 -C 3 alkyl ester of a C 8 -C 22 fatty acid in a polyol medium, wherein, at 25 degrees Celsius, a reaction mixture pKa of from 9.5 to 13 is provided, wherein R 2 is hydrogen or a C 1 -C 5 alkyl radical; R 3 is hydrogen; R 4 is selected from the group consisting of (CH 2 ) m CO 2 X, (CH 2 ) m SO 3 X and glucosyl radicals; R 5 is selected from the group consisting of hydrogen, hydroxyphenyl, C 1 -C 6 hydroxyalkyl, C 1 -C 10 alkyl, benzyl, hydroxybenzyl, alkylcarbamido, thioalkyl, and carboxylic radicals; X is selected from hydrogen, metal ions, amine salts and C 1 -C 4 alkyl radicals; and m ranges from 0 to 6; and (ii) heating reactants from step (i) to form the C 8 -C 22 acyl amido compounds having a structure (II) wherein R is a C 7 -C 21 saturated or unsaturated alkyl radical; and (iii) recovering a reaction mass concentrate that, without further workup, has a Hunter Lab Color Scale value L ranging from 75 to 100, the concentrate comprising: a) from 40 to 90% by weight of C 8 -C 22 acyl amido compounds of structure (II); b) from 10 to 60% by weight of polyol; c) from 1 to 20% by weight of C 8 -C 22 fatty acids; and d) from 0 to 5% by weight of water, wherein the polyol medium includes polyol selected from the group consisting of glycerol, propylene glycol, dipropylene glycol, pentylene glycol, butylene glycol, isobutylene glycol and combinations thereof.
