1. A process for forming fatty acyl amido surfactants that comprises:
(i) reacting from 1 to 90% by weight of an alkali metal or alkaline earth metal salt of an amino compound, the compound having a structure (I) which is wherein R2 is hydrogen, CH2COOX or a C1-C5 alkyl radical; R3 is hydrogen; R4 is selected from the group consisting of (CH2)mCO2X, (CH2)mSO3X, CH2NR2(CH2)mOH and glucosyl radicals; R5 is selected from the group consisting of hydrogen, hydroxyphenyl, C1-C6 hydroxyalkyl, C1-C10 alkyl, benzyl, hydroxybenzyl, alkylcarbamido, thioalkyl, and carboxylic radicals; X is an alkali or alkaline earth metal cation; and m ranges from 0 to 6; and (a) from 10 to 99% by weight of a polyol of molecular weight ranging from 76 to 300; and (b) from 0 to 10% by weight of water, and (c) a basic salt containing catalyst selected form the group consisting of alkaline earth comprising metal containing hydroxide, phosphates, sulphates and oxides, wherein the oxides are selected from the group consisting of calcium oxide, magnesium oxide, barium oxide, sodium oxide, potassium oxide; (ii) heating reactants from step (i) to form acyl amido compounds having a structure (II) wherein R is C7-C21 saturated or unsaturated alkyl radical provided by the fatty acid ester; and the resultant mass has a Hunter Lab Coir Scale value ranging from 70 to 100; and (iii) recovering a resultant mass from the process. |
