A process is provided for preparing C-Cacyl amido compounds via reaction in a polyol (molecular weight 76 to 400) of interesterifying a fatty acid ester with an amino compound or salt thereof. The resultant mass of material will have a Hunter Lab Color Scale value L ranging from 70 to 100.

General method for preparing fatty acyl amido based surfactants

A process is provided for preparing C-Cacyl amido compounds via reaction in a polyol (molecular weight 76 to 400) of interesterifying a C-Calkyl ester of a C-Cfatty acid with an amino compound or salt thereof. The resultant mass of material will have a Hunter Lab Color Scale value L ranging from 70 to 100.

A process is provided for preparing C-Cacyl glycinate acid or salt thereof via reacting and heating reacting a mixture of glycine or salt thereof with a fatty acid ester in a medium selected from the group consisting of glycerol, propylene glycol and combinations thereof, and wherein the mixture has a pKa ranging from 9.5 to 13.

Method for preparing fatty acyl amido carboxylic acid based surfactants

A process is provided for preparing C-Cacyl glycinate acid or salt thereof via reacting and heating a mixture of glycine or salt thereof with a C-Calkyl ester of a C-Cfatty acid in a medium of glycerol or propylene glycol. The reaction proceeds well where the mixture is formulated to have a pKa ranging from 9.5 to 13.

A surfactant concentrate is provided that includes C-Cacyl amido compounds, a polyol and C-Cfatty acids. The concentrate is formed via an interesterification reaction between a fatty acid ester and an amino compound or salt thereof in a polyol. The resultant surfactant concentrate will have a Hunter Lab Color Scale value L ranging from 70 to 100.
