Abstract
A method of producing a synthetic detergent soap base, comprising dissolving in an n-acyl sarcosine at an elevated temperature a fatty acid, and neutralizing the mixture with a base at a temperature sufficient to maintain fluidity to a pH of from about 4.5 to about 9.5. The resulting product is non-irritating and non-drying, and exhibits apparent skin substantivity and pleasant skin feel.
Claims7
A method of producing synthetic detergent soap base consisting essentially of using, as the solvent, an N-acyl sarcosine selected from the group consisting of lauroyl sarcosine, cocoyl sarcosine, myristoyl sarcosine and oleoyl sarcosine, by dissolving a fatty acid in said solvent consisting of said N-acyl sarcosine at an elevated temperature and neutralizing the acid mixture with alkali at a temperature sufficient to maintain fluidity, to a pH of from about 4.5 to about 9.5.
