Abstract

AbstractAn application of sodium N‐acyl‐l‐glutamate for detergent bars is described. The acyl radicals of cocoyl, hydrogenated tallowyl, semihydrogenated tallowyl, and lauroyl were used in the glutamates. The powder of sodium N‐acyl‐l‐glutamate was mixed with a suitable amount of water and milled; then the mixture was extruded and stamped into a bar. Bars were examined relating composition of acyl radicals of sodium N‐acyl‐l‐glutamates and properties of the bars or milling and molding properties. The other characteristics of the detergent bars were examined. It was found that attractive detergent bars can be made by using monosodium N‐acyl‐l‐glutamate as a component; that hardness, solubility, and lather characteristics of bars can be controlled by blending various monosodium N‐acyl‐l‐glutamates and adding moisture; that adjuvant can be used to improve the milling and stamping properties and characteristics of the monosodium N‐acyl‐l‐glutamate bar; and that the bars are less irritating and leave the skin feeling good.
