PREPARATION OF N-LONG CHAIN ACYLAMINO ACID TYPE SURFACTANT AND LIQUID DETERGENT COMPOSITION CONTAINING SAID SURFACTANT

摘要

PURPOSE:To eliminate the formation of turbidity or sedimentation at the time of the compounding with a liquid detergent, by reacting fatty acid chloride, which is obtained by reacting carbonyl chloride and fatty acid, and amino acid in the presence of alkali. CONSTITUTION:Carbonyl chloride is reacted with fatty acid to prepare fatty acid chloride which is, in turn, reacted with amino acid in the presence of alkali to prepare an N-long chain acylamino acid type surfactant. As fatty acid chloride, 8-20C saturated or unsaturated one is pref. and, concretely, there are layryl chloride and palmytoyl chloride, etc. As the obtained N-long chain acylamino acid type surfactant, there are N-long chain acylglutamic acid, N-long chain acylsalcosine and N-long chain acyl-beta-alanine, etc.
