Abstract
Abstract wherein R1 is a monovalent hydrocarbon radical of eight to 24, preferably 10 to 20 carbon atoms; R2 is an alkyl or alkylol radical containing one to six carbon atoms, and R3 is an alkylol radical containing one to six carbon atoms, and salts thereof. The reaction mixture consists of sulfonated mono-, di-, and/or tri-esters, depending on the number of reactive hydroxyl groups in the alcoholamine and the amount of dicarboxylic acid utilized. These novel esters and salts thereof uniquely possess both detergency and softening properties. Novel sulfosuccinates of 2-hydroxy alkyl tertiary alcohol amines having the structural formula:
