Abstract
Abstract Novel sulfosuccinates of 2-hydroxy alkyl tertiary alcohol amines having the structural formula: ##STR1## wherein R 1 is a monovalent aliphatic hydrocarbon radical of 8 to 24, preferably 10 to 20 carbon atoms; R 2 is an alkyl or alkylol (hydroxy substituted alkyl) radical containing 1 to 6 carbon atoms, and R 3 is an alkylol radical containing 1 to 6 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.
