Abstract
Direct esterification of α‐sulfopalmitic and α‐sulfostearic acids with excess ethylene glycol, glycerol, pentaerythritol and 2‐methoxyethanol was carried out in carbon tetrachloride to give products containing essentially monoesters. Surface active properties of these compounds were measured with emphasis on washing ability in combination with soap. The detergency of these esters was compared with those of hexitol and sucrose α‐sulfo fatty acid esters. Although the esters had moderate lime soap dispersing ability, their detergency showed synergism when combined with soap.
