Abstract Pure 3‐sulfopropylesters, ethers and amides were prepared from fatty acids, alcohols and amides by reaction with 1,3‐propanesultone. Their solution properties, including Krafft point, critical micelle concentration, lime soap dispersing power and detergency, were compared with those of the analogous 2‐sulfoethyl esters. The N‐3‐sulfopropylamides exhibited superior lime soap dispersing power as well as detergency in soap‐based formulations at 300 ppm water hardness. The sulfopropyl ethers and amides displayed excellent stability to acid and alkaline hydrolysis. The sulfopropyl esters were much more stable to alkaline hydrolysis than the sulfoethyl esters, but only slightly more stable to acid hydrolysis.
