Abstract Amides and 2‐alkyl‐N‐(2‐hydroxyethyl)‐imidazolines were converted into various types of sulfated or sulfonated amphoteric lime soap dispersants. The alkylimidazolines could be readily hydrolyzed to give amidoamines. The cyclized amphoteric surfactants were generally superior in detergency and lime soap dispersing ability to analogous surfactants derived from amidoamines. Some of the cyclized surfactants, when formulated with soap and silicate builder, washed about as well under the test conditions as a control containing 50% sodium tripolyphosphate.
