Nonionic erucic acid ethoxylates give a solution behavior anticipated from the hydrophilic-lipophilic balance of the molecule; however, the increased molecular size as compared to ordinary surfactants results, e.g., in higher temperature stability of the surfactant aggregates. Anomalous solution behavior was found and investigated for anionic surfactants, triethanolammonium salts of erucic acid, and some shorter homologues. The effects are discussed in terms of the acid-base equilibria of the alkanolammonium counterion and the acid, together with effects due to the molecular size of the counterion.
