The Krafft points of monosodium salts of A-acylglutamic acids were determined by the eiectric conductivity method. The Krafft points were a few degrees beiow the ciear points, the temperatures at which the surfactant dissolved completely [4]. The monosodium salt of A-oleoyl-L-glutamic acid hardly hydrolyzed because it had an affinity with water and the Krafft point is lower. Triethanolamine salts of A-acylglutamic acid are generally more soluble in water and less irritating on the skin and have a lower Krafft point, compared with the corresponding sodium salts.
