Abstract
A stearoyl lactylate salt composition and method of production thereof wherein the composition has improved handling and storage characteristics. The lactylate salt is thermally mixed with from about 2% to about 30% (by weight) of hydrogenated stearin which has from about 50% to 100% (by weight of fatty acid) C.sup.18 fatty acid and an iodine value of less than 7.
