Stearamidopropyl Morpholine Lactate

What is Stearamidopropyl Morpholine Lactate?

Stearamidopropyl Morpholine Lactate is a synthetic cationic surfactant formed by reacting stearic acid—a saturated fatty acid from vegetable or animal fats—with aminopropyl morpholine, then forming the lactate salt with lactic acid. This structure gives it amphiphilic properties, allowing it to interact effectively with hair shafts. Primarily featured in rinse-off hair care formulations like conditioners, detanglers, and styling aids, it functions by depositing a thin conditioning layer on hair cuticles. This neutralizes surface charge to combat static electricity, facilitates even distribution of other ingredients, and imparts a silky texture during combing, all while being water-dispersible for easy rinsing.
