Oleamidopropyl Betaine is an amphoteric surfactant derived from oleic acid, used in cleansers and shampoos to provide gentle foaming, cleansing, and conditioning while reducing the harshness of primary surfactants. It also functions as a viscosity enhancer and antistatic agent in rinse-off formulations.
