Science
Mechanism of Action
As an amphoteric surfactant, Stearamidopropyl Betaine reduces the interfacial tension between diverse phases within a formulation, thereby enabling superior cleansing and the generation of foam. Its mechanism further extends to conditioning the skin and hair, promoting a softer texture and improved manageability. It also acts as an antistatic agent, aids in maintaining optimal pH levels, and enhances the viscosity and spreadability of cosmetic products.
