Science
Mechanism of Action
Functioning as an amphoteric surfactant, Oleyl Betaine effectively lowers surface tension within cosmetic formulations, facilitating optimal product spread and delivery. As a skin-conditioning agent, it actively contributes to maintaining skin health and integrity. Furthermore, it acts as an osmolyte, helping to stabilize lipid membranes, promote tight junction integrity, and provide anti-irritation and anti-inflammatory support to the skin.

Stability
Oleyl Betaine, typically supplied in solution, demonstrates stability across a broad pH range. Its amphoteric nature means it possesses both positive and negative charges, and as a zwitterion at approximately pH 5.5, it can function as a buffer, contributing to formulation stability. While pure Oleyl Betaine shows very low water solubility, its surfactant properties enable functional dispersibility in both aqueous and oil phases.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Oleyl Betaine safe for use in cosmetics, provided it is formulated to be non-irritating. The maximum reported use concentration for similar alkyl betaines, like lauryl betaine, is 8.8% in rinse-off hair products. It is important to note that FDA approval for betaine hydrochloride (a different chemical form) for medical use does not directly apply to Oleyl Betaine in cosmetic applications.
