Article
Lauryl betaine’s a skin care ingredient used as a cleansing agent and also to help promote foaming in rinse-off products like cleansers.
It’s often used as a secondary surfactant, or as a “booster,” letting other surfactants play the primary role, where it helps to stabilize foaming.
Although lauryl betaine can be plant derived, it’s also created synthetically, where in raw material form, it’s a clear liquid. Beyond skin care cleansers, it’s also featured in shampoos and body washes.
The Cosmetic Ingredient Review Expert Panel deemed lauryl betaine safe for use, noting that it appears in cosmetics and personal care products in amounts between 0.015% and 8.8%.
