Science
Mechanism of Action
This ingredient functions as a mild anionic surfactant by lowering the surface tension of water, allowing for the effective emulsification and removal of dirt, oil, and makeup. As an 'Alanine-type' surfactant, it is designed to cleanse thoroughly without disrupting the skin's barrier, promoting a non-taut, clean sensation post-rinse.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically evaluated Sodium Myristoyl Methyl Beta-Alanine. However, the structurally related class of Fatty Acyl Sarcosines and Sarcosinate Salts has been deemed safe for use in rinse-off products, and for leave-on products at concentrations up to 5%. A general caution for this class is to avoid use in cosmetic products where N-nitroso compounds might form. Furthermore, EWG assesses this ingredient with 'LOW' concern across categories including Cancer, Allergies & Immunotoxicity, and Developmental & Reproductive Toxicity.
