Betaine

Betaine, also known as trimethylglycine, is a naturally occurring amino acid derivative primarily extracted from sugar beet molasses. Its unique zwitterionic structure allows it to function as both a humectant and osmoprotectant, helping skin cells maintain hydration under stress while also providing foam stabilization and viscosity enhancement in cleansing formulations. Formulators value betaine for its exceptional compatibility with all surfactant types, its ability to reduce irritation from harsh cleansers, and its multifunctional performance as both a moisturizer and conditioning agent.
