Lauryl Betaine is quite a beneficial ingredient used in personal care and cosmetic products due to it being a surfactant and having good emulsifying properties. It has a chemical formula of C16H33NO2 and is a liquid with a clear to pale yellow color and a slight odor. As a surfactant, it helps to mix oil and water-based ingredients, making it useful in shampoos, body washes, and other cleansing products. As an emulsifier, it stabilizes and thickens cosmetic formulations, preventing separation and maintaining texture. Lauryl Betaine is also known for its mildness and low irritation potential, making it a popular choice in products designed for sensitive skin.
