Science
Mechanism of Action
Operating as an amino acid-derived surfactant, SODIUM LAUROYL HYDROXYETHYL BETA-ALANINATE functions by creating an emulsion between oil-based impurities and water, facilitating their removal from the skin. Its unique structure, featuring hydroxyl groups, encourages the formation of fine, highly elastic, and dense foam by attracting adjacent surfactant molecules. Beyond its primary cleansing action, this ingredient also helps to minimize transepidermal water loss after washing, thereby supporting the skin's moisture barrier.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has categorized SODIUM LAUROYL HYDROXYETHYL BETA-ALANINATE with 'insufficient data' for a comprehensive safety assessment. While generally considered mild, anecdotal evidence suggests a potential for irritation in individuals with highly sensitive skin, especially when utilized in higher concentrations within a formula.
