Description

Sodium n-Dodecyl-β-Alaninate is a high-purity anionic surfactant derived from the amino acid β-alanine. This compound matters for formulators seeking a mild, biodegradable surfactant with excellent foaming and cleansing properties, particularly in personal care applications. Industries that need it include manufacturers of premium skin cleansers, shampoos, and other cosmetic products where mildness and skin compatibility are critical. Its structure offers a favorable balance between detergency and low irritation potential.

Application

• Primary Surfactant in Mild Cleansers: Used as the main foaming agent in facial cleansers, body washes, and baby shampoos due to its gentle nature.
• Cosmetic & Toiletry Formulations: Incorporated into shampoos, shower gels, and liquid soaps for its rich lather and skin-friendly profile.
• High-End Personal Care Products: Ideal for sensitive skin formulations, sulfate-free product lines, and dermatological cleansers.
• Industrial & Institutional Cleaners: Applied in formulations requiring effective yet biodegradable surfactants, such as some industrial detergents.
• Co-surfactant Systems: Functions effectively in blends with amphoteric or nonionic surfactants to optimize foam quality and viscosity.
