Description

n-(2-Hydroxyethyl)-n-(2-Hydroxyhexadecyl)-β-Alanine is a high-purity amphoteric surfactant and betaine derivative, valued for its excellent mildness, foaming properties, and compatibility with other ingredients. This compound is essential for formulators seeking to enhance the performance and skin-feel of personal care and industrial cleaning products. It is primarily needed by manufacturers in the cosmetics, home care, and industrial surfactant sectors.

Application

• Personal Care Formulations: As a primary or secondary surfactant in mild shampoos, body washes, facial cleansers, and baby care products.
• Cosmetic Products: Used in conditioning systems and foam boosters for creams, lotions, and shaving preparations.
• Home & Institutional Cleaning: An effective component in dishwashing liquids, hard surface cleaners, and all-purpose cleaners for its detergency and foam stability.
• Industrial Surfactant Blends: Serves as an emulsifier, viscosity modifier, and antistatic agent in textile processing, agrochemicals, and oilfield chemicals.
• High-Performance Detergents: Valued in formulations requiring stability across a wide pH range and in the presence of electrolytes.
