Description

n-Lauroyl-L-Alanine is a high-purity, synthetic amino acid derivative where lauric acid is coupled to the amino group of L-alanine. This compound serves as a versatile and effective biocompatible surfactant and emulsifying agent, prized for its mildness and skin-friendly properties. It is primarily utilized in the formulation of high-end personal care products and as a building block in advanced biochemical research and synthesis.

Application

• Personal Care & Cosmetics: A key ingredient in mild facial cleansers, shower gels, shampoos, and shaving foams due to its excellent foaming and skin-conditioning properties.
• Biocompatible Surfactant: Used in pharmaceutical formulations and topical preparations where low irritation and high biocompatibility are required.
• Biochemical Research: Employed as a substrate or intermediate in enzymatic studies and the synthesis of more complex peptides or lipid conjugates.
• Specialty Detergents: Formulated into high-performance, gentle cleaning products for sensitive applications.
