Description

n-Octadecanoyl-L-Alanine Sodium Salt is a high-purity, amphiphilic amino acid derivative that combines the biocompatibility of L-alanine with the hydrophobic character of a stearoyl chain. This compound is valued for its surfactant and emulsifying properties, making it a versatile ingredient for formulating stable and mild systems. It is primarily sought after by manufacturers in the personal care, cosmetic, and pharmaceutical industries for applications requiring gentle yet effective surface activity.

Application

• Cosmetic & Personal Care Formulations: Acts as a mild surfactant, emulsifier, and skin-conditioning agent in cleansers, creams, lotions, and shampoos.
• Pharmaceutical Excipients: Used in the development of drug delivery systems, including liposomes and micelles, to enhance solubility and bioavailability of active ingredients.
• Biochemical Research: Serves as a model compound or reagent in studies of membrane biochemistry, protein-lipid interactions, and surfactant science.
• Specialty Surfactants: Employed in the formulation of high-value industrial and institutional cleaners where mildness and biodegradability are key requirements.
