Description

n-Lauroyl-L-Aspartic Acid is a high-purity, amphiphilic amino acid derivative, synthesized from L-aspartic acid and lauric acid. This compound matters for its unique surfactant and chelating properties, making it a valuable multifunctional ingredient in advanced formulations. Industries requiring mild, biodegradable, and effective performance chemicals, such as personal care, cosmetics, and specialty detergents, are the primary users of this material.

Application

• Primary Surfactant/Cleansing Agent in mild facial cleansers, shower gels, and shampoos.
• Skin Conditioning & Moisturizing Agent in anti-aging serums, lotions, and creams due to its amino acid backbone.
• Foam Booster & Stabilizer in sulfate-free and syndet bar formulations.
• Metal Ion Chelator in cosmetic and industrial cleaning products to improve efficacy in hard water.
• Intermediate for the synthesis of more complex peptide-based surfactants and active pharmaceutical ingredients (APIs).
• Biodegradable Specialty Additive in eco-friendly industrial and institutional cleaning products.
