Description

n-α-Lauroyl-L-Lysine is a high-purity, synthetic amino acid derivative where lauric acid is conjugated to the α-amino group of L-lysine. This molecular design imparts unique surface-active and conditioning properties, making it a valuable multifunctional ingredient for high-performance formulations. It is primarily sought after by manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking superior texture, stability, and skin compatibility.

Application

• Cosmetic & Personal Care: Acts as a high-performance surface treatment for pigments (e.g., titanium dioxide, mica, iron oxides) to improve dispersion, adhesion, and skin feel in foundations, eyeshadows, and sunscreens.
• Skin Care Formulations: Functions as a gentle, amino acid-based emulsifier and texture enhancer, providing a silky, non-greasy feel in creams, lotions, and serums.
• Makeup Products: Serves as a key ingredient for improving the smooth application, long-lasting wear, and water resistance of lipsticks, powders, and color cosmetics.
• Pharmaceutical Excipient: Used as a biocompatible lubricant and flow aid in tablet and capsule manufacturing, enhancing production efficiency.
• Hair Care Products: Provides conditioning effects, reduces friction, and improves combability in shampoos and conditioners.
• Functional Additive: Employed in specialty coatings and polymer composites to modify surface characteristics and improve material compatibility.
