Description

Nonadecyl 5-Oxo-L-Prolinate is a high-purity, long-chain fatty acid ester derivative of L-proline. This specialty chemical is valued for its unique amphiphilic structure, combining a lipophilic C19 alkyl chain with a hydrophilic pyrrolidone-based head group, which imparts valuable surface-active and conditioning properties. It is primarily sought by manufacturers in the personal care, cosmetic, and high-performance lubricant industries seeking advanced emolliency, film-forming, and anti-static effects.

Application

• Personal Care & Cosmetics: Acts as a premium emollient and conditioning agent in skin creams, lotions, hair conditioners, and sunscreens, providing a smooth, non-greasy feel and enhancing product spreadability.
• Hair Care Formulations: Used as a key ingredient in anti-frizz serums, leave-in conditioners, and styling products for its excellent detangling, shine-enhancing, and anti-static properties.
• Pharmaceutical Topicals: Serves as a penetration enhancer and emollient in topical ointments, creams, and transdermal delivery systems, improving skin feel and active ingredient bioavailability.
• Performance Lubricants & Release Agents: Functions as a friction modifier and mold release agent in specialized industrial and metalworking formulations.
• Chemical Synthesis: Employed as a versatile biochemical building block or intermediate in organic synthesis and peptide research due to its reactive ester group and chiral center.
• Surface Coatings: Imparts improved flow, leveling, and substrate wetting properties in high-end coating and ink formulations.
