Description

Sodium 1-Lauroyl-L-Prolinate is a high-purity amino acid-based surfactant derived from L-proline and lauric acid. This compound matters for formulators seeking a mild, biodegradable, and high-performance surfactant with excellent foaming and cleansing properties. It is primarily needed by manufacturers in the personal care, cosmetics, and high-end detergent industries for creating gentle yet effective products.

Application

• Primary Surfactant in Facial Cleansers & Makeup Removers: Valued for its mildness and ability to maintain skin barrier function.
• Foam Booster & Stabilizer in Shampoos and Body Washes: Enhances lather quality and provides a rich, creamy foam.
• Key Ingredient in Baby Care Products: Its amino acid origin and low irritation potential make it ideal for sensitive skin formulations.
• Co-surfactant in Syndet Bars (Syndet Bars): Improves mildness and skin feel in synthetic detergent bars.
• Formulation Aid in Premium Liquid Hand Soaps: Contributes to a luxurious feel and effective cleansing without over-drying.
• Component in Mild Oral Care Products: Used in some toothpaste and mouthwash formulations for gentle foaming action.
