Isopropyl lauroyl sarcosinate

Isopropyl lauroyl sarcosinate (CAS 230309-38-3), commercially known as Eldew SL-205, is an ester-based amino acid derivative used in personal care and pharmaceutical formulations. It functions simultaneously as an emollient, dispersant, and solubility enhancer, reducing the need for multiple functional ingredients in a single system. In skin and hair care, it improves spreadability.

This ingredient is ideal for anhydrous formulations such as cleansing oils, serums, and leave-on treatments while contributing a non-greasy skin feel. Formulators use it in color cosmetics to disperse pigments. It is frequently used in lipstick bases, foundations, and eye products, replacing conventional ester solvents. In sunscreen formulations, it aids UV filter solubilization and improves the texture of high-SPF systems.

Pharmaceutical topical preparations benefit from its carrier properties, supporting active ingredient delivery in ointment and cream bases. It is supplied as a clear to pale yellow liquid for industrial use. It is available in cosmetic-grade specification, with Eldew SL-205 being the most recognized commercial grade. Packaging typically follows standard industrial formats for large-scale operations.

Bulk supply is available for manufacturers requiring consistent quality and performance. This versatile ester remains a staple for high-performance personal care and pharmaceutical topical applications.
