Sorbitan Mono Laurate (SML)

Overview

Sorbitan Mono Laurate (SML), commonly known by its trade name Span 20 or Sorbitan Laurate (INCI name), is a highly versatile and widely utilized non-ionic surfactant derived from sorbitol and lauric acid. As a lipophilic (oil-loving) emulsifier with an approximate HLB value of 8.6, SML plays a critical role in stabilizing oil-in-water (O/W) emulsions, dispersing pigments, and modifying rheology across a myriad of industrial applications. CanCastor, as a leading global supplier, ensures its SML meets the rigorous specifications demanded by USP, BP, FCC, and REACH standards.

Our extensive experience in the oleochemical industry ensures the production of SML with exceptional purity and consistency. This makes it an indispensable ingredient in sensitive formulations, from pharmaceuticals and food products to high-performance cosmetics and specialty industrial additives. Its mild nature, broad pH compatibility, and excellent thermal stability contribute to its widespread adoption, providing reliable performance and enhancing product longevity. We pride ourselves on the meticulous control over our manufacturing processes, ensuring every batch of Sorbitan Mono Laurate delivers on the promise of quality and efficacy that our B2B clients expect.
