Span 20 (Sorbitane Monolaurate)

Product Description

Span 20, also known as Sorbitan Monolaurate, is a non-ionic surfactant and emulsifier widely used in pharmaceutical, cosmetic, food, and industrial formulations. It is derived from sorbitol and lauric acid, forming a viscous amber-colored liquid or semi-solid with excellent emulsifying, dispersing, and stabilizing properties.

Due to its low hydrophilic-lipophilic balance (HLB ≈ 8.6), Span 20 is particularly effective for water-in-oil (W/O) emulsions, making it an essential ingredient in creams, lotions, ointments, and oil-based formulations. It is also compatible with a wide range of surfactants and used in combination with Tween surfactants for optimized emulsion stability.
