Product Description

Span 60, chemically known as Sorbitan Monostearate, is a non-ionic surfactant and emulsifier derived from sorbitol and stearic acid. It appears as a white to pale-yellow waxy solid with excellent emulsifying, stabilizing, and dispersing properties. With a Hydrophilic-Lipophilic Balance (HLB) value of about 4.7, Span 60 is ideally suited for water-in-oil (W/O) emulsions and is one of the most commonly used emulsifiers in pharmaceutical, cosmetic, food, and industrial formulations.

Its versatility and compatibility with other non-ionic surfactants such as Tween 60 (Polysorbate 60) make it valuable for creating stable and uniform emulsions. Span 60 also acts as a consistency enhancer, improving the texture and stability of creams, lotions, and ointments.
