Overview

Span 60 is a biodegradable surfactant based on a natural fatty acid (stearic acid) and the sugar alcohol sorbitol. This sorbitan ester is highly effective at forming O/W emulsions, particularly when used in combination with its polyethoxylated derivative, Tween 60. Fatty acid composition: Stearic acid (C18:0) approx. 50%; balance primarily palmitic acid (C16:0). Chemical group: Nonionic Surfactants - Sorbitan Esters and Ethoxylated Sorbitan Esters
