Span 40 Sorbitan Monopalmitate Surfactant
Span 40 (Sorbitan Monopalmitate) is a high-quality non-ionic surfactant synthesized through esterification of sorbitan with palmitic acid. With molecular formula C22H42O6, this light yellow granular solid features an HLB value of 6.7, making it an effective water-in-oil (W/O) emulsifier.
Beyond its primary emulsification function, sorbitan monopalmitate serves as a stabilizer, thickener for food, pharmaceutical, and cosmetic formulations. It also functions as a lubricant, softener, and finishing agent in textile manufacturing, and as a dispersant for printing ink applications.
