Product Description
Sorbitan Monostearate (Span 20) Nonionic Emulsifier, CAS 1338-39-2,Balanced HLB, Acid value ≤8 mgKOH/g with Excellent Emulsion Stability
Product Overview
Span 20 (sorbitan monolaurate) is a lipophilic non-ionic surfactant. It appears as a pale yellow to amber oily liquid at room temperature with an HLB value of 8.6. While insoluble in water, it is soluble in oils, alcohols, and hydrocarbon solvents. It is stable in weak acids and alkalis and exhibits good compatibility with various other surfactants.
This product offers excellent performance in water-in-oil emulsification, dispersion, wetting, and defoaming applications. It is commonly used in cosmetics, food products, coatings, plastics, textile auxiliaries, and pesticide emulsifiable concentrates. It can be combined with the Tween series to adjust the hydrophilic-lipophilic balance (HLB).
