General description
Span® 80 is a sorbitan ester series of surfactant. It is produced by esterification of one or more sorbitan hydroxyl group with fatty acid. It is hydrophobic in nature. This non-ionic surfactant can be used to form oil-in-water emulsions and in combination with low HLB surfactants can form water-in-oil emulsions. EPA approved oil spill dispersant.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. This product is biodegradable surfactant, thus aligns with "Use of Renewable Feedstocks" and "Design for Degradation" principles of Green Chemistry, and belongs to "12 principles aligned" category of our greener alternatives.
Application
Span® 80 was suitable as surfactant in the preparation of Poly(divinylbenzene) emulsion-derived (PolyHIPE) solid foam. It may be suitable as emulsifier used to extract 24 samples of emulsion explosives with hexane which were analysed using GC-MS.
