The Uses of Span 80
sorbitan oleate is a mild emulsifier derived from sugar.
Definition
ChEBI: Sorbitan monooleate is a fatty acid ester.
General Description
Span 80 is a nonionic surfactant.
Safety Profile
A skin irritant. Human mutation data reported. When heated to decomposition it emits acrid smoke and irritating fumes.
Property
The hydrophilic-lipophilic balance value (HLB value) of the Span 80 is 4.3, and the Span 80 can be mixed and dissolved with oil to form a water-in-oil (W/O) emulsifier. It is a non-ionic surfactant and has excellent emulsifying, dispersing, foaming, moistening and other performance.
Preparation
Span 80 is also called Span-80, chemical name is sorbitan monooleate, which is formed by esterifying sorbitan after dehydration and oleic acid.
