| Description | Span-85 (Sorbitan trioleate) is a synthetic non-ionic emulsifier, which is prepared by partial esterification of sorbitol or sorbitan with food grade palmitic acid. It has low viscosity and the smallest HLB value, so it has the strongest lipophilicity. It is an excellent water-in-oil (w/O) emulsifier and an O/w type auxiliary emulsifier. |
