Lumisorb PSTO 20 MO

PSTO 20 MO is a sorbitan trioleate that has been ethoxylated with approximately 20 moles of ethylene oxide resulting in a water soluble, oil in water emulsifier. PSTO 20 K is a mixture of partial esters of sorbitol and its anhydrides made from fatty acids, primarily oleic, which is then reacted with ethylene oxide to make it hydrophilic in nature.
