Lumisorb PSTS 20K

Lumisorb PSTS 20 K (Polysorbate 65) is a sorbitan tristearate that has been ethoxylated with approximately 20 moles of ethylene oxide resulting in a water soluble, oil in water emulsifier. Polysorbate 65 is a mixture of partial esters of sorbitol and its anhydrides made from fatty acids, primarily stearic, which is then reacted with ethylene oxide to make it hydrophilic in nature.
