Polysorbates are a class of emulsifiers used in some pharmaceuticals and food preparation. They are often used in cosmetics to solubilize essential oils into water-based products. Polysorbates are oily liquids derived from ethoxylated sorbitan (a derivative of sorbitol) esterified with fatty acids.
Polysorbate 20 (polyoxyethylene (20) sorbitan monolaurate) CAS 9005-64-5
Polysorbate 40 (polyoxyethylene (20) sorbitan monopalmitate) CAS 9005-66-7
Polysorbate 60 (polyoxyethylene (20) sorbitan monostearate) CAS 9005-67-8
Polysorbate 80 (polyoxyethylene (20) sorbitan monooleate) CAS 9005-65-6
( The number 20 following the 'polyoxyethylene' part refers to the total number of oxyethylene -(CH2CH2O)- groups found in the molecule. The number following the 'polysorbate' part is related to the type of fatty acid associated with the polyoxyethylene sorbitan part of the molecule. Monolaurateis indicated by 20, monopalmitate is indicated by 40, monostearate by 60, and monooleate by 80.)
