( 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.)
