Tween 60 /Polysorbate 60 is used in imitation cream, baked goods and frozen desserts. It works in a similar manner as monoglycerides and diglycerides, but requires smaller amounts. Polysorbate 60 helps whiteners dissolve in coffee, keeps dill oil solubilized in dill pickle jars, prevents baked good from going stale, and prevents oil from desolubizing in artificial whipped cream. Polysorbate 60 is well-known as an additive in the popular snack cakes Twinkies.

( 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.)
