Uses
Tween 60 is an emulsifier manufactured by reacting stearic acid with sorbitol to yield a product which is reacted with ethylene oxide. It is a nonionic, waterdispersible surface-active agent which is very hydrophilic. It is also termed polysorbate 60. It is used in whipped vegetable toppings for overrun and lightness; in cakes for increased volume and fine grain; in icings and confectionery for lightness and syneresis control; and in salad dressing for emulsion stability. It is frequently used with sorbitan monostearate or monoand diglycerides. The typical usage range is 0.10–0.40%.
