Tween 60

Catalog	DGS9005678
CAS	9005-67-8
Description	Tween 60, also known as polysorbate 60, polyoxyethylene sorbitan monostearate, its molecular formula is C64H126O26. In general, it is a lemon-colored to orange oily liquid or semi-gel, with a slight special odor and a slightly bitter taste. Tween 60 is soluble in water, aniline, ethyl acetate and toluene, but insoluble in mineral oil and vegetable oil. Tween 60 has excellent emulsifying properties, and has the functions of wetting, foaming, and diffusion, and is widely used in textiles, medicine, water-based coatings and other industries.

Application	Tween 60 serves as a versatile emulsifier extensively used across various food applications to enhance texture and stability. As a nonionic, water-dispersible surface-active agent, it is produced by reacting stearic acid with sorbitol, followed by ethylene oxide treatment, yielding a product that is highly hydrophilic. Known also as polysorbate 60, Tween 60 plays a crucial role in whipped vegetable toppings to improve volume and lightness, in cakes to augment volume and create a fine grain, in icings and confectionery for enhancing lightness and controlling syneresis, and in salad dressings to maintain emulsion stability. Often utilized in combination with sorbitan monostearate or mono- and diglycerides, its typical usage range is between 0.10-0.40%.
