Polysorbate Tween

Polysorbate (also known as Tween) is formed by condensation of the residual hydroxyl group in the Span molecule with ETO. In the process of polyoxyethylene, transesterification occurs, and the ester group that was previously directly connected to the dehydrated sorbitol can be rearranged to the hydroxyl end of the oxyethylene chain. They are suitable for use as oil-in-water (O/W) emulsifiers, solvents, dispersants, stabilizers, antistatic agents, lubricants and cleaners.
It is used as an emulsifier in pesticides, pharmaceuticals, food and cosmetics.
