一 خاصية المنتج．
Twain (or polysorbate) is a non-ionic surfactant with an unpleasant odor, warm and slightly bitter taste. It is a partial fatty acid ester of a series of polyoxyethylene sorbitan alcohol. It is widely used as an emulsifier and a solubilizer for oil-based substances. Polysorbate is generally regarded as a non-toxic and non-irritating material.
