Tween (or polysorbate) is a non-ionic surfactant with a peculiar smell, warm and slightly bitter. It is a series of partial fatty acid esters of polyoxyethylene sorbitan. It is widely used as an emulsifier and a solubilizer for oils. Polysorbate is generally regarded as a non-toxic and non-irritating material.
