DESCRIPTION

Polysorbate 60 occurs as a yellow to orange colored, oily liquid or semigel. It is a mixture of stearate and palmitate partial esters of sorbitol and sorbitol anhydrides condensed with approximately 20 moles of ethylene oxide (C₂H₄O) for each mole of sorbitol and its mono- and dianhydrides. It is soluble in water, in aniline, in ethyl acetate, and in toluene; but, it is insoluble in mineral oil and in vegetable oils.
