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 (C2H40) 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.

Commerdal products are mixtures of the partial esters of sorbitol and its mono-and di-anhydrides (13.2). Several sorbitan esters can be identified (Table 13.2). Such esters are water insoluble (low HLB) and oil soluble, and are used as water-in-oil emulsifiers. 

Commercial products are complex mixtures of partial esters of sorbitol and its mono- and di-anhydrides condensed with an approximate number of moles of ethylene oxide. The formula of a representative component is shown above. The polysorbates are miscible with water, as reflected in their higher HLB values (see Table 1.2), and are used as emulsifying agents for oil-in-water emulsions. 

There is a wide variety of possible structures based on the use of glycerol (v = 3), trimethylolpropane (n = 3), pentaerythritol (n = 4), and sorbitol (n = 6) or their mixture as polyol, reacting not only with phthalic anhydride (w = 2) but also with pyromellitic dianhydride (w = 4), citric acid (v = 4), trimellitic acid (v = 3), or their mixture as polyacid. The most important resins are those obtained from the polycondensation of 0-phthalic anhydride with glycerol, and the resulting network is represented hereafter.
