This synthetic compound is a viscous, water - soluble yellow liquid . </P> <P> Polysorbate 80 is derived from polyethoxylated sorbitan and oleic acid . The hydrophilic groups in this compound are poly ethers also known as polyoxyethylene groups, which are polymers of ethylene oxide . In the nomenclature of polysorbates, the numeric designation following polysorbate refers to the lipophilic group, in this case the oleic acid (see polysorbate for more detail). </P>

Polysorbate 80 more soluble in water at lower temperatures
