|Section2= |Section7= }} Polysorbate 80 is a nonionic surfactant and emulsifier often used in foods and cosmetics. This synthetic compound is a viscous, water-soluble yellow liquid. ==Chemistry== Polysorbate 80 is derived from polyethoxylated sorbitan and oleic acid. The hydrophilic groups in this compound are polyethers 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). The full chemical names for polysorbate 80 are: *Polyoxyethylene (20) sorbitan monooleate *(x)-sorbitan mono-9-octadecenoate poly(oxy-1,2-ethanediyl) The critical micelle concentration of polysorbate 80 in pure water is reported as 0.012 mM. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Polysorbate 80」の詳細全文を読む スポンサード リンク
