Polyoxyethylene Sorbitan Fatty Acid Ester (TWEEN)

Polyoxyethylene Sorbitan Fatty Acid Ester (TWEEN) is a type of nonionic surfactant. It is formed by the esterification reaction of sorbitan anhydride with fatty acids and then the addition polymerization with ethylene oxide. Its unique "hydrophilic-lipophilic" amphoteric structure (with adjustable HLB values ranging from 8 to 18) makes it an efficient phase interface regulator in the industrial field.
