The core chemical component of tristyrylphenol ethoxylate 600-2 (600#-2) and 600-1 (600#-1) is tristyrylphenol ethoxylate. It is a nonionic surfactant prepared by addition polymerization of ethylene oxide (EO) using tristyrylphenol as the hydrophobic group (lipophilic end). The difference between 600-2 and 600-1 lies in the number of ethylene oxide adducts, thereby adjusting the hydrophilic-lipophilic balance (HLB) range to meet different application requirements.
