is propylene glycol nonionic
Propylene glycols are used as initiators for synthesis of nonionic surfactants made from polymerization of ethylene oxides with other oxides such as propylene or butylene oxides. Propylene glycol is also used as the starting material for the synthesis of propylene glycol esters with sorbitol and/or fatty acids.ust suppression. Dust formation and the associated housekeeping issues, plus the danger of dust explosions, make dust suppression important in mining and cement grinding applications.
