Luna-fax PEG 600 DO is a non-ionic surfactant produced by esterification of oleic acid with polyethylene glycol (PEG 600). As a di-ester, it provides enhanced hydrophobic character and lubricity compared to mono-esters, making it particularly effective in water-in-oil (W/O) and oil-rich systems, as well as in lubrication and textile applications. Luna-fax PEG 600 DO is widely used in industrial formulations where emulsification, lubrication, and antistatic properties are required.
