'''Polyethylene glycol cetyl ether''' ('''polyethylene glycol hexadecyl ether''') is a nonionic surfactant produced by the ethoxylation of cetyl alcohol to give a material with the general formula HO(C<sub>2</sub>H<sub>4</sub>O)<sub>''n''</sub>C<sub>16</sub>H<sub>33</sub>. Several grades of this material are available depending on the level of ethoxylation performed, with repeat units (''n'') of polyethylene glycol varying between 2 and 20. Commercially it can be known as Cetomacrogol 1000, Brij 58 (when ''n''=20), Brij 56 (when ''n''=10), and other trade names.
It is used as a solubilizer and emulsifying agent in foods, cosmetics, and pharmaceuticals, often as an ointment base.<ref>{{cite web | url = https://www.cancer.gov/publications/dictionaries/cancer-drug/def/polyethylene-glycol-1000-cetyl-ether-cream | title = Polyethylene glycol 1000 cetyl ether cream | work = NCI Drug Dictionary | publisher = National Cancer Institute }}</ref> It is used as an oil in water (O/W) emulsifier for creams/lotions, and a wetting agent.
