Polyethylene Glycol Monocetyl Ether(Cetomacrogol 1000) is off-white waxy solid. Polyethylene Glycol Monocetyl Ether is the tradename for polyethylene glycol hexadecyl ether , which is nonionic surfactant produced by the ethoxylation of cetyl alcohol to give a material with the general formula HO(C2H4O)nC16H33. Several grades of this material are available depending of the level of ethoxylation performed, with repeat units (n) of polyethylene glycol varying between 2 and 20. Commercially it can be known as Brij 58 (when n=20) or Brij 56 (when n=10).
