Cetomacrogol 1000 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. If n=20 it is named Brij58. If n=10, it is named Brij56. It is used as a solubilizer and emulsifying agent in foods, cosmetics, and pharmaceuticals, often as an ointment base, and also as a research tool. It is used as O/W emulsifier for creams/lotions; Wetting agent in sticks; Conforms to BP specifications. Use 0.5-5%.
