Usage And Synthesis

Description

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).

Uses

Polyethylene glycol hexadecyl ether is used as a surface active agent in cosmetics. Polyethylene glycol hexadecyl ether is a compound of derivatives of cetyl, lauryl, stearyl, and oleyl alcohols mixed with ethylene oxide.Non-ionic surfactant of the polyethylene glycol family. Polyethylene glycol hexadecyl ether is used as a solubilizer and emulsifying agent in foods, cosmetics, and pharmaceuticals, often as an ointment base, and also as a research tool. Polyethylene glycol hexadecyl ether is used as an oil in water (O/W) emulsifier for creams/lotions, and a wetting agent.

Chemical Properties

off-white waxy solid

Uses

Polyethylene glycol hexadecyl ether, or Brij 58, has been used in a study to assess properties of gemini-conventional surfactant mixtures and their effects on solubilization of polycyclic aromatic hydrocarbons. It has also been used in a study to investigate RNase-sensitive constraint of bacterial nucleoid structure.

Uses

Brij C10 is a surfactant that can be used for applications such as: improving the wetting of PEDOT:PSS which can further be used in the fabrication of thin film transistors, formation of reverse micelles for the synthesis of high yielding nanostructures, in the preparation of platinum electrode for fuel cell applications

Uses

ceteth is used as a surface active agent in cosmetics. It is a compound of derivatives of cetyl, lauryl, stearyl, and oleyl alcohols mixed with ethylene oxide.

General Description

Brij 58 is a nonionic surfactant or detergent for protein extraction and permeabilization of cells. It may be used in the preparation of yeast spheroplasts.

Flammability and Explosibility
