Descripción

Descripción general

Polyethylene glycol (PEG) is a polymer of ethylene oxide and water, obtained upon condensation. PEGs are susceptible to oxidative degradation in the presence of air. Minimizing the exposure of PEG to elevated temperatures and/or exposure to oxygen or addition of an antioxidant can limit the amount of degradation. PEGs do not hydrolyze or deteriorate upon storage. PEGs do not support the growth of molds.

Polyethylene glycol (PEG) is used in detergents, emulsifying agents, soaps, metal costing process, pharmaceutical preparations and cosmetics. PEG is commonly used as a lubricant. It′s application is also observed in chromatographic stationary phases. PEG prevents crystal formation in emulsions.

Aplicación

Poly(ethylene glycol) has been used:

• in protoplast suspension
• to prevent phase separation in emulsion
• in phage tail-like particles precipitation
• for purifying and intensifying products of polymerase chain reaction
