Description

Packaging

1 kg in poly bottle

2 kg in poly drum

500 g in poly bottle

Application

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

Biochem/physiol Actions

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.

General description

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.
