POLYETHYLENE GLYCOL Chemical compatibility with O-rings, rubbers, & plastics

Polyethylene glycol (PEG) is a versatile polymer with the chemical formula HO(CH2CH2O)nH, where n indicates the number of repeating units. PEGs are available in various molecular weights, ranging from liquids to solids. They are widely used in pharmaceuticals, cosmetics, and industrial applications. In pharmaceuticals, PEGs serve as solvents, excipients, and drug delivery agents. In cosmetics, they act as moisturizers, thickeners, and emulsifiers. Industrially, PEGs are used as lubricants, anti-foaming agents, and in the manufacture of resins and plastics. PEGs are generally regarded as safe, but prolonged exposure or ingestion can cause irritation and other health issues. Proper handling includes the use of protective gloves and goggles. Storage should be in tightly sealed containers to prevent moisture absorption. Disposal should follow local regulations to prevent environmental contamination. PEGs are valued for their solubility, versatility, and low toxicity in a wide range of applications.
