Description
Polyethylene Glycol Product Overview
Polyethylene glycols are polymers of ethylene oxide. Their name includes the average molecular weight, for example PEG 400 or PEG 4000. Grades up to about PEG 600 are clear liquids, while higher grades are white waxy solids, flakes or powders. All dissolve in water and have low volatility.
Pharmaceutical companies use PEG as an ointment and suppository base, a solvent for liquid formulations, and a binder and coating component in tablets. Cosmetic formulators use it as a humectant and solvent, and PEG serves as the starting material for many PEG esters and ethoxylated ingredients. In these roles it often appears next to Glycerine and 1,2-Propylene glycol.
In industry, PEG works as a lubricant, mold release agent, binder in ceramics and dispersant in paints and inks. Choosing the right grade matters, because molecular weight controls viscosity, melting point and solubility.
