Polyethylene glycol is abbreviated as "PEG". It is a high molecular compound formed by intermolecular dehydration and condensation of ethylene glycol. Due to its many excellent properties: water solubility, non-volatility, physiological inertness, mildness, lubricity, and the ability to moisturize skin, provide softness, and a pleasant after-feel, polyethylene glycol can be selected in different relative molecular weight grades to adjust the viscosity, moisture absorption, and structure of products. Low molecular weight polyethylene glycol 200 is suitable as a wetting agent and consistency regulator, used in creams, lotions, toothpaste, and shaving cream, and is also suitable for non-rinse hair care products, giving hair a silky shine.

Product Functional Category and Applications
Polyethylene glycol 200 (industrial grade PEG 200) can be used in the synthesis of polymers, resins, and coatings. In oil fields and petroleum exploration, industrial grade polyethylene glycol 200 (industrial grade PEG 200) can be used as a thickener and fluid transfer medium.

Under normal conditions, polyethylene glycol is very stable, but at 120°C or higher temperatures, it can react with oxygen in the air. In an inert atmosphere (such as nitrogen and carbon dioxide), it remains unchanged even when heated to 200–240°C. When the temperature rises to 300°C, thermal decomposition occurs. Adding antioxidants, such as 0.25%–0.5% phenothiazine by mass, can improve its chemical stability. Any decomposition products are volatile and do not form hard crusts or sludgy precipitates.
