Polyethylene oxide and polyethylene glycol are both polymers made of repeating ethylene glycol units. The main difference between them is their molecular weight. Polyethylene oxide has a lower molecular weight and is a liquid at room temperature, while polyethylene glycol has a higher molecular weight and is a solid or semi-solid at room temperature. Additionally, polyethylene glycol is commonly used in pharmaceuticals and cosmetics, while polyethylene oxide is used in industrial applications.
