Polyethylene glycol 300 (PEG 300) is a water-miscible polyether with an average molecular weight of 300 g/mol. It is a clear viscous liquid at room temperature with non-volatile, stable properties . Polyethylene glycols are widely used in biochemistry, structural biology, and medicine in addition to pharmaceutical and chemical industries. They serve as solubilizers, excipients, lubricants, and chemical reagents. Low molecular weight glycols are observed to exhibit antibacterial properties as well. PEG 300 is found in eye drops as a lubricant to temporarily relieve redness, burning and irritation of the eyes.

Due to their physical properties, PEG acts as a surfactant by coating the eye. It provides lubrication and surface protection in dry eyes.
Indicated as a lubricant in over-the-counter ophthalmic solutions to temporarily relieve redness, burning and irritation of the eyes.
