PEG - 300 (Polyethylene Glycol 300)

PEG-300 (Polyethylene Glycol 300) is a medium molecular weight form of polyethylene glycol. It is a clear, colorless, odorless, and viscous liquid with a slightly syrupy consistency. The "300" refers to its average molecular weight of approximately 300 g/mol, making it slightly heavier than PEG-200 but still a relatively low molecular weight polymer. PEG-300 is highly soluble in water and alcohols, and it has a wide range of industrial and pharmaceutical applications.
In the pharmaceutical industry, PEG-300 is used as a solvent, emulsifier, and plasticizer in the formulation of topical creams, ointments, and oral liquid preparations. It helps improve the texture, stability, and bioavailability of active ingredients. In the cosmetic industry, PEG-300 is used in skin creams, lotions, and shampoos due to its ability to provide moisture and improve the spreadability of products. It also finds use as a lubricant and plasticizer in industrial applications such as paints, inks, and coatings.
