Uses and Applications Of PEG 400
PEG 400 is a versatile substance with a wide range of uses across multiple industries:
Pharmaceuticals:
It’s a common inactive ingredient or excipient in drug formulations. Its main role is to act as a solvent to dissolve poorly water-soluble drugs, enhancing their solubility and bioavailability. It’s also used in topical creams, ointments, and eye drops for lubrication and to provide temporary relief from dry eyes.
Cosmetics and Personal Care:
It functions as a humectant (retains moisture), solvent, and emulsifier in products like lotions, creams, and soaps.
Its ability to attract and hold water makes it great for moisturizing the skin.
Industrial Applications:
Due to its lubricating and non-volatile properties, it’s used as a lubricant in various processes, a plasticizer in plastics, and a solvent for inks and dyes.
Food Industry:
PEG 400 is also approved as a food additive, functioning as an anti-foaming agent and a carrier for flavors.
