Diethylene glycol CAS#111-46-6
Product Details
Diethylene glycol CAS#111-46-6
Diethylene glycol is a colorless, water-miscible liquid with a density greater than that of water. Direct contact with this substance may cause mild irritation to the skin, ocular tissue, and mucosal membranes. It exhibits low acute oral toxicity in humans and is primarily utilized as a key intermediate in the synthesis of a broad range of specialty chemicals..

Product Application of Diethylene glycol CAS#111-46-6
Diethylene glycol (DEG) is a widely employed industrial solvent and formulation component across diverse commercial sectors. Its applications span multiple industries: it acts as a dehydration agent in natural gas treatment processes; functions as a lubricant and finishing additive for textile materials; serves as a key ingredient in brake fluids, lubricants, antifreeze preparations, wallpaper removers, and artificial fog mixtures; works as a solvent for printing inks and textile colorants; and acts as a core intermediate in the synthesis of specialized resins, triethylene glycol, surfactants, as well as diethylene glycol esters and ethers.
