Polyethylene glycol (PEG) is a versatile chemical compound widely used across various industries. The CAS number for Polyethylene glycol is 25322-68-3. This text details the physical properties of PEG and explores three to four different applications.

Physical Properties

Polyethylene glycol exists as a water-soluble, clear, colorless to slightly yellowish liquid or a solid, waxy material, which can exhibit different consistencies depending on its molecular weight. It is highly soluble in water and most organic solvents and possesses high hygroscopicity (water-attracting ability). The molecular weight of Polyethylene glycol typically ranges from a few hundred to over 10,000 g/mol. PEG can range in consistency from flaky to waxy.

Applications of Polyethylene Glycol

Polyethylene glycol is extensively used in the pharmaceutical industry as an excipient to improve the stability and solubility of drugs. It is employed in the manufacturing of tablets, capsules, ointments, and injectable solutions. PEG is notably used as a carrier in drug delivery systems due to its ability to control drug release.

In cosmetics, Polyethylene glycol is utilized in various products including creams, lotions, shampoos, and toothpastes. It acts as a humectant and emulsifier, helping to regulate the viscosity of products and ensuring even distribution of ingredients.

The chemical industry employs Polyethylene glycol as a solvent, reaction medium, and starting material for the synthesis of other chemical compounds. Its versatility and compatibility with many other chemicals make PEG indispensable in numerous processes.

In the food industry, Polyethylene glycol is used as a food additive (E1521), particularly as an emulsifier and stabilizer. It contributes to improving the texture and consistency of food products and is commonly found in baked goods, confectionery, and ice cream.

Polyethylene glycol (PEG) (CAS No. 25322-68-3) is an incredibly versatile chemical compound with broad applications in pharmaceuticals, cosmetics, chemicals, and the food industry. Its physical properties make it a valuable excipient that enhances the stability, solubility, and applicability of many products.
