Polyetyleuryyttejä

Polyetyleuryyttejä is a Finnish term that translates to "polyethylene glycols" in English. Polyethylene glycols (PEGs) are a family of linear polymers of ethylene oxide. They are produced by the polymerization of ethylene oxide and water. PEGs are characterized by their molecular weight, which can range from a few hundred to several million. They are non-ionic, water-soluble polymers that are widely used in various industrial, medical, and cosmetic applications.

In industrial settings, PEGs are employed as solvents, lubricants, and plasticizers. Their ability to dissolve a wide range of substances makes them useful in the production of detergents, inks, and dyes. In the pharmaceutical industry, PEGs are used as excipients in drug formulations, acting as binders, emulsifiers, and solubilizing agents. They are also used in the manufacturing of medical devices and as a component in laxatives.

In cosmetics and personal care products, PEGs serve as humectants, emollients, and emulsifiers. They help to retain moisture in the skin and hair and are found in products such as shampoos, lotions, and toothpaste. Due to their versatility and low toxicity, PEGs have become indispensable in many fields. The specific properties of a PEG, such as its viscosity and solubility, can be tailored by controlling its molecular weight and degree of polymerization.
