Glykolien

Glykolien refers to glycols, dihydric alcohols with two hydroxyl groups. They are polar, usually liquids or solids at room temperature, and soluble in water.

Common examples include ethylene glycol and propylene glycol; higher diols such as butanediols exist. Their chemistry enables use as solvents and as reactive components in polymers.

Main uses include antifreeze/coolants, solvents in paints, cosmetics, pharmaceuticals, and humectants in food and personal care; also as monomers for polyesters and polyurethanes.

Health and safety: Ethylene glycol is highly toxic if ingested, causing kidney damage; propylene glycol has lower acute toxicity and is widely used in foods and medicines. Environmental fate: glycols are generally biodegradable but spills can affect aquatic systems.

Regulation and handling: Glykolien are typically managed with standard chemical safety protocols, including safety data sheets and personal protective equipment.
