Glycol

Glycol

Glycol is a class of organic compounds with varying length carbon chains with two hydroxyl (–OH) groups. Two common glycol compounds are: ethylene glycol and propylene glycol. Ethylene glycol is mainly used in antifreeze, and for the manufacturing of polyesters. Propylene glycol is also used for the production of polymers, and because it is non-toxic it is used in food, pharmaceutical, and cosmetics applications.

Hanna Instruments offers digital refractometers for ethylene and propylene glycol analysis, and a titration based chemical test kit for measuring the presence or absence of glycol in a sample.
