What is propylene glycol? What are its functions?
Strictly speaking, propylene glycol includes two isomers, 1,2-propanediol and 1,3-propanediol, the latter of which is mainly used as a solvent in industry and production. Therefore, the commonly mentioned propylene glycol in daily life specifically refers to 1,2-propanediol.
Propylene glycol is an organic compound that is an almost odorless viscous liquid at room temperature. Its chemical properties are stable and it has a certain degree of water absorption. Its toxicity and irritancy are very low.
