Tripropylene glycol is a colorless, slightly viscous liquid.

??

Tripropylene glycol is made commercially as a by-product of propylene glycol production. It is used much as the other glycols as an intermediate in the production of ethers, esters, and resins; as a nonvolatile solvent; and as a polyester humectant and a plasticizer. It is not used in drugs, pharmaceuticals, or food applications because its toxicological properties have not been clearly defined. Industrial exposure is limited almost entirely to direct contact with the liquid. Vapors or mists may be encountered under unusual conditions.
