Propylene Glycols

Tripropylene Glycol Regular Grade (TPG)

Tripropylene Glycol Regular Grade (TPG) is typically used as an initiator for urethane polyol synthesis from epoxides and as the polyol in some polyurethane foam systems. TPG from Dow is an excellent solvent in applications where high solvent power is needed. Its water solubility, solvent power, low volatility and high boiling point make it a material of choice for textile soaps and lubricants, cutting-oil concentrates and many similar products. TPG is also used as an initiator for urethane polyols.

Many ink removal creams use TPG as part of their formulation, taking advantage of its ability to dissolve inks. In personal care applications, the low toxicity, non-irritating nature, solvency and compatibilizing power of TPG are important characteristics in applications such as stick deodorants.

TPG is available from Dow in drum and bulk quantities.
