Tripropylene Glycol Regular Grade (TPG) is a versatile chemical intermediate and solvent used in a variety of application areas. It 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, high solvent power, low volatility and high boiling point make it a material of choice for textile soaps and lubricants, cutting-oil concentrates and other 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.
