    Product Description

    Tripropylene Glycol CAS 24800-44-0 is a colorless, water-soluble, medium-viscosity glycol, also known as TPG or triglycol, with molecular formula C9H20O4, molecular weight about 192.25 and EINECS 246-466-0.

    Synonyms: TPG; [(1-methyl-1,2-ethanediyl)bis(oxy)]bispropanol; Triglycol; Polypropylene glycol 200; Tripropylene glycol mixture of isomers.

    CAS: 24800-44-0.

    It has the molecular formula C9H20O4 and a molecular weight of about 192.25 g/mol.

    It appears as a colorless, hygroscopic liquid with low volatility and low toxicity.

    It has a higher boiling point and greater hydrophobicity than mono- or dipropylene glycol.

    It offers excellent solvent power for a wide range of organic compounds.

    It is a key intermediate for esterification with acrylic acid to produce tripropylene glycol diacrylate (TPGDA).

    A low-aldehyde, low-peroxide, low-moisture grade reduces color and side reactions during acrylate synthesis.

    It is used as a high-boiling solvent and coupling agent in printing inks, paints and latex coalescing systems.

    It is also used in hydraulic brake fluids, cutting oils, lubricants and textile or leather processing.

    Industrial grade suits general solvent and intermediate use, while UV grade is more tightly controlled for aldehyde, carbonyl, peroxide and color.

    Store in a cool, dry, well-ventilated area in tightly closed containers away from moisture and ignition sources.

    Protect from moisture and keep containers closed when not in use.

    Confirm appearance, purity, water content, aldehyde, acidity and color (APHA) as required.

    Use suitable eye and skin protection during handling, and wash skin contact with soap and water.

    Confirm packaging with the requested quantity and destination requirements.

    FAQ - Technical & Supply Chain

    • Q:

      What is Tripropylene Glycol CAS 24800-44-0?

      A: Tripropylene Glycol, or TPG, is a colorless, hygroscopic, water-soluble liquid with the formula C9H20O4 and molecular weight about 192.25 g/mol. It is supplied as a mixture of isomers produced by the hydration of propylene oxide.
    • Q:

      How does Tripropylene Glycol differ from Propylene Glycol and Dipropylene Glycol?

      A: TPG has a higher molecular weight, higher boiling range around 265-275 degrees C, lower volatility, and higher viscosity than MPG or DPG. These properties make it more suitable for high-temperature fluids and for building longer-chain acrylates such as TPGDA.
    • Q:

      Why is Tripropylene Glycol the main raw material for TPGDA in UV-curable systems?

      A: TPG is esterified with acrylic acid to produce tripropylene glycol diacrylate, a widely used reactive diluent. A low-aldehyde, low-peroxide, low-moisture TPG grade reduces color, side reactions, and instability during acrylate synthesis and in the final UV coating or ink.
    • Q:

      What is the difference between industrial grade and UV grade Tripropylene Glycol?

      A: Industrial grade is suitable for general solvent, coupling, lubricant, and intermediate use. UV or acrylate grade is monitored more tightly for aldehyde, carbonyl, peroxide, moisture, acidity, and APHA color because those impurities can affect TPGDA synthesis and clear-coat quality.
    • Q:

      What are the main applications of Tripropylene Glycol besides TPGDA?

      A: TPG is used as a high-boiling solvent and coupling agent in printing inks, paints, and latex coalescing systems; as a base component in hydraulic brake fluids; in cutting oils and lubricants; and as a textile or leather processing aid.
