Tripropyleneglycol 90% is a colorless liquid, slightly viscous, with a faint, subtle odor. In chemical terms, it belongs to the glycol family and stands as a mixture of tripropylene glycol isomers. Industry professionals encounter it in applications that range from solvents to intermediates for chemical manufacturing. With an HS Code of 2905399090, global trade identifies it as a commodity with established industrial value.
This compound holds the molecular formula C9H20O4. Its structure consists of three propylene oxide units connected by ether linkages, terminating with hydroxyl groups. The arrangement of these groups bears real weight on how the material interacts in different settings. Molecular weight sits near 192.25 g/mol, reflecting the balance between carbon, hydrogen, and oxygen atoms that shape both its reactivity and compatibility.
Most of the time, Tripropyleneglycol 90% appears as a clear or slightly pale liquid at room temperature. It rarely shows up as flakes, powder, pearls, or crystal because its characteristic form under typical handling conditions is consistently liquid. The density hovers around 1.01 to 1.02 g/cm3 (20°C), which places it near water, though it pours thicker, hinting at that higher viscosity so familiar during pouring and measuring. This property matters for anyone dealing with pumps, transfer lines, or blending—a slow stream saves spills, but can challenge fast-scale production.
Tripropyleneglycol 90% stands for a solution that contains not less than 90% tripropylene glycol isomers by weight. Water content remains low, often less than 1%, with lighter contaminants tightly controlled across reputable suppliers. Boiling point reaches up past 275°C, while the material starts to break down when pushed above 300°C, demanding respect in high-heat environments. Flash point rises above 138°C (closed cup), far safer than lower-molecular-weight glycols, which gives working teams more breathing room in facilities where open flames or heat are part of the process.
Tripropyleneglycol 90% qualifies as a raw material that rarely poses acute hazards at standard working exposures. Skin contact can sometimes cause mild irritation after prolonged handling. Eye contact may bring discomfort but not lasting harm if washed quickly. The vapor pressure remains low enough that significant inhalation risk tends to stay out of routine operation; open vats do not send harsh clouds across production floors. Even though this chemical is not classified as hazardous for transport or storage, spill control and cleanup keep risks down—not just for chemical health, but also to limit slip hazards underfoot.
Storage for Tripropyleneglycol 90% works best in tightly sealed, corrosion-resistant containers in cool, dry places. Pumps and pipelines should use materials compatible with glycols to avoid slow leaks and breakdowns. Keeping the product from strong acids, oxidizers, and open flames eliminates many headaches down the road. Spillage rarely leads to widespread harm, but a proper material safety data sheet (MSDS) in the hands of every handler means small mistakes stay small. For transport, standard drums or intermediate bulk containers keep things safe, with clear labeling based on the HS Code to smooth passage through customs and compliance checks.
People who work on the factory floor with tripropyleneglycol learn early on that the material rarely disrupts the daily flow of operations, so long as basic safety routines get honored. As a glycol, waste management plans focus on controlled discharge and neutralization—sewage systems and open waterways should never receive waste streams containing high levels of this chemical, not because of acute toxicity, but to prevent slow, accumulative shifts in biological oxygen demand. Over time, responsible use lines up with regulatory compliance and healthy local environments.
In dozens of industries, tripropyleneglycol 90% supports production as a solvent, plasticizer, intermediate, and heat transfer fluid. Paints, inks, resins, and coatings rely on it for its balance of solvency power and manageable evaporation rate. In deicing agents, it pulls its weight against freezing without the biting, skin-chapping harshness seen in stronger glycols. Because it lacks a strong, lingering odor and offers relatively low toxicity, workers find handling it more pleasant in prolonged use cases. The substance stands as a practical fit for manufacturers aiming to keep both efficiency and safety on the front burner.
Manufacturing plants face the ongoing question—how does one keep efficiency high while protecting worker health and the surrounding environment? Tripropyleneglycol 90% provides a real-world answer in part: manageable hazard profile, good chemical stability, and versatile utility ease pressure points. Plant managers strengthen safety cultures with regular training, clear labels, and readiness to handle spills or direct exposures, cutting down on preventable incidents. At the industry level, ongoing review of environmental discharge practices and raw material sourcing offers a long-term play for sustainability. Transparency from suppliers about exact specifications and impurity profiles supports informed decision-making for everyone down the value chain—from chemists through maintenance to warehouse teams.
Tripropyleneglycol 90% features a molecular formula of C9H20O4, presents most often as a transparent, slightly viscous liquid, and holds steady at densities near 1.01–1.02 g/cm3. Safe practices keep handling low-risk; the substance rarely behaves in hazardous ways during standard use, storage, or transport. Responsible selection, environmental stewardship, and transparent communication round out its place among key industrial raw materials. Reliable supply hinges not on speculation, but on a grounded approach to chemical knowledge, practical handling, and up-to-date safety training across the modern production landscape.
