Propylene Glycol Diacetate, a colorless liquid with a mild odor, belongs to the ester family of organic chemicals. Chemically, it carries the formula C7H12O4 and features a molecular structure that links two acetate groups to a propylene glycol backbone. Folks in the chemical industry often refer to its HS Code 2915390090 during freight paperwork. This material stands out for its combination of solvency and low volatility, which makes it attractive for folks working in coatings, inks, and cleaning product formulations.
Looking closely, Propylene Glycol Diacetate's molecular composition affects how it interacts with other substances. Its molecular weight clocks in at about 160.17 g/mol. The chemical offers a density of around 1.08 g/cm3 at 20°C, which points to a modest heaviness when poured or measured by volume. It shows relatively low vapor pressure, meaning it doesn’t easily evaporate at room temperature, contributing to applications where drying too quickly proves problematic. Its melting point sits below freezing, so it stays a liquid in most climates where people store and use it. Water doesn't dissolve this substance well, but many common solvents handle it just fine.
On the shelf, Propylene Glycol Diacetate typically shows up as a clear liquid. You won’t often see it as flakes, solid, powder, pearls, or crystals because its melting and boiling properties favor liquid handling. Still, what matters is knowing how it behaves if spilled or mixed into solutions. In fluid form, it pours easily and mixes well with other solvents, so folks blending large batches rarely struggle. Product labels reflect this consistency, and most safety data sticks to how the liquid responds under pressure, temperature, or exposure to air.
Several industries rely on Propylene Glycol Diacetate for its unique role as a solvent and carrier. In paint and coating shops, it helps avoid premature drying and brush marks. Printing ink makers value its moderate evaporation speed, which allows for crisp transfer and vivid color development. When working with cleaning agents or chemical blends, its solvency aids in dissolving stubborn residues that water alone can’t handle. Certain adhesives and personal care products also count on its mild smell and low irritancy, allowing people to use the finished item safely and comfortably. These practical uses help countless businesses stay productive, keep products safe, and limit waste.
Handling chemicals like Propylene Glycol Diacetate requires solid safety procedures. According to internationally recognized chemical safety sheets, this material does not easily ignite, yet exposure to high heat or open flames poses a risk for fire. Direct skin contact or inhalation might lead to mild irritation, so gloves and proper ventilation prove wise in any workspace. Industrial users need to prevent spills or accidental discharges into water systems, as aquatic organisms may suffer if exposure happens in large amounts. Waste management professionals recommend collecting and disposing of any excess through regulated chemical waste channels.
Manufacturers and buyers pay close attention to the specific gravity, purity, and acidity levels of Propylene Glycol Diacetate. The density reads about 1.08 grams per cubic centimeter, measured at 20°C. The refractive index lands around 1.41. Purity levels typically exceed 98% for commercial or industrial supply, limiting unwanted byproducts in sensitive applications. Sometimes users want the viscosity or boiling point for technical calculations – those usually run at about 3.6 mPa·s and 210°C, respectively. Storage drums or shipping containers put this chemical in volumes by liter, usually from 200 liters for factories up to smaller 20-liter pails for labs and test runs.
Spending time in a laboratory and production plant, I got to see firsthand the impact of choosing the right material for each step. Propylene Glycol Diacetate made life easier for workers who looked for a solvent that didn’t overpower the room with fumes and didn’t evaporate so fast they had to rush through critical formulations. Clean-up felt straightforward since it left little sticky residue if handled right. I once watched a paint developer switch to Propylene Glycol Diacetate from another solvent, leading to better spread and less smudging, which brought fewer customer complaints. Simple upgrades like that keep operations efficient and safe for the crew on the floor.
Years of experience in chemical handling have shown that prevention works better than cure. For Propylene Glycol Diacetate, training and clear safety data sheets help new workers understand risks without fear or guesswork. Well-designed ventilation keeps air fresh while controlling airborne droplets. Installing spill kits and assigning clean-up responsibilities ensures nobody freezes up when a drum tips over. On the environmental side, switching from ordinary floor drains to chemical capture basins stopped accidental leaks from reaching the storm system, sparing headaches and possible fines. Regular waste collection by licensed contractors rounds out a system that respects people and planet.
The bottom line on Propylene Glycol Diacetate: no one should overlook the practical advantages or close their eyes to the needs for safe handling. Knowing a product’s density, chemical reactivity, and storage needs leads to better decisions in procurement, daily use, and waste disposal. Students, formulation chemists, safety managers, and business owners all benefit from a clear understanding of the tools and materials that keep modern industry rolling. Keeping up with regulations, product specifications, and environmental responsibilities protects workers, the environment, and anyone who counts on finished goods in daily life.
