Propylene glycol phenyl ether acetate stands as a well-established chemical, formulated by combining a propylene glycol backbone with phenyl ether and an acetate group. Its formula, C11H14O3, outlines a balanced composition, giving it both practical solvent features and valuable chemical stability. Recognizing this compound under its HS Code — typically 291539 — helps move it easily across international borders, supporting global commerce for those in coatings, adhesives, or specialty chemical industries. Each batch enters the market as a liquid at standard room temperatures, but it displays fascinating transitions under different conditions, sometimes seen as flakes or crystals if cooled or exposed to the right catalysts.
In terms of appearance, purity, and reliability, this material explains itself well. The clear, colorless liquid signals minimal contamination and immediate solubility in a range of organic carriers. Specific gravity ranges from 1.12 to 1.14 at 25°C, which can be tested easily in the lab. Its density and viscosity suit it to jobs where slow evaporation creates better film formation or stable blending, such as in high-performance coatings or specialty inks. Hydrophobic characteristics make it poorly miscible in water, while the ether and ester functionalities set it apart for dissolving resins and polymers that resist traditional solvents. At a glance under a microscope, its molecular structure reveals a flexible, stable architecture designed for compatibility rather than volatility.
Manufacturers deliver this chemical primarily in liquid form, with a smooth viscosity that fits automated dispensing. Quality control ensures every liter measures up to spec, supporting repeatable results batch after batch. Cold storage or low-temperature handling encourages crystalline or flaky solids that dissolve gently with mild warming. Research labs often work with these forms to better control dosing or purity checks. Larger industrial customers sometimes order bulk flakes or even a powder format to fine-tune existing formulations.
Chemically, the C11H14O3 structure draws from propylene oxide and phenol-derived feedstocks. Acetylation rounds out the molecule, giving rise to its acetate function while leaving the ethereal oxygen for distinctive reactivity. Raw materials come from petrochemical flows but require purification every step of the way. I’ve seen quality drift in some batches when raw materials weren’t traceable, so sourcing from responsible suppliers matters both for product integrity and for safety in end uses.
Every technical data sheet starts with specifications for purity, color (APHA below 50 is preferred), water content (less than 0.1%), and acid value (max 0.05 mg KOH/g). Handling protocols insist on airtight storage to avoid hydrolysis. Many teams focus on stability, especially for ink or adhesive use, because hydrolysis can quickly generate off-odors or degrade performance. Material safety data shows flash point sitting near 120°C, discouraging reckless handling and requiring fire prevention measures in processing or storage.
The risks attached to propylene glycol phenyl ether acetate can’t be ignored. Human safety comes first, so goggles, gloves, and splash-proof gear become standard when pouring or mixing. Eye and skin contact bring mild irritation, which can escalate if not washed quickly with water. Solvent vapors in closed spaces demand proper ventilation: I always recommend fume extraction — long before the first drop reaches the beaker. While this acetate doesn’t match the acuteness of chlorinated solvents, long-term exposure still carries uncertainty. Chronic exposure, spills, and poor waste disposal lead to headaches, nausea, and, in high quantities, nervous system disturbances.
No one wants chemical waste leaching into groundwater or air. Teams handling propylene glycol phenyl ether acetate should adopt spill plans and containment procedures. Its breakdown products — after combustion or environmental exposure — can include low-level phenolic or acetic acid residues. Responsible use follows regional safety and disposal laws, starting with correct labelling and MSDS filings. European, US, and Asian regulations continue to evolve, measuring both occupational standards and residue allowances in finished goods.
Formulators turn to propylene glycol phenyl ether acetate when they need more than simple volatility. Ink manufacturers rely on its predictable drying curve and pigment-dispersing power. Coatings benefit from its balance of flow and leveling. As resin chemistries change, so must the solvent selection, and this compound fills a niche that polar and non-polar solvents both sometimes miss. Sometimes adding it to a formulation makes the difference between a sticky mess and a smooth finish. For all its utility, the long-term challenge revolves around reducing reliance on petroleum-based raw materials and minimizing environmental harm. Blending safer practice with continuing performance improvement points the way forward for end users, researchers, and manufacturers alike.
