Tripropylene Glycol Monomethyl Ether, commonly referred to as TPM, is a high-boiling glycol ether with the molecular formula C10H22O4 and CAS number 25498-49-1. Its EINECS number is 247-045-4. TPM is a mixture of isomers formed through the addition of three propylene oxide units to methanol, resulting in a colorless liquid with a mild ether odor.
As the heaviest member of the propylene glycol monomethyl ether series, TPM features a higher molecular weight and boiling point compared to PM (mono) and DPM (di). Its extended propylene oxide chain provides increased hydrophobic character while retaining water miscibility. This balance of properties makes TPM suitable for applications requiring slow evaporation and strong coupling performance, such as high-solids coatings and industrial cleaning formulations.

TPM serves as a solvent for stamp pad inks, ballpoint pen inks, and felt-tip pen formulations. Its low evaporation rate helps maintain consistent rheological properties over time, preventing ink from drying in reservoirs or on nibs. Industrial clients in the writing instrument industry use TPM to extend the working life of ink formulations and improve color transfer performance.
In paint stripping and rust removal formulations, TPM functions as both a coupling agent and a solvent. Its high boiling point allows extended contact time on vertical surfaces, supporting the penetration and softening of cured coatings. Business buyers in the surface treatment sector incorporate TPM into heavy-duty paint removers and rust dissolvers.
TPM acts as a coupling agent and co-solvent in industrial hard surface cleaners, where it helps dissolve both aqueous and oily soils. Its slow evaporation rate provides extended dwell time for effective cleaning. In penetrating oil formulations, TPM supports the penetration of active ingredients into tight spaces for rust loosening and lubrication.
TPM functions as a mutual solvent, coupling agent, and emollient in certain cosmetic formulations. Its solvency properties help incorporate fragrance oils and active ingredients into water-based products. Enterprise customers in the personal care industry use TPM in products where mildness and solvency are both required.
In agricultural chemical formulations, TPM serves as a stabilizer and co-solvent for herbicide concentrates. Its low volatility and high boiling point support formulation stability during storage and application.
As a tailing solvent in high-solids, solvent-based coating systems, TPM contributes to controlled film formation and flow leveling. Its slow evaporation rate helps prevent surface defects such as blistering or pinholing in oven-cured coatings.
TPM is available in multiple packaging configurations: 200 kg iron drums, 1000 L IBC totes, and ISO tank containers for bulk supply. The minimum order quantity is 1 metric ton. The HS Code for customs classification is 2909499090.
Storage should occur in a cool, dry, well-ventilated area away from strong oxidizing agents and direct sunlight. Containers must remain tightly sealed when not in use. Due to its high flash point (124°C), TPM presents a lower flammability hazard compared to lighter glycol ethers, but standard industrial chemical handling procedures still apply.
Transportation follows standard regulations for industrial chemical liquids. Bulk shipments by sea or road require appropriate UN classification and labeling per applicable transport regulations.
Industrial-grade TPM is manufactured with a minimum purity of 98.5%, determined by gas chromatography. Each batch accompanies a Certificate of Analysis (COA) detailing purity, water content, acidity, color (APHA), and density measurements.
The product complies with standard industrial chemical specifications. For commercial users requiring specific regulatory compliance documentation, including REACH registration details or SDS documents, these can be provided upon request. Customized purity specifications for specialized applications are available through consultation with the technical team.
TPM (tripropylene glycol methyl ether) has three propylene oxide units, compared to one in PM and two in DPM. This results in a higher molecular weight (206.3 vs 90.1 g/mol), higher boiling point (243°C vs 120°C), lower vapor pressure, and a slower evaporation rate. TPM is chosen when extended residence time and higher boiling characteristics are needed.
Yes, TPM is completely miscible with water at 20°C. It also shows compatibility with most organic solvents, including alcohols, ketones, esters, and aromatic hydrocarbons.
Standard industrial-grade TPM has a minimum purity of 98.5% as measured by GC. The product is a mixture of isomers, which is normal for tripropylene glycol derivatives. Higher purity grades can be arranged for specialized applications.
TPM is supplied in 200 kg iron drums, 1000 L IBC totes, and ISO tank containers for bulk orders. The minimum order quantity is 1 metric ton. Custom packaging requirements can be discussed for large-volume orders.
Standard lead time is 7 - 15 working days from order confirmation for drum and IBC quantities. Bulk ISO tank shipments may require 15 - 25 working days depending on the destination and scheduling.
Yes, sample quantities are available for evaluation purposes. Please contact the sales team to request samples along with the corresponding COA and SDS documents for quality assessment prior to commercial procurement.
