Triethylene Glycol Monobutyl Ether (BTG), also referred to as Butoxytriglycol or Triethylene Glycol Butyl Ether, is a glycol ether compound with the molecular formula C10H22O4 and CAS number 143-22-6. It is a colourless transparent liquid with low volatility and relatively high solvency power. BTG exhibits good water solubility and coupling ability, making it suitable for a range of aqueous and semi-aqueous formulation systems.
As a higher molecular weight glycol ether compared with monoethylene and diethylene glycol butyl ethers, BTG offers a higher boiling point and lower vapor pressure. These properties make it a candidate for applications where reduced emissions and extended processing time are desired. Industrial clients in the coatings, textile, cleaning, and chemical manufacturing sectors commonly use BTG as a carrier solvent, coupling agent, or process additive.

BTG is supplied in industrial grade with a minimum purity of 98.0% as measured by gas chromatography. The remaining fraction consists primarily of related glycol ether homologues from the manufacturing process. Buyers with specific purity requirements for regulated applications should discuss these needs before placing an order.
BTG is used in waterborne coating and ink formulations as a coalescing aid and flow control agent. Its high boiling point and low volatility contribute to extended open time and improved film formation in latex-based coatings. In water-based printing inks, it functions as a coupling agent for resins and dyes, helping to maintain formulation stability and uniform colour development during the printing process.
In the textile industry, BTG serves as a carrier solvent in certain dyeing processes. Its high solvency for dye compounds, combined with low volatility, allows it to remain in the dye bath longer during high-temperature processing, which can support more uniform dye uptake on fiber surfaces. It is used in formulations for both natural and synthetic fiber treatment applications.
BTG's coupling ability and surface active properties make it a component in various household, institutional, and industrial cleaning product formulations. It helps solubilize oily soils and organic residues, and it can improve the shelf stability of cleaner formulations containing both aqueous and oily components. It is also found in some paint stripper and floor polish remover formulations.
In chemical manufacturing, BTG can serve as a process solvent and as an intermediate in the production of certain ester derivatives used as surfactants, plasticizers, and other specialty chemicals. Additionally, it is a component in some high-boiling point hydraulic brake fluid formulations where its high boiling point and low freezing point contribute to the fluid's performance across temperature ranges.
BTG is offered in standard industrial packaging options:
Steel drums: 200 kg net weight per drum
Intermediate Bulk Containers (IBC): 1,000 kg net weight per tote
ISO tank containers: For full bulk supply arrangements
All packaging meets applicable transportation regulations for chemical liquids. Enterprise customers with regular supply needs may arrange for dedicated inventory or consignment stock programs.
BTG should be stored in sealed containers in a cool, dry, well-ventilated storage area. It has a relatively high flash point, but standard precautions against ignition sources should still be observed. Personnel handling the product should wear chemical-resistant gloves, eye protection, and appropriate clothing. A full Safety Data Sheet (SDS) is available and should be reviewed before handling, storage, or use of this product.
The standard minimum order quantity is 1 metric ton, supplied in drum packaging. Larger volume orders in IBC totes or ISO tank containers are also available. Sample quantities for formulation evaluation can be requested separately; please contact the sales team for current sample availability.
BTG (Triethylene Glycol Monobutyl Ether) has one more ethylene oxide unit than DBG (Diethylene Glycol Monobutyl Ether), resulting in a higher molecular weight, higher boiling point, lower volatility, and generally greater water solubility. The choice between them depends on the specific application requirements for evaporation rate, solvency strength, and volatility profile.
Standard delivery lead time is 7 to 15 working days after order confirmation, depending on order volume and current stock levels. Bulk ISO tank shipments may require additional logistics coordination time. For urgent requirements, please contact the sales team to discuss expedited options.
BTG supplied in standard industrial grade is intended for industrial use only. It is not recommended for food-contact, pharmaceutical, or cosmetic applications without specific grade verification and regulatory assessment. Buyers requiring materials for regulated industries should inquire about available grades and relevant documentation.
