Diethylene Glycol Monobutyl Ether, commonly referred to as DB or Butyl Carbitol, is a slow-evaporating, hydrophilic glycol ether with the chemical formula C₈H₁₈O₃ and CAS number 112-34-5. It is registered under EINECS number 203-961-6 and classified under HS code 2909430000.
DB can be considered a slower-evaporating analog of ethylene glycol monobutyl ether (Butyl Cellosolve). It offers complete water solubility, which distinguishes it from more hydrophobic glycol ethers and supports its use in formulations where compatibility with aqueous systems is required. The product appears as a colorless transparent liquid and is supplied at a minimum purity of 99.5% in industrial grade.
The combination of water solubility, coalescing power, and coupling capability makes DB a versatile solvent across coatings, cleaners, inks, and metalworking applications.

DB functions as a coalescent in water-based architectural and industrial coatings, supporting the formation of continuous, uniform films from latex polymer dispersions. Its water solubility allows it to distribute within the aqueous phase of coating formulations, while its solvency for polymer resins enables it to soften latex particles during film formation.
In latex adhesives, DB also serves as a coalescent, contributing to the formation of flexible adhesive films with good substrate wetting. The product's slow evaporation rate supports extended open time in both coating and adhesive formulations.
DB acts as a coupling agent and solvent in a range of cleaning formulations, including household and industrial cleaners, rust removers, hard surface cleaners, and disinfectants. Its ability to couple aqueous and organic phases supports the formulation of stable, single-phase cleaning products that combine water-soluble and oil-soluble active ingredients.
In hard surface cleaners, DB contributes to soil removal by dissolving greasy and oily residues. Its coupling properties also help maintain product clarity and stability across temperature variations.
DB serves as a primary solvent in solvent-based silk screen printing inks, where its solvency for a range of resins and its controlled evaporation rate support ink performance. In water-based printing inks, it functions as a coupling solvent for resins and dyes, helping to maintain formulation stability and color uniformity.
The product is also used as a solvent for ball point and felt tip pen inks, as well as in textile dyeing and printing applications where its solvency and coupling properties support dye dispersion and penetration.
In metalworking applications, DB is used as a component in metalworking fluids, where it contributes to formulation stability and can serve as a coupling agent for various additives. Its low volatility and water solubility make it suitable for use in water-based metalworking fluid concentrates.
DB is available in multiple packaging formats to accommodate different commercial procurement scales. Standard packaging options include iron drums, intermediate bulk containers (IBC), and ISO tank containers for bulk shipments. The minimum order quantity is typically one metric ton.
For storage, DB should be kept in a cool, dry, well-ventilated warehouse area away from heat sources and open flames. With a flash point of 114°C (Setaflash Closed Cup), DB is classified as a combustible liquid, and appropriate fire safety precautions should be observed. Containers should be tightly sealed when not in use to prevent contamination and moisture absorption.
Personnel handling DB should follow standard industrial hygiene practices, including the use of appropriate personal protective equipment such as chemical-resistant gloves and eye protection. Work areas should have adequate ventilation to maintain vapor concentrations below applicable occupational exposure limits.
The CAS number of Diethylene Glycol Monobutyl Ether (DB / Butyl Carbitol) is 112-34-5. It is also registered under EINECS number 203-961-6.
DB is used as a coalescent in water-based coatings and latex adhesives, as a coupling agent and solvent in industrial and household cleaners, as a solvent in printing inks and textile dyeing, and as a component in metalworking fluids.
Yes, DB is fully soluble in water. This hydrophilic property distinguishes it from more hydrophobic glycol ethers and supports its use in water-based formulations where complete miscibility with the aqueous phase is required.
The boiling point of DB is 230°C (446°F) at 760 mmHg (1.01 bar). Its evaporation rate is less than 0.01 relative to n-butyl acetate (1.0), making it a slow-evaporating glycol ether suitable for applications requiring longer open time.
Industrial grade DB is supplied at a minimum purity of 99.5%. The product appears as a colorless transparent liquid and is manufactured to meet industrial formulation requirements across coatings, cleaning, ink, and metalworking applications.
