Diethylene Glycol Monobutyl Ether Acetate, commonly known as DBA or Butyl Carbitol Acetate, is a high-boiling, slow-evaporating ester solvent with the chemical formula C₁₀H₂₀O₄ and CAS number 124-17-4. It is the acetate ester of diethylene glycol monobutyl ether and is registered under EINECS number 204-685-9.
DBA provides a balance of volatility, solvency, and water solubility that supports its use across multiple formulation types. Its ability to distribute between the aqueous and polymeric phases in waterborne systems contributes to both film formation and formulation stability. The product appears as a colorless transparent liquid and is classified under HS code 2915390090. It is supplied at a minimum purity of 99% in industrial grade.

DBA is frequently used as a coalescing solvent in waterborne architectural and industrial coatings. As a coalescent, it aids in the film formation process by temporarily softening latex polymer particles, allowing them to coalesce into a continuous film as water evaporates. The product's balance of volatility, solvency, and water solubility supports both film quality and formulation stability.
In architectural coatings, DBA promotes color development and touch-up properties, particularly under conditions of low temperature and high humidity where slower-evaporating solvents help maintain film integrity during the drying process. Its mild, nonresidual odor supports its use in interior latex coatings where low-odor performance is desired.
DBA serves as a slow-evaporation solvent in specialty printing ink formulations. Its high boiling point and controlled evaporation rate help regulate drying speed in ink systems, allowing sufficient time for ink transfer and leveling on various substrates. The solvent's solvency characteristics make it compatible with a range of resin systems used in ink manufacturing.
In agricultural formulations, DBA is used as a solvent in pesticide products. Its solvency properties support the dissolution and dispersion of active ingredients in pesticide concentrates. The product also finds application as a selective solvent in certain chemical separation processes, where its ability to dissolve specific alcohols and ketones is utilized in distillation-based separation techniques.
DBA is available in multiple packaging formats to suit different business operations requirements. Standard options include iron drums, intermediate bulk containers (IBC), and ISO tank containers for large-volume commercial procurement. The minimum order quantity is typically one metric ton.
Storage conditions should include a cool, dry, well-ventilated warehouse area away from heat sources, open flames, and direct sunlight. With a flash point of 105°C (Setaflash Closed Cup), DBA is classified as a combustible liquid, and appropriate fire safety measures should be in place in storage and handling areas. Containers should be kept tightly sealed when not in use to prevent contamination and moisture ingress. Personnel handling DBA should follow standard industrial safety practices, including the use of protective gloves, eye protection, and adequate ventilation.
The CAS number of Diethylene Glycol Monobutyl Ether Acetate (DBA) is 124-17-4. It is also known by the EINECS number 204-685-9 and the common name Butyl Carbitol Acetate.
In waterborne coatings and latex paints, DBA is used as a coalescing solvent. It supports film formation by softening latex polymer particles and contributes to formulation stability, color development, and touch-up properties in architectural coatings.
DBA has a water solubility of 65 g/L at 25°C. This partial water solubility allows it to distribute between the aqueous and polymer phases in waterborne coating systems, which supports both coalescence and formulation stability.
The boiling point of DBA is 245.3°C (473.5°F) at 760 mmHg (1.01 bar). Its high boiling point and evaporation rate of less than 0.01 (relative to n-butyl acetate = 1.0) make it a slow-evaporating solvent suitable for applications requiring extended open time.
DBA is available in iron drums, intermediate bulk containers (IBC), and ISO tank containers. The minimum order quantity for commercial procurement is typically one metric ton.
