Packaging and shipping
Butyl Glycol (Ethylene Glycol Monobutyl Ether, EGBE) is a versatile glycol ether solvent widely used across industries such as coatings, inks, cleaning agents, agrochemicals, and specialty chemicals. From a procurement perspective, it is valued for its excellent solvency, strong coupling capability between water and oil phases, and stable chemical properties.
It features a balanced molecular structure with both hydrophilic and hydrophobic components, enabling effective dissolution of resins, oils, greases, and organic compounds. With a moderate evaporation rate and good compatibility in both aqueous and solvent-based systems, Butyl Glycol is particularly suitable for applications requiring controlled drying, improved flow, and consistent formulation performance.
Product Description
Anhui Eapearl Chemical Co., Ltd., as a leading professional manufacturer and solution provider of alcohol ether solvents in China, leverages advanced production technology, stringent quality control systems, and a fully integrated supply chain to supply the global market with high-performance Butyl Glycol (Ethylene Glycol Monobutyl Ether, EGBE). We are committed to positioning this versatile and highly efficient solvent as a key enabling material for customers across coatings, inks, cleaning, agrochemicals, and specialty chemicals industries, supporting continuous product innovation and process optimization.
Product Core Positioning
Butyl Glycol (Ethylene Glycol Monobutyl Ether) is one of the most widely used members of the glycol ether family. It is a medium-boiling, low-volatility solvent with excellent balance between hydrophilic and lipophilic properties. Its molecular structure, combining a hydrophilic ethylene oxide chain and a hydrophobic butyl group, enables it to function as an efficient “bridging solvent,” facilitating compatibility between water-based and oil-based systems.
With a boiling point of approximately 171°C, moderate evaporation rate, and strong solvency, Butyl Glycol demonstrates excellent performance in dissolving resins, oils, greases, dyes, and various organic compounds. It is particularly suitable for applications requiring controlled evaporation, good flow, and enhanced surface interaction.
Core application value and solutions
Butyl Glycol is widely used in water-based and solvent-based coatings as a coalescing agent and flow improver. It effectively enhances film formation by extending the open time, improving leveling, and reducing surface defects such as pinholes and brush marks. In architectural coatings, industrial paints, and printing inks, it contributes to improved gloss, uniformity, and overall finish quality. Its balanced evaporation rate ensures optimal drying performance without compromising film integrity.
Industrial and household cleaning (efficient degreasing solution):
With strong solvency for oils, greases, and organic contaminants, Butyl Glycol is a key component in industrial cleaners, degreasers, and household cleaning formulations. It effectively removes heavy dirt, carbon residues, and processing oils while maintaining compatibility with water-based systems. Its moderate evaporation rate allows sufficient contact time for enhanced cleaning efficiency, making it suitable for hard surface cleaning, metal treatment, and maintenance applications.
Agrochemical formulations (enhanced delivery performance):
As a solvent and penetration enhancer, Butyl Glycol improves the solubility of active ingredients in pesticide formulations. It enhances spreading, adhesion, and absorption on plant surfaces, thereby increasing bioavailability and overall effectiveness. Its compatibility with various formulation systems supports stable and efficient agrochemical products.
Specialty chemicals and industrial processing:
Butyl Glycol is extensively used as a solvent and intermediate in the production of resins, plasticizers, and chemical formulations. It also serves as a component in brake fluids, textile auxiliaries, and metalworking fluids, where its solvency and stability contribute to improved processing performance and product consistency.
Consumer chemicals:
In household and personal care formulations, Butyl Glycol acts as a coupling agent to stabilize mixtures of water and hydrophobic ingredients such as fragrances and essential oils. It enhances formulation clarity, stability, and user experience in products such as cleaners, polishes, and surface care solutions.
Anhui Eapearl Chemical Co., Ltd., with a series of high-performance alcohol ether solvents represented by diethylene glycol monobutyl ether (butyl carbitol), has always been committed to providing outstanding products, professional services, and reliable supply to become the most trustworthy partner for customers on their pursuit of process excellence and product innovation. We look forward to working with you to create higher value.
