Key physicochemical properties

Solubility: Tetraethylene glycol butyl ether is soluble in water and various organic solvents (such as ethanol); possesses both polar and non-polar groups, offering excellent compatibility.
High boiling point: With a boiling point as high as 318–320°C, it is a typical high-boiling-point solvent that remains present for an extended period during the film-forming process.
Density and vapor pressure: Density is approximately 1.003 g/cm³; vapor pressure is extremely low (0.015 Pa) at 25°C, resulting in a very slow evaporation rate.

Key Application Areas

With its excellent solvency and very slow evaporation rate, tetraethylene glycol butyl ether plays a key role in various industrial sectors:
Coatings and Inks: Serving as a high-boiling solvent and leveling agent, it effectively reduces system viscosity, extends open time, and prevents defects such as orange peel and cracking in the paint film.
Electronics Cleaning: Used for degreasing and photoresist stripping on precision electronic components and semiconductor surfaces, it evaporates slowly and leaves minimal residue.
Personal Care: Acting as a humectant and mild solvent in cosmetics, it facilitates the penetration of active ingredients and helps maintain the product's moisturizing feel.
Other Industrial Applications: Widely used as an adjuvant for pesticide emulsifiable concentrates, an additive for oilfield drilling fluids, and a plasticizer in the processing of polymers such as polyurethane.

Safety and Storage

Hazard characteristics: Tetraethylene glycol butyl ether poses a risk of causing serious eye damage.(H318); safety goggles and solvent-resistant gloves must be worn during handling.
First aid measures: In case of contact with eyes or skin, immediately rinse with plenty of running water for at least 20 minutes and seek prompt medical attention.
Storage requirements: Store in a tightly sealed container in a cool, dry, and well-ventilated warehouse, away from open flames, heat sources, and strong oxidizing agents.
