Triglycol Monobutyl Ether

Triglycol monobutyl ether (also called triethylene glycol monobutyl ether) is a glycol ether solvent used in cleaners, paints, inks, and some automotive and personal-care products. It belongs to EPA’s “glycol ethers” group of hazardous air pollutants; exposures can irritate eyes/skin and, at high levels, affect the nervous system, while some related glycol ethers have shown reproductive effects [1][2].

Where It Comes From

Made and used as a solvent in water‑based cleaners, coatings, inks, and brake fluids; can be released during manufacturing and product use, especially indoors [1].

How You Are Exposed

Breathing vapors or mists during cleaning/painting, skin contact with liquids, or workplace air in manufacturing and maintenance settings [1].

Why It Matters

Causes irritation to eyes, skin, and airways; high exposures may cause headache or dizziness. Some glycol ethers have affected blood and reproduction in studies; data for this specific chemical are more limited, so caution is advised [1].

Who Is at Risk

Workers using solvent-based cleaners/coatings, people using concentrated products in poorly ventilated spaces, and pregnant workers due to potential class effects [1].

How to Lower Your Exposure

Use in well-ventilated areas, keep containers closed, wear chemical-resistant gloves, follow label directions, and choose products labeled low in or free of glycol ethers when possible [1][2].
