CAS 112-50-5

Ethoxytriglycol

Ethoxytriglycol (triethylene glycol monoethyl ether) is a glycol ether solvent used in paints, inks, cleaners, and other household and industrial products. It can irritate eyes and lungs; some related glycol ethers have also affected blood and reproduction at high exposures, so minimizing contact matters [1][3][4].

Where It Comes From

Made as a solvent/flow agent for coatings, inks, detergents, and brake fluids; it can be released to indoor air during product use and drying [1][2].

How You Are Exposed

Breathing vapors while using or heating products; skin contact during cleaning or painting; workplace air in printing, painting, or auto repair [1][2].

Why It Matters

Short-term exposure may cause eye, skin, and airway irritation, headaches, or dizziness; some glycol ethers damage blood and fertility in studies, though data for ethoxytriglycol are limited [1][3][4].

Who Is at Risk

Workers using solvent-based products, people in poorly ventilated spaces, and those who are pregnant or trying to conceive (based on related glycol ethers) [1][3][4].

How to Lower Your Exposure

Choose low‑VOC or glycol‑ether‑free products, ventilate well, wear chemical‑resistant gloves, close containers, and follow labels; at work, use local exhaust and PPE per your safety program [1][5].
