Where It Comes From
Present in some paint/adhesive removers, coatings, cleaners, and in electronics, battery, and petrochemical manufacturing [1].
How You Are Exposed
Breathing vapors during use, skin contact from splashes or soaked gloves, and working with NMP in poorly ventilated areas [1][3].
Why It Matters
Causes eye/skin irritation; higher or repeated exposure can harm the developing fetus; EPA found unreasonable risk for workers and consumers [1][2].
Who Is at Risk
Workers handling paint strippers, coatings, cleaners, or electronics/battery manufacturing; DIY users using paint removers; people who are pregnant or planning pregnancy [1][2].
How to Lower Your Exposure
Choose NMP‑free products; check labels/SDS; use outdoors or increase ventilation; avoid skin contact and wear chemical‑resistant gloves and eye protection; follow workplace controls and keep products away from children [1][3].
