FAQ
- Is methyl pyrrolidone safe during pregnancy?
- ECHA has a harmonised CLP classification H360D (May damage the unborn child) for N‑methyl‑2‑pyrrolidone (CAS 872‑50‑4), which is legally binding in the EU; multiple animal studies report reproductive/developmental toxicity (reduced fetal viability, malformations, developmental delays). These regulatory and animal data drive a confirmed reproductive hazard. ([echa.europa.eu](https://echa.europa.eu/documents/10162/355b86c1-5a0f-f104-0931-8ffdce4e1cbd?utm_source=openai))
- Is methyl pyrrolidone safe while breastfeeding?
- Because NMP is harmonised as H360D (may damage the unborn child) and animal data show reproductive/developmental effects, the conservative interpretation for lactation is high hazard (h=3); studies and registrations indicate systemic absorption and metabolites detected in biological matrices, supporting demonstrated systemic exposure and plausible transfer into milk. Regulatory classification and animal reproductive data are the principal bases. ([echa.europa.eu](https://echa.europa.eu/documents/10162/355b86c1-5a0f-f104-0931-8ffdce4e1cbd?utm_source=openai))
- Is methyl pyrrolidone safe for baby skin?
- Harmonised H360D and animal developmental toxicity justify h=3 for infant risk characterization. NMP is a small, water‑miscible solvent with measurable dermal absorption in occupational/SDS data and is systemically bioavailable, so infant exposure via topical application is increased (exposure score +1 for baby skin). Animal developmental studies and biomonitoring papers support systemic distribution. ([echa.europa.eu](https://echa.europa.eu/documents/10162/355b86c1-5a0f-f104-0931-8ffdce4e1cbd?utm_source=openai))
