FAQ

Is aziridine safe during pregnancy?
Aziridine (ethyleneimine, CAS 151-56-4) has harmonised/regulatory classifications and authoritative toxicology indicating mutagenic and carcinogenic properties (ECHA registration/C&L info, EPA/IRIS, IARC). Harmonised flags for reproductive hazard (suspected; H361 reported in regulatory sources) support 'suspected' reproductive hazard (h=2). The mechanism is well-supported as an alkylating/genotoxic agent (demonstrated genotoxicity/mutagenicity) so m=2. For topical exposure, aziridine is a small, reactive molecule with reported dermal absorption and clear systemic toxicity in occupational/animal data, so exposure from topical use would be at least measurable/moderate (e=2). Sources: ECHA dossier/C&L summaries, EPA IRIS/FACT sheet, NIOSH/NIH toxicology summaries, IARC summary.
Is aziridine safe while breastfeeding?
Same hazard and mechanism rationale as pregnancy (suspected reproductive/teratogenic risk via genotoxic/alkylating activity). No specific human lactation transfer data located, but systemic toxicity and dermal absorption reported in authoritative sources imply measurable maternal exposure and potential for transfer into breastmilk (therefore e=2).
Is aziridine safe for baby skin?
Hazard and mechanism as above (h=2, m=2). Because infant skin (0–3 yr) has higher surface-area-to-weight and an immature barrier, exposure score increases by +1 relative to adult topical exposure (adult e=2 → baby e=3). There is no infant-specific toxicokinetic evidence to change hazard or mechanism scores, only exposure.
How does VeriMom score aziridine?
VeriMom scores aziridine at 13/100 (high risk) based on EU CosIng status, ECHA hazard classifications, and peer-reviewed PubMed studies. Our scoring pipeline is fully transparent.
