VeriMomIs zinc oxide safe during pregnancy?
Zinc oxide (CAS 1314-13-2) has no harmonised reproductive classification and is not identified as a reproductive toxicant in primary safety assessments. Regulatory safety reviews (CIR; SCCS opinions on ZnO in sunscreens) conclude topical use is safe as used with negligible systemic absorption from skin, so reproductive hazard and mechanism are not supported and exposure from normal cosmetic topical use in pregnancy is negligible.

Frequently asked questions
- Is zinc oxide safe during pregnancy?
- Zinc oxide (CAS 1314-13-2) has no harmonised reproductive classification and is not identified as a reproductive toxicant in primary safety assessments. Regulatory safety reviews (CIR; SCCS opinions on ZnO in sunscreens) conclude topical use is safe as used with negligible systemic absorption from skin, so reproductive hazard and mechanism are not supported and exposure from normal cosmetic topical use in pregnancy is negligible.
- Is zinc oxide safe while breastfeeding?
- Same rationale as for pregnancy: no evidence of reproductive or lactation hazards, no known mechanism for breastmilk transfer following topical application, and dermal absorption is negligible for conventional zinc oxide formulations (CIR; SCCS).
- Is zinc oxide safe for baby skin?
- Hazard and mechanism remain unsupported. Exposure score increased by +1 versus adult because infant skin has a thinner barrier and higher surface-area-to-weight ratio; although adult dermal absorption is negligible, infant exposure from topical application is plausibly low but measurable (SCCS/CIR conclusions on minimal absorption; nano-form assessments note low potential for increased absorption but no reproductive signal).
- How does VeriMom score zinc oxide?
- VeriMom scores zinc oxide at 100/100 (no known risks) based on EU CosIng status, ECHA hazard classifications, and peer-reviewed PubMed studies. Our scoring pipeline is fully transparent.
