Is silk extract safe during pregnancy?
No harmonised CLP reproductive classification found and no SCCS/CIR safety assessment identifying reproductive hazard. Peer‑reviewed literature on silk proteins reports biocompatibility and low toxicity; no animal or human reproductive/developmental toxicity signals located. Dermal absorption is expected to be negligible due to high molecular weight of silk proteins, so systemic exposure in pregnancy is unlikely (sources: ECHA Annex VI — no harmonised classification; PubMed; PubChem/CosIng entries list as cosmetic protein extract; EWG lists low concern).

Frequently asked questions
- Is silk extract safe during pregnancy?
- No harmonised CLP reproductive classification found and no SCCS/CIR safety assessment identifying reproductive hazard. Peer‑reviewed literature on silk proteins reports biocompatibility and low toxicity; no animal or human reproductive/developmental toxicity signals located. Dermal absorption is expected to be negligible due to high molecular weight of silk proteins, so systemic exposure in pregnancy is unlikely (sources: ECHA Annex VI — no harmonised classification; PubMed; PubChem/CosIng entries list as cosmetic protein extract; EWG lists low concern).
- Is silk extract safe while breastfeeding?
- No evidence of lactation/transfer or reproductive endocrine activity in available literature and no regulatory flags. High molecular weight proteins applied topically are unlikely to reach systemic circulation in amounts sufficient to appear in breast milk; therefore exposure to breastfed infants is expected to be negligible.
- Is silk extract safe for baby skin?
- No reproductive or developmental hazard identified. Dermal exposure for infants should be considered higher than adults due to immature barrier and higher surface‑area‑to‑weight; although adult dermal absorption is negligible for silk proteins, infant skin may permit slight increase in exposure — assigned exposure score +1 relative to adult. No infant‑specific toxicity data found.
- How does VeriMom score silk extract?
