Is protease safe during pregnancy?
No harmonised CLP reproductive classification or SCCS/CIR reproductive safety finding was identified for protease (CAS 9001-92-7). Regulatory/ingredient databases list protease as a cosmetic enzyme (CosIng/INCI) and ECHA substance pages group it with proteases but do not show a harmonised H360/H361 or other reproductive hazard. Peer‑reviewed literature and regulatory dossiers instead raise occupational allergy/sensitisation concerns for proteolytic enzymes, not reproductive toxicity; therefore default scoring is 0/0/0. Sources: ECHA substance page, CosIng listing, PubMed sensitisation literature.

Frequently asked questions
- Is protease safe during pregnancy?
- No harmonised CLP reproductive classification or SCCS/CIR reproductive safety finding was identified for protease (CAS 9001-92-7). Regulatory/ingredient databases list protease as a cosmetic enzyme (CosIng/INCI) and ECHA substance pages group it with proteases but do not show a harmonised H360/H361 or other reproductive hazard. Peer‑reviewed literature and regulatory dossiers instead raise occupational allergy/sensitisation concerns for proteolytic enzymes, not reproductive toxicity; therefore default scoring is 0/0/0. Sources: ECHA substance page, CosIng listing, PubMed sensitisation literature.
- Is protease safe while breastfeeding?
- No data indicating protease causes reproductive or lactation/offspring effects or a mechanism for transfer into breastmilk; regulatory listings and literature do not report developmental or lactation toxicity for cosmetic proteases. Primary safety concerns reported are local irritation and allergic sensitisation (including inhalation exposure in occupational settings), not systemic reproductive/lactation effects.
- Is protease safe for baby skin?
- No infant‑specific reproductive/toxicity data were found. Protease is used as a topical enzyme (INCI Protease) and is primarily associated in the literature with skin irritation and sensitisation risk (including occupational inhalation) rather than systemic reproductive toxicity. Topical dermal absorption of intact protease enzymes is expected to be negligible in healthy adult skin (so adult exposure = 0), but because infant skin has an immature barrier and higher surface‑area‑to‑weight, exposure score is increased by +1 (e=1). No evidence was found that would increase hazard or mechanism scores for infants.
- How does VeriMom score protease?
- VeriMom scores protease 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.
