Frequently asked questions

Is hydrolyzed silk safe during pregnancy?
No harmonised CLP classification (ECHA Annex VI) or SCCS/CIR reproductive restrictions were identified for hydrolyzed silk; no peer-reviewed reproductive or teratogenic signals were found in the literature. As a large peptide/protein-derived cosmetic ingredient it is not expected to present reproductive hazard or significant dermal absorption in adults (sources searched: ECHA Annex VI, PubChem, CosIng, PubMed, EWG).
Is hydrolyzed silk safe while breastfeeding?
No data indicating reproductive or lactation-related hazard, no harmonised classification, and no mechanistic data suggesting transfer into breastmilk. Topical use of hydrolyzed silk is not expected to result in meaningful systemic exposure in adults (sources searched: ECHA Annex VI, PubChem, CosIng, PubMed, EWG).
Is hydrolyzed silk safe for baby skin?
No infant-specific toxicology or harmonised hazard was identified. Adult dermal absorption is expected to be negligible for peptide/protein-based hydrolysates, but because infant skin has a higher surface-area-to-weight ratio and an immature barrier, a conservative exposure score of 1 is applied for 0–3 yr skin (no evidence of infant-specific harm) (sources searched: PubMed, CosIng, EWG, PubChem).
How does VeriMom score hydrolyzed silk?
VeriMom scores hydrolyzed silk 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.
