Frequently asked questions
- Is tryptophan safe during pregnancy?
- Tryptophan (54-12-6) is an essential amino acid with no harmonised reproductive classification (ECHA Annex VI) and no SCCS/CIR safety finding indicating reproductive hazard; peer-reviewed data do not indicate teratogenicity from topical exposure. Dermal exposure from cosmetic use would be low but measurable due to small molecular weight and hydrophilicity (PubChem, CosIng).
- Is tryptophan safe while breastfeeding?
- No evidence of reproductive or lactation-specific toxicity or harmonised classification (ECHA Annex VI). Tryptophan is a normal dietary amino acid and not identified as a breastfeeding hazard in available sources; systemic exposure from topical use is expected to be low (PubChem, ECHA dossiers).
- Is tryptophan safe for baby skin?
- No infant-specific reproductive or developmental toxicity reported; no harmonised classification. Given measurable dermal absorption in adults (low), infant exposure is increased due to immature barrier and higher surface-area-to-weight, so exposure score is raised by one level (CosIng, PubChem).
- How does VeriMom score tryptophan?
