Frequently asked questions
- Is tetrapeptide-26 safe during pregnancy?
- No harmonised CLP classification (ECHA Annex VI) or SCCS/CIR safety assessment listing reproductive or developmental hazard for tetrapeptide-26. No peer-reviewed evidence of reproductive toxicity or teratogenicity located in available regulatory/authoritative sources; peptides of this type are generally assessed case-by-case and, in the absence of specific signals, default to no evidence of reproductive hazard. Sources: ECHA Annex VI (no entry), SCCS/CIR (no assessment), PubMed (no reproductive toxicity studies identified), CosIng/EWG (ingredient listings without reproductive flags).
- Is tetrapeptide-26 safe while breastfeeding?
- No data indicating lactation or breast‑milk transfer or effects on nursing infants. No harmonised classification or authoritative safety assessment raising concerns. Given peptide chemical nature and topical cosmetic use, there is no evidence for breastfeeding-specific hazard in the consulted regulatory sources.
- Is tetrapeptide-26 safe for baby skin?
- No hazard or mechanistic reproductive/endocrine concerns identified. Exposure score increased to 1 for baby skin (vs adult 0) because baby/infant skin has an immature barrier and higher surface-area-to-weight ratio; while tetrapeptides are generally of low permeability, measurable percutaneous absorption cannot be excluded for infants, so exposure is considered low but non‑negligible. No infant‑specific toxicity data were identified.
