Is palmitoyl dipeptide-5 diaminobutyroyl hydroxythreonine safe during pregnancy?
No harmonised CLP classification or SCCS/CIR reproductive safety restriction was found for this ingredient. No peer‑reviewed reproductive or developmental toxicity data were identified. As a large palmitoyl‑peptide used topically, dermal absorption is expected to be negligible, and there is no structural or mechanistic evidence of reproductive toxicity. Sources consulted include PubChem, CosIng, PubMed (no reproductive studies), ECHA (no Annex VI harmonised classification), and EWG.

Frequently asked questions
- Is palmitoyl dipeptide-5 diaminobutyroyl hydroxythreonine safe during pregnancy?
- No harmonised CLP classification or SCCS/CIR reproductive safety restriction was found for this ingredient. No peer‑reviewed reproductive or developmental toxicity data were identified.

- Is palmitoyl dipeptide-5 diaminobutyroyl hydroxythreonine safe while breastfeeding?
- No data indicating transfer into breast milk or lactation-related toxicity. Given the peptide's size/polarity and expected negligible systemic absorption after topical use, risk of exposure to breastfed infants is unlikely. No regulatory flags (ECHA Annex VI, SCCS, CIR) or peer‑reviewed evidence were found.
- Is palmitoyl dipeptide-5 diaminobutyroyl hydroxythreonine safe for baby skin?
- No infant‑specific reproductive or toxicology data located. Adult dermal absorption is expected negligible; however, infant skin has a higher surface‑area‑to‑weight ratio and immature barrier, so exposure score is increased by +1 for 0–3 yr. There is still no mechanistic or hazard evidence suggesting reproductive or developmental toxicity for infants.
