Frequently asked questions
- Is arginine/lysine polypeptide safe during pregnancy?
- No harmonised CLP reproductive classifications or SCCS/CIR safety concerns were identified for arginine/lysine polypeptide (CAS 31014-78-5) (ECHA Annex VI, CIR). No peer‑reviewed reproductive or developmental toxicology data were found in available literature sources (PubMed) and the ingredient is a short polypeptide expected to have low dermal/systemic availability (PubChem, CosIng).
- Is arginine/lysine polypeptide safe while breastfeeding?
- No evidence of reproductive or lactation hazards, no harmonised classification, and no mechanistic data indicating transfer into breast milk. Large/charged peptides such as arginine/lysine polypeptides generally have low dermal absorption and no specific human data indicate risk (ECHA, PubChem, CosIng).
- Is arginine/lysine polypeptide safe for baby skin?
- No infant‑specific toxicology or developmental effects reported. Given the peptide nature (water‑soluble, likely high molecular weight/charged), dermal absorption is expected to be negligible; therefore exposure for 0–3 yr skin is scored as negligible (CosIng, PubChem). Per instructions, exposure was not increased because absorption appears minimal and no data indicate measurable systemic uptake in adults.
