Frequently asked questions
- Is isoleucine safe during pregnancy?
- Isoleucine is an essential amino acid with no harmonised CLP reproductive classification (ECHA Annex VI) and no SCCS/CIR safety concerns identified. No peer-reviewed evidence of reproductive or teratogenic effects from topical use was found; systemic maternal exposure from cosmetic topical application is expected to be low but measurable (water‑soluble small molecule) so e=1 (low). Sources: ECHA Annex VI (no harmonised classification), PubChem, CosIng, PubMed literature search (no reproductive toxicity reports).
- Is isoleucine safe while breastfeeding?
- No evidence of reproductive or lactation-specific toxicity; topical cosmetic use is unlikely to produce significant systemic levels that would meaningfully expose breast milk. No harmonised flags or CIR/SCCS concerns identified. Sources: ECHA Annex VI, PubChem, CosIng, PubMed.
- Is isoleucine safe for baby skin?
- No infant-specific hazards reported. Isoleucine lacks reproductive or developmental toxicity signals and is used as a skin-conditioning amino acid (CosIng); however, infant skin has higher permeability and surface‑area‑to‑weight, so exposure is increased by one category relative to adults (adult e=1 → infant e=2). No harmonised classification or SCCS/CIR concerns. Sources: CosIng, PubChem, ECHA Annex VI, PubMed.
