Frequently asked questions
- Is potassium isostearate safe during pregnancy?
- No harmonised CLP reproductive classifications (ECHA Annex VI) or SCCS/CIR reproductive safety flags were identified for potassium isostearate or closely related fatty‑acid salts; fatty‑acid soap/surfactant salts are generally regarded as non‑reproductive toxicants (see ECHA dossiers, PubChem, CosIng). No peer‑reviewed or regulatory evidence of developmental or teratogenic effects was found.
- Is potassium isostearate safe while breastfeeding?
- No evidence of reproductive or lactation‑related toxicity in regulatory sources; as a fatty acid salt/surfactant with low systemic toxicity and no harmonised classifications, breastfeeding risk is not indicated (ECHA dossiers, PubChem, CosIng).
- Is potassium isostearate safe for baby skin?
- Hazard and mechanism: no reproductive/teratogenic evidence for this ingredient or its parent fatty acid (h and m = 0). Exposure: topical absorption from fatty‑acid salts is generally low in adults but infant skin has higher permeability, so exposure is increased modestly for 0–3 yr (e = 1) — see general guidance in CosIng/ECHA on cosmetic surfactants and skin permeability.
