Frequently asked questions

Is potassium carbonate safe for baby skin?

No infant-specific reproductive/toxicology data and no mechanistic concern; hazard and mechanism remain 0. Because potassium carbonate is a water‑soluble ionic compound (not completely non‑absorbable) and infant skin has higher permeability/surface‑area‑to‑weight, exposure is increased by one category for baby skin relative to adults (adult e=0 → baby e=1). Note: local irritation from alkaline pH is a separate concern but not scored here for systemic reproductive risk. (Sources: PubChem, CosIng, ECHA registration dossiers.)

Is potassium carbonate safe for newborns?

No infant-specific reproductive/toxicology data and no mechanistic concern; hazard and mechanism remain 0. Because potassium carbonate is a water‑soluble ionic compound (not completely non‑absorbable) and infant skin has higher permeability/surface‑area‑to‑weight, exposure is increased by one category for baby skin relative to adults (adult e=0 → baby e=1). Note: local irritation from alkaline pH is a separate concern but not scored here for systemic reproductive risk. (Sources: PubChem, CosIng, ECHA registration dossiers.)
