Frequently asked questions
- Is potassium persulfate safe for baby skin?
- No infant-specific developmental or reproductive toxicity data or classifications exist in harmonised CLP; thus hazard (h) and mechanism (m) are 0. Because infant skin has higher permeability and the adult exposure was judged low (e=1), exposure for 0–3 yr skin is increased by one to moderate (e=2). Note: the compound is a known skin and respiratory sensitiser and irritant, so contact may cause local harm in babies even without systemic reproductive effects (ECHA Annex VI).
