Frequently asked questions

Is sulfur safe during pregnancy?
Elemental sulfur (CAS 7704-34-9) has a harmonised CLP classification for skin irritation (H315) but no harmonised reproductive classifications (no H360/H361). There is no authoritative evidence (SCCS/CIR/harmonised CLP) indicating reproductive or developmental toxicity from topical cosmetic use, and systemic absorption from topical sulfur is negligible in typical formulations, so pregnancy hazard and exposure scores are 0. Sources: ECHA Annex VI (H315); PubChem/ECHA registration data indicate low systemic uptake.
Is sulfur safe while breastfeeding?
No authoritative data or classifications indicate reproductive or lactation hazards for elemental sulfur. With negligible dermal absorption from cosmetic use, transfer into breast milk is not expected; therefore hazard, mechanism and exposure scores are 0. Sources: ECHA Annex VI; PubChem/ECHA registration information; CosIng entry for sulfur (no lactation warnings).
Is sulfur safe for baby skin?
No evidence of developmental or infant-specific toxicity; hazard and mechanism remain 0. Because infant skin has higher permeability/SA:body-weight, a conservative increase in exposure score to 1 is applied despite sulfur’s generally low dermal absorption. Main regulatory concern for sulfur remains topical irritation (H315). Sources: ECHA Annex VI (H315); general product safety data from PubChem/CosIng indicating topical use and low systemic absorption.
