Frequently asked questions
- Is stearoxymethicone/dimethicone copolymer safe during pregnancy?
- No harmonised CLP classification for reproductive toxicity (ECHA Annex VI), no CIR or SCCS safety finding identifying reproductive hazard, and no peer‑reviewed studies reporting developmental or reproductive toxicity for this specific copolymer were identified in standard cosmetic safety sources. Silicone copolymers (including dimethicone derivatives) are generally regarded as inert film‑forming agents in topical cosmetics with low systemic availability under normal use (CIR, CosIng).
- Is stearoxymethicone/dimethicone copolymer safe while breastfeeding?
- No evidence of lactation/transfer or breastmilk exposure in regulatory reviews or peer‑reviewed literature for this ingredient; absence of harmonised reproductive classifications and no CIR/SCCS warnings indicate no known breastfeeding-specific hazard. Topical silicones are generally considered to have negligible systemic absorption, so transfer into breastmilk is unlikely under normal cosmetic use (CIR, PubChem).
- Is stearoxymethicone/dimethicone copolymer safe for baby skin?
- No infant-specific reproductive or developmental toxicity evidence was identified. However, infant skin has higher permeability and surface‑area‑to‑weight ratio, so exposure potential is higher than for adults; given typical low systemic absorption of silicone copolymers in adults, increase exposure score by one for 0–3 yr use (CosIng, CIR).
