Frequently asked questions
- Is polymethylsilsesquioxane/silica crosspolymer safe during pregnancy?
- No harmonised CLP reproductive classifications (ECHA Annex VI) or SCCS/CIR safety findings indicating reproductive hazard for polymethylsilsesquioxane/silica crosspolymer. The ingredient is a silicone/silica crosspolymer used as a cosmetic texture/feel modifier and is considered essentially inert with negligible systemic absorption in topical use (CosIng, PubChem; no reproductive or teratogenic signals found in PubMed).
- Is polymethylsilsesquioxane/silica crosspolymer safe while breastfeeding?
- No evidence of lactation/breastfeeding-specific reproductive or developmental toxicity; no harmonised classification or CIR/SCCS restriction. Expected negligible systemic absorption from topical use, so transfer to breast milk is unlikely.
- Is polymethylsilsesquioxane/silica crosspolymer safe for baby skin?
- No infant-specific reproductive or developmental hazards identified. Polymethylsilsesquioxane/silica crosspolymer is a particulate/film-forming silicone-silica material with negligible dermal absorption in adults, but because infant skin has a less mature barrier the exposure score is conservatively increased by one level (per instruction) to reflect potentially higher, though still low, percutaneous exposure. No data indicate infant-specific toxicity.
