Frequently asked questions
- 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.
