Frequently asked questions
- Is polyphenylsilsesquioxane safe during pregnancy?
- No harmonised CLP reproductive classifications (H360/H361) or CIR/SCCS safety assessments located for poly(phenylsilsesquioxane) (CAS 70131-69-0). Available substance pages and supplier safety data sheets list general acute/inhalation hazards but provide no reproductive or developmental data; therefore default scoring is used. (ECHA substance page; supplier SDS).
- Is polyphenylsilsesquioxane safe while breastfeeding?
- No data indicating reproductive or lactation-specific hazards or milk transfer; no SCCS/CIR opinions or peer‑reviewed studies showing effects relevant to breastfeeding were found. Exposure from topical cosmetic use is expected to be negligible. (ECHA; supplier SDS; PubMed search returned no reproductive/lactation studies).
- Is polyphenylsilsesquioxane safe for baby skin?
- No infant-specific hazard or mechanistic data were found. As a high–molecular-weight film‑forming/occlusive silsesquioxane polymer with no demonstrated reproductive toxicity, hazard and mechanism scores remain 0; exposure is increased by +1 for infant skin because baby skin has an immature barrier and the ingredient is not demonstrated to be completely non‑absorbable. (Supplier/product descriptions; general ingredient properties).
