Frequently asked questions

Is hydrogenated butylene/ethylene/styrene copolymer safe during pregnancy?
No harmonised CLP reproductive classifications (ECHA Annex VI) nor CIR or SCCS safety findings indicating reproductive hazard for this polymer. Available databases (PubChem/CosIng) list it as a high‑molecular‑weight polymeric emollient/film former with no published reproductive toxicity or endocrine activity; therefore default hazard/mechanism = 0 and exposure from topical cosmetic use is expected negligible.
Is hydrogenated butylene/ethylene/styrene copolymer safe while breastfeeding?
Same rationale as for pregnancy: no evidence of reproductive or endocrine effects, no harmonised classification, and the polymer is expected to have negligible systemic absorption after topical use, so risk during lactation is not indicated.
Is hydrogenated butylene/ethylene/styrene copolymer safe for baby skin?
No infant‑specific reproductive or mechanistic hazards identified. As a high molecular weight polymer the ingredient is generally not systemically bioavailable, so hazard/mechanism remain 0. However, because infant skin barrier immaturity can increase percutaneous uptake compared with adults, a conservative exposure score of 1 is assigned for 0–3 yr skin even though direct measurements of infant absorption are lacking.
