Frequently asked questions
- Is hydrogenated styrene/isoprene copolymer safe for baby skin?
- Polymers of this type are high molecular weight, lipophilic film formers with negligible dermal penetration; therefore exposure from topical use is considered negligible even for infant skin and there are no infant‑specific toxicity reports or regulatory warnings. No increase in hazard or mechanism scores is warranted. (Sources: CosIng, PubChem, ECHA information indicating polymeric inert status.)
- Is hydrogenated styrene/isoprene copolymer safe for newborns?
- Polymers of this type are high molecular weight, lipophilic film formers with negligible dermal penetration; therefore exposure from topical use is considered negligible even for infant skin and there are no infant‑specific toxicity reports or regulatory warnings. No increase in hazard or mechanism scores is warranted. (Sources: CosIng, PubChem, ECHA information indicating polymeric inert status.)
