Frequently asked questions

Is bis-hea poly(1,4-butanediol)-9/ipdi copolymer safe during pregnancy?

No harmonised reproductive classification (ECHA Annex VI) or SCCS/CIR safety opinion specifically identifying reproductive hazards for this polymer were found in authoritative sources. As a high‑molecular‑weight polyurethane copolymer, systemic absorption from topical use is expected to be negligible; therefore no pregnancy reproductive hazard is indicated (CIR/SCCS absence of concerns; polymer behaviour per CosIng/PubChem-type listings).

Is bis-hea poly(1,4-butanediol)-9/ipdi copolymer safe while breastfeeding?

Same rationale as pregnancy: no authoritative sources (SCCS/CIR/ECHA harmonised CLP) identify reproductive or lactation transfer concerns for this polymer. Large polymeric materials are poorly absorbed topically, so transfer via milk is not expected.

Is bis-hea poly(1,4-butanediol)-9/ipdi copolymer safe for baby skin?

No data indicating specific developmental or infant skin hazards for the polymer in authoritative sources. Polymers of this class are generally not appreciably absorbed; infant exposure from topical cosmetic use is therefore expected to be negligible. If residual low‑MW monomers/oligomers are present, infant exposure profile could differ but no data were found to indicate such risk.
