Frequently asked questions
- Is polybutylene terephthalate safe during pregnancy?
- Polybutylene terephthalate (PBT, CAS 26062-94-2) is a high‑molecular‑weight engineering polymer used as a solid plastic/resin. There is no harmonised CLP reproductive classification (ECHA Annex VI), no SCCS or CIR safety finding that flags reproductive hazard, and no peer‑reviewed evidence of developmental or reproductive toxicity for the polymer itself; polymers of this type are generally biologically inert with negligible dermal absorption (sources: ECHA registration summaries / Annex VI absence, PubChem, lack of CIR/SCCS assessments).
- Is polybutylene terephthalate safe while breastfeeding?
- No data indicating transfer into breastmilk or reproductive system effects for PBT; as a high‑MW polymer it is not expected to be systemically available after topical cosmetic use and therefore unlikely to reach breastmilk (sources: PubChem, ECHA registration data; no CIR/SCCS warnings).
- Is polybutylene terephthalate safe for baby skin?
- Hazard and mechanism: no evidence of reproductive or developmental hazard specific to infants. Exposure: although adult dermal absorption is expected to be negligible for a high‑MW insoluble polymer, infant skin has higher permeability/surface‑area‑to‑weight; therefore exposure score is increased by +1 to reflect potentially higher but still low measurable exposure from topical contact (sources: general polymer properties from PubChem/ECHA; no infant‑specific toxicity data).
- How does VeriMom score polybutylene terephthalate?
- VeriMom scores polybutylene terephthalate at 100/100 (no known risks) based on EU CosIng status, ECHA hazard classifications, and peer-reviewed PubMed studies. Our scoring pipeline is fully transparent.
