Frequently asked questions
- Is polylactic acid safe for baby skin?
- Hazard and mechanism remain unsupported for infants. Exposure score raised by +1 relative to adults because infant skin has higher permeability and surface‑area‑to‑weight ratio; PLA itself is a large polymer with low expected absorption but infant barrier immaturity makes low but measurable exposure plausible. No infant‑specific adverse data were identified (sources: general polymer behavior from PubChem/PubMed, CosIng; regulatory absence of reproductive classification in ECHA Annex VI).
