FAQ
- Is 4,4'-isopropylidenediphenol safe during pregnancy?
- Bisphenol A (4,4'-isopropylidenediphenol) has a harmonised CLP classification including Repr. 1B (H360F) under ECHA Annex VI, which by calibration requires h=3. BPA is a demonstrated endocrine disruptor with evidence of placental/fetal transfer and fetal effects in animal and human-focused reviews (mechanism score m=2). For topical cosmetic use, dermal absorption is measurable but generally lower than dietary routes, so exposure for pregnant adults is scored as low-measurable (e=1).
- Is 4,4'-isopropylidenediphenol safe while breastfeeding?
- Harmonised Repr.1B (H360F) applies to BPA so h=3. BPA demonstrates endocrine activity and is transferred into breast milk; human biomonitoring and review literature document detectable BPA in breast milk and infant exposure (m=2). Because breastfeeding transfers systemic BPA to the infant (measured in milk and infant urine), exposure is moderate (e=2).
- Is 4,4'-isopropylidenediphenol safe for baby skin?
- The parent compound BPA carries harmonised H360F → h=3. Mechanistic evidence of endocrine activity and developmental effects supports m=2. For topical exposure to infants (0–3 yr) the exposure score is increased by +1 relative to adults due to immature skin and higher surface-area-to-weight; given measurable dermal absorption in adults (used in cosmetics) adult e=1 → infant e=2.
