FAQ
- Is colloidal silver safe during pregnancy?
- Silver (CAS 7440-22-4) has a harmonised CLP classification in the EU as Repr. 2 (H361f), which by your rules maps to h=2; this is legally binding for the EU (22nd ATP / Delegated Regulation EU 2024/2564). Animal studies (silver nanoparticles and colloidal silver) demonstrate placental transfer and developmental effects in rodents, supporting a demonstrated mechanism (m=2). For topical cosmetic use absorption is generally low but measurable (ionic or nanoparticulate silver can be systemically absorbed under some conditions), so exposure from usual topical cosmetics is scored as low but measurable (e=1).
- Is colloidal silver safe while breastfeeding?
- Harmonised classification H361f applies irrespective of use context so h=2 applies to breastfeeding as well. Animal data show transfer of silver nanoparticles into breast milk and uptake by suckling offspring, demonstrating a route/mechanism of maternal-to-infant transfer (m=2). For typical topical cosmetic use maternal systemic levels are expected to be low but transfer into milk has been observed in animal studies and migration/leaching studies indicate low but measurable potential exposure, so e=1 (low but measurable).
- Is colloidal silver safe for baby skin?
- The harmonised H361f classification applies to the substance and therefore to concerns for infants (h=2). Mechanistic evidence from animal studies shows maternal–fetal and milk transfer and biological activity of silver nanoparticles (m=2); per your instructions infant-specific h/m should not be increased without infant-specific evidence, so they match the adult mechanistic score. Because infant skin has higher permeability/surface-area-to-weight, and silver (ions/NPs) has measurable absorption in some studies, exposure for baby skin is increased by +1 relative to adult (adult e=1 → baby e=2).
