FAQ
- Is ci 77820 safe during pregnancy?
- Harmonised CLP in the Official Journal classifies silver nano (CAS 7440-22-4; particle diameter >1 nm ≤100 nm) as Repr. 2 H361f (and STOT RE2 H373) — a suspected reproductive toxicant; SCCS has also issued a safety opinion raising reproductive/developmental concerns for silver in cosmetics. Animal and mechanistic studies show that silver nanoparticles can translocate to placenta/fetus and cause developmental effects, supporting a demonstrated mechanism. (ECHA Official Journal; SCCS opinion; multiple rodent AgNP studies).
- Is ci 77820 safe while breastfeeding?
- Because the harmonised classification and animal data apply to silver nanoforms (H361f) and nanoparticles have been shown to translocate across biological barriers (including placenta) and distribute systemically in animal models, breastfeeding exposure cannot be excluded for nano/ionic silver — mechanism demonstrated in animal models though human milk data are limited. Topical cosmetic use of non-nano metallic silver is expected to give low but measurable systemic exposure only in special formulations or if nanoparticles/ions are present.
- Is ci 77820 safe for baby skin?
- For infants (0–3 yr) increase in exposure score is applied because immature skin barrier and higher surface-area-to-weight make absorption of nano/ionic silver more likely; harmonised H361f applies to silver nano specifically and animal/developmental studies show adverse effects after maternal exposure to AgNPs. For non-nano metallic silver pigment (micron-sized) dermal absorption is much lower, but nano/ionic forms pose the principal concern.
