Frequently asked questions
- Is magnesium silicate safe during pregnancy?
- No harmonised reproductive classification (ECHA Annex VI) and no CIR or SCCS safety opinion flagging reproductive toxicity for magnesium silicate. PubChem and CosIng list magnesium silicate as an inert inorganic mineral with no reported developmental/reproductive animal or human data indicating teratogenicity or fertility effects.
- Is magnesium silicate safe while breastfeeding?
- Topical use of magnesium silicate is expected to have negligible systemic absorption based on its inorganic particulate nature; no data indicate effects on lactation or transfer into breast milk (sources: PubChem, CosIng, PubMed searches found no reproductive/lactation studies).
- Is magnesium silicate safe for baby skin?
- Hazard and mechanism: no evidence of reproductive or developmental hazard specific to infants (ECHA Annex VI, PubChem). Exposure: adult dermal absorption for an inorganic particulate is negligible, but per guidance immature infant skin has higher absorption potential — therefore exposure score increased by +1 for babies (practical exposure from topical powders/creams remains low) (sources: CosIng, EWG, general toxicokinetic rationale).
