Frequently asked questions
- Is magnesium hydroxide safe during pregnancy?
- No harmonised CLP reproductive classification (ECHA Annex VI) and no CIR or SCCS safety opinion indicating reproductive hazard. PubChem and peer-reviewed literature do not report developmental or reproductive toxicity for topical exposure to magnesium hydroxide; systemic exposure from cosmetic topical use is negligible.
- Is magnesium hydroxide safe while breastfeeding?
- No evidence of reproductive or lactation-specific toxicity and no harmonised classification. Given negligible dermal absorption from cosmetic use, transfer into breastmilk is not expected (supported by general toxicokinetic profiles in PubChem and absence of hazard statements in ECHA/CIR).
- Is magnesium hydroxide safe for baby skin?
- No evidence of infant-specific reproductive or developmental hazard. Dermal absorption of magnesium hydroxide from cosmetic formulations is considered negligible for adults; however, because infant skin can be more permeable, a small increase in exposure rating is applied (e=1) despite no indication of systemic toxicity in the literature or regulatory databases.
