Frequently asked questions
- Is magnesium phosphate safe during pregnancy?
- No harmonised CLP reproductive or developmental classification on ECHA Annex VI for magnesium phosphate (CAS 10043-83-1), and no CIR or SCCS safety concern identified. PubChem/ECHA registration entries do not report reproductive toxicity or endocrine-mediated effects in available summaries; no peer‑reviewed reproductive teratology data were found. Therefore default no-evidence score is used (h=0, m=0) and topical exposure is expected to be negligible (e=0).
- Is magnesium phosphate safe while breastfeeding?
- No data indicating reproductive/developmental toxicity or lactation transfer for magnesium phosphate; absent harmonised classifications and no CIR/SCCS concerns. As an inorganic, low‑solubility magnesium salt used in cosmetics, systemic absorption from topical use is expected to be negligible, so exposure to nursing infants via maternal topical use is unlikely.
- Is magnesium phosphate safe for baby skin?
- No infant‑specific hazard data found. Magnesium phosphate is an inorganic, low‑solubility salt with no evidence of developmental toxicity; dermal absorption is expected to be negligible even on infant skin. Per instructions, exposure was not increased because the ingredient is not known to be appreciably absorbable.
