pH Adjuster

MAGNESIUM NITRATE

CAS 10377-60-3
78

Safety score · 0–100

Fine

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

A mineral salt used at trace levels to stabilize MIT/MCI preservative blends. Salt itself is benign, but its presence usually signals isothiazolinones — that's the real concern to check.

Skin benefits

  • Stabilizes isothiazolinone preservative systems
  • Adjusts pH in some formulas
  • Used at very low concentrations

Known concerns

  • Almost exclusively paired with MIT/MCI sensitizers
  • Oxidizer in raw form — manufacturing handling concern
  • No standalone skin benefit
