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

A mineral complex of magnesium, aluminum, and zinc carbonates and hydroxides used as an oil-absorbing and skin-protective agent in cosmetic formulations.

Magnesium/Aluminum/Zinc/Hydroxide/Carbonate is a basic (alkaline) inorganic complex commonly referred to as a hydrotalcite-like compound. These layered double hydroxide structures have high oil-absorbing capacity and are used in cosmetic formulations for their mattifying, oil-control, and skin-protective properties. The combination of magnesium, aluminum, and zinc provides a balanced safety profile, as these metals are essential nutrients and have well-established toxicological profiles. The ingredient is not listed in EU Annex II or III restrictions.

Skin benefits

  • Oil absorption and mattifying effect
  • Skin protection barrier
