    Magnesium Aluminum Silicate

    What is it?

    Magnesium Aluminum Silicate is a naturally occurring mineral derived from refined and purified clay that is used primarily as a thickener in cosmetics and beauty products. It is naturally of a flaky, white consistency and is used most often as a filler in deodorants, shaving creams and thick lotions.

    Safety Measures/Side Effects of Magnesium Aluminum Silicate:

    According to the Cosmetic Database, Magnesium Aluminum Silicate is approved by the CIR Expert Panel, but only in limited concentrations. The CIR's concern stems from the known risk of any ingredient that contains aluminum compounds, which are known neurotoxins.

    A study published in the International Journal of Toxicology in 2003 found that Magnesium Aluminum Silicate was a weak irritant in testing on rabbits; it has otherwise been considered to be safe for use in cosmetics and beauty products.

    Key Information

    • Magnesium Aluminum Silicate has unusually large molecules; because of these large molecules, it is unable to be absorbed into the skin.

    More Information

    Magnesium Aluminum Silicate was a weak primary skin irritant in rabbits and had no cumulative skin irritation in guinea pigs. No gross effects were reported in any of these studies.

    Magnesium Aluminum Silicate and Sodium Magnesium Silicate caused minimal eye irritation in a Draize eye irritation test.

    Magnesium Aluminum Silicate had neither a teratogenic nor adverse effects on the mouse fetus.
