HUMAN HEALTH RISK ASSESSMENT FOR ALUMINIUM, …

However, it is clear that for many of the aluminium compounds, the degree of hydration can vary. Recently, the presence of a thin surface coating of ultrafine particles of sodium fluoride on aluminium oxide particulates has been demonstrated for aerosols collected in an aluminium refinery (Höflich et al., 2005; L’vov et al., 2005).

Sodium Bicarbonate vs. Aluminum Oxide | Skin Deep Solutions

Aluminum Oxide has been documented to irritate the skin and throat, cause scratchy eyes, allergic reactions, respiratory problems and in some instances produce low-grade fevers. In searching for safe alternatives, we experimented with various possible crystal mediums. After testing more than thirty compounds, results proved the safest and most effective was sodium bicarbonate, more commonly known as “baking soda.”

ACID-BASE BEHAVIOUR OF THE PERIOD 3 OXIDES

Aluminium oxide is amphoteric. It has reactions as both a base and an acid. Reaction with water. Aluminium oxide doesn't react in a simple way with water in the sense that sodium oxide and magnesium oxide do, and doesn't dissolve in it. Although it still contains oxide ions, they are held too strongly in the solid lattice to react with the water.
