Measured properties

Appearance: Magnesium appears as a light silvery metal. The more finely divided material reacts with water to liberate hydrogen, a flammable gas, though this reaction is not as vigorous as that of sodium or lithium with water. In finely divided forms is easily ignited. Burns with an intense white flame. Can be wax coated to render magnesium as nonreactive. · Magnesium powder appears as a light silvery colored powder.

Irritation and sensitisation studies

3 skin studies and 1 eye studies are on record.

Classed as moderate1Classed as low2

The studies disagree (the most common conclusion covers 33%), so they do not establish that this ingredient is irritating. These tests are on the raw material itself; irritation at the amount in a finished product is a different question.
