Measured properties

Appearance: Silvery, whitish-gray, malleable, ductile metal. Mp: 1772 °C, bp: 2187 °C. Density: 21.45 g cm-3 at room conditions (very dense). Also shipped as a finely divided powder (platinum black), as a sponge, and as particles deposited on a supporting material such as alumina. Has strong catalytic activity in these forms, finely divided platinum can be dangerous to handle in the vicinity of other chemical · Appearance and odor vary depending upon the specific soluble platinum salt.

Irritation and sensitisation studies

3 skin studies and 2 eye studies are on record.

Classed as moderate1Classed as low1

The studies disagree (the most common conclusion covers 50%), 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.
