Measured properties

Appearance: Ammonium chloride is a white crystalline solid. It is soluble in water(37%). The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. It is used to make other ammonium compounds, as a soldering flux, as a fertilizer, and for many other uses. · Dry Powder, Liquid, Other Solid, CBI, Large Crystals

Irritation and sensitisation studies

6 skin studies and 6 eye studies are on record.

Classed as moderate1Classed as low4

The studies disagree (the most common conclusion covers 20%), 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.
