Measured properties

Appearance: 2-dimethylaminoethyl methacrylate appears as a clear colorless liquid. Less dense than water and insoluble in water. Vapors heavier than air and corrosive to eyes and mucous membranes. May polymerize exothermically if heated or contaminated. If polymerization takes place inside a closed container, the container may rupture violently. Produces toxic oxides of nitrogen during combustion. Toxic by sk · Liquid

Irritation and sensitisation studies

7 skin studies and 3 eye studies are on record.

Classed as moderate2

The study conclusions largely agree (100%). These tests are on the raw material itself; irritation at the amount in a finished product is a different question.
