Measured properties
- Appearance
- Acrylic acid is a colorless liquid with a distinctive acrid odor. Flash point 130 °F. Boiling point 286 °F. Freezing point 53 °F. Corrosive to metals and tissue. Prolonged exposure to fire or heat can cause polymerization. If polymerization takes place in a closed container, violent rupture may occur. The inhibitor (usually hydroquinone) greatly reduces the tendency to polymerize. · CBI, Dry Powder, Liquid

Irritation and sensitisation studies
8 skin studies and 3 eye studies are on record.
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.
