Additional information

Conclusion on classification

Methyl methacrylate is rapidly biodegradable and has low potential for bioaccumulation. Acute and chronic aquatic toxicity data are available for all three trophic levels.

According to the criteria of the CLP (EU-GHS) Directive 1272/2008 classification regarding hazards for the aquatic environment is not required.

According to the criteria of the GHS classification (GHS UN rev.3, 2009) MMA has to be classified for acute aquatic toxicity, category 3.
