Additional information

Conclusion on classification

According to Annex VI of Directive (EC) No  1272/2008, there is no environmental classification for hydroxypropyl methacrylate. The acute toxicity to daphnids, fish, and algae are > 97.2 mg/L. In addition,2-hydroxypropyl methacrylate has a low Kow (0.97) and is not expected to bioaccumulate. The substance also met the criteria of readily biodegradable based on the results from an OECD 301 C (Ready Biodegradability: Modified MITI Test (I)) test. Thus, environmental classification of hydroxypropyl methacrylate for acute or chronic aquatic hazards is not indicated.
