Additional information
Conclusion on classification
Alpha-methylcinnamaldehyde is readily biodegradable, has a log Kow of <4 and its lowest reported acute effect concentration is an EC50 (growth rate) of 0.39 mg/l for algae.
The lowest chronic effect concentration for Cyprinal is an EC10 (reproduction) of 0.069 mg/l reported forDaphniafor the read-across substance HCA.
According to CLP the substance is classified as Aquatic Acute 1. and Aquatic Chronic 2.
