Description of key information

Additional information

As not data on aquatic toxicity are available for 3-methylpent-1-en-3-ol, CAS 918-85-4, data from the analogous substance 2 -methylbut-2-en-2 -ol, CAS 115 -18 -4 were used to derive classification and labelling. 2-methyl-3-buten-2-ol was tested to be acutely not harmful to aquatic organisms indicated by effect values >500 mg/L. Hence, it can be assumed that 2 -methyl-3 -buten-2 -ol is, with high probability, acutely not harmful for aquatic organisms.
