The substance is inherently biodegradable, has a log Kow of 3.3 and all acute aquatic endpoints are greater than the threshold of 0.01 mg/L and the long-term ErC10 for algae, the most sensitive species, is 0.052 mg/L. the substance should therefore not be classified as vP/vB or PBT. The substance is not classified as CMR or STOT RE.
