The aquatic toxicity information of Geranyl Isobutyrate MCS is
derived from read across from Citronellyl butyrate. The EC50 value of
algae and Daphnia magna is > 0.16 and 0.41 mg/L, respectively, and of
which the Daphnia has the lowest acute value. Since the EC50 value is ≤
1 mg/L, the substance needs to be classified as Acute Cat. 1 (H400)
according to EU CLP (EC No. 1272/2008 and its amendments: Table 4.1.0;
There is only one chronic algae value available which is the EC10
of 0.083 mg/l. According to EU CLP Figure 4.1.1, the chronic
classification has to be determined based on this chronic value
according to Table 4.1.0, (b) ii (as the substance is readily
biodegradable) and results in Chronic 2.
As only one chronic value is available the chronic classification
needs to be derived from both chronic information and acute information
from the other trophic level and the most stringent outcome should be
The EC50 value for Daphnia magna is ≤ 1 mg/L and in combination
with the log Kow >=4 (despite the substance is readily biodegradable)
the substance needs to be classified as Chronic 1. This is the most
Overall, it can be concluded that the
substance needs to be classified for environmental hazards as Acute Cat.
