Conclusion on classification

Short-term toxicity results for daphnia and algae are available for the substance. The EL50 and ErL50 are 9.01 and 65.4 mg/L, respectively. Based on the lowest available acute data, in this case daphnia, the substance does not need to be classified for acute aquatic toxicity according to Table 4.1.0 (a) of CLP.

As only one reliable long-term toxicity endpoint is available from the algae study, chronic classification needs to be derived on both acute and chronic data and the worst case should be taken.

Based on chronic data (ErL10 = 22.2 mg/L), Ginger hot flavor extract (non-volatile) does not have to be classified according to CLP Table 4.1.0 b(i). However, in view of the substance not being readily biodegradable, having a log Kow range of 2.72 - 5.31 (25.5% of the substance with a log Kow >= 4.0) and the lowest acute data point being 9.01 mg/L for daphnids, the substance needs to be classified for long term aquatic toxicity according to Figure 4.1.1 and Table 4.1.0, (b) iii of CLP, resulting in aquatic Category Chronic 2 (H411) classification.

As the worst case needs to be taken, Ginger hot flavor extract (non-volatile) needs to be classified Chronic Category 2 (H411) according to EU CLP (EC 1272/2008 and its updates). M factor for acute and chronic toxicity is not applicable
