Additional information
According to data of structural analogues 2-decyltetradecanol does not produce toxicity in freshwater aquatic organisms on all three trophic levels (fish, daphnia, and alga) in acute toxicity studies up to the limit of the water solubility. In addition, due to low water solubility and high biodegradation, it is not technically feasible to conduct chronic ecotoxicity studies on 2-decyltetradecanol. Since 2-Decyltetradecanol does not cause acute toxicity and it is not possible to conduct chronic studies due to low solubility and rapid biodegradability, the alcohol is unlikely to pose a hazard to aquatic life. Similarly, technical difficulties would be incurred in sediment toxicity testing due to low solubility and rapid biodegradation, resulting in 2 -decyltetradecanol being unlikely to be hazardous to sediment organisms. Indirect exposure is not expected in the terrestrial environment as rapid biodegradability means 2-decyltetradecanol will be biodegraded within the STP process and as a consequence a transfer to the soil compartment via STP effluent is not expected. 2-decyltetradecanol will not be directly applied to soils and as such, direct exposure to soil organisms is not expected.
However, it is possible to qualitatively conclude based on low solubility and available effects test data for aquatic organisms that 2-decyltetradecanol does not pose a risk to the marine sediment compartment.
Conclusion on classification
According to data of structural analogues, 2-decyltetradecanol does not produce toxicity in aquatic organisms in acute toxicity studies up to the limit of the water solubility. Based on an absence of toxicity to aquatic, sediment and terrestrial organisms, unlikely potential for bioaccumulation and the rapid biodegradation of 2 -decyltetradecanol in the environment, it is concluded that the long chain alcohol does not pose hazard to the water, sediment or terrestrial compartment. 2 -Decyltetradecanol is not classified as a hazard to the environment.
