Additional information

All aquatic tests were performed using the test substance diluted in an 8 : 17 mixture of 1-methoxy-2-propyl acetate (CAS: 108-65-6) and solvent naphtha 100 (CAS: 64742-95-6), respectively. The test solution consisted to 75 % of the test item and to 25 % of the 1-methoxy-2-propyl acetate/solvent naphtha mixture. As the test substance is only marketed in the above described composition, these tests can be used for the evaluation of the environmental risks of the substance. The results further display a worst case as the test substance is almost insoluble in water and will therefore not be available in large amounts (if at all) in aquatic test systems. This is also the reason for the high effect value determined in the acute toxicity test to fish (LC50(96 h)= 562 mg/L) although the water solubility of the test item is <0.1 mg/L. As a conclusion the aquatic toxicity studies with the test substance diluted in organic solvents can be used as a worst case describing the toxicological behaviour of the test substance against aquatic organisms.

Conclusion

Based on the available results, the registered substance does not exhibit acute toxicity effects at its solubility limit to the three trophic levels and the microorganisms.

Conclusion on classification

The registered substance is slightly soluble in water and does not exhibit acute toxicity effects to the three trophic levels at its solubility limit (<0.1 mg/L). Further the substance is not readily biodegradable but does not have a potential for bioaccumulation.

As a conclusion to the results listed above the substance does not have to be classified.
