Description of key information
48 hrs aquatic toxicity studies (SSS QSAR prediction model, 2016) were conducted to assess toxic effects of the 2-methyl-4-(2,2,3-trimethyl-3-cyclopenten-1-yl)-2-buten-1-ol (CAS no 28219-60-5) and the results were predicted. The study was based on the effects of the test compound on the Daphnia magna in a static fresh water system. The predicted data suggests the effective concentration (EC50) for the 2-methyl-4-(2,2,3-trimethyl-3-cyclopenten-1-yl)-2-buten-1-ol (CAS no 28219-60-5) was estimated to be 0.035537671 mg/L on the basis of intoxication.

48 hrs aquatic toxicity studies (EPI suite, ECOSAR version 1.1, 2016) were conducted to assess toxic effects of the 2-methyl-4-(2,2,3-trimethyl-3-cyclopenten-1-yl)-2-buten-1-ol (CAS no 28219-60-5) and the results were predicted. The study was based on the effects of the test compound on the Daphnia magna in a static fresh water system. The predicted data suggests the lethal concentration (LC50) for the 2-methyl-4-(2,2,3-trimethyl-3-cyclopenten-1-yl)-2-buten-1-ol was estimated to be 0.486 mg/L.
On the basis of results for toxicity to aquatic invertebrates, it can be considered that the substance is likely to be toxic to aquatic biota and can be classified in Acute category 1 as per the criteria of CLP regulation
