Conclusion on classification
Conclusion on Classification:
In the absence of adequate aquatic chronic toxicity information from all three trophic levels, the classification was based on the short-term aquatic toxicity values from laboratory experimental studies available from two trophic levels (72-h ErC50 = 67.8 mg/L in algae, 48-h LC50 > 100 mg/L in daphnids). In the absence of a laboratory study on acute toxicity in fish, the environmental classification was based upon the lower of the two L(E)C50 values for algae and aquatic invertebrates (i.e., the 72-h ErC50 of 67.8 mg/L in algae). The substance has been shown to be readily biodegradable (the key study reported 90.2% degradation in 28 days, meeting the 10-day window), and has an estimated octanol-water partition coefficient of log Kow = 7.95. Therefore, the substance has been classified as Category Chronic 3.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
