Description of key information
The LC50 (14d) for 2-phenoxyethanol was determined as > 340 mg/kg DM in a toxicity test with Eisenia fetida.
Key value for chemical safety assessment
- Short-term EC50 or LC50 for soil macroorganisms:
- 340 mg/kg soil dw
Additional information
The key study investigated the toxicity of 2-phenoxyethanol (purity 99.9%) to earthworms (Eisenia fetida) according to OECD 207 (BASF SE, 2008). The clitellated adult earthworms were exposed for 14 days to test substance treated artificial soil. The LC50 after 14 days was determined to be >1000 mg/kg DM. -The percentage of organic carbon in the natural soil has not been corrected for. As the percent organic carbon was 10% and the agreed standard organic matter percent for tests is 3.4% a correction factor of 0.34 should be multiplied by all endpoints. Thus, the resulting EC50 (standard) is > 340 mg a.s./kg dry mass soil after 14 day
In a supporting study, the toxicity of 2-phenoxyethanol to earthworms was tested according to EU Guideline C.8 (Sasol Germany GmbH, 1994). Eisenia fetida were exposed to 1170 mg/kg waterfree test substance (purity 85.7%, contaminated with phenoxydiethanol) in waterfree substrate in a limit test. The LC0 based on mortality was determined as 1170 mg/kg soil dw.
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.
