Description of key information
Additional information
In a hydrolysis study with phenoxypropanol no hydrolysis was observed at 50°C and pH 4, 7 and 9. Biodegradation studies in freshwater and in soil are available for phenoxypropanol. Phenoxypropanol was shown to be readily biodegradable according to OECD Guideline 301 F (Ready Biodegradability: Manometric Respirometry Test). In the manometric respirometry test (OECD GL 301F) the time required to achieve 10% degradation of phenoxypropanol was 5.1 days, while the average extent of biodegradation at the end of the 10 day-window was 72%. The formation of CO2 reached 61% CO2, suggesting the extensive mineralisation of phenoxypropanol. Rapid biodegradation of phenoxypropanol was observed in two different sandy loam soils under aerobic conditions at 25±2 Deg. C Based on the existing biodegradation data in freshwater and soil and considering low potentential for adsorption to sediment. No further biodegradation testing in water and sediment is required. According to REACH Annex IX requirements, sediment simulation testing shall only be considered for substances with a high potential for adsorption to sediment, hence no further simulation tests in water and sediment are required for phenoxypropanol.
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.
