Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
Biodegradation of retinyl palmitate was determined according to EU Directive 79/831/EEC Annex V part C and OECD Guideline 301 F using domestic, activated sludge as inoculum. The result showed a degradation rate of 40 – 60% after 28 days of exposure. Therefore, the test substance is partly or moderately biodegradable. Comparable degradation rates are expected for biodegradation in surface water, sediment and soil. However, with high probability retinyl palmitate will be used as a food source for bacteria. In addition, the degradation products retinol and palmitic acid are readily biodegradable; furthermore, both substances are natural nutrients. Therefore, simulation studies on biodegradation of retinyl palmitate in this compartments are not provided.
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.
