Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A study with the analogue tetradecyl myristate showed this ester to be readily biodegradable: 67% (BOD) after 28 d (OECD 301C). Estimation using the QSAR program BIOWIN (v4.10) indicated that also tetradecyl laurate is readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Reference is made to a study investigating the biodegradation of the analogue tetradecanoic acid, tetradecyl ester (CAS 3234-85-3). The study was performed according to OECD 301C (GLP) under aerobic conditions using a mixture of activated sludge from STP with freshwater from rivers and lakes, marine water and marine sediment as inoculum (Ministry of Economy, Trade and Industry, Japan, 1992). The test substance degraded to an extent of 67% (BOD) after 28 d and can be considered as readily biodegradable according to the OECD criteria (biodegradation is > 60% after 28 d, no 10-day window required). Performing QSAR calculations according to the program BIOWIN (v.4.10) confirmed that tetradecyl laurate can be expected to be readily biodegradable.
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.
