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
FAT 40147 can be considered to be neither readily nor inherently biodegradable.
Additional information
For assessment of the biodegradability of FAT 40147, two studies evaluating inherent biodegradability / biological elimination are available. Further, additional studies investigating BOD5 (Biolological Oxygen Demand) and COD (Chemical Oxygen Demand) of the substance are also available.
In a key study (1982) with FAT 40147, 10 % biological elimination was reported over 31 days. In a supporting study (1981), 37 % biological elimination was reported over 31 days. Based on these results, FAT 40147 can be considered to be not inherently biodegradable.
In the key studies for BOD5 and COD (1983), the BOD5 was 0 mg O2/g and COD was 1016.7 mg O2/g, hence giving a BOD5/COD ratio equal to 0, indicating substance to be not rapidly biodegradable. Similarly in other supporting studies conducted in 1981 and 1982, the BOD5/COD ratio was <0.5, again supporting the conclusion that FAT 40147 is not rapidly biodegradable.
Based on the above discussion, FAT 40147 can be considered to be neither readily nor inherently 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.
