Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Hydrolysis
Liquid chromatography with a mass spectrometer is used to determine the hydrolysis rate of the test substance.
With LC/MS a direct method is used to measure the amounts of Mono-and Diester, which will remain after incubation in case of hydrolysis. No decreases > 10% of Mono- and Diester have been detected at pH 7 and 9. At pH 4 the results are in the range of uncertainness of the measuring method; at pH 2 the expected hydrolysis takes place.
Therefore the hydrolysis rate is:
Hydrolysis rate: no hydrolysis observed at pH 7 and 9
Hydrolysis approx. 10% at pH 4*
Hydrolysis observed > 10 % at pH 2
*Due to the relative high uncertainty of the analysis method, a clear statement "higher or lower" than 10% is not possible.
Biodegradation in water: Screening tests
In one Key study the test item was determined with natural river water inoculum over a test period of 60 days in an Enhanced Modified Sturm Test according to the OECD Guideline 301 B and ECHA. As result one replicate shows a biodegradation of 79 %, whereas the both other replicates did not reach pass level of 60%. The test item is classified as not persistent in natural environmental media. In a second key study according OECD Guideline 301 B the test item shows biodegradation rates of 33 % after 28 days. Under this test conditions the test item is classified as not readily biodegradable in the 10-day-windows and within 28 days.
Two supporting studies with the read across substance Phosphoric acid, hexadecyl ester, potassium salt showed a degradation of 54% (OECD 301 F) and 37% (OECD 310). One supporting study with read across substance Phosphoric acid, octadecyl ester showed a degradation of 4-5% (OECD 301 F) and one supporting study with Phosphoric acid, octadecyl ester, potassium salt showed a degradation of 3% (OECD 301 E). One supporting study with the read across substance Phospshoric acid, dodecyl ester showed a biodegradation of 93 % (OECD 301 D). The results of these studies demonstrate a reduction of the biodegradability with increasing of the chain length.
Transport and distribution
Waiving according to "column 2" in Annex VIII and IX of REGULATION (EC) No 1907/2006. The study need not to be conducted because based on the physicochemical properties the substance can be expected to have a low potential for adsorption (Log Kow < 3).
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).
