Biodegradation in water: Screening tests
One key study according to OECD Guideline 301 D the test item attained 63% degradation after 28 days. Regarding REACH the substance can be considered as readily biodegradable, because the test item is a multi constituent substance.
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). The results of these studies demonstrate a reduction of the biodegradability with increasing of the chain length.
In two supporting studies according to OECD 302 B no biodegradation was found. Adsorption to sludge after 3 hours was > 20% respectively > 80%. In both studies the initial test substance concentration was above the water solubility.
Biodegradation in water and sediment: simulation tests
Waiving according to "column 2" in Annex VIII and IX of REGULATION (EC) No 1907/2006 (CSA does not indicate need for further investigations). The Substance is readily biodegradable.
Biodegradation in soil
Waiving according to "column 2" in Annex IX of REGULATION (EC) No 1907/2006 (CSA does not indicate need for further investigations). The Substance is 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.
