Hydolysis

Two different analytical methods are used to determine the hydrolysis rate of the substance.

With 31P-NMR spectroscopy a direct method is used to measuring the change of the integration of the ester signals.

With Ionic Liquid Chromatography an indirect method by measuring the increasing phosphate concentration is used.

With the previous results of 3,P-I\IMR spectroscopy an Ionic Liquid Chromatography the hydrolysis rate of the substance is:

Hydrolysis rate: no hydrolysis observe

Biodegradation in water: Screening test

 

In two Key studies according OECD Guideline 301B and 301F the ready biodegradation was reported. Two supporting studies shows also a biodegradation butthe degradation rate was < 60 % of the ThOD after 28 days.

 

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 VIII and IX of REGULATION (EC) No 1907/2006 (CSA does not indicate need for further investigations). The Substance is readily biodegradable.

Bioaccumulation

Waiving according to "column 2" in Annex IX of REGULATION (EC) No 1907/2006. The study need not to be conducted because the substance has a low potential for bioaccumulation. The Log Kow is < 3.

Adsorption / desorption

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). The Substance is readily biodegradable.
