Additional information

Stability

Hydrolysis

The test item was found to be stable in the preliminary test. With respect to the guidelines a half-life of ≥ 2 year and a degradation rate of 0 min-1 could be assumed for environmental typical temperature conditions.

 

Biodegradation

Biodegradation in water: screening test

The test substance was biodegraded by 38 % over 28 days. The test substance is classified as not readily but inherently biodegradable according to the OECD criteria.

 

Transport and distribution

Adsorption/desorption

In accordance with column 2 of REACH Regulation (EC) No 1907/2006 Annex VIII no study on adsorption/desorption has to be conducted as the partition coefficient log Pow of the test substance was determined to be log Pow = 2.81 for isomer 1 and 2.98 for isomer 2 at 23.6 °C.

 

Henry´s Law constant

The Henry's law constant was calculated to be 30.22 Pa m3/mol (calculated by HENRYWIN v3.20).
