Readily biodegradability:

The substance is considered not readily biodegradable since 2.7% (100 mg/L) of the test item degraded within 28 days, 4.9% (25 mg/L) within 28 days (OECD 301F). The toxicity control showed that the test item SymHelios® 1031 can be identified as non-toxic in a ready biodegradability test.


The substance does not undergo hydrolysis. The half-life of the substance is estimated > 1 year (OECD 111).

Adsorption/Desorption screening:

According to the McCall classification scheme of soil mobility potential SymHelios® 1031 is classified from slight mobile (isomere 1 Koc = 3776) to immobile (isomere 2 Koc = 5342) (OECD 121).
