Description of key information

Additional information

Fatty acids lanolin, di, tri- and tetraesters with pentaerythritol and rape fatty acid achieved degradation rates of 28.5% (based on CO2 evolution, OECD 301B) at a concentration of 11.6 mg test material/L and 45.1% at a concentration of 23.2 mg test material/L. The substance is therefore not readily biodegradable according to OECD criteria.

In the same study, the toxicity control achieved a degradation rate of 85.5% after 14 d. The substance is therefore considered not inhibitory to microorganisms.
