Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The substance is readily biodegradable according to OECD criteria.

The half-life in soil is 1.3 days.

Key value for chemical safety assessment

Additional information

In accordance with Regulation (EC) No 1907/2006, Annex IX, Section, Column 2, soil simulation testing does not need to be conducted if the substance is readily biodegradable. NOP is readily biodegradable (81% in 28 d, OECD 301F, BASF AG, 1992; see IUCLID Ch. 5.2.1). Therefore, no soil simulation study will be provided.

However, a study on the degradability in soil is available. The study was performed according to EPA guideline subdivision N, section 161-2 (Saxena, 1992). The substance was degraded to 61.5% CO2/ThCO2 after 43 d ina sandy loam. Transformation products were not specified. The half-life was determined to be 1.3 days.
