EC number: 947-269-9 | CAS number: -
In a ready biodegradation study performed according to OECD Guideline 301 C, the test item was tested at concentrations of 100 mg/L and the inoculum was activated sludge (30 mg/L). The degradation of the test material was assessed by the determination of the oxygen consumption.
At 100 mg/L test concentration, 85 % degradation (biochemical oxygen demand) was reached in 2 weeks.
Under the test conditions, the test item was readily biodegradable.
At 100 mg/L test concentration, 90% degradation (biochemical oxygen demand) was reached in 4 weeks.
Please see the attached documents.
The ready biodegradation property of the substance was investigated using QSAR approach with Biowin v4.10 plug-in from EPISUITE v4.1 from US EPA.
It's expected that the test item is readily biodegradable.
At 100 mg/L test concentration, 94% degradation (biochemical oxygen demand) was reached in 2 weeks.
At 100 mg/L test concentration, 97% degradation (biochemical oxygen demand) was reached in 2 weeks.
Based on a weight of evidence approach with data on constituents, the registered substance can be regarded as readily biodegradable.
The registered substance is a Natural Complex Substance (NCS) with a well-defined composition.
Major constituents of the registered substance represent ca. 92% of the NCS based on a typical composition.
All these constituents have been found to be readily biodegradable. Full details can be found in the table 1 of the document attached in section 13.2: "data on constituents for e-fate and ecotox endpoints".
Therefore, based on a constituents approach, it is possible to consider that the registered substance is readily biodegradable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
