Description of key information

Data waiving in accordance with REACH Annex IX, 9.4, Column 2

Key value for chemical safety assessment

Additional information

Data waiving in accordance with REACH Annex IX, 9.4, Column 2: As the substance is ready biodegradable, not assumed to be highly adsorptive to soil (log Kow < 3, no other indications of high adsorption) and showed no aquatic toxicity (tested up to 100 mg/L), the substance was assigned to soil hazard category 1 according to the ITS described in ECHA Guidance R.7c. As the substance is not classified according to Regulation (EC) No 1272/2008, no exposure assessment is performed as part of the chemical safety assessment laid down in REACH Article 14(4). No toxicity testing is proposed by the registrant, because there is no need to investigate further the effects of the substance and/or degradation products on terrestrial organisms. Further, as the substance was non-toxic to STP microorganisms (OECD 209 no effects up to 100 mg/L; IC50Tetrahymena = 18 g/L), the potential for toxicity to soil micro-organisms is assumed to be low.
