Description of key information
Additional information
For several environmental fate, ecotoxicity and toxicity endpoints, read-across to an analogue substance is performed. In the following, a comparison of phys.-chem. data of the substance registered with the analogue substance is given, as supporting data for the applicability of the proposed read across approach.
| Endpoint | Substance registered | Analogue substance |
| Appearance | solid | solid |
| Melting point | Decomposition ≥ 150 °C | Decomposition ≥ 120 °C |
| Boiling point | Decomposition ≥ 150 °C | Decomposition ≥ 120 °C |
| Density D4(20) | 1.27 | 1.24 |
| Granulometry | MMD = 33.4 µm | Could not be determined, as substance forms a clump |
| Vapour pressure (25 °C) | 3.92 x 10E-31 Pa | 2.4 x 10E-28 Pa |
| Partition coefficient (log Pow) | -1.4 (23 °C) | -2 (20 °C) |
| Water solubility | > 677 g/L (23 °C) | 430.5 g/L (20 °C) |
| Surface tension (20 °C) | 62 mN/m | 44.9 mN/m |
| Auto flammability (A.16) | Not auto-flammable | Not auto-flammable |
| Flammability | Not highly flammable (A.10); Not pyrophoric; No spontaneous ignition in contact with water | Not highly flammable (A.10); Not pyrophoric; No spontaneous ignition in contact with water |
| Explosiveness | Non explosive | Non explosive |
| Oxidising properties | Non oxidising | Non oxidising |
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
