Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
The test substance FAT 40865/A TE is a black colored powder at 20°C temperature.
The melting point of test item FAT 40865/A TE was determined to be greater than 300°C.
The boiling point of test item FAT 40865/A TE was determined to be greater than 300°C.
Based on the results of the study, the density of FAT 40865/A TE was determined to be 0.611 g/mL with an RSD of 0.03% at thermostatic conditions maintained at 20°C.
The limit value vapor pressure of the test item, FAT 40865/A TE was calculated to be 0.00072 Pa (7.28×10-3 Pa) at 25 °C.
Partition coefficient of FAT 40865/A TE was determined in n-octanol:distilled water. The ratio of n‑octanol:distilled water used in the study was 1:1, 2:1 and 1:2. FAT 40865/A TE was determined to have a mean Kow of 1132 and log10Kow of 3.05±0.002 at 23.4°C.
Mean water solubility of the test item, FAT 40865/A TE, in double distilled water was found to be 175.76 g/l at 20 °C.
FAT 40865/A TE has got no ignition nature. No change in color of the test item and no burn, glows and smoulders were observed in the tray upto 300 °C.
The results of the study revealed that the test item, FAT 40865/A TE was non-flammable.
The exothermic decomposition energy released is found to be 98 J/g which is far below the critical trigger level of 500 J/g. Therefore, the test item FAT 40865/A TE is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) 1272/2008.
Based on expert judgment with reference to chemical groups associated with oxidising properties (adapted from Bretherick’s Handbook of Reactive Chemical Hazards 6th Ed., 1999, Butterworths, London), the test item does not contain compounds with any structures or groups associated with oxidizing properties. Therefore, based on the composition oxidizing properties of the test item are not probable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
