Description of key information
The test item has a vapour pressure of <= 1.5*10-2 atm (<= 1.6*103 Pa; <= 16 mbar) at 20 °C and of <= 1.3*10-1 atm (<= 1.3*104 Pa; <= 131 mbar) at 50 °C (the calculation is based on the lowest possible boiling temperature; Grain Watson estimation).
Key value for chemical safety assessment
Additional information
A GLP study was conducted. The study in accordance with the OECD Guideline for the Testing of Chemicals 104: "Vapour pressure".
The practical test performance was based on the in-hause test procedure VTA(S)31X07001.01: "Determination of the vapour pressure curve of solid and liquid substances by means of DSC".
The experimentally determined vapour pressure of the test item at 20 °C of » 1000 mbar is not in the recommended range of 1 to 1000 mbar for DSC-measurements
Therefore an estimation procedure according to the test method A.4. "Vapour pressure" as described in the Council Regulation (EC) No 440/2008 of 30 May 2008 laying down test
methods pursuant to Regulation (EC) No 1907 / 2006 of the European Parliament and of the Council on the Registration, Evaluation, Authorization and Restriction of Chemicals
(REACH) similar to the test method OECD Guideline 104 "OECD Guideline For The Testing Of Chemicals, adopted by the Council on 23 March 2006, Vapour Pressure" (see Appendix
1, Estimation Method, newest version (Robert S. Boethling, Donald Mackay, Handbook of Property Estimation Methods for Chemicals, Lewis Publishers, year of publication 2000,
Cap. 3 - Vapour Pressure, Grain-Watson Method, p. 53 - 65) was used.
The test item has a vapour pressure of <= 1.5*10-2atm (<= 1.6*103Pa; <= 16 mbar) at 20 °C and of <= 1.3*10-1atm (<= 1.3*104Pa; <= 131 mbar) at 50 °C (the calculation is based on the lowest possible boiling temperature; Grain Watson estimation).
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).
