Description of key information

The physical and chemical properties of the three substances in the read-across family (BADGE-EDA, BADGE-DETA and BADGE-TETA) have been determined for REACH Registration purposes. Specific endpoints for physical and chemical data will be used for registration of each substance.

The appearance of BADGE-TETA was determined as very pale green/yellow translucent, homogeneous, transparent, soft solid at 20.0 ± 0.5 ºC, visually assessed using a method designed to be compatible with Methods 830.6302 and 830.6303 of the OCSPP guidelines, August 1996.

The melting/freezing temperature was determined as 48 ± 3 °C (321 ± 3 K), using pour point method, designed to be compatible with Method A.1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.

Boiling point was determined with decomposition from approximately 360°C (633 K) at102.6 kPa. As the test item decomposed, no value for boiling point could be determined, by differential scanning calorimetry, designed to be compatible with Method A.2 Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.

The corresponding relative density was calculated to be 1.12, using the pycnometer method, designed to be compatible with Method A.3 Relative Density of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 109 of the OECD Guidelines for Testing of Chemicals, 02 October 2012.

The vapor pressure of BADGE-TETA has been determined to be less than 4.0 x 10-3 Pa at 25 °C, using the vapor pressure balance method, designed to be compatible with Method A.4 Vapour Pressure of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 104 of the OECD Guidelines for Testing of Chemicals, 23 March 2006.

Partition coefficient was determined to be 1.97 at 24.0 ± 1.0°C, log10 Pow 0.292, using the shake-flask method, designed to be compatible with Method A.8 Partition Coefficient of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 117 of the OECD Guidelines for Testing of Chemicals, 13 April 2004.

Water Solubility; Miscible greater than 95% w/w, using an adapted flask method, designed to be compatible with Method A.6 Water Solubility of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 105 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.

Flash point of 229 ± 2°C, was determined using a closed cup equilibrium method designed to be compatible with Method A.9 Flash Point of Commission Regulation (EC) No 440/2008 of 30 May 2008.

An auto-Ignition Temperature (Liquids and Gases) of 406 ± 5 °C was determined for BADGE-TETA using a procedure designed to be compatible with Method A.15 Auto-Ignition Temperature (Liquids and Gases) of Commission Regulation (EC) No 440/2008 of 30 May 2008.

BADGE-TETA is not highly flammable, this was determined using a procedure designed to be compatible with Method A.10 Flammability (Solids) of Commission Regulation (EC) No 440/2008 of 30 May 2008.

Explosive properties were predicted negative based on the chemical structure of the test item, using a procedure designed to be compatible with Method A.14 Explosive Properties of Commission Regulation (EC) No 440/2008 of 30 May 2008.

Oxidising properties were predicted negative based on the chemical structure of the test item, using a procedure designed to be compatible with Method A.17 Oxidising Properties (Liquids) of Commission Regulation (EC) No 440/2008 of 30 May 2008.
