- Test item: Acid Orange 94 Refined
Alternative name: Disodium 5, 5’-[(1-methylethylidene)bis(4,1-phenyleneoxysulphonyl-2,1-phenyleneazo)]bis[6-aminonaphthalene-1-sulphonate]
CAS number: 70161-18-1
EC number: 274-354-1
Intended use: Industrial chemical
Appearance: Reddish brown crystals
Storage conditions: Room temperature (10 – 30C), in the dark
Lot number: 8009
Expiry/Retest date: 31 December 2019
Purity: 97% - Key result
- Relative self-ignition temperature:
- > 400 °C
- Remarks on result:
- no self ignition observed under the test conditions
- Conclusions:
- The test item has been determined to not have a relative self-ignition temperature below 400 °C.
- Executive summary:
The auto flammability of the test item was determined using a procedure designed to be compatible with Method A.16 Relative Self-Ignition Temperature for Solids of Commission Regulation (EC) No 440/2008 of 30 May 2008, in accordance with GLP.
Whilst heating the test item, no relevant exothermic reaction /self-heating of the sample was observed. On completion of the test, the test item was an expanded black, charred mass.
The test item has been determined to not have a relative self-ignition temperature below 400 °C.

The test item has been determined to not have a relative self-ignition temperature below 400 °C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 400 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
