Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- REPORTING FORMAT FOR THE ANALOGUE APPROACH
1. HYPOTHESIS FOR THE ANALOGUE APPROACH
This read-across is based on the hypothesis that the source and the target substance have very similar physicochemical and (eco)toxicological properties because their chemical structures are nearly identical. An analogue approach has thus been employed. The target substance is Reactive Red 24 carrying a methyl group, while the source chemical is Reactive Red 24:1 carrying an ethyl group.
The presence of sulphonate groups make both dyes highly water soluble and therefore less critical for human health and environmental issues. Based on their chemical similarity, similar properties are expected in both humans and the environment.
2. SOURCE AND TARGET CHEMICAL(S)
Source: Reactive Red 24:1 (CAS# 72829-25-5 / EC# 276-911-4)
Target: Reactive Red 24 (CAS# 70210-20-7 / EC# 274-417-3)
3. ANALOGUE APPROACH JUSTIFICATION
see attachment under 4.12 Auto flammability - Reason / purpose for cross-reference:
- read-across source
- Relative self-ignition temperature:
- > 550 °C
- Remarks on result:
- no self ignition observed under the test conditions
- Conclusions:
- The auto-ignition temperature of the test substance could not be determined as no auto-ignition occured up to 550 °C.
- Executive summary:
The determination of the auto-ignition temperature of the source substance was performed in a study conducted according to EU Method A.15. However, the auto-ignition temperature could not be determined as no auto-ignition occurred up to 550 °C. The structurally related target substance will show the same behaviour and will not auto-ignite either.
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2016
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Justification for type of information:
- None
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- Deviations:
- no
- Principles of method if other than guideline:
- None
- GLP compliance:
- no
- Specific details on test material used for the study:
- None
- Key result
- Relative self-ignition temperature:
- > 550 °C
- Remarks on result:
- no self ignition observed under the test conditions
- Conclusions:
- The auto-ignition temperature of FAT 40034 could not be determined as no auto-ignition occured up to 550 °C.
- Executive summary:
The determination of the auto-ignition temperature of FAT 40034 was performed in a study conducted according to EU Method A.15. However, the auto-ignition temperature of FAT 40034 could not be determined as no auto-ignition occurred up to 550 °C.

Description of key information
The auto-ignition temperature of the test substance could not be determined as no auto-ignition occured up to 550 °C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 550 °C
Additional information
The determination of the auto-ignition temperature of the source substance was performed in a study conducted according to EU Method A.15. However, the auto-ignition temperature could not be determined as no auto-ignition occurred up to 550 °C. The structurally related target substance will show the same behaviour and will not auto-ignite either.
