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 the meta-isomer of the dye Reactive Yellow 095, where the sulphonate group is bound at the meta-position of the amino benzene moiety. The source chemical is the reaction mass of both the meta-isomer and the para-isomer of Reactive Yellow 095.
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 Yellow 095 meta/para (CAS# --- / EC# 944-218-2)
Target: Reactive Yellow 095 meta (CAS# 84045-63-6 / EC# 281-865-3)
3. ANALOGUE APPROACH JUSTIFICATION
see attachment under 4.12 Auto flammability
Reason / purpose:
read-across source
Test procedure:
burning rate test: preliminary screening test
Burning time:
0 s
Remarks on result:
substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period
Interpretation of results:
not classified based on GHS criteria
Conclusions:
No ignition was observed throughout the course of the test. The test item should be considered as not highly flammable.
Executive summary:

The flammability of the source substance was evaluated in a study conducted according to EU Method A.10. The substance did not ignite or propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period. Hence, the test item should be considered as not highly flammable. The structurally related target substance should hence also be considered as not

highly flammable.

None

Interpretation of results:
GHS criteria not met
Conclusions:
No ignition was observed throughout the course of the test. Hence, the test item FAT 40000 should be considered as not highly flammable.
Executive summary:

The flammability of the test substance was evaluated in a study conducted according to EU Method A.10. The substance did not ignite or propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period. Hence, the test item FAT 40000 should be considered as not highly flammable.

Description of key information

The substance is not highly flammable.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

The flammability of the source substance was evaluated in a study conducted according to EU Method A.10. The substance did not ignite or propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period. Hence, the test item should be considered as not highly flammable. The structurally related target substance should hence also be considered as not

highly flammable.

Justification for classification or non-classification

No ignition was observed throughout the course of the test.

The test item should be considered as not highly flammable.
