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 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 item is >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 similar results, and will not show auto-ignition up to 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 of the source substance could not be determined as no auto-ignition occurred up to 550 °C. The structurally related target substance will show similar results, and will not show auto-ignition up to 550°C.
