REPORTING FORMAT FOR THE ANALOGUE APPROACH
1. HYPOTHESIS FOR THE ANALOGUE APPROACH: The analogue approach covers the substance Ultramarine Blue (EC nº 701-340-9) and the substance Ultramarine Violet (EC nº 701-186-2).The analogue Ultramarine Blue shares the same structure (Sodalite-type structure (SOD-Zeolite)) with the substance Ultramarine Violet. Therefore, they are expected to be toxicologically equivalent.
2. SOURCE AND TARGET CHEMICAL(S) (INCLUDING INFORMATION ON PURITY AND IMPURITIES) Ultramarine blue, C.I. Pigment blue 29, EC number: 701-340-9;
Ultramarine Violet, C.I. Pigment Violet 15, EC number: 701-186-2.
No relevant impurities.
3. ANALOGUE APPROACH JUSTIFICATION: The analogue approach covers the substance Ultramarine Blue (EC nº 701-340-9) and the substance Ultramarine Violet (EC nº 701-186-2).The analogue Ultramarine Blue shares the same structure (Sodalite-type structure (SOD-Zeolite)) with the substance Ultramarine Violet. Therefore, they are expected to be toxicologically equivalent.

The analogue approach covers the substance Ultramarine Blue (EC nº 701-340-9) and the substance Ultramarine Violet (EC nº 701-186-2).


 


The analogue Ultramarine Blue shares the same structure (Sodalite-type structure (SOD-Zeolite))p with the substance Ultramarine Violet. Therefore, they are expected to be toxicologically equivalent.


 


Based on the experimental results obtained with the analogue, the read-across approach is applied and the LC50 (96 h) for the substance Ultramarine Violet is considered to be >90 mg/L.

Validity criteria fulfilled:
not applicable
Conclusions:
Based on the experimental results obtained with the analogue, the read-across approach is applied and the LC50 (96 h) for the substance Ultramarine Violet is considered to be >90 mg/L.
Executive summary:

Based on the experimental results obtained with the analogue, the read-across approach is applied and the LC50 (96 h) for the substance Ultramarine Violet is considered to be >90 mg/L.

Description of key information

Read-across from analogue: key study according to OECD Test Guideline 203. The result was as follows: LC50 (96h) > 90 mg/L

Key value for chemical safety assessment
