Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Key value for chemical safety assessment
Skin sensitisation
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not sensitising)
- Additional information:
Mean DPM/animal values for the experimental groups treated with test substance concentrations 10, 25 and 50% were 1190, 1050 and 802 DPM, respectively. The mean DPM/animal value for the vehicle control group was 671 DPM. The SI values calculated for the substance concentrations 10, 25 and 50% were 1.8, 1.6 and 1.2, respectively.
Since there was no indication that the test substance elicited a SI ≥ 3 when tested up to 50%, C. I. Pigment Violet 55 was not considered to be a skin sensitizer Mean DPM/animal values for the experimental groups treated with test substance concentrations 10, 25 and 50% were 1190, 1050 and 802 DPM, respectively. The mean DPM/animal value for the vehicle control group was 671 DPM. The SI values calculated for the substance concentrations 10, 25 and 50% were 1.8, 1.6 and 1.2, respectively. Since there was no indication that the test substance elicited a SI ≥ 3 when tested up to 50%, C. I. Pigment Violet 55 was not considered to be a skin sensitizer according to Regulation EC 1272/2008
Migrated from Short description of key information:
The in vivo LLNA study was performed according to OECD Guideline 429 and GLP principles.
Justification for selection of skin sensitisation endpoint:
One key study is available as well as a supporting study.
Respiratory sensitisation
Endpoint conclusion
- Endpoint conclusion:
- no study available
Justification for classification or non-classification
Based on the above results, the test substance should not be classified as a skin sensitizer according to Regulation EC 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
