- Interpretation of results:
- GHS criteria not met
- Conclusions:
- There was no evidence of a positive reaction in animals after challenge treatment with Reaktiv-Rot F-66813 FW in the present study.
According to the classification criteria of Directive 83/467/EEC, Reaktiv-Rot F-66813 FW is not sensitizing in the guinea pig maximization test and therefore not subject to labelling requirements. - Executive summary:
The skin sensitizing potential of Reaktiv-Rot F-66813 FW was examined in Pirbright-White guinea pigs with the maximization test.
Intradermal and dermal induction as well as the dermal challenge treatment were performed using 5% Reaktiv-Rot F-66813 FW in 0.9% NaCl.solution.
Based on the results of the present study, Reaktiv-Rot F-66813 FW is not sensitizing and not subject to labelling requirement.
Reference
Signs of irritation during induction:
Administration of test substance in physiological saline solution led to
reddening and edema at the adminstration site. All test substance
treated sites were reddish stained by the test compound.
Evidence of sensitisation of each challenge concentration:
none
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not sensitising)
- Additional information:
Sensitisation was assessed using the Magnusson and Kligman sensitisation assay. During the induction phase of the study, no irritation reactions were noted in both control and test groups. All sites treated with the test substance were stained; therefore redness etc could not be properly evaluated.
On the basis of the results, the substance cannot be considered to be a skin sensitiser.
Respiratory sensitisation
Endpoint conclusion
- Additional information:
The registered chemical is a reactive dye. For this class of dyes it was generally agreed between the members of the Ecological and Toxicological Association of Dyes and Organic Pigments Manufacturers (ETAD) that a possible risk for respiratory sensitisation for workers exists at high exposure. However the following should be noted:
1) For the substance no history of respiratory problems, such as occupational asthma, is associated with the manufacture and use of the specific substance.
2) Due to the granular form or the proper de-dusting of the substance (spay dried in closed system from aqueous solution directly after synthesis) no risk for inhalative exposure arises.
The potential to cause respiratory sensitisation is therefore not considered to be applicable for this substance.
No evidence of respiratory sensitisation was noted in any of the studies conducted, and it is proposed that the substance is not a respiratory sensitiser.
Migrated from Short description of key information:
Not assessed. No evidence of respiratory sensitisation was noted in any of the studies conducted, and it is proposed that the substance is not a respiratory sensitiser.
Justification for classification or non-classification
The above study has been ranked reliability 1 according to the Klimish et al system. This ranking was deemed appropriate because the studies were conducted to GLP an in compliance with agreed protocols. Sufficient dose ranges and numbers are detailed; hence it is appropriate for use based on reliability and animal welfare grounds.
The above results triggered no classification under the Dangerous Substance Directive (67/548/EEC) and the CLP Regulation (EC No 1272/2008). No classification for sensitisation effects is therefore required.
