Key value for chemical safety assessment

Skin sensitisation

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not sensitising)
Additional information:

A LLNA/IMDS was carried out in female NMRI mice after epicutaneous application of formulation

containing 0%, 2 %, 10 %, or 50 % of the test item Diazokomponente Rot B for 3 consecutive days

onto both ears of the animals.

Diazokomponente Rot B showed no sensitizing potential in the modified Local Lymph Node Assay (IMDS) in female NMRI mice after dermal application of up to and including a 50 % concentration. Additionally, no indication for a non-specific(irritant) activation by the test item was detected The positive control hexyl cinnamic aldehyde (CAS-No. 101 -86 -0) was functional for each parameter (Bayer 2011)..
