No irritation and no signs of systemic toxicity were observed in any of the animals.
No mortality occurred and no clinical signs of systemic toxicity were observed in the animals of the main study. Body weights and body weight gain of experimental animals remained in the same range as controls over the study period.
All auricular lymph nodes of the animals of the experimental and control groups were considered normal in size.
No macroscopic abnormalities of the surrounding area were noted for any of the animals.
Mean DPM/animal values for the experimental groups treated with test item concentrations 2, 15 and 30% were 899, 780 and 584 DPM, respectively. The mean DPM/animal value for the vehicle control group was 911 DPM. The SI values calculated for the item concentrations 2, 15 and 30% were 1.0, 0.9 and 0.6, respectively.

Maximum concentration not causing irritating effects in preliminary test: 100 %
Signs of irritation during induction:
No signs of irritation were recorded, there were no effects observed. For the first stage of induction the highest concentration applicable as intradermal injection (2 g/8 ml) was chosen.
Evidence of sensitisation of each challenge concentration: none
Other observations: none

Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not sensitising)
- Additional information:
No skin sensitisation data for the substance reaction mass of amines, hydrogenated tallow alkyl and azelaic acid and lithium hydroxide is available.
However, a skin sensitisation study using guinea pigs was conducted according to OECE 406 method on reaction mixture of hydrogenated tallow alkyl amines with sebacic acid and lithium hydroxide (BIOSERVICE SCIENTIFIC LABORATORIES, 1999). No positive responses were observed after the challenge exposure, which was further confirmed by a reduced local lymph node assay (rLLNA) of the single (high) dose group (≥10%) and a concurrent negative control group. No evidence of sensitisation or irritation were detected and the substance was not considered classifiable.
This endpoint for dilithium azelate has been filled based on read across to a substance in the same category (dilithium adipate). Dilithium adipate (C6) was subjected to a Local Lymph Node Assay (LLNA) in mice according to OECD Guideline 429 (Latour 2015). This substance was chosen as it represented the potential worst case substance from the category ‘dilithium salts of linear (unbranched) dicarboxylic acids with hydrocarbon chain lengths of 6, 9 and 10’ since it had the highest relative lithium content and the lowest carbon chain length. Dilithium adipate was a non-sensitiser under the conditions of the test, with the highest Stimulation Index of 1.0 at 2% concentration in acetone/olive oil, with the EC3 value being >30% (the highest concentration tested).
Respiratory sensitisation
Endpoint conclusion
- Endpoint conclusion:
- no study available
Justification for classification or non-classification
Negative results were produced in the studies with two read across substances, dilithium azelate and reaction mixture of hydrogenated tallow alkyl amines with sebacic acid and lithium hydroxide.
Therefore, no classification is considered relevant for this endpoint for substance reaction mass of amines, hydrogenated tallow alkyl and azelaic acid and lithium hydroxide.
