Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not sensitising)
- Additional information:
The substance is a salt which is a reaction product of an acid (triazine compound, CAS 80584-91-2) and a base (triethaonoleamine, TEA, CAS 102-71-6) that retain their ionic character. Under aqueous conditions it is expected to be present in its dissociated form. Therefore, the individual components of the salt are assessed separately. Data on the salt itself are also provided.
CAS 80584-92-5:
In a dermal sensitisation study equivalent or similar to OECD guideline 406, guinea pigs (10/sex) were tested in a Freund´s complete adjuvant test. During the induction period, the animals received one injection every second day (except weekends) to a total of 10 intracutaneous injections of a freshly prepared 0.1% solution of the test substance in physiological saline. One control group was treated with the vehicle alone ("negative control"). On the first day, injections of 0.1 mL were administered onto the shaved skin of the right flank and the back, while on the following days a single intracutaneous injection was given into the back. During the second and third week of the induction period the test material was incorporated in a mixture of the normal vehicle with complete Bacto Adjuvant (vehicle : adjuvant = 1:1). Fourteen days after the last sensitizing injection, a challenge injection of 0.1 mL of a freshly prepared 0.1% solution of the test substance in physiological saline was administered onto the skin of the left flank. Twenty-four hours after each injection during the first week of the induction period and 24 hours after the challenge injection the reactions were recorded. Intradermal injections of the vehicle alone failed to induce sensitization. Three animals of the control group died during the rest period between challenge I and II. The death of all three animals must be considered to be unrelated to the treatment. No positive reactions were observed after the intradermal challenge injection or the occlusive epicutaneous application. The test substance is not considered as skin sensitising according to the results of this study.
CAS 80584-91-4:
The triazine compound's potential to cause sensitization after dermal exposure was assessed in a GLP-compliant maximization test with Dunkin Hartley guinea pigs according to OECD guideline 406. In this study, the test group animals received 15 % of the test item by intradermal induction as well as 40 % of the test item for epicutaneous induction one week later for 48 hours. 0.5 % carboxy methylcelluose served as vehicle. For intradermal induction, three pairs of injections (50% FCA; test item in vehicle; test item in vehicle plus 50% FCA) were given. In the absence of irritation at dose ranging, the animals were treated with 0.5 ml of 10% sodium lauryl sulphate (SLS) one day prior to epidermal induction treatment. Epidermal challenge was performed by occlusive application for 24 h two weeks later (40% in CMC). A control group was treated with adjuvant and the vehicle during the induction period. During the challenge period, the group was treated with the test compound. Following challenge reaction, no positive responses were noted in any animal of the test or control group. In conclusion, based on the result of this study, the test article is not considered to cause skin sensitization in guinea pigs.
CAS 102-71-6
The sensitising potential of TEA was investigated in a Guinea Pig Maximisation Test according to OECD TG 406 under GLP conditions. Based on the results of a pre-test, animals were dermally injected twice with 0.1 mL 2% TEA on day 1, followed by an epicutaneous induction (occlusive) with 0.5 mL undiluted TEA for 48 hours starting on day 9, and a dermal challenge (occlusive) with 0.5 mL 10% TEA for 24 hours on day 22. Dermal reactions were evaluated according to Draize 48 and 72 hours after the start of the dermal challenge. No clinical signs were noticed and all readings were negative.
Regarding the available human data, the positive reactions interpreted as allergic seem to be caused by exposure to TEA in cosmetics and/or topical therapeutic preparations possibly on damaged skin. The diagnosis of TEA contact sensitisation should therefore not be based on a positive patch test reaction alone but on a combination of history and – preferably – validation tests.
The negative experimental findings in animals and the level of exposure to TEA in the population, together with the low frequency of positive reactions to low TEA concentrations in patch-tested patients indicate a very low sensitisation potential in humans, and the risk of sensitisation to TEA on uncompromised skin seems to be very low.
Conclusion
The test article itself and its individual components, the triazine part and the amine, were not sensitizing in animal studies, therefore the test article is considered to be not sensitizing.

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation 1272/2008. As a result the substance does not need to be classified and labelled under Regulation (EC) No 1272/2008.
