- Executive summary:
The acute dermal toxicity of the test substance was assessed in a GLP-compliant study following OECD guideline 402. The test article was administered to five rats of each sex by dermal application at 2000 mg/kg body weight for 24 hours. Animals were subjected to daily observations and weekly determination of body weight. Macroscopic examination was performed after terminal sacrifice. No mortality occurred. No signs of acute dermal toxicity were observed in this study. The mean body weight gain during the observation period was within the range expected for rats used in this type of study. No abnormalities were found at macroscopic post mortem examination of the animals. The dermal LD50 value of the test substance in rats was established to exceed 2000 mg/kg body weight.

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, if available.
Acute oral toxicity
CAS 80584-92-5:
In an acute oral toxicity study, groups of Wistar rats (5/sex) were given a single oral dose of the diluted test substance at a dose level of 5000 mg/kg body weight in distilled water. The animals were then observed for 14 days. No mortality was observed in both male and female rats. Animals showed dyspnea, exopthalmus, ruffled fur, diarrhoea and a curved body position. All symptoms had been resolved by study day 11. During necropsy no treatment related changes were observed. A LD50 of above 5000 mg/kg bw was determined.
CAS 80584-91-4:
One key study is available where the acute oral toxicity of the triazine part was investigated. The study was performed in RAIf (SPF) (Ra 25) rats (5 animals per sex and dose) with a limit dose of 5000 mg/kg bodyweight according to OECD TG 401 (adopted 1981). No mortality occurred and no clinical signs were observed during the observation period (14 days). No necropsy findings were reported. In conclusion, the LD50 was determined to exceed 5000 mg/kg body weight.
CAS 102 -71 -6
In an acute oral toxicity study, 5 Sprague-Dawley rats/sex/dose were exposed to 200 - 6400 mg/kg bw TEA by gavage and observed for 7 days. The LD50 was determined to be 6400 mg/kg bw for males and females. No deaths occurred at doses of 5000 mg/kg bw or below. At 200 mg/kg bw, slight agitation was observed up to 4 hours after exposure; at higher doses unsteady, elevated respiration, anancasm to chew, apathy, and reduced grooming was noticed. Two days after exposure, no clinical signs were observed. Gross pathology did not reveal any abnormalities.
Acute dermal toxicity
CAS 80584-91-4
One GLP-compliant key study is available where the acute dermal toxicity of the test article was investigated. The study was performed in RAIf (SPF) rats (5 animals per sex and dose) with a limit dose of 2000 mg/kg bodyweight under semiocclusive conditions for 24 hours, according to OECD TG 402 (adopted 1987). No mortality occurred and no clinical signs were observed during the observation period (14 days). No necropsy findings were reported. In conclusion, the LD50 was determined to exceed 2000 mg/kg body weight.
CAS 102-71-6
In a dermal limit test, rabbits were treated with 2000 mg/kg body weight TEA on the intact or abraded skin and subsequently observed for a 14 -day period. The test substance was either derived from NH3 (92% TEA) or DEA (88% TEA), both containing approximately 6.5% DEA. Mild erythema was observed following exposure to TEA derived from NH3 on the intact or abraded skin, returning to normal on day 6. Moderate erythema was observed following exposure to TEA derived from DEA on the intact or abraded skin, returning to normal on day 10. No mortality was observed, hence the LD50 was > 2000 mg/kg body weight.
Acute inhalation toxicity
no data available
Conclusion
The test article is of very low acute toxicity. The test article itself
and its individual components, the triazine part and the amine, were not
acutely toxic when administered with high doses. No findings were
reported at necropsy. When given dermally, the triazin and the amine
compound did not produce toxic signs at the limit dose. The test article
is therefore considered to be not acutely toxic.
Justification for classification or non-classification
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 for acute oral toxicity under Regulation (EC) No 1272/2008.
