At the end of the experiment the relative weight of the organs (heart, lungs, kidneys, liver, spleen, adrenal lang, testicles) of the animals assigned to the experimental group was higher than the relative weight of the organs of the animals assigned to the control group.
The clinical signs observed after the application of the test material was the pinkish coloration of the skin which derived from physiological standards. After the application of the test material and the autopsy no macroscopic pathomorfological changes were observed.
The LD50 of the substance for male rats over the period of 14 days is greater than to 5020 mg/kg b.w. (3514 mg/kg b.w. based on the active ingredient).

Additional information
The test substance was evaluated for its potential to cause acute toxicity in rats.
Acute Toxicity: Oral
The study was performed according to the OECD guideline 401, following oral administration of multiples doses to the rats. Mortality is observed in doses higher than 7.943 g/Kg. After 14 days of observation, rats showed weight loss in all the application doses. Clinical signs observed were : conjuntivitis, locomotion disorders due to ataxia, diarrhea, hypergie, hyperaesthesia and blue coloration of the skin.
The acute oral LD50 was determined to be 9476.1 mg/kg bw.
Acute Toxicity: Dermal
The evaluation of acute dermal toxicity has been performed according to the OECD guideline 402. No mortality occurred during the study.
After 14 days of the observation period, rats showed increase of body weight. At the end of the experiment the relative weight of the organs (heart, lungs, kidneys, liver, spleen, adrenal lang, testicles) of the animals assigned to the experimental group was higher than the relative weight of the organs of the animals assigned to the control group. The clinical sign observed after the application of the test material was the pinkish coloration of the skin which derived from physiological standards. After the application of the test material and the autopsy no macroscopic pathomorfological changes were observed.
Justification for classification or non-classification
According to the CLP Regulation (EC) No. 1272/2008, 3.1 Acute toxicity section, substances can be allocated to one of four toxicity categories based on acute toxicity by the oral, dermal or inhalation route according to numeric criteria. Acute toxicity values are expressed as (approximate) LD50 (oral, dermal) or LC50 (inhalation) values or as acute toxicity estimates (ATE).
The oral LD50 value was established to be 9476.1 mg/kg body weight, therefore the test substance is out of any classification limit for acute oral toxicity (oral acute toxicity Category 4: 300 < ATE ≤ 2000 mg/kg bw).
The dermal LD50 value was established to be higher than 5020 mg/kg body weight, which exceeded the highest CLP limit for classification (dermal acute toxicity Category 4: 1000 < ATE ≤ 2000 mg/kg bw).
In conclusion, using the data obtained from oral and dermal acute toxicity, it is possible to conclude that the test substance is not classified for acute oral toxicity and acute dermal toxicity, according to the CLP Regulation (EC) No. 1272/2008.
