- No mortality occurred.
- Clinical signs:
- other: Systemic effects: No systemic clinical signs were observed during clinical examination in male and female. Local effects: Male: moderate erythema (grade 2) was seen in four male animals from study day 1 until study day 3 and persisted in one of these ani
- Gross pathology:
- No macroscopic pathologic abnormalities were noted in any animal examined on the last day of observation (5 males and 5 females).
- Conclusions:
- In an acute dermal toxicity study (Limit Test), young adult Wistar rats (5 males and 5 females) were dermally exposed to a single dose of 2000 mg/kg bw of the undiluted test item 3-[[3-[[(2-cyanoethyl)amino]methyl]-3,5,5- trimethylcyclohexyl]amino]propiononitrile to the clipped application site (dorsal and dorso-lateral parts of the trunk and covered by semi-occlusive dressing during the 24-hour exposure period. The application area comprised at least 10% of the total body surface. The animals were observed for 14 days.
- No mortality occurred
- No signs of systemic toxicity were observed
- The following test item-related local skin effects were recorded during the course of the study, local effects occurred within 10 days after application:
- Well-defined erythema (grade 2)
- Incrustations
- Scaling
- All animals gained weight in a normal range throughout the study period.
- No macroscopic pathologic abnormalities were noted in any animal examined at the end of the study (5 males and 5 females).
Accordingly, the acute dermal median lethal dose (LD50) was determined to be LD50, dermal, rat > 2000 mg/kg bw - Executive summary:
Under the conditions of this study the median lethal dose (LD50) of 3-[[3-[[(2-cyanoethyl)amino]methyl]-3,5,5- trimethylcyclohexyl]amino]propiononitrile after dermal application was found to be greater than 2000 mg/kg bw in male and female rats.

Additional information
Acute toxicity oral:
The study was performed to assess the acute toxicity following oral administration of the test item in Wistar rats. Single doses of 2000 and 500 mg/kg body weight of test material preparations in olive oil Ph.Eur./DAB were given to 3 administration groups of three fasted female animals, each, (2000 mg/kg in 3 females, 500 mg/kg in 6 females) by gavage in a sequential manner. Two animals of the 2000 mg/kg administration group were found dead, one on study day 1 and one on day 8. No mortality occurred in the 500 mg/kg administration groups. Clinical observation in the 2000 mg/kg bw administration group revealed impaired general state, dyspnoea, staggering, tremor, piloerection, smeared fur, salivation and red clammy snout. Findings were observed from hour 0 until including study day 9 after administration. No clinical signs and findings were observed in the 500 mg/kg bw administration groups. The body weight of the surviving animal of the 2000 mg/kg bw administration group and the mean body weights of the animals of the 500 mg/kg bw administration groups increased throughout the study period. No macroscopic pathologic abnormalities were noted in the animals that died and in the surviving animals of all administration groups examined at the end of the observation period. Under the conditions of this study the median lethal dose of the test item after oral administration was found to be greater than 500 mg/kg and less than 2000 mg/kg body weight in rats.
Acute toxicity dermal:
In an acute dermal toxicity study (Limit Test), young adult Wistar rats (5 males and 5 females) were dermally exposed to a single dose of 2000 mg/kg bw of the undiluted test item 3-[[3-[[(2-cyanoethyl)amino]methyl]-3,5,5- trimethylcyclohexyl]amino]propiononitrile to the clipped application site (dorsal and dorso-lateral parts of the trunk and covered by semi-occlusive dressing during the 24-hour exposure period. The application area comprised at least 10% of the total body surface. The animals were observed for 14 days.
- No mortality occurred
- No signs of systemic toxicity were observed
The following test item-related local skin effects were recorded during the course of the study, local effects occurred within 10 days after application:
- Well-defined erythema (grade 2)
- Incrustations
- Scaling
- All animals gained weight in a normal range throughout the study period.
- No macroscopic pathologic abnormalities were noted in any animal examined at the end of the study (5 males and 5 females).
Accordingly, the acute dermal median lethal dose (LD50) was determined to be LD50, dermal, rat > 2000 mg/kg bw
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 needs to be classified and labelled as harmful after acute oral administration (GHS, cat. 4, H302) under Regulation (EC) No 1272/2008.
