Description of key information

Acute oral toxicity: 

The acute oral toxicity dose (LD50) was considered based on study conducted for the test chemical. The LD50 value is >2000 mg/kg bw, for acute oral toxicity. Thus, comparing this value with the criteria of CLP regulation, the given test chemical cannot be classified for acute oral toxicity.

Acute Inhalation Toxicity:

The acute inhalation toxicity study need not be conducted because exposure to humans via inhalation route is not likely taking into account due to the low vapour pressure of the test chemical, which is reported to be 0.000750 mm Hg. Thus, exposure to inhalable dust, mist and vapour of the chemical is highly unlikely. Therefore this study is considered for waiver.

Acute Dermal toxicity:

The acute dermal toxicity dose (LD50) was considered based on study conducted on rats for the test chemical. The studies concluded that the LD50 value is >2000 mg/kg bw, for acute dermal toxicity. Thus, comparing this value with the criteria of CLP regulation, the given test chemical cannot be classified for acute dermal toxicity.

Interpretation of results:

Conclusions:
Acute Oral Toxicity of test chemical was studied in Rats, This study was performed as per OECD No. 423.
Under the condition of the study,Acute oral LD50 of test chemical was determined to be >2000 mg/kg body weight
Executive summary:

Acute Oral Toxicity of test chemical was studied in Rats, This study was performed as per OECD No. 423.

Six female Wistar rats were selected for acute oral toxicity study. The animals were fasted for minimum 16-18 hours prior to dosing and for 4 hours post dosing, with food withheld but drinking water provided ad libitum. The time intervals between dosing were determined by the onset, duration and severity of toxic signs.

Three rats of first group were dosed with starting dose of 2000 mg/kg body weight and the animals did not show any mortality so another three animals of the same group were dosed with 2000 mg/kg body weight and one mortality was observed on day 1 post dosing. Hence, further dosing was stopped.

Body weights of surviving animals were recorded on day 0 (prior to dosing) 7 and 14. The animal was weighed immediately after found dead. Mean Body weight of all surviving animals treated with 2000 mg/kg body weight was observed with gain on day 7 and 14, as compared to day 0

Under the conditions of this; the LD50 value of test chemical in female rats was >2000 mg/kg body weight.

8.2 Preparation of Application Site
Approximately 24 h prior to treatment, the fur of dorsal area of the trunk (approximately 10% body surface area) of rats was clipped by using clipper.
8.3 Test Item Application Procedure
The test item was applied uniformly over clipped dorsal area of rat skin. Individual rat was applied with an amount of test item, calculated based on the density (1.0898) and latest body weight. Test item was held in contact with the skin with a porous gauze dressing (Approx. 10% of body surface area of rat) and non-irritating tape throughout a 24-hour exposure period. It was ensured that the animals cannot ingest the test item. At the end of the exposure period, residual test item was removed by using distilled water. The animals were dosed between 11:19 to 11:32 a.m.

Interpretation of results:
other: Not classified
Conclusions:
Under the conditions of study in acute dermal toxicity study,the acute dermal median lethal dose of test chemical was determined to be >2000 mg/kg bw when tested in rats.
Executive summary:

Acute Dermal Toxicity was studied for test chemical in Wistar Rats,This study was performed as per OECD No.402.

Five male and five female healthy young adult rats were randomly selected and used for conducting acute dermal toxicity study. Rats free from injury and irritation of skin were selected for the study. Approximately twenty four hours prior to dermal application of test item, approximately 10% of body surface area of each rat was clipped. A limit dose of 2000 mg/ kg body weight of test item based on the density (1.0898) and latest body weight was applied by single dermal application and observed for 14 days after treatment.

On test day 0, calculated amount of test item was applied directly on the intact skin of clipped area of rats; the porous gauze dressing was put on to the intact skin of clipped area. This porous gauze dressing was covered with a non-irritating tape. After the 24-hour application period, the dressings were removed and the skin was gently wiped with distilled water. The skin reactions were assessed.

Under the conditions of this; acute dermal toxicity study of test chemical in rats is as given below: The acute dermal median lethal dose of test chemical was  > 2000 mg/kg body weight. and the substance is not classified as per the CLP regulation.

Additional information

Acute oral toxicity:

Acute Oral Toxicity of test chemical was studied in Rats, This study was performed as per OECD No. 423.

Six female Wistar rats were selected for acute oral toxicity study. The animals were fasted for minimum 16-18 hours prior to dosing and for 4 hours post dosing, with food withheld but drinking water provided ad libitum. The time intervals between dosing were determined by the onset, duration and severity of toxic signs.

Three rats of first group were dosed with starting dose of 2000 mg/kg body weight and the animals did not show any mortality so another three animals of the same group were dosed with 2000 mg/kg body weight and one mortality was observed on day 1 post dosing. Hence, further dosing was stopped.

Body weights of surviving animals were recorded on day 0 (prior to dosing) 7 and 14. The animal was weighed immediately after found dead. Mean Body weight of all surviving animals treated with 2000 mg/kg body weight was observed with gain on day 7 and 14, as compared to day 0

Under the conditions of this; the LD50 value of test chemical in female rats was >2000 mg/kg body weight.

Acute inhalation toxicity:

The acute inhalation toxicity study need not be conducted because exposure to humans via inhalation route is not likely taking into account due to the low vapour pressure of the test chemical, which is reported to be 0.000750 mmHg. Thus, exposure to inhalable dust, mist and vapour of the chemical is highly unlikely. Therefore this study is considered for waiver.

Acute dermal toxicity:

Acute Dermal Toxicity was studied for test chemical in Wistar Rats,This study was performed as per OECD No.402.

Five male and five female healthy young adult rats were randomly selected and used for conducting acute dermal toxicity study. Rats free from injury and irritation of skin were selected for the study. Approximately twenty four hours prior to dermal application of test item, approximately 10% of body surface area of each rat was clipped. A limit dose of 2000 mg/ kg body weight of test item based on the density (1.0898) and latest body weight was applied by single dermal application and observed for 14 days after treatment.

On test day 0, calculated amount of test item was applied directly on the intact skin of clipped area of rats; the porous gauze dressing was put on to the intact skin of clipped area. This porous gauze dressing was covered with a non-irritating tape. After the 24-hour application period, the dressings were removed and the skin was gently wiped with distilled water. The skin reactions were assessed.

Under the conditions of this; acute dermal toxicity study of test chemical in rats is as given below: The acute dermal median lethal dose of test chemical was  > 2000 mg/kg body weight. and the substance is not classified as per the CLP regulation.

Justification for classification or non-classification

Based on the above studies on test chemical, it can be concluded that LD50 value is >2000 mg/kg bw, for acute oral and acute dermal toxicity. Thus, comparing this value with the criteria of CLP regulation, the given test chemical cannot be classified for acute oral and acute dermal toxicity. For acute inhalation toxicity wavier was added so, not possible to classify.
