Description of key information
Acute oral toxicity:
The acute oral toxicity dose (LD50) was considered based on different studies conducted on rats for the test chemical. The studies concluded that 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 very low vapour pressure of the test chemical. 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 different studies conducted on rats for the test chemical. The studies concluded that 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.

In different studies, the given test chemical has been investigated for acute oral toxicity to a greater or lesser extent. Often are the studies based on in-vivo experiments in rodents, i.e. most commonly in rats for test chemical. The studies are summarized as below –
The reported study was mentioned in peer-reviewed journal and conducted to determine acute oral toxicity dose by using the given test chemical in adult Wistar rat at the dose concentration of 2000 mg/kg bw orally. Animals were observed for mortality. No mortality was observed at 2000 mg/kg bw. Hence, the Lethal concentration value (LD50) was considered to be >2000 mg/kg bw, when adult Wistar rat was treated with the given test chemical orally.
The above study is supported with another study mentioned in handbook and authoritative database for the given test chemical. The acute oral toxicity study was performed in rat at the dose concentration of 2000 mg/kg bw. Animals were observed for mortality. No mortality was observed at 2000 mg/kg bw. Hence, the Lethal concentration value (LD50) was considered to be >2000 mg/kg bw, when rat was treated with the given test chemical orally.
Both the above studies are further supported with the data available in handbook and authoritative database using the given test chemical in rat at the dose concentration of 2000 mg/kg bw. The animals were observed for mortality. No mortality was observed at 2000 mg/kg bw in treated animals. Hence, the Lethal concentration value (LD50) was considered to be >2000 mg/kg bw, when rat was treated with the given test chemical orally.
Thus, based on the above summarised studies on test chemical, it can be concluded that LD50 value is >2000 mg/kg bw. Thus, comparing this value with the criteria of CLP regulation, the given test chemical cannot be classified for acute oral toxicity.

The reported study was mentioned in study report and conducted to determine acute dermal toxicity dose by using the given test chemical as per OECD Guideline 402 (Acute Dermal Toxicity) in Sprague Dawley rats.
The test item was applied to shorn skin of 5 male and 5 female animals at 2000 mg/kg body weight. Administration of the test item at 2000 mg/kg did not result in any skin reaction at the site of application during the study period of 14 days. Administration of the test item did not result in any signs of toxicity and mortality during the study period of 14 days. Animals exhibited normal body weight gain through the study period of 14 days. Gross pathological examination did not reveal any abnormalities attributable to the treatment.
Hence, the acute dermal LD50 value was considered to be >2000 mg/kg bw, when male and female Sprague Dawley rats were semiocclusively treated with test chemical by dermal application following 14 days of observation period according to OECD Guideline 402 (Acute Dermal Toxicity).
The above study is supported with the study mentioned in authoritative database and conducted to determine acute dermal toxicity dose of the given test chemical in rats at the concentration of 3000 mg/kg bw. No mortality was observed in treated rats at 3000 mg/kg bw. Therefore, LD50 was considered to be >3000 mg/kg bw, when rats were treated with test chemical by dermal application.
Thus, based on the above summarised studies on test chemical, it can be concluded that LD50 value is >2000 mg/kg bw. Thus, comparing this value with the criteria of CLP regulation, the given test chemical cannot be classified for acute dermal toxicity.

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.
