Description of key information

Acute oral toxicity: 

The acute oral toxicity dose (LD50) was considered based on different studies conducted on rats and mice for the test chemical. The 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.

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 6.61E-009 Pa. 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 rabbits for the test chemical. 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.

Executive summary:

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 and mice for test chemical. The studies are summarized as below –

1. The acute oral toxicity study was conducted by using test chemical in mice at the concentration of 2400 mg/kg bw. 50% mortality was observed at 2400 mg/kg bw. Hence, LD50 value was considered to be 2400 mg/kg bw, when mice were treated with given test chemical via oral route.

2. The acute oral toxicity study was conducted by using test chemical in rats at the concentration of 5000 mg/kg bw. No mortality was observed at 5000 mg/kg bw. Hence, LD50 value was considered to be >5000 mg/kg bw, when rats were treated with given test chemical via oral route.

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.

2. The acute oral toxicity study was conducted by using test chemical in rats at the concentration of 5000 mg/kg bw. No mortality was observed at 5000 mg/kg bw. Hence, LD50 value was considered to be >5000 mg/kg bw, when rats were treated with given test chemical via oral route.

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.

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.
