Description of key information

An acute toxicity study via the oral route was not carried out as the substance is classified as corrosive. However, oral LD50 values for rat ranging from 400 mg/kg bw to 1000 mg/kg bw were reported in a handbook. Based on these values the subtance should be classified as acute toxicity Category 4 in accordance with Regulation (EC) No 1272/2008.

There was no available data on the acute toxicity of the substance via the inhalation route.

For acute toxicity via the dermal route, values of dermal LD50 of 200 -400 mg/kg bw for rabbit was reported in a toxicology handbook. Based on the reported values the substance meets the criteria for Acute toxicity Category 3 via the dermal route in accordance with CLP regulation.

Interpretation of results:
Category 4 based on GHS criteria
Conclusions:
LD50 values for rats of 400 mg/kg and 1000 mg/kg bw were reported in a toxicology handbook. Both values fall within the classification criteria for Acute Toxicity Category 4 via the oral route in accordance with Regulation (EC) N° 1272/2008.
Executive summary:

Two oral LD50 values for rat from seperate unpublished studies were reported in a scientific handbook. No information on the method was given. The LD50 values of 400 mg/kg bw and 1000 mg/kg bw both fall within the classification criteria for Acute Toxicity Category 4 via the oral route in accordance with Regulation (EC) N° 1272/2008.

Additional information

Justification for classification or non-classification

An acute oral LD 50 of 400 mg/kg in rats was reported in a toxicology handbook. According to CLP Regulation an Acute LD 50 value between 300 and 2000 mg/kg meets the criteria for classification as Acute Toxicity Category 4 via the Oral route.

An acute dermal LD 50 of 200-400 mg/l was reported in a toxicology handbook. According to CLP Regulation an Acute LD 50 value between 200 and 1000 mg/kg meets the criteria for classification as Acute Toxicity Category 3 via the dermal route.
