Description of key information
Oral Toxicity
The test substance was assessed in healthy random bred rats of the Tif RAif (SPF) strain. The animals were tested for acute oral toxicity. Animals were fasted overnight and treated by oral intubation. Physical condition and rate of deaths were monitored throughout the whole observation period. Within 2 hours after treatment the rats in all dosage groups showed sedation, dyspnoea, exophthalmus, curved position and ruffled fur. Additionally in the highest dosage group convulsions and trismus were also observed. The surviving animals recovered within 7 to 12 days. The acute oral LD50 of the test material in rats of both sexes observed over a period of 14 days was demonstrated to be 3398 (2812-4108) mg/kg bw.
Dermal Toxicity
The acute dermal toxicity in rats of both sexes was assessed. Healthy random bred rats of the Tif: RAif (SPF) strain were prepared for testing approximately 24 hours before treatment by shaving an area on the back of the rats of approximately 60 square cm with an electric clipper. The test material was evenly dispersed on the skin with a syringe and was covered with an occlusive dressing which was fastened around the trunk with an adhesive elastic bandage. After 24 hours the dressing was removed, the skin was cleaned with lukewarm water and the reaction of the skin was appraised. No symptoms and no local skin irritation were seen. No mortalities occurred; no substance related gross organ changes were seen. The acute dermal LD50 of the test material in rats of both sexes observed over a period of 14 days is greater than 3170 mg/kg bw.
Inhalation Toxicity
In accordance with column 2 of REACH (Regulation (EC) No 1907/2006) Annex VIII, the acute toxicity by inhalation study (required in section 8.5.2) does not need to be conducted as acute toxicity studies are available for the oral and dermal routes of exposure. Furthermore, the substance is marketed as a
component of a product which is made of a vicous liquid, which is not inhalable
