Endpoint summary

Description of key information

Acute oral toxicity

The acute oral toxicity in rats was determined according to the method recommended in OECD Guidelines 420 "Fixed dose method" from 1992.

The study was initiated with a sighting study. On the basis of the results of the sighting study, it was decided to carry out main study with dose of 5000 mg /Kg bw with a group of 10 animals.

Eight animals of the main study survived the treatment and showed moderate signs of toxicity

Under the experimental conditions described, the oral LD50 of the test item in rats was found to be >5000 mg/Kg bw

A supporting study where one group of rats (5 males and 5 females) received 1 oral dose of Sandalmysore Core at 5000 mg/Kg bw was also used to assess acute oral toxicity. Macroscopic examination of all animals at the end of the study revealed no test substance related gross abnormalities. Macroscopic examination of one female found dead showed a yellowish intestinal content. Since only 1 animal died, the LD50 value for males and females combined was estimated to exceed 5.0 g/kg bodyweight.

Acute dermal toxicity

The acute dermal toxicity of the substance was assessed according to OECD 402. One group of Wistar rats, comprising 5 males and 5 females, was treated with a single dermal dose of the test item at 2000 mg/kg bodyweight for 24 hours. No mortalities occurred and no signs of systemic toxicity were observed during exposure and the following 14 -day observation period.

The treated skin surface of the animals showed areas with erythema and scales. These lesions disappeared during the second week of observation. Macroscopic examination of all animals at the end of the study revealed no test substance related gross abnormalities. Since no mortalities occurred, the LD50 value for males and females combined was estimated to exceed 2.0 g/body weight.

Justification for classification or non-classification

In the CLP regulation acute toxicity means those adverse effects occurring following oral or dermal administration of a single dose of a substance or a mixture, or multiple doses given within 24 hours, or an inhalation exposure of 4 hours.

The substance does not meet the criteria for classification under the CLP regulations for acute toxicity via the oral route based on the result of an acute oral toxicity study, which gave a LD50 of > 5000 mg/kg bodyweight, which is above the classification cut-off value ( ≤2000 mg/kg bodyweight) for acute oral toxicity.

The substance does not meet the criteria for classification under the CLP regulations for acute toxicity via the dermal route based on the result of a dermal toxicity study, which gave a LD50 of > 2000 mg/kg bodyweight, which is above the classification cut-off value ( ≤2000 mg/kg bodyweight) for acute dermal toxicity.
