Conclusions:

The acute oral LD50 (Cut-off value) of Reaction mass of Cardanol diene and Cardanol monoene and Cardanol triene (CAS No. – 37330-39-5) was 5000 mg/kg body weight.

Executive summary:

Acute Oral Toxicity was studied of Reaction mass of Cardanol diene and Cardanol monoene and Cardanol triene  (CAS No. – 37330-39-5) in Rats.

Three rats of the first group G1 were dosed with starting dose of 300 mg/kg body weight and the animals did not show any mortality. So another three animals of the same group G1 were dosed with 300 mg/kg body weight and no mortality was observed. Next, three animals of group G2 were dosed with 2000 mg/kg body weight and no mortality was observed.

Under the conditions of this; and based on the examinations performed, acute oral toxicity study of Reaction mass of Cardanol diene and Cardanol monoene and Cardanol triene  (CAS No. – 37330-39-5)in female rats is as given below:

The acute oral LD₅₀(Cut-off value) of Cardanol (CAS No. – 37330-39-5) was 5000 mg/kgbody weight.
