Administration / exposure

Type of coverage:

occlusive

Vehicle:

unchanged (no vehicle)

Details on dermal exposure:

The test item was applied uniformly over clipped dorsal area of rat skin. Individual rat was applied with a volume of test item, calculated based on the density (0.93237) and latest body weight. Test item was held in contact with the skin with a porous gauze dressing (Approx. 10% of body surface area of rat) and non-irritating tape throughout a 24-hour exposure period. It was ensured that the animals cannot ingest the test item.At the end of the exposure period, residual test item was removed by using distilled water

Interpretation of results:

not classified

Conclusions:

The acute dermal median lethal dose of “Reaction mass of Cardanol diene and Cardanol monoene and Cardanol triene  (CAS No. – 37330-39-5)” was > 2000 mg/kg body weight.

Executive summary:

Acute Dermal Toxicity Study of“ Reaction mass of Cardanol diene and Cardanol monoene and Cardanol triene  (CAS No. – 37330-39-5)”in Wistar Rats This study was performed as per OECD No. 402.

Five male and five female healthy young adult rats were randomly selected and used for conducting acute dermal toxicity study. Ratsfree from injury and irritation of skin were selected for the study. .

At 2000 mg/kg, all the animals were observed normal at 1, 2, 3 and 4 hours post dosing. Animal nos. 1, 4, 7, 8 and 9 were observed with erythema on day 1 and scale formation from day 2 to 8 followed by normal clinical sign till day 14. Animal nos. 5 and 6 were observed with erythema on day 1 and scale formation from day 1 to 6 followed by normal clinical sign till day 14. Animal nos. 2, 3 and 10 were observed with erythema on day 1 and scale formation from day 2 to 7 followed by normal clinical sign till day 14.

The external and internal gross pathological observation of all terminally sacrificed animals did not show any pathological abnormality.

The acute dermal median lethal dose of “ Reaction mass of Cardanol diene and Cardanol monoene and Cardanol triene  (CAS No. – 37330-39-5)”was> 2000 mg/kg body weight.thus based on above results we can conclude that the test substance Cardanol does not exhibit the acute toxcity (Dermal route) as per CLP criteria set by EU.
