Executive summary:

The acute dermal toxicity of Sodium p-cumenesulphonate was assessed following official method OECD 402, Acute dermal Toxicity. The test item elicited moderate primary irritation on the test sites. The test results are considered applicable for potassium p-cumenesulphonate based on the chemical similarity.
