Endpoint summary
Administrative data
Description of key information
Skin Irritation:
Negative effects were observed in all the rabbits after 72 hours of observation. The mean irritation score was 0.0 after 72 hours. Hence, Sodium 4-chloro-3-nitrobenzenesulphonate can be considered to be not irritating to skin.
Eye Irritation:
No special observations were observed in rabbits after 7 days. The mean irritation score for cornea, conjunctivae (redness and swelling) and iris after 7 days were 0,0,0 respectively.
Based on the scores and observations, Sodium 4-chloro-3-nitrobenzenesulphonate can be considered to be not irritating to rabbit eyes.

- Executive summary:
The objective of the study was to determine the cutaneous toxicity of Sodium 4-chloro-3-nitrobenzenesulphonate.

For the determination of the acute irritative effect, the dorsal and lateral parts of the trunk were shaved 16-24 hours prior to treatment with an electric cutting machine. The test substance was administered as an 83% aqueous solution. In addition, 500 mg of the substance were dissolved with 0.1 ml of double-distilled water. The aqueous solution was spread on a flax of about 6 cm 2 on the gastric dorsal skin, covered with a 2.5 × 2.5 cm gauze swab Transfilmine Combined Fixiarl for four hours.During the exposure time, the rabbits were housed individually in separate cages. After the end of the exposure time, the bare skin areas were rinsed with water and soap and dried. The observation period lasted 72 hours or 7 days. Each animal was observed at 1h, 24, 48, 72 hours and, if necessary, 7 days after treatment for erythema and edema. Skin lesions were scored according to the following OECD Guidelines on testing materials where appropriate responses were recorded.
Negative effects were observed in all the rabbits after 72 hours of observation. The mean irritation score was 0.0 after 72 hours. Hence, Sodium 4-chloro-3-nitrobenzenesulphonate can be considered to be not irritating to skin.
