- Conclusions:
- The substance 1,3-Phenylenediamine-4-sulfonic acid was considered to be moderately irritant to rabbit skin.
- Executive summary:
Skin irritation test was conducted to evaluate the irritation potential of 1,3-Phenylenediamine-4-sulfonic acid.
500 mg of test substance was administered on to the skin of rabbit. Moderate irritation effects were observed. Therefore, the substance 1,3-Phenylenediamine-4-sulfonic acid was considered to be moderately irritant to rabbit skin.
