简要总结
Skin Irritation Test:
Irritants are substances that damage the skin. The damage will depend upon the nature, concentration and duration of exposure. Irritation is manifested as inflammatory responses such as erythema (redness), Oedema (swelling), and vesiculation and finally to an intense suppurate reaction without the involvement of the immune system. The irritation potential of a substance can be assessed by human patch test.
