简要总结
Several types of test methods are used widely for the evaluation of safety of cosmetics in human, which include single patch test, in-use test, 7/14/24 Days cumulative irritation patch testing, human repeated insult patch test (HRIPT) for irritation and sensitization potential.
Primary Irritation Patch Test is performed to evaluate the primary skin irritation that can range from none, mild, moderate to severe irritation. This results from reversible inflammatory changes in the skin following the application of a test substance depending on the irritation potential of the product. Based on the severity of irritation caused due to the interaction of ingredients or composition of the test substance with the skin can cause perceivable sensations or symptoms. On the basis of this, the possible hazards likely to arise from exposure of the skin to the test substance can be assessed. To know the safety or possible irritant potential of these products, it should be tested in small group of humans before release of the product in market. This allows to measure and evaluate the probable inflammatory response to an irritant which occurs only at the site of exposure. The response tends to be universal (produces a reaction in most individuals) and depends on the strength and duration of exposure.
The Test Products to be tested can involve Rinse-off products, Leave-on products for skin, Volatile substances, Talc products, Wipes etc. Along with this, different types of patches can be used for cosmeceuticals, pharmaceutical, herbal cream/lotions as well as herbal Transdermal/Topical patches can also be tested by using a similar outline
To determine the potential of the test articles to cause cutaneous irritation in adult human subjects after single 24-hour occluded patch application.
