HRIPT Test - Allergy Patch

Allergy patch test is applied to people to understand the cause of allergic skin reactions and to screen certain substances. During this process, patches containing different irritants (allergens) are applied to a person's back and wait 48 hours. At the end of the period, possible sensitive reaction symptoms are examined on the skin.

Companies that produce allergy patches used in these tests must ensure product reliability and make a preliminary risk assessment according to current toxicology standards. The tests applied for this purpose are called HRIPT tests. The abbreviation HRIPT is formed from the initials of the English human repeat insult patch test and stands for human repeat patch test.

In these tests performed in advanced laboratories, product components are separately evaluated in terms of toxicological, physico-chemical data, impurity rate, impurity type, purity level, stability, bibliographic data and quality. In addition, risks are determined by considering the possible exposures of target consumers. These clinical studies are often conducted on human subjects (volunteers) for whom cosmetic and topical products are tested.

In short, the HRIPT test is a widely used test method to determine the irritation, sensitivity and allergic contact potential of allergy patches. In European Union countries, this test method is among the safety tests applied to verify that there is no skin sensitizer (allergen substance) in their formulas.

As new technological products emerge and new cosmetic products are produced, people's allergic reactions to the products they use on the skin gradually increase. These responses can range from simple irritation to more severe discomfort. Manufacturing companies receive many complaints from consumers, large and small, and these complaints naturally create a panic within the company and a series of investigations involving R&D, formulation or marketing teams are initiated. To avoid this, businesses need to produce not only efficient products but also products that will not produce potential allergy responses. In this regard, companies are required to offer consumers products based on reliable evidence, supported by realistic and objective claims. At this point, HRIPT tests are savior.

After performing the HRIPT test in a clinical setting, creams, gels, serums and similar hypoallergenic formulas, ie products with a lower allergy risk, should be offered to consumers. This test is designed to evaluate topical and cosmetic hypoallergenic claims and is an industry-recognized test method accepted by official organizations around the world.
