Human Repeated Insult Patch Test

For leading companies in the cosmetic industry, the safety of consumer products and their ingredients is of paramount importance. One of the most effective ways to assess the potential of these products to cause skin sensitization and allergic contact dermatitis (ACD) is the Human Repeated Insult Patch Test (HRIPT).

HRIPT Services

CD Formulation offers HRIPT services as part of its comprehensive safety testing portfolio. The test consists of applying the test material to the volunteer's skin under a closed patch and repeating the application over several weeks. Following this induction period, a rest period is given, followed by a stimulated application to determine if sensitization has occurred. The primary endpoint of the test is the occurrence of a skin reaction, and the test is considered positive if a reaction is observed during the challenge phase.

HRIPT Experimental Procedure

The experimental procedure for HRIPT involves several steps, including subject recruitment, screening, and testing. Volunteers who meet the inclusion criteria are enrolled in the study and their skin is screened for any pre-existing conditions that may interfere with the test results. The test material will be applied to the skin under the occlusive patch for several weeks and repeated at regular intervals. After the induction period, a rest period was given followed by a stimulated application to determine if sensitization had occurred.

Skin reactions are graded according to a standardized scoring system and results are interpreted by a qualified dermatologist or allergist. CD Formulation utilizes state-of-the-art equipment and facilities for HRIPT studies to ensure the accuracy and reproducibility of our results.

Applications of HRIPT

HRIPT is an important tool for evaluating the safety of consumer products and their ingredients. It is particularly useful for evaluating the skin sensitization potential of new chemicals and formulations. HRIPT data can be used to conduct risk assessments and inform regulatory decisions regarding the use of these materials in consumer products.

CD Formulation utilizes HRIPT data as part of our comprehensive safety testing program. Our team of experts uses this data to inform the development of new products and formulations to ensure that they are safe for consumers to use.
