The gold standard Human Repeat Insult Patch Test expertise -HRIPT- available worldwide with Zurko Research

Prior to launching any new product on the market, it’s important to evaluate its safety, especially for those products that will come into direct contact with the skin. The Human Repeat Insult Patch Test (HRIPT or RIPT test) is considered the gold standard for in vivo safety assessment, ensuring that tested products do not cause skin irritation or induce skin sensitivity. Additionally, conducting an HRIPT study allows to evaluate the potential allergenicity of tested product and is a crucial safety study to support the hypoallergenic claim.

For those in the cosmetics or personal care product industry, conducting safety evaluations through clinical testing, such as HRIPT, becomes an essential aspect of both product development and regulatory compliance.

Zurko Research HRIPT-RIPT testing capabilities

At Zurko Research, our commitment to our clients and their consumers is steadfast. Through a wide range of safety clinical studies, including HRIPT, we strive to identify any potential irritation or sensitization issues, thus minimizing the risk of adverse reactions for consumers and ensuring the success of our clients.

Our protocol consists of three different phases, ensuring a comprehensive evaluation of products that come into direct contact with the skin.

• Three-phase application:Our HRIPT studies adhere to a standardized and meticulously structured three-phase application process, encompassing Induction, Rest, and Challenge phases.

This approach is substantiated by research, including contributions from Marzulli F. and Maibach.
