Advinus has broadened its scope of services through the introduction of in vitro Skin Irritation (OECD 439) and in vitro skin Corrosion tests (OECD 431). These in vitro tests will be assessed using the Human 3-Dimensional EpiSkin®test kit. The tests have been validated in our laboratory by employing the OECD Guideline mandated proficiency substances. The in vitro EpiSkin® tests are routinely used for cosmetic raw materials and cosmetic formulations. In addition, current OECD guidelines for in vivo (whole animal) skin irritation tests mandate that prior to testing in animals all agrochemical and industrial (REACH) chemicals must be evaluated by employing in vitro tests. These tests are offered both under GLP for regulatory submission and also under non-GLP for screening in the research mode. Both in vitro EpiSkin® tests can be taken up in one week following supply of the compound and results can be provided with a week.
