In Vitro Assessment of Skin Irritation Potential of Surfactant-based Formulations by Using a 3-D Skin Reconstructed Tissue Model and Cytokine Response
January 24, 2017The personal care industry is focused on developing safe, more efficacious, and increasingly milder products, that are routinely undergoing preclinical and clinical testing before becoming available for consumer use on skin. In vitro systems based on skin reconstructed equivalents are now established for the preclinical assessment of product irritation potential and as alternative testing methods to the classic Draize rabbit skin irritation test. We have used the 3-D EpiDerm™ model system to evaluate tissue viability and primary cytokine interleukin-1α release...
Webinar: How GLPs Enhance the Quality of Regulated and Non-Regulated Toxicology
October 18, 2016This one-hour webinar, led by IIVS Director of Quality and Compliance, introduces some of the concepts of Good Laboratory Practices (GLPs) designed to promote study and data integrity within an in vitro toxicology framework. Applying these concepts within your own laboratory should aid in production of robust, repeatable studies. View Slides...
Skin Corrosion Test (OECD 431)
September 1, 2016Skin Corrosion in the regulatory hazard classification and labeling context is defined as the production of irreversible damage to skin, generally evident as necrosis through the epidermis and into the dermis, following a defined chemical exposure. The In Vitro Skin Corrosion Test is an in vitro, non-animal test designed to identify those chemicals and mixtures capable of inducing skin corrosion (UN GHS Category 11), and in some cases to partially subcategorize corrosives into UN GHS Sub-Categories 1A or 1B and...
Dermal Irritation Time to Toxicity
August 24, 2016Product development/product stewardship scientists and formulators typically find it desirable to compare or rank order the skin irritation potential of candidate formulations, or to monitor the impact of changes in formulations or ingredients on skin tolerance. Foremost, industry researchers need timely, accurate, cost-effective test results to help them get safer products to the marketplace. The Dermal Irritation Screening assay using a Time-to-Toxicity (ET50) protocol coupled with IIVS’ expertise in the methods help researchers meet their testing goals. The assay is designed...
