IIVS Attends In-Cosmetics Global

April 4, 2017
IIVS President, Erin Hill, and Study Director, Tinashe Ruwona are attending the In-Cosmetics Global meeting, April 4-6, in London.  Dr. Ruwona, who leads our skin sensitization screening program, presented during the Skin Toxicology Workshop. His presentation,  "Integrated Testing Strategies for Assessing the Skin Sensitization Potential of Cosmetics",  Dr. Ruwona explores the various test methods and how best to combine them to ensure consumer safety.  Read more....

Addressing the Assignment of US EPA Hazard Categories for Dermal Safety by a Revised Prediction Model of the Validated In Vitro Skin Irritation Test (OECD TG 439)

March 30, 2017
One of the current goals of the United States Environmental Protection Agency Office of Pesticide Programs (US EPA OPP) is to replace by non-animal testing methods as many of the endpoints of the battery of acute toxicity tests known as the “6-pack” as possible. One of the “6-pack” tests is the Draize rabbit test for dermal irritation. We investigated whether the validated in vitro Skin Irritation Test (SIT, OECD TG 439) can be used to determine US EPA OPP dermal...

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, 2017
The 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...

The 3T3 Neutral Red Uptake Phototoxicity Test Training Video – Chinese

November 21, 2016
This new training video explores a cell-based method for assessing Phototoxicity – or the potential for chemicals to cause damage after being exposed to light. The method is used widely around the world by many industries, including the cosmetics and pharmaceutical sectors. Disclaimer: Please note that the procedures shown in this video were for demonstration purposes only and that all assay procedures, except the UVA/dark exposure, should be performed in a biological safety cabinet using aseptic techniques. Due to video production...

Webinar: How GLPs Enhance the Quality of Regulated and Non-Regulated Toxicology

October 18, 2016
This 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...

Advancing Non-animal Testing Methods: First Set of Novel Knowledge Tools Published

October 18, 2016
An adverse outcome pathway, or AOP, is a highly structured way of describing a toxicological process which can lead to an adverse health effect in humans or wildlife, caused by an unsafe exposure to a chemical substance. The first five adverse outcome pathways have now been published by experts. The AOPs are novel knowledge management tools in toxicology and are useful for supporting risk assessment to human health. They are also valuable for helping to avoid animal testing through the...

IIVS Announces Suite of Non-Animal Methods to Reduce Animal Testing for Skin Sensitization

September 6, 2016
GAITHERSBURG, MD – September 6, 2016 – In response to a newly published OECD Test Guideline, IIVS announces the addition of the Human Cell Line Activation Test (h-CLAT, OECD TG 442E) to its suite of non-animal assays to determine skin sensitization. The assessment of skin sensitization has historically involved the use of laboratory animals; specifically guinea pigs and mice. In recent years, international research and validation efforts have paved the way for the use of non-animal methods. “Industry has provided the field...

KeratinoSens (OECD 442D)

August 24, 2016
The KeratinoSensTM assay is a cell-based reporter gene assay that models the second key event in the Adverse Outcome Pathway for Dermal Sensitization, namely keratinocyte activation.  This approach measures the induction of luciferase under the control of the antioxidant response element (ARE) derived from the human AKR1C2 gene, and can be used in a Weight of Evidence approach as an alternative to animal testing methods for the purpose of hazard identification. IIVS has participated in validation studies led by the assay developer...

Short Time Exposure (STE, OECD 491)

August 24, 2016
The Short Time Exposure (STE) assay, developed by Kao Corporation (Japan), is an in vitro assay used to assess acute eye irritation potential as an alternative to the traditional in vivo Draize test.  The test method evaluates the cytotoxicity induced by a series of test chemical dilutions in a monolayer of rabbit corneal fibroblasts (Statens Seruminstitut Rabbit Cornea – SIRC) after a single five-minute exposure. Two prediction models were initially developed for the STE assay — one categorizes the test material as...
