Strategies for Eye Irritation Testing
September 17, 2018Determination of ocular irritation potential is a key toxicological endpoint required to support chemical and raw material characterization and industrial hygiene, to guide product development, and to achieve final product safety standards. IIVS possesses extensive experience with numerous test methods and testing strategies for commercial, industrial and regulatory applications. From standard regulatory hazard assessments to providing information on the degree of ocular irritation, to discriminating among extremely mild eye area products, IIVS’ Study Directors take the time to understand your...
Short Time Exposure (STE, OECD 491)
August 24, 2016The 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...
