Momentum Grows for Modernizing the US EPA “Six-pack” Battery of Acute Toxicity Tests

January 13, 2016
In the current global regulatory climate favorable for further advancement of in vitro test methods, the US Environmental Protection Agency (US EPA) is driving significant efforts in the United States. The latest endeavor targets the modernization of the battery of acute toxicity tests classically known as the “six-pack” (Fig. 1a). Known for many years as an “all in vivo” testing strategy for products registered under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), the six-pack has recently been revised to include...

Predicting Ocular Irritation of Surfactants Using the Bovine Corneal Opacity and Permeability Assay

January 1, 2014
The Bovine Corneal Opacity and Permeability (BCOP) assay is an ex vivo test used to evaluate ocular irritation. According to the OECD Test Guideline (TG) 437, the BCOP assay can be used to identify chemicals which induce severe/corrosive eye irritation and those that do not require classification. However, BCOP has historically under-predicted certain anionic surfactants, when tested according to the standard liquid protocol. Since neither the basis for selecting the appropriate surfactant test methods, nor the justification for modifications are...
