Cosmetics & Personal Care
August 24, 2016European legislation and US research activities towards ‘21st century toxicology’ are setting the standards for animal-free toxicological assessments and the cosmetics industry has been the first to feel the effects. As per EU Regulation 1223/2009, animal testing of cosmetic ingredients and finished products is currently banned in the EU, as is the marketing of finished cosmetic products and the ingredients contained therein which were tested on animals for cosmetic safety assessment purposes. These bans hold irrespective of the availability of validated...
Corrositex (OECD 435)
August 23, 2016The Corrositex® assay is a standardized and quantitative in vitro test developed as a replacement for the dermal corrosivity rabbit test. The Corrositex kit, manufactured by In Vitro International (IVI), uses a proprietary biobarrier membrane to model the skin for evaluating the potential dermal corrosivity of a test material. A test material is evaluated based on its penetration through the biobarrier membrane into a Chemical Detection System (CDS). The time required for the test material to break through the biobarrier and into the CDS is...
Pharmaceutical
August 16, 2016Pharmaceutical companies can use in vitro testing for assessing worker safety. Pharmaceutical intermediates should be evaluated to determine the primary hazards associated with them so that those involved in the manufacturing process can take necessary precautions to avoid hazardous exposures. Pharmaceutical compounds can vary widely in their physical forms, such as powders, liquids, and creams. Many in vitro assays such as those using 3-dimensional tissue constructs, and the Bovine Corneal Opacity and Permeability (BCOP) Assay, are suitable for testing different test...
Occupational Safety & Industrial Hygiene
July 28, 2016Employers are required to inform workers of the hazards of the chemicals or products that they are using. Many in vitro assays are suited to accomplish this goal. As Hazard Communication is now aligned with the Globally Harmonized System (GHS), assays that are approved for assigning GHS hazard categories can provide a method for properly labelling chemicals and preparing safety data sheets. Skin Corrosion assays (Reconstructed Human Epidermis (OECD TG 431) and Membrane Barrier Test (OECD TG 435)) can be used...
Evaluation of the Validated In Vitro Skin Irritation Test (OECD TG 439) for the Assignment of EPA Hazard Categories
April 1, 2016Progress within the in vitro toxicology field has made available testing platforms based on reconstructed tissue models that are validated to address the skin corrosion and irritation endpoints. While the validated in vitro assays can be used for the hazard identification of chemicals irritant to skin in accordance with the United Nations (UN) Globally Harmonized System (GHS) for Classification and Labeling of Chemicals, they were not calibrated to address the classification system used by the United States Environmental Protection Agency...
Momentum Grows for Modernizing the US EPA “Six-pack” Battery of Acute Toxicity Tests
January 13, 2016In 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...
