SAN FRANCISCO–The Environmental Protection Agency (EPA) and L’Oréal announced a research collaboration designed to determine if EPA’s chemical toxicity forecaster (ToxCast)—used to screen chemicals to understand their potential impact on processes in the human body that lead to adverse health effects—can be used in systemic toxicity tests.
“Because of the high costs and length of time it takes for animal testing, not all the chemicals in use have been thoroughly evaluated for potential toxicity," said David Dix, acting director, EPA National Center for Computational Toxicology. “ToxCast is able to rapidly screen thousands of chemicals in hundreds of tests and provide results that are relevant to various types of toxicity."
L’oréal is providing EPA $1.2 million in collaborative research funding plus robust safety data from a set of representative substances from the cosmetic sector, expanding the types of chemical use groups assessed by ToxCast. EPA will compare the ToxCast results to the L’Oréal data to determine if the reliability and the relevance are appropriate for use in the safety assessment of chemicals in cosmetics.
“For more than 30 years, we have invested in Predictive Evaluation for Safety, in other words, animal-free toxicology," said Laurent Attal, executive vice-president, L’oréal Research & Innovation. “Our new L’Oréal Predictive Evaluation Center‘s activity is based on new-generation tests, using reconstructed human tissues, automated platforms, molecular modeling, etc. In this perspective, the ToxCast program from EPA could enrich our testing platforms and help us to predict earlier the safety of substances for our products."
Andrew Rowan, Ph.D., chief scientific officer of The Humane Society of the United States and president and CEO of Humane Society International. “The urgent need for more efficient and relevant methods of safety testing is underscored by the tens of thousands of inadequately assessed chemicals in the environment. A successful outcome of this partnership will go a long way toward demonstrating the value of advanced, non-animal testing tools and the need for ongoing investment in this area."
EPA researchers have published scientific papers showing how ToxCast can be used to predict a chemical’s potential for liver toxicity, developmental toxicity, reproductive toxicity and cancer. ToxCast is screening more than 1,000 chemicals in more than 700 fast, automated tests (called high-throughput screening). ToxCast is supplemented by the Toxicity Testing in the 21st century federal agency research collaboration that uses robotics to test the chemicals.
