Science Wednesday: EPA Teams Up with L’Oréal to Advance Research

Each week we write about the science behind environmental protection. Previous Science Wednesdays.

By Monica Linnenbrink

Now I can look great and feel good about using my favorite mascara. Why? Because EPA researchers are collaborating with L’Oréal to help end the need for animal testing. EPA is using its ToxCast program to screen chemicals to understand their potential impact on biological processes that may lead to adverse health effects.

EPA’s ToxCast program screens chemicals using state-of-the-art scientific methods (including robots!) to learn how these chemicals affect the human body. We’ve never tested chemicals found in cosmetics before, so this partnership with L’Oréal will expand the types of chemicals that ToxCast screens.

L’Oréal is providing EPA $1.2 million in collaborative research funding plus safety data from a set of representative substances used in cosmetics, which will expand the types of chemical use groups assessed by ToxCast. EPA will then compare its ToxCast results to L’Oréal’s data to determine if ToxCast is appropriate for use in assessing the safety of chemicals used in cosmetics.

Traditional chemical toxicity testing is very expensive and time consuming, so many chemicals in use today have not been thoroughly evaluated for potential toxicity. ToxCast, on the other hand, is able to rapidly screen thousands of chemicals via hundreds of tests and provide results that are relevant to various types of toxicity.

As someone who uses L’Oréal products, I’m excited that they are taking the initiative to better understand how chemicals in their cosmetics might interact with my body’s natural processes. I’m also excited to hear that they are exploring new ways of testing that could end the need for animal testing. Since I use their products on my face, it’s nice to know that L’Oréal is working to ensure their products are safe to use and are working to do this in an animal friendly way.
