The silicones industry is committed to the responsible use of silicones and international environmental stewardship. The industry continues to evaluate the science behind its materials, and monitor the presence of substances in the environment through robust environmental monitoring programs.
To provide the U.S. Environmental Protection Agency (EPA) with environmental monitoring data on one of the basic substances used to make silicones, the siloxane D4, in March 2016 members of the SEHSC began an environmental monitoring program, designed in partnership with EPA, to assess levels of D4 in the environment. In September 2017, members of SEHSC submitted the final results of its D4 environmental monitoring program to EPA. An independent peer-reviewed study of the monitoring program concluded that D4 does not harm the environment and that no further regulatory restrictions are warranted.
