1,4-Dioxane has been widely used as a stabilizer in chlorinated solvents. It has also been used in some industrial processes and for industrial and commercial uses. Recently, concerns about its potential impacts on water quality prompted regulatory actions in New York and investigative research in California.

New York’s new law will limit trace concentrations of 1,4-Dioxane in cosmetics to 10 ppm on December 31, 2022, in personal care and cleaning products to 2 ppm on December 31, 2022, and to 1 ppm at the end of 2023.

As the market leader in low 1,4-Dioxane solutions, BASF is here to help you navigate the evolving regulatory landscape—while delivering the efficiency and performance your customers demand.
