1,4-Dioxane is a synthetic chemical that forms as a by-product during the manufacturing process of certain surfactants and emulsifiers and is miscible in water. It is used primarily as a solvent, and historically as a stabilizer for chlorinated solvents that go into commercial and industrial applications, but a recently signed New York state law prohibits the sale of household cleaning and personal care products containing more than 2ppm 1,4-Dioxane and cosmetics products containing 10ppm 1,4-Dioxane by the end of 2022.
For household cleaning and personal care products the limit will be further reduced to 1ppm at the end of 2023. The state of California is also assessing 1,4-Dioxane in home and personal care products through the Safer Consumer Products program and research is estimated to be completed in three years.
