On June 28, 2019, the California Department of Toxic Substances Control (DTSC) will host the first public workshop on 1,4-Dioxane in Personal Care and Cleaning Products. 1,4-Dioxane, a solvent and stabilizer for chlorinated solvents, which is produced from both petroleum sources and from biobased ethylene oxide, has been identified by DTSC as a likely human carcinogen and an emerging contaminant found in beauty, personal care, hygiene, and cleaning products. DTSC is requesting additional information from stakeholders about potential adverse impacts from 1,4-dioxane in consumer products; its presence in personal care and cleaning products; and the feasibility of removing it from these products. To view the background document and submit comments, please visit DTSC’s CalSAFER portal. The comment period closes on August 21, 2019.
