  • METHODS FOR MITIGATING 1,4-DIOXANE AND 1,4-DIOXANE PRECURSORS IN SURFACTANT SOLUTIONS
    Publication number: 20250043187
    Abstract: A method of mitigating the formation of 1,4-dioxane and precursors of 1,4-dioxane in alkyl ether sulfate surfactants is disclosed. The method involves adding one or more alcohol, hydrotrope or anti-oxidant additives to an aqueous solution of alkyl ether sulfate surfactant having at least two ethylene oxide groups. The alcohol, hydrotrope, or anti-oxidant is added to the alkyl ether sulfate solution in an amount effective to reduce the formation of diethylene glycol monosulfate, a precursor of 1,4-dioxane, and also reduce the formation of 1,4-dioxane.
