Surface active agents. Determination of 1,4-dioxan residues in surfactants obtained from epoxyethane by gas chromatography1 Scope This International Standard provides a method for the determination of 1,4 dioxane residues in surfactants which are synthesized from epoxyethane, such as alkyl ether sulfates and alcohol ethoxylates. The method is applicable for samples containing 1,4 dioxane more than 5 mg kg. For samples containing 1,4 dioxane more than 100 mg kg, the sample solutions should be diluted to appropriate concentration.
