Surface active agents - Gas chromatographic trace determination of free ethylene oxide in ethoxylates

This European Standard specifies a test method for the determination of the content of free ethylene oxide in the range from 1 mg/kg to 100 mg/kg in polyglycols, ethoxylates of alcohols and alkylphenols and in fatty acid polyglycol esters.
