1 Scope This Standard specifies a method for the iodometric determination of oxyethylene groups in polyethoxylated non-ionic surface active agents. This Standard is applicable to the analysis of polyethoxylated derivatives of primary saturated fatty alcohols, oleyl alcohol, saturated fatty acids, straight and branched chain alkylphenols. It is also applicable in the presence of unreacted alcohols, fatty acids or alkylphenols of the types mentioned above. This Standard is not applicable in the presence of: compounds containing sulfur or nitrogen; compounds containing oxygen or halogen atoms on adjacent carbon atoms other than as oxyethylene groups, for example compounds containing oxypropylene groups; aldehydes or acetals; sterols and derivatives.
