Four fractions, isolated by the procedure pre‐sented in a previous paper, are analyzed by gas chromatography to obtain additional information about the formulation. The alkyl homolog distribu‐tion of ethoxylated alcohol nonionic is determined by the gas chromatography (GC) analysis of the re‐sultant alkyl iodides (RI‐FNI) produced by the pre‐viously reported procedure. The relative ratio of alco‐hol sulfate to ethoxylated alcohol sulfate is determined by the GC analysis of the combined acid‐hydrolyzed products of these two active ingredients. The alkyl homolog distributions of the alcohol sul‐fate (AS) and ethoxylated alcohol sulfate are then individually calculated after GC analysis of the resultant alkyl iodides produced from the two in‐gredients by the previous procedure. The source of the original alcohol reactants can often be identified by the characteristic alkyl homologs which are produced by the presented techniques.
