These test methods cover the chemical analysis of sulfonated and sulfated oils. Water by distillation with volatile solvent and moisture and volatile matter by hot-plate shall be tested to meet the requirements prescribed. Titration test, extraction-titration test, and ash-gravimetric test shall be performed to meet the requirements specified. Total desulfated fatty matter, total active ingredients, unsaponifiable non-volatile matter, inorganic salts, total alkalinity, and total ammonia shall be tested to meet the requirements prescribed. In the absence of ammonium or triethanolamine soaps test method, brine test method, and in the presence of ammonium or triethanolamine soaps test method shall be performed to meet the requirements prescribed. Water-immiscible organic solvents volatile with steam shall be tested to meet the requirements prescribed.
