    These test methods cover the sampling and chemical analysis of paste, powder, or liquid detergent alkylbenzene sulfonates. Reagent grade chemicals shall be used in all tests. The distillation method shall be preferred for moisture testing. Water by the Karl Fischer titration method shall be used when the amount of moisture is low. Total matter insoluble in alcohol, neutral oil content, chlorides calculated as sodium chloride, and pH shall also be tested.

    Preparation of Sample




     Distillation Method

    11 – 14

     Karl Fischer Method

    15 – 20

    Total Matter Insoluble in Alcohol

    21 – 23

    Neutral Oil

    24 – 27

    Chlorides Calculated as Sodium Chloride (NaCl)

    28 – 31



    1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
