    Significance and Use

    5.1 Moisture analysis (along with purity) is used to calculate the amount of active polymer in the material and must be considered when determining the amount of sodium carboxymethylcellulose to use in various formulations.

    1. Scope

    1.1 These test methods cover the testing of sodium carboxymethylcellulose.

    1.2 The test procedures appear in the following order:




    4 – 9

    Degree of Etherification:


     Test Method A—Acid Wash

    10 – 17

     Test Method B—Nonaqueous Titration

    10, 12, 18 – 23


    24 – 29


    30 – 37

    Sodium Glycolate

    38 – 46

    Sodium Chloride

    47 – 54


    55 – 61
