Standard Test Methods for Hydroxypropylcellulose

Fecha:
2016-12-27 /Active
Significance and Use:

5.1 The results of this test are used for calculating the total solids in the sample; and, by common usage, all materials volatile at this test temperature are designated as moisture.

5.2 Moisture analysis (along with residue on ignition) is a measure of the amount of active polymer in the material and must be considered when determining the amount of hydroxypropylcellulose to use in various formulations.

Scope:

1.1 These test methods cover the testing of hydroxypropylcellulose.

1.2 The test procedures appear in the following order:

 

 

Sections

 

Moisture

4 – 9

 

Viscosity

10 – 16

 

pH

17 – 21

 

Residue on Ignition

22 – 28

 

Hydroxypropoxy Content

29 – 36

1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.4 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. For specific hazard statements, see 26.6.
