Standards for Sodium Carboxymethylcellulose/ Polyanionic cellulose

Sodium carboxymethylcellulose (CMC) and polyanionic cellulose (PAC) are widely used in various industries as thickeners, stabilizers, and rheology modifiers. To ensure their quality and safety, several standards have been established for these substances. Some of the most important standards for CMC and PAC are:

1. Food Chemicals Codex (FCC): This is a set of standards established by the US Pharmacopeial Convention (USP) for food ingredients, including CMC. The FCC sets standards for the purity, identity, and quality of CMC used in food applications.

2. European Pharmacopoeia (Ph. Eur.): The Ph. Eur. is a collection of standards for pharmaceutical substances used in Europe. It includes monographs for CMC and PAC, which establish the quality and purity requirements for these substances used in pharmaceutical applications.

3. American Petroleum Institute (API): The API sets standards for PAC used in drilling fluids in the oil and gas industry. The API specifies the properties, performance, and quality requirements for PAC used in drilling fluids.

4. International Organization for Standardization (ISO): The ISO has established several standards for CMC and PAC, including ISO 9001 (quality management system), ISO 14001 (environmental management system), and ISO 45001 (occupational health and safety management system).

5. Technical Association of the Pulp and Paper Industry (TAPPI): TAPPI has established standards for CMC used in the paper industry. These standards specify the performance and quality requirements for CMC used as a paper additive.

Overall, these standards help ensure the quality, safety, and consistency of CMC and PAC used in various industries. Compliance with these standards is important for manufacturers, suppliers, and end-users to ensure the effectiveness and safety of their products.
