Abbreviation: CMC / CMC-Na

CAS Number: 9000-11-7

Product Type: Cellulose Ether / Water-soluble Polymer

Product Introduction

Carboxymethyl cellulose (CAS 9000-11-7) is a water-soluble polymer material obtained by chemical modification of natural cellulose, usually supplied in sodium salt form (CMC-Na). This product possesses excellent thickening, suspending, emulsifying, stabilizing, and film-forming properties, and is safe, non-toxic, and biodegradable.

CMC is widely used in the food, pharmaceutical, daily chemical, oil drilling, ceramics, papermaking, battery materials, and coating industries. It is one of the most widely used cellulose derivatives globally and an indispensable functional additive in many industries.
