Introduction:
Carboxymethyl cellulose (C8H16O8) is a carboxylic acid derivative and biochemical compound. At room temperature, it appears as a white or slightly yellowish powder with no noticeable odor. Carboxymethyl cellulose, commonly referred to as CMC, is a water-soluble polymer derived from cellulose. Its structure consists of cellulose chains modified by the introduction of carboxymethyl groups, which impart unique properties such as viscosity modulation and emulsification. As a biochemical compound, it plays a crucial role in various industries due to its biocompatibility and ability to form stable gels or solutions.
