One of the most significant attributes of CMEC is its water solubility. Unlike its parent cellulose, which is insoluble in water, CMEC can easily dissolve in both hot and cold water, forming a viscous solution. This property is primarily due to the presence of carboxymethyl groups that introduce ionic character and enhance intermolecular interactions with water. The degree of substitution of carboxymethyl groups on the ethyl cellulose backbone influences its solubility and viscosity. This tunability makes CMEC suitable for various formulations where specific viscosity and rheological properties are required.

Cellulose is one of the most prevalent organic compounds found on Earth, forming the structural basis of plant cell walls and serving as a primary component in the complex tapestry of life. As a polysaccharide, cellulose is composed of numerous repeating units of d-glucose, a simple sugar. In this article, we will explore the structural composition of cellulose, its functional roles in nature, and its significance in various fields, including industry and environmental sustainability.
