Chemical Structure and Properties

3. High Viscosity Grades High viscosity grades are essential in applications that require significant thickening or gelling properties. They are used in construction for mortar and other building materials, providing improved workability and adhesion.

In HEC, the hydroxyl (-OH) groups present in the cellulose molecule are partially substituted with hydroxyethyl groups (-O-CH2-CH2-OH). Typically, the degree of substitution ranges from 0.5 to 2.5, signifying that some of the hydroxyl groups of the cellulose are replaced with hydroxyethyl groups, which affects the solubility and viscosity of the compound. The introduction of these hydroxyethyl groups decreases intermolecular hydrogen bonding between the cellulose chains, enhancing solubility in water and other polar solvents.

Similarly, in the personal care segment, MHEC finds applications in lotions, creams, and shampoos. Its ability to thicken formulations while providing a smooth application makes it a preferred ingredient among cosmetic formulators.
