Toothpaste CMC is an anionic linear macromolecular compound which is used as thickener. It is carboxymethyl cellulose which appears as white color powder with odorless & tasteless nature. This CMC is known to provide stability, optimum amount of foam generation, and smooth & fine texture to toothpaste. It also plays adhesion role in toothpaste for stabilizing its quality. Toothpaste CMC increases gel strength of solutions with decreased interfacial viscosity.
Generally, products with medium to high viscosity exhibit thixotropy. In the process of storage, having significant thixotropic carboxymethyl cellulose solution, stored for a time period, subsequently the shear force stoppage. Here CMC offers improved apparent viscosity. It is essential to increase the gel strength of solution in the toothpaste products. When adequate external force is employed, the interfacial viscosity is decreased, as well as gel flows.
