Uses
Reliable Data
In the papermaking industry, additives improve the tensile strength and smoothness of paper. During coated paper processing, viscosity modifiers are used to enhance the printability of paper. They can be added to the pulp as strengthening agents and also used for surface sizing. In addition, they can be used in the formulation of soap and synthetic detergents. In the petroleum industry, they are used as suspension stabilizers in drilling mud. In the food industry, they are used as thickeners, emulsion stabilizers, and ice crystal inhibitors in ice cream. In the textile industry, they serve as thickeners for printing and dyeing pastes. In the pharmaceutical industry, they can act as emulsion stabilizers in injections, binders and film-forming agents in tablets. In the production of cosmetics, ceramics, and other products, they are used as thickeners.
