Description

Cellulose Phosphate is a chemically modified cellulose derivative where phosphate groups are introduced onto the cellulose backbone, creating a versatile anionic polymer. This modification imparts unique properties such as ion-exchange capacity, thickening, and stabilization, making it a valuable functional ingredient. It is primarily utilized in the pharmaceutical, food, and cosmetic industries for its ability to control release, modify texture, and act as a suspending agent.

Application

• Pharmaceutical Excipient: Used as a disintegrant, binder, or controlled-release matrix in tablet formulations.
• Food Additive: Functions as a stabilizer, thickener, or dietary fiber supplement in various food products.
• Cosmetic Ingredient: Employed in creams and lotions for its emulsifying and viscosity-modifying properties.
• Ion-Exchange Resin: Serves as a medium for the purification and separation of proteins, enzymes, and other biomolecules.
• Biomedical Materials: Investigated for use in wound dressings and drug delivery systems due to its biocompatibility.
• Industrial Applications: Acts as a dispersant or binder in ceramic, paper, and textile processing.
