Description

Cellulose Sulfate is a water-soluble, anionic polysaccharide derivative produced by the sulfation of cellulose. This modification imparts valuable properties such as high viscosity, gel-forming ability, and polyelectrolyte behavior, making it a versatile functional polymer. It is essential for industries requiring natural, bio-based thickeners, stabilizers, and rheology modifiers. Key sectors utilizing this compound include pharmaceuticals, cosmetics, food technology, and biomedical research.

Application

• Pharmaceuticals: Used as a viscosity-enhancing agent, stabilizer in suspensions and emulsions, and as a component in controlled-release drug delivery matrices.
• Cosmetics & Personal Care: Functions as a thickener, film-former, and stabilizer in creams, lotions, gels, and hair care products.
• Food Industry: Acts as a texture modifier, thickener, and stabilizer in various food products, leveraging its natural origin.
• Biomedical Research: Employed in cell culture as a substrate and in tissue engineering for creating hydrogel scaffolds.
• Industrial Applications: Serves as a dispersant, binder, and rheology modifier in coatings, ceramics, and other specialty formulations.
• Laboratory Reagent: Used in biochemical and biophysical studies due to its polyanionic character.
