Description

Cationic Starch Phosphate

Cationic Starch Phosphate is a chemically modified polysaccharide combining cationic functional groups and phosphate substitution on a starch backbone. It is used in pharmaceutical, biomedical, and research applications where enhanced electrostatic interaction, binding capacity, and hydration properties are required.
Cationic Starch Phosphate appears as a white to off-white powder that disperses in water to form viscous solutions or pastes depending on molecular weight and degree of substitution. The presence of both cationic and phosphate groups provides a dual functionality, enabling interaction with a wide range of charged molecules and biological systems.
In pharmaceutical and research applications, Cationic Starch Phosphate is used in:
• Tablet binding and granulation systems
• Controlled-release and matrix-based delivery platforms
• Mucoadhesive and bioadhesive formulations
• Encapsulation and stabilization of active ingredients
• Surface modification of biomaterials and particles
• Studies involving polymer–protein and polymer–cell interactions
Cationic Starch Phosphate functions by combining electrostatic attraction from cationic groups with hydration and buffering characteristics from phosphate substitution. This dual modification supports improved adhesion, dispersion, and controlled interaction in complex formulation systems.
