Description

Cationic Starch

Cationic Starch is a chemically modified starch derivative containing positively charged functional groups, typically quaternary ammonium moieties, introduced onto the starch backbone. It is used in pharmaceutical, biomedical, and research applications where enhanced adhesion, electrostatic interaction, and binding capacity are required.
Cationic Starch appears as a white to off-white powder that disperses in water to form viscous solutions or pastes depending on degree of substitution and molecular weight. The cationic functionality improves interaction with negatively charged surfaces, polymers, proteins, and biological membranes.
In pharmaceutical and research applications, cationic Starch is used in:
• Tablet binding and granulation systems
• Mucoadhesive and bioadhesive drug delivery platforms
• Encapsulation and controlled-release formulations
• Surface modification of particles and biomaterials
• Gene delivery and nucleic acid complexation research
• Studies involving polymer–cell and polymer–protein interactions
Cationic Starch functions by providing electrostatic attraction to anionic substrates while retaining the biodegradability and biocompatibility of native starch. This combination supports improved adhesion, retention, and delivery efficiency in a variety of formulation systems.
CarboMer supplies cationic Starch with defined substitution levels, consistent molecular characteristics, and high purity suitable for regulated pharmaceutical research and advanced formulation development.
The material is packaged in sealed, moisture-resistant, tamper-evident containers to preserve stability and handling performance. Available in laboratory and pilot-scale quantities. Documentation includes Certificate of Analysis (CoA), Safety Data Sheet (SDS), and full traceability.
Each batch is tested for identity, degree of substitution, viscosity, moisture content, ash content, and microbial limits. Technical support is available to assist with formulation design, processing optimization, and application development.
As with all CarboMer supplied functionalized polysaccharides, cationic Starch is supported by dependable global supply, rigorous quality systems, and expert technical guidance to ensure consistent and reliable performance across pharmaceutical and research applications.
