Applications
1. Pharmaceuticals
Drug Solubilizer & Stabilizer: Improves solubility and bioavailability of poorly water-soluble drugs through inclusion complexation.
Controlled Release Agent: Provides sustained or targeted drug delivery, especially for oral, nasal, and injectable formulations.
Taste Masking: Encapsulates bitter or unpleasant-tasting drugs.
Stabilization: Enhances thermal and photostability of drugs and biologics (e.g., peptides, steroids, vitamins).
2. Food Industry
Flavor Encapsulation: Traps volatile aroma and flavor molecules, preventing degradation and extending shelf life.
Cholesterol Removal: Used in dairy and egg processing to selectively remove cholesterol without affecting taste or nutrition.
Carrier for Nutrients: Improves dispersibility and stability of fat-soluble vitamins (e.g., A, D, E, K) and antioxidants.
Dietary Fiber & Prebiotic: Considered safe and digestible in small amounts, supporting gut health.
3. Cosmetics & Personal Care
Fragrance Stabilization: Protects and prolongs the release of volatile fragrance ingredients.
Active Ingredient Delivery: Enhances the penetration and efficacy of active cosmetic agents like retinoids or botanical extracts.
Improved Texture: Can help control viscosity and reduce stickiness in formulations.
4. Environmental & Industrial Uses
Pollutant Removal: Forms complexes with organic pollutants, pesticides, and heavy metals in environmental remediation.
Green Solvent System: Used in catalysis and chemical separations due to its biodegradable, non-toxic profile.
Textile & Polymer Applications: Used in smart materials to enable controlled release of fragrances or antimicrobial agents.
