Applications
1. Pharmaceutical Industry
Drug Solubilization: Enhances solubility and bioavailability of hydrophobic drugs by encapsulating them in its cavity.
Stabilization of APIs: Protects active pharmaceutical ingredients (APIs) from hydrolysis, oxidation, and photodegradation.
Controlled Drug Delivery: Allows for sustained and targeted drug release, reducing side effects.
Taste and Odor Masking: Masks unpleasant tastes or odors of oral drug formulations.
2. Food and Beverage Industry
Flavor and Aroma Retention: Encapsulates volatile compounds, preventing degradation during storage and processing.
Cholesterol Reduction: Removes cholesterol from dairy products (e.g., milk, butter, eggs) without affecting texture or taste.
Encapsulation of Nutrients: Stabilizes and delivers sensitive compounds like vitamins and antioxidants.
3. Cosmetics and Personal Care
Fragrance Stabilization: Controls release and longevity of fragrances in perfumes, lotions, and sprays.
Skin Care Formulations: Helps deliver active ingredients like retinoids or peptides in a stable, non-irritating form.
Reduction of Greasiness: Provides a dry, silky feel to formulations with oily ingredients.
4. Industrial and Environmental Applications
Catalysis Support: Used in green chemistry for selective catalysis and enzyme immobilization.
Pollutant Removal: Binds hydrophobic organic pollutants in aqueous environments for water purification.
Textile and Packaging: Incorporated into smart materials for slow release of functional agents (e.g., antimicrobials, fragrances).
