2-hydroxypropyl-α-cyclodextrin NEW

1. Pharmaceutical Excipient & Drug Delivery

• Solubilization & Bioavailability: Dramatically improves water solubility of poorly soluble drugs (e.g., antifungals, antivirals, anticancer agents) via inclusion complexation, enhancing oral/parenteral absorption and reducing dose-related side effects.

• Parenteral Carrier: Safe for injections (low pyrogenicity, low hemolytic potential); stabilizes drugs against light/oxidation and reduces injection-site irritation.

• Controlled Release: Modulates drug release kinetics for sustained or targeted delivery.

• Taste Masking: Masks bitter tastes in oral formulations (syrups, suspensions).

• Gene Delivery: Cross-linked with polyethylenimine to form non-viral vectors for DNA binding and delivery.

2. Cosmetics & Personal Care

• Active Stabilization: Protects fragrances, essential oils, UV filters, and actives (e.g., retinol, ferulic acid) from degradation, extending shelf life.

• Skin Penetration: Enhances permeability of lipophilic actives (niacinamide, vitamin E) while reducing irritation.

• Odor Control: Masks unpleasant smells in formulations.

3. Food & Beverage

• Flavor/Color Stabilization: Encapsulates and protects flavors, aromas, and natural colors from oxidation/volatilization.

• Nutrient Protection: Stabilizes lipophilic nutrients (vitamins, antioxidants) in functional foods.

• Bitterness Reduction: Masks bitter notes in plant-based proteins and functional beverages.

4. Analytical Chemistry

• Chiral Selector: Used in capillary electrophoresis for enantiomeric separation (e.g., tryptophan racemates).

• Stationary Phase Additive: Improves separation of small hydrophobic compounds in HPLC/GPC.

5. Biotechnology & Materials

• Polyrotaxane Synthesis: Builds biodegradable polyrotaxanes for blood-contacting medical devices.

• Protein Stabilization: Protects proteins/enzymes from denaturation in buffers and bioprocesses.

6. Antimicrobial Stabilization

• Iodine Complexation: Forms stable, water-soluble inclusion complexes with iodine, enhancing its solubility and stability for use as a disinfectant/antiseptic.
