1. Basic Info
Name: Beta-cyclodextrin
Alias: β-Cyclodextrin, β-CD
CAS No.: 7585-39-9
Molecular Formula: C42H70O35
Molecular Weight: 1134.98
2. Physical & Chemical Properties
Physical Properties
- Appearance: White crystalline powder, odorless, slightly sweet taste
- Solubility: Slightly soluble in cold water, soluble in hot water; insoluble in ethanol, acetone, ether, hydrocarbons
- Melting behavior: Decomposes above 200 ℃ without distinct melting point
- Density (20℃): 1.42 g/cm3
- Hygroscopy: Slightly hygroscopic at high humidity
- Cavity structure: Annular hollow truncated cone, inner hydrophobic cavity, outer hydrophilic hydroxyl groups
- Optical property: Optically active, aqueous solution shows specific rotation
Chemical Properties
- Molecular structure: Cyclic oligosaccharide formed by 7 α-D-glucose units linked via α-1,4 glycosidic bonds
- Inclusion complexation: The hydrophobic inner cavity can encapsulate lipophilic small molecules to form inclusion complexes, improving solubility, stability and masking odor
- Hydroxyl reactivity: Multiple primary and secondary hydroxyl groups on outer surface, available for etherification, esterification, graft modification to produce HP-β-CD, M-β-CD derivatives
- Hydrolysis resistance: Cyclic structure resists acid hydrolysis better than linear starch; strong acid and high temperature will break glycosidic bonds to degrade into glucose
- Thermal stability: Stable below 150 ℃; gradual dehydration and carbonization over 200 ℃
- Photostability: Stable under light, no discoloration after long-term sealed storage
- Compatibility: Compatible with most water-soluble raw materials, plant extracts, drugs; incompatible with strong mineral acid, strong oxidants
3. Main Application Fields
1. Pharmaceutical Industry (Core Application)
- Solubilizer: Improve water solubility of poorly soluble APIs (steroids, flavonoids, fat-soluble vitamins)
- Stabilizer: Prevent drug oxidation, photodegradation, volatile loss; extend shelf life
- Taste masking agent: Cover bitter, pungent odor of oral medicines
- Slow-release carrier: Adjust drug release rate for sustained-release formulations
2. Food & Beverage Industry
- Food flavor stabilizer: Encapsulate spices, essential oils to reduce volatilization
- Antioxidant additive: Protect unsaturated oils and pigments from oxidative deterioration
- Deodorant: Remove fishy, bitter odor in meat, dairy, fruit drinks
- Food preservative auxiliary: Slow down mold growth
3. Cosmetic & Daily Chemicals
- Stabilizer for essential oil, plant active matter in essence, cream, mask
- Deodorant raw material for body wash, toothpaste, perfume; adsorb odor molecules
- Skin care active carrier, enhance transdermal absorption of lipophilic ingredients
4. Environmental & Analytical Chemistry
- Chromatographic stationary phase modifier for separation of chiral compounds
- Water treatment additive: Adsorb organic pollutants, aromatic hydrocarbons
- Laboratory inclusion reagent for separation and purification of organic monomers
5. Agricultural Raw Materials
Encapsulate pesticide active ingredients to reduce volatility, lower phytotoxicity and prolong efficacy
