LOT NO.: 260209

Product Introduction

Beta Cyclodextrin, commonly known as β-CD or Betadex, is a cyclic oligosaccharide composed of seven glucose units linked by α-1,4 glycosidic bonds. Its CAS number is 7585-39-9, molecular formula is C42H70O35, with a molecular weight of 1134.98 g/mol. Our product appears as a white crystal powder, odorless with a slightly sweet taste, produced through enzymatic conversion of starch under strict quality control conditions.

The unique molecular structure of beta cyclodextrin features a hydrophobic internal cavity and a hydrophilic external surface, allowing it to form inclusion complexes with a wide range of guest molecules. This property makes it an invaluable ingredient in various industries, where it is used to improve solubility, stability and bioavailability of active ingredients, mask unpleasant odors and tastes, and control release of volatile compounds.

Our beta cyclodextrin is manufactured with advanced production technology, with full batch traceability and complete supporting quality documents. We offer both standard grade and customized specifications to meet specific customer requirements and ensure long-term stable bulk supply for global manufacturers.

Technical FAQ

Q1: What is the inclusion capacity of beta cyclodextrin?

A1: Beta cyclodextrin typically forms 1:1 inclusion complexes with most guest molecules. The inclusion capacity depends on the size, shape and polarity of the guest molecule. Molecules with molecular weight between 100 and 300 g/mol and appropriate hydrophobicity are most suitable for complexation with beta cyclodextrin.

Q2: Is beta cyclodextrin safe for consumption?

A2: Yes, beta cyclodextrin is generally recognized as safe (GRAS) by the FDA and is approved for use as a food additive in most countries worldwide. It is also listed in major pharmacopoeias as a pharmaceutical excipient. It is non-toxic, non-irritating and biodegradable.

Q3: How do I prepare an inclusion complex with beta cyclodextrin?

A3: Common methods for preparing inclusion complexes include:

• Co-precipitation method: Dissolve beta cyclodextrin in water, add guest molecule, stir and cool to precipitate the complex
• Kneading method: Mix beta cyclodextrin with guest molecule and small amount of water to form a paste, then dry
• Freeze drying method: Dissolve both components in water, then freeze dry to obtain the complex
• Spray drying method: Suitable for large-scale industrial production

Q4: What is the difference between alpha, beta and gamma cyclodextrin?

A4: The main difference is the number of glucose units: alpha (6 units), beta (7 units) and gamma (8 units). This results in different cavity sizes: alpha (0.57 nm), beta (0.78 nm) and gamma (0.95 nm). Beta cyclodextrin is the most widely used due to its appropriate cavity size for many common guest molecules, good availability and cost-effectiveness.

Q5: Can beta cyclodextrin be used in organic solvent systems?

A5: Beta cyclodextrin is highly soluble in water but has low solubility in most organic solvents. However, modified beta cyclodextrins (such as hydroxypropyl-beta-cyclodextrin) have improved solubility in organic solvents and are suitable for non-aqueous applications.

Q6: What is the shelf life of beta cyclodextrin?

A6: Beta cyclodextrin has a shelf life of 24 months when stored in tightly sealed original containers under proper storage conditions. It is hygroscopic and will absorb moisture from the air, which can cause caking. Keep containers tightly closed when not in use and store in a dry place.
