Our High Quality Beta-Cyclodextrin with CAS number 7585-39-9 is a well - recognized chemical compound in the market. Beta - Cyclodextrin is a cyclic oligosaccharide composed of seven D - (+) - glucopyranose units linked by α - 1,4 - glycosidic bonds. It has a toroidal or cone - shaped molecular structure with a hydrophilic outer surface and a hydrophobic cavity in the center.
Regarding its physical properties, it is a white, odorless, and slightly sweet powder. It is sparingly soluble in cold water but more soluble in hot water. The melting point of Beta - Cyclodextrin is around 290 - 305°C (decomposition). It has a molecular weight of approximately 1134.98 g/mol.
1. **Pharmaceutical Industry**: In the pharmaceutical field, Beta - Cyclodextrin is widely used as a drug carrier. It can form inclusion complexes with poorly soluble drugs, improving their solubility, stability, and bioavailability. For example, it can enhance the dissolution rate of some oral drugs, ensuring better absorption in the body. It can also mask the unpleasant taste and odor of drugs, making them more palatable for patients.
2. **Food Industry**: In the food sector, it serves as a flavor and aroma enhancer. It can encapsulate volatile flavor compounds, protecting them from oxidation, evaporation, and degradation. This helps in maintaining the flavor and quality of food products during storage. Additionally, it can remove unwanted substances such as cholesterol from food, offering a healthier option for consumers.
3. **Cosmetic Industry**: In cosmetics, Beta - Cyclodextrin is used to improve the stability and effectiveness of active ingredients. It can increase the solubility of lipophilic compounds in aqueous formulations, making them easier to incorporate into cosmetic products. It can also help in reducing the irritation potential of some ingredients.
1. **Preparation of Inclusion Complexes**: To prepare an inclusion complex with a guest molecule, dissolve an appropriate amount of Beta - Cyclodextrin in water under stirring and heating if necessary. Then, add the guest compound slowly while continuing to stir. The reaction usually takes place at room temperature or slightly elevated temperature for a certain period (e.g., several hours) to ensure complete complexation. After that, the solution can be cooled, and the inclusion complex may precipitate, which can be collected by filtration or centrifugation.
2. **Direct Addition in Products**: In some cases, Beta - Cyclodextrin can be directly added to products such as food, pharmaceuticals, or cosmetics during the manufacturing process. The dosage depends on the specific application and the requirements of the product. For example, in food products, the addition amount may range from 0.1% - 5% depending on the type of food and the purpose of use.
1. **Pharmaceutical Use Case**: A pharmaceutical company was developing an oral anti - inflammatory drug that had very poor solubility in water. By using Beta - Cyclodextrin to form an inclusion complex with the drug, the solubility of the drug increased by 5 - fold. As a result, the bioavailability of the drug in animal studies improved significantly, and in clinical trials, patients showed better therapeutic effects with lower doses of the drug. The unpleasant taste of the drug was also masked, increasing patient compliance.
2. **Food Use Case**: A beverage company wanted to enhance the flavor of its fruit - flavored drinks. They added Beta - Cyclodextrin to encapsulate the natural fruit flavors. During storage, the drinks maintained their strong and fresh fruit flavor for a much longer time compared to the control samples without Beta - Cyclodextrin. The consumers' feedback on the taste and quality of the drinks was highly positive, leading to an increase in sales.
3. **Cosmetic Use Case**: A skincare brand was formulating a facial serum containing a lipophilic antioxidant. The antioxidant was difficult to dissolve in the aqueous - based serum. By incorporating Beta - Cyclodextrin, the solubility of the antioxidant improved, and the serum became more stable. The product also showed better performance in protecting the skin from oxidative stress, and customer reviews indicated an improvement in skin texture and appearance.
