10016-20-3 - Product Introduction:

α-Cyclodextrin (α-CD) (CAS: 10016-20-3) is a non-reducing cyclic saccharide comprised of six glucose units linked by alpha-1.4 bonds. It is produced by the action of cyclodextrin glucosyl transferase on hydrolysed starch syrups. The cavity of alpha-Cyclodextrin is less than beta-Cyclodextrin, so it is used to allow formation of inclusion complexes with little molecules. The solubility degree of Alpha-Cyclodextrin in water is 14.5 g/100ml @25°C, so the situation that needs high solubility of cyclodextrin.

 

Alpha-cyclodextrin is widely used in the drugs, food, flavor and cosmetics. Alpha-cyclodextrin is also widely used in the field of pesticide and adjusting the metabolization of the crop and increasing the quantity of the crop. Especially the cyclodextrin and its ramification which developed by these years,some of them are the important solutizer,stablizer, releaser or the assist materials of the Entericcoated drugs,some of them are the materials of organic synthetical macromolecular stuff.

 

Food grade Alpha cyclodextrin with 6 glucose units has the smallest cavity of the parent cyclodextrins. It is useful for solubilizing,stabilizing or delivering small molecules, e.g. low molecular weight, flavor or fragrance compounds.Food grade Alpha cyclodextrin is being introduced to the food industry as a new soluble dietary fiber with convincing properties.

 

10016-20-3 - Application:

Cyclodextrin has a hole in the center of the ring structure, and an oxygen atom in which -CH- binds to glucoside. It is sulfur-aqueous, and the hydroxyl groups at the 2, 3 and 6 positions of glucose are hydrophilic. It can be used to complex other molecules into inclusion complexes by a weak van der Waals force. Many substances can be encapsulated by cyclodextrins, including noble gases, halogens, dyes, fragrances, medicines, foods, pesticides and preservatives. After encapsulation, its stability, volatility, solubility and reactivity are improved. The special effect of Cyclodextrin makes it a widely used encapsulation material.
1. The use of Cyclodextrin in the pharmaceutical industry can form encapsulation (encapsulation) with drugs, which can make (1) Unstable drugs stable; (2) Deliquescence, adhesion or liquid drug powderization; (3) Insoluble or insoluble drugs can be dissolved (solubilized), etc.
2. Use in pesticide industry cyclodextrin encapsulation stabilization, some pesticides can be stored and improve insecticidal efficacy.
3. Uses in the food industry cyclodextrin is used in the food industry, has the following effects: (1) Elimination and cover up the special odor; (2) The improvement and improvement of food tissue structure; (3) the alleviation and removal of bitter taste; (4) Antioxidant effect; (5) Preservation and optimization of flavor.
4. The use of Cyclodextrin in the daily chemical industry in cosmetic manufacturing can also be used as emulsifier and quality improver. It also has deodorization (such as in addition to halitosis) and antiseptic effects, can be used for toothpaste, tooth powder manufacturing.
5. Other uses in environmental protection can be used as a treatment agent of oily sewage. The aqueous solution of Cyclodextrin is used to clean the oil tank, and the waste liquid can be recovered and treated to obtain fuel oil.
6. The use of cyclodextrin in chemistry Cyclodextrin is a valuable chemical reagent. When it is present, the fluorescence intensity of fluorochrome will increase significantly, so it can be used for the analysis of proteins and amino acids. It can also be used to separate long chain organic compounds, racemes, etc.
In addition, the adsorbent made from Cyclodextrin can be used for chromatographic adsorption.

10016-20-3 - Application Areas:

Pharmaceutical:
1. To increase the solubility of biological availability
2. To improve the bioavailability
3. To adjust or control the releasing
4. To decrease the toxicities
5. To improve the stabilities
Cosmetic:
1. To suit for encapsulation of volatile compounds.
2. To increase shelf life of expensive flavours.
Food:
1.To prevent evaporation of volatile substances.
2.To get rid of the terrible smell.
3.To significantly enhance the effects of emulsification 

10016-20-3 - Biochem / Physiol Actions:

α-Cyclodextrin is found to form a firm complex with dietary fats. This way it decreases the bioavailability and absorption of fats. It is known to regulate triglyceride and leptin levels in serum. In rat models, α-Cyclodextrin is shown to induce insulin sensitivity and fecal fat excretion. Thus, α-Cyclodextrin is considered to be effective for treating obesity and metabolic syndromes.

10016-20-3 - Regulatory Status:

Included in the FDA Inactive Ingredients Database: α-Cyclodextrin (injection preparations); β-Cyclodextrin (oral tablets, topical gels); γ-Cyclodextrin (IV injections). Included in the Canadian List of Acceptable Non-medicinal Ingredients (stabilizing agent; solubilizing agent ); and in oral and rectal pharmaceutical formulations licensed in Europe, Japan, and the USA.
