It is produced from starch through enzymatic conversion. Beta-cyclodextrin is the 7-membered sugar ring molecular form of cyclodextrin. Cyclodextrin has various applications. In the pharmaceutical industry, it can be used as complexing agents for increasing the solubility of poorly soluble drug as well as increasing their bioavailability and stability. It can also alleviate the gastrointestinal drug irritation, and prevent drug-drug and drug-excipient interactions. It can also be used in food, pharmaceutical, drug delivery, and chemical industries, as well as agriculture and environmental engineering. References # # Chemical Properties white powder Chemical Properties Cyclodextrins occur as white, practically odorless, fine crystalline powders, having a slightly sweet taste. Some cyclodextrin derivatives occur as amorphous powders. Chemical Properties A biennial herbaceous plant very common in Europe, Asia, Africa and the United States, it has a tapering fleshy root, furrowed stem, finely cut feathery leaves, umbels of small flower heads in midsummer, and capsules containing two curved narrow seeds. The plant grows to about 60 cm and it blooms from May to July. The part used is the fruit, containing approximately 15% of fixed oils and 3 to 7% of essential oil. Caraway has a warm, biting flavor with a strong, fatty, harsh undernote. Chemical Properties beta Cyclodextrin is a virtually odorless, slightly sweet-tasting, white or almost white crystalline solid or fine powder. Occurrence A derivative of naturally occurring starch. Uses Use to solubilize non-polar compounds such as fatty acids, lipids and cholesterol. Reported useful for the selective precipitation of enantiomeric, positional or structural isomersβ-Cyclodextrin is used with dansyl chloride to form water-soluble complexes for fluorescent labeling of proteins. It is an active ingredient of household odor eliminator. It is also used in personal care products like toothpastes, skin creams and dusting powders. It finds applications in the cosmetic industry for products like detergents and perfumes for the controlled release of fragrances. Further, it is used to produce HPLC columns allowing chiral enantiomers separation. In addition to this, it is used to decrease the level of cholesterol in milk fat. Uses β-Cyclodextrin is a cyclic oligosaccharide produced from starch via enzymatic conversion. β-Cyclodextrin is commonly used to produce HPLC columns allowing chiral enantiomers separation. Production Methods Cyclodextrins are manufactured by the enzymatic degradation of starch using specialized bacteria. For example, β-cyclodextrin is produced by the action of the enzyme cyclodextrin glucosyltransferase upon starch or a starch hydrolysate. An organic solvent is used to direct the reaction that produces β-cyclodextrin, and to prevent the growth of microorganisms during the enzymatic reaction. The insoluble complex of β-cyclodextrin and organic solvent is separated from the noncyclic starch, and the organic solvent is removed in vacuo so that less than 1 ppm of solvent remains in the β-cyclodextrin. The β-cyclodextrin is then carbon treated and crystallized from water, dried, and collected. Preparation Usually produced commercially from Bacillus macerans or B. circulans fermentation of starch or starch hydrolysate. Essential oil composition In addition to carvone, the oil contains d-limonene, carveol, diacetyl furfural, methyl alcohol, acetic aldehyde and other substances. Caraway oil consists of 3.5 to 7% volatile and fatty oils; resin, sugar, tannin, mucilage. Taste threshold values Reported to have a taste threshold value lower than that of sucrose with a detection level of 3.9 to 27 ppm and a recognition level of 11 to 52 ppm General Description Beta-Cyclodextrin is the most abundant and cheap cyclic oligosaccharide that forms inclusion complexes with several drug molecules. Its main application is in tablet and capsule formulations. Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. Pharmaceutical Applications Cyclodextrins are ‘bucketlike’ or ‘conelike’ toroid molecules, with a rigid structure and a central cavity, the size of which varies according to the cyclodextrin type. The internal surface of the cavity is hydrophobic and the outside of the torus is hydrophilic; this is due to the arrangement of hydroxyl groups within the molecule. This arrangement permits the cyclodextrin to accommodate a guest molecule within the cavity, forming an inclusion complex. Cyclodextrins may be used to form inclusion complexes with a variety of drug molecules, resulting primarily in improvements to dissolution and bioavailability owing to enhanced solubility and improved chemical and physical stability. Cyclodextrin inclusion complexes have also been used to mask the unpleasant taste of active materials and to convert a liquid substance into a solid material. b-Cyclodextrin is the most commonly used cyclodextrin, although it is the least soluble. It is the least expensive cyclodextrin; is commercially available from a number of sources; and is able to form inclusion complexes with a number of molecules of pharmaceutical interest. However, b-cyclodextrin is nephrotoxic and should not be used in parenteral formulations. b-Cyclodextrin is primarily used in tablet and capsule formulations. In oral tablet formulations, b-cyclodextrin may be used in both wet-granulation and direct-compression processes. The physical properties of b-cyclodextrin vary depending on the manufacturer. However, b-cyclodextrin tends to possess poor flow properties and requiresalubricant,such as 0.1% w/w magnesium stearate,when it is directly compressed. In parenteral formulations, cyclodextrins have been used to produce stable and soluble preparations of drugs that would otherwise have been formulated using a nonaqueous solvent. In eye drop formulations, cyclodextrins form water-soluble complexes with lipophilic drugs such as corticosteroids. They have been shown to increase the water solubility of the drug; to enhance drug absorption into the eye; to improve aqueous stability; and to reduce local irritation. Cyclodextrins have also been used in the formulation of solutions,suppositories, and cosmetics. Biochem/physiol Actions β-Cyclodextrin is the cyclic α heptamer of glucose. It acts as a host to form inclusion compounds with the guests including derivatives of benzene, cyclohexane, adamantane, other alicyclic guests, and also inorganic molecules or ions. It is generally used to solubilize non-polar compounds such a fatty acids, lipids and cholesterol. Safety Cyclodextrins are starch derivatives and are mainly used in oral and parenteral pharmaceutical formulations. They are also used in topical and ophthalmic formulations. Cyclodextrins are also used in cosmetics and food products, and are generally regarded as essentially nontoxic and nonirritant materials. However, when administered parenterally, β-cyclodextrin is not metabolized but accumulates in the kidneys as insoluble cholesterol complexes, resulting in severe nephrotoxicity. Cyclodextrin administered orally is metabolized by microflora in the colon, forming the metabolites maltodextrin, maltose, and glucose; these are themselves further metabolized before being finally excreted as carbon dioxide and water. Although a study published in 1957 suggested that orally administered cyclodextrins were highly toxic, more recent animal toxicity studies in rats and dogs have shown this not to be the case, and cyclodextrins are now approved for use in food products and orally administered pharmaceuticals in a number of countries. Cyclodextrins are not irritant to the skin and eyes, or upon inhalation. There is also no evidence to suggest that cyclodextrins are mutagenic or teratogenic. β-Cyclodextrin LD50 (mouse, IP): 0.33 g/kg(16) LD50 (mouse, SC): 0.41 g/kg LD50 (rat, IP): 0.36 g/kg LD50 (rat, IV): 1.0 g/kg LD50 (rat, oral): 18.8 g/kg LD50 (rat, SC): 3.7 g/kg storage Cyclodextrins should be stored in a tightly sealed container, in a cool, dry place.Cyclodextrins are stable in the solid state if protected from high humidity.

Chemical Properties Sodium starch glycolate is a white or almost white free-flowing very hygroscopic powder. The PhEur 6.0 states that when examined under a microscope it is seen to consist of: granules, irregularly shaped, ovoid or pear-shaped, 30–100 mm in size, or rounded, 10–35 mm in size; compound granules consisting of 2–4 components occur occasionally; the granules have an eccentric hilum and clearly visible concentric striations. Between crossed nicol prisms, the granules show a distinct black cross intersecting at the hilum; small crystals are visible at the surface of the granules. The granules show considerable swelling in contact with water. Uses Sodium starch glycolate is widely used in oral pharmaceuticals as a disintegrant in capsule and tablet formulations. It is recommended to use in tablets prepared by either directcompression or wet-granulation processes. Uses Sodium Starch Glycolate is a starch of potato origin with α1-4 short linear linkages and branched α1-6 linkages between glucose units. Used in the synthesis of capsules for delivery of drugs or medicaments. Production Methods Sodium starch glycolate is a substituted derivative of potato starch. Typically, commercial products are also crosslinked using either sodium trimetaphosphate (Types A and B) or dehydration (Type C). Starch is carboxymethylated by reacting it with sodium chloroacetate in an alkaline, nonaqueous medium, typically denatured ethanol or methanol, followed by neutralization with citric acid, acetic acid, or some other acid. Vivastar P is manufactured in methanolic medium, and Explotab in ethanolic medium. Pharmaceutical Applications Sodium starch glycolate is widely used in oral pharmaceuticals as a disintegrant in capsule and tablet formulations. It is commonly used in tablets prepared by either direct-compression or wet-granulation processes. The usual concentration employed in a formulation is between 2% and 8%, with the optimum concentration about 4%, although in many cases 2% is sufficient. Disintegration occurs by rapid uptake of water followed by rapid and enormous swelling. Although the effectiveness of many disintegrants is affected by the presence of hydrophobic excipients such as lubricants, the disintegrant efficiency of sodium starch glycolate is unimpaired. Increasing the tablet compression pressure also appears to have no effect on disintegration time. Sodium starch glycolate has also been investigated for use as a suspending vehicle. Safety Sodium starch glycolate is widely used in oral pharmaceutical formulations and is generally regarded as a nontoxic and nonirritant material. However, oral ingestion of large quantities may be harmful. storage Tablets prepared with sodium starch glycolate have good storage properties. Sodium starch glycolate is stable although very hygroscopic, and should be stored in a well-closed container in order to protect it from wide variations of humidity and temperature, which may cause caking. The physical properties of sodium starch glycolate remain unchanged for up to 3 years if it is stored at moderate temperatures and humidity. Incompatibilities Sodium starch glycolate is incompatible with ascorbic acid. Regulatory Status Included in the FDA Inactive Ingredients Database (oral capsules and tablets).
