- Cyclodextrins (sometimes called cycloamyloses) are a family of compounds made up of sugar molecules bound together in a ring (cyclic oligosaccharides). Cyclodextrins are produced from starch by means of enzymatic conversion. They are used in food, pharmaceutical and chemical industries, as well as agriculture and environmental engineering. A cyclodextrin is the chief active compound found in Procter and Gamble's deodorizing product "Febreze" under the brand name "Clenzaire". Cyclodextrins are composed of 5 or more α-D-glucopyranoside units linked 1->4, as in amylose (a fragment of starch). The 5-membered macrocycle is not natural. Recently, the largest well-characterized cyclodextrin contains 32 1,4-anhydroglucopyranoside units, while as a poorly characterized mixture, even at least 150-membered cyclic oligosaccharides are also known. Typical cyclodextrins contain a number of glucose monomers ranging from six to eight units in a ring, creating a cone shape. thus denoting: α -cyclodextrin: six membered sugar ring molecule β -cyclodextrin: seven sugar ring molecule γ -cyclodextrin: eight sugar ring molecule Assay: ≥98.0% Appearance: White or almost white crystalline powder Degree of Substitution: 3to 9 Loss on Drying: ≤4.5% Solubility: Clear, colorless solution Residue on Ignition: ≤0.5% Heavy Metals: ≤0.002% Residue Betadex: ≤ 0.1% Residue Propylene Glycol: ≤ 0.1% Chloride: ≤0.0002% Arsenic: ≤0.0004% Total Aerobic Count: ≤1000cfu/g Total Molds and Yeasts: ≤100cfu/g E.coli: Negative
