从China供应商批发进口ã?â²-Cyclodextrin — FOB条款

β-cyclodextrin from Wuhan Silworld Chemical Co., Ltd. is a white crystalline powder with a minimum purity of 99%, produced via enzymatic conversion of starch. The compound forms inclusion complexes with hydrophobic molecules, which is central to its use in encapsulation and controlled release. Water solubility is high, and the molecular structure consists of seven glucose units arranged in a toroidal shape, with an outer hydrophilic shell and a hydrophobic cavity.

The material is supplied as a fine powder with a typical particle size distribution of 80-120 mesh and a moisture content of less than 5%. Standard bulk density ranges from 0.5 to 0.7 g/cm³, and the pH of a 1% aqueous solution is typically neutral to slightly acidic (6.0-7.5). It is thermostable up to 200°C, though prolonged exposure above 180°C may cause degradation. The product conforms to USP, EP, and food-grade standards, with heavy metal content typically below 10 ppm.

Primary applications include pharmaceuticals for drug solubility enhancement, food for flavour and colour stabilisation, and cosmetics for fragrance encapsulation. Industrial buyers often use it in agricultural chemicals to improve the stability of active ingredients. Packaging is standard 25 kg paper drums with inner polyethylene bags, though bulk bags are available on request. The product is shipped from Wuhan port, with lead times varying by season and order size.
