  • Applications

    β-Cyclodextrin (CAS 7585-39-9) is a cyclic oligosaccharide capable of forming inclusion complexes with many hydrophobic guests, which enables wide applications: in pharmaceuticals it enhances solubility, bioavailability, taste masking and controlled drug release; in foods it stabilizes flavors, reduces bitterness, removes cholesterol and extends shelf life; in cosmetics it fixes fragrances, lessens skin irritation and protects easily oxidized actives; in agriculture it provides slow release and safer handling of pesticides; in environmental remediation it captures and removes organic pollutants from water, soil and air; in analytical chemistry it serves as a separation and diagnostic agent; and in textiles and smart materials it enables controlled loading and release of functional molecules.
