General description

α-Cyclodextrin (α-CD) is a cyclic oligosaccharide that consists of six glucopyranose units linked by α-(1,4) bonds. It is mainly used as a stabilizer for emulsions such as mayonnaise, margarine or butter creams.

Application

α-Cyclodextrin can form host-guest inclusion complexes with a wide variety of organometallics, which can as be used as a template for silica nanocasting to synthesize nanodisperse inorganic-organic hybrid materials. α-CD can undergo cross-linking with poly(ethylene oxide)s to form injectable and bioabsorbable supramolecular hydrogels.
