Abstract
A fullerene-polysaccharide supramolecular hydrogel was constructed by carrying out a co-assembly of fullerene@hydroxypropyl-β-cyclodextrin, chitosan and bentonite, and displayed good antioxidant and antiglycation properties, and hence showed promising cosmetics applications. Benefitting from the cyclodextrin hydrophobic cavity, hydroxypropyl-β-cyclodextrin formed a stoichiometric 2 : 1 complex with fullerene, effectively enhancing the water solubility and biological activity of fullerene, and the encapsulation ratio of the prepared fullerene was calculated to be 79%. Results of oxygen radical absorbance capacity and pyrogallol autoxidation experiments showed high antioxidant activity displayed by the fullerene@HP-β-CD inclusion complex. The supramolecular inclusion was further co-assembled, using multiple hydrogen bonds and electrostatic interactions, with chitosan and bentonite to form a supramolecular hydrogel; this hydrogel was successfully used in antiglycation, with a glycation end products inhibition rate of 43.99% at a 10% sample concentration. Therefore, the fullerene-polysaccharide ternary co-assembly supramolecular hydrogel showed good antioxidant and antiglycation abilities, and the construction of the polysaccharide supramolecular hydrogel provided a new perspective for raw materials to consider in cosmetics applications.
