Embodiment 1

[0034] Take 300mg of deoxycholic acid-hydroxypropyl chitosan and dissolve it in 50ml of water, stir well to form a homogeneous solution; take 15mg of Chitosan 60 Dissolve in 10ml toluene, stir well to C 60 completely dissolved. The aqueous solution of deoxycholic acid-hydroxypropyl chitosan was added dropwise to C 60 In the toluene solution, then continue to stir and mix for 4h, then evaporate the solvent to get C 60 - Deoxycholic acid-hydroxypropyl chitosan complex.

Embodiment 2

[0036] Take 300mg of deoxycholic acid-hydroxypropyl chitosan and dissolve it in ml water, stir well to form a homogeneous solution; take 60mgC 60 Dissolve in 20ml toluene, stir well to C 60 completely dissolved. The aqueous solution of deoxycholic acid-hydroxypropyl chitosan was added dropwise to C 60 In the toluene solution, then continue to stir and mix for 8h, then evaporate the solvent to get C 60 - Deoxycholic acid-hydroxypropyl chitosan complex.

Embodiment 3

[0038] Take 300mg of deoxycholic acid-hydroxypropyl chitosan and dissolve it in ml water, stir well to form a homogeneous solution; take 5mg of Chitosan 60 Dissolve in 2ml of toluene, stir well to C 60 completely dissolved. The aqueous solution of deoxycholic acid-hydroxypropyl chitosan was added dropwise to C 60 In the toluene solution, then continue to stir and mix for 2h, then evaporate the solvent to get C 60 - Deoxycholic acid-hydroxypropyl chitosan complex.

Abstract

The invention discloses an amphipathic chitosan-fullerene compound and a preparation method thereof. The preparation method comprises the following steps: dissolving amphipathic chitosan into a solvent to form an amphipathic chitosan solution, dissolving fullerene into the solvent to form a fullerene solution, dropwise adding the fullerene solution into the amphipathic chitosan solution, sufficiently mixing, and finally removing the solution out of the mixture solution so as to obtain the amphipathic chitosan-fullerene compound. The amphipathic chitosan-fullerene compound which has the moistening and anti-oxidation skincare effects is obtained by sufficiently mixing the amphipathic chitosan solution and the fullerene solution, the compound prepared from the amphipathic chitosan and the fullerene is high in stability, which is favorable for external use characteristics of compounds, and moreover the content of fullerene in a fullerene-amphipathic chitosan compound is increased, so that the use amount of the compound is reduced.

Description

technical field [0001] The invention relates to the field of fullerene functional materials, in particular to an amphiphilic chitosan-fullerene compound and a preparation method thereof. Background technique [0002] C 60 Fullerene is an allotrope of carbon like diamond and graphite. After years of research, it has been found that fullerene has multiple excellent properties, and it has a good performance in the fields of biology, medicine, optics, magnetism, energy and so on. Due to its special molecular structure, fullerene has excellent free radical scavenging performance, and free radicals add to C 60 Molecule formed after C 60 as the central inactive group, but this group does not participate in the free radical chain growth reaction in free radical oxidation, so C 60 is an antioxidant; at the same time in C 60 The free radical groups connected in the form of dimers on the carbon cage can also undergo reduction and elimination reactions, so C 60 Molecules that cata...
