  • Patent number: 11202796
    Abstract: The present invention discloses a branched polyethylene glycol epoxy derivative crosslinked sodium hyaluronate gel, preparation and application thereof. The crosslinking agent used in the crosslinked sodium hyaluronate gel prepared by the present invention is a polyethylene glycol epoxy derivative, due to the existence of multiple ether bonds in the molecule of the crosslinking agent, there are more hydrogen bonds in the gel system; meanwhile, due to the particularity of the space structure of the branched polyethylene glycol epoxy derivative, the gel prepared has a more complex winding structure in its space, thus achieving better stability. Moreover, the branched polyethylene glycol epoxy derivative involved in the present invention is a compound with single molecular weight, therefore, the gel prepared thereby has better batch stability.
