The present invention provides a composition of a polyethylene glycol maleimide derivative and a polymerization inhibitor. In particular, the present invention provides a composition of an 8-arm polyethylene glycol maleimide derivative and a phenolic polymerization inhibitor. The ingredient and content of the polymerization inhibitor in the composition are reasonably chosen, thereby significantly increasing stability of the polyethylene glycol maleimide derivative, effectively avoiding the undesirable effect of gel solidifying due to polymerization during storage and transportation, and extending a pot life and shelf life of a product thereof.

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.

The present invention discloses polyglycol epoxide crosslinked sodium hyaluronate gel for injection and a preparation method thereof. A polyglycol epoxide is a compound with single molecular weight preferably; a plurality of ether bonds are present in the molecule of the polyglycol epoxide, the water solubility is good, and thus, the polyglycol epoxide is more easily subjected to a crosslinking reaction with polysaccharides; and meanwhile, polyglycol is relatively easy in adjustment of the number of repeating units and relatively easy in control of length, and thus, the sodium hyaluronate gel prepared by taking the polyglycol epoxide as a crosslinker is relatively easy in regulation and control of properties. The crosslinked sodium hyaluronate gel is low in toxicity, little in residual, small in squeezing and pushing force, good in shaping performance, good in enzyme resistance and long in in-vivo retention time. The present invention further discloses a mild crosslinker deactivation technology. Unreacted epoxide groups in the gel are subjected to a hydrolysis reaction in a carbonate buffer system with a pH of 8-9, so that the difficulty of impurity removal of the crosslinked sodium hyaluronate gel can be effectively lowered, and the problem of toxicity in the prior art due to the fact that BDDE is used in a crosslinking method is avoided.
