Hydrogen peroxide stabilizing agent and hydrogen peroxide etching solution

The invention discloses a hydrogen peroxide stabilizing agent and a hydrogen peroxide etching solution, and belongs to the field of metal etching. The hydrogen peroxide stabilizing agent comprises alcoholic hydroxyl groups and ether bonds at the same time, and the number of carbon atoms in the hydrogen peroxide stabilizing agent is 3 to 12. When the hydrogen peroxide stabilizing agent having the abovementioned structure is applied to a hydrogen peroxide system metal etching solution, the decomposition of hydrogen peroxide can be inhibited prominently; moreover, when the etching solution containing the hydrogen peroxide stabilizing agent is used to etch a metal material, no metal is left on the surface of the etched metal material, and the uniformity of etching is improved. The provided hydrogen peroxide stabilizing agent can improve the using stability and service life of a hydrogen peroxide system etching solution, and guarantees the etching effect of the hydrogen peroxide system etching solution at the same time.
