The decomposition reaction of peroxide is intensified under the alkaline environment, the decomposition is inhibited under the acidic environment, the prior art uses volatile acid, such as acetic acid, which can continuously provide the acidic environment for the peroxide, however, the volatile acid substance has sharp taste, causes discomfort to people both in the production process and the use process, and forms acid mist at too high concentration, which threatens the health of people. In the process of research, the inventor finds that the acid without volatility can also play a certain inhibiting role, but the lasting effect improvement effect of the peroxide is lower. The inventors have further studied and found that when an organic acid containing a plurality of carboxyl groups is used, the number of acidic groups increases and the inhibitory action is improved; when a monocarboxylic acid having a specific structure, for example, a hydroxyl group-containing carboxylic acid, a benzene ring-containing carboxylic acid, a heterocyclic ring-containing carboxylic acid, or the like is used, the structure provides a certain degree of acidity enhancement, and the fabric washing resistance can also be improved.

The metal ions can be used as an auxiliary bactericide for peroxide sterilization, are adsorbed on the surface of fungi to destroy cell membranes to enter cells, enable cell components to escape, interfere cell metabolism, enable the cells to lose due biological functions and finally cause cell death. In fact, the addition of metal ions produces antimicrobial effects beyond the expectations of the inventors, which unexpectedly found that metal ions not only can compensate for the partial bactericidal effect of the peroxide from the inhibitory loss, but also can stabilize the effect of the peroxide, because metal ions can catalyze the decomposition of peroxide to some extent, and can act together with acidic substances in a certain ratio range, thereby balancing the bactericidal effect and the duration of the peroxide.
In some preferred embodiments, the weight ratio of the peroxide to the metal compound to the carboxylic acid is (2-6): (2-5): 1; more preferably, the weight ratio of the peroxide to the metal compound to the carboxylic acid is (3-5): (3-4): 1.
