The present invention relates to a pet sterilizer and deodorizer, which belongs to the technical field of pet deodorization. The present invention promotes the long-term expression of hop extract and enhances the sterilization and deodorization effect through the synergistic effect of hop extract, persimmon
tannin, and
lysozyme. Furthermore, the composition is stable, natural, and
pollution-free, and can be used in the
oral cavity and
in vitro of animals. The present invention also provides
zinc ricinoleate and an
antibacterial agent. Through the three-phase interaction of
zinc ricinoleate, hop extract, and
antibacterial agent, the overall stability is enhanced and the antibacterial time of the complex is prolonged while ensuring antibacterial and deodorizing effects. The present invention also provides a modified
quaternary ammonium salt antibacterial liquid. The modified
quaternary ammonium salt has enhanced stability and, when present together with
zinc ricinoleate, promotes an enhanced deodorizing effect. The present invention also provides an
Artemisia annua extract, a
Gentiana root extract, and an
Artemisia argyi extract, which can eliminate
odor sources and significantly inhibit
bacterial growth, thereby having significant antibacterial, deodorizing, and
odor-removing effects.
