The invention belongs to the technical field of daily washing article, especially relates to an antibacterial liquid detergent. The antibacterial liquid detergent comprises the following components in parts by weight: 0.1-0.15% of a chelating agent, 10-20% of a nonionic surfactant, 5-9% of an anionic surfactant, 6-12% of an ampholytic surfactant, 0.05-0.1% of essence, 0.1-0.5% of a skin-protecting agent, 2.5% of a bactericide, 0.1-0.5% of an antiseptic, and 55-75% of deionized water. The antibacterial liquid detergent employs a complex formulation system of the nonionic surfactant, the anionic surfactant, and the ampholytic surfactant, and has good skin compatibility and sterilization decontamination capability. During a usage process, no precipitate is generated, no secondary pollution is generated, and environmental protection effect is realized; a product formula does not contain strong base and phosphor, the components have mild performance, are mild to skin and have no excitant performance. The antibacterial liquid detergent has the characteristics of safety, high efficiency, environmental protection, and good antibacterial effect.
