The invention discloses a degerming and acaricidal agent, which comprises a plant compound extract and calcium acetate; the plant compound extract is the extract of pomelo peel, lophatherum gracile and persimmon leaf. In the raw materials for preparing the plant compound extract, the mass ratio of the shaddock peel, the lophatherum gracile and the persimmon leaf is (0.5-3): (2-3): 1. the invention also discloses a preparation method of the degerming and mite-removing agent, and discloses a hyperconcentration laundry detergent containing the degerming and mite-removing agent in a formula. According to the invention, the extracts of the pomelo peel, the lophatherum gracile and the persimmon leaf are obtained by an alcohol extraction and water precipitation method, and the extracts and calcium acetate form a degerming and mite-removing agent to generate a synergistic effect, so that remarkable bacteriostatic and mite-removing effects are obtained. By screening multiple surfactant combinations, the problem that cubic phase liquid crystal is formed due to overhigh surfactant concentration is solved, and the super-concentrated laundry detergent with the active matter content of more than 50% can be obtained. The super-concentrated laundry detergent has both antibacterial and mite-killing effects and safety, and has strong detergency. |
