Problems solved by technology

[0005] At present, in addition to the need to improve the ease of rinsing, due to environmental pollution, humidity in the washing machine, etc., bacteria are easy to grow on clothes and affect health. Traditional laundry detergents have the function of removing visible dirt, but they do not have the function of inhibiting the washing process. The function of bactericidal, so there is also a demand for laundry detergent that provides antibacterial properties
Patent Document 4 discloses a kitchen cleaning agent composition, which is added with a quaternary ammonium salt cationic surfactant, which has a strong antibacterial and disinfection function, but its formula is not suitable for laundry detergent
