Antibacterial liquid laundry detergent, preparation method and applications thereof

Abstract

The invention belongs to the field of daily chemicals, and specifically relates to an antibacterial liquid laundry detergent, a preparation method and applications thereof. The antibacterial liquid laundry detergent comprises the following components in percentage by weight: 0.3 to 0.9% of composite antibacterial agent, 5 to 20% of anionic surfactant, 5 to 20% of nonionic surfactant, 0.05 to 0.5% of fluorescent whitening agent, 0.05 to 5% of chelating agent, 0 to 1% of pH adjuster, 0.1 to 1% of essence, and the balance being water. The composite antibacterial agent is prepared according to a mass ratio of 1:1-5 of nano silver to a plant origin antibacterial agent. The nano silver and plant origin antibacterial agent can generate a synergetic effect, the antibacterial activity is largely improved, and thus the bacteria can be effectively removed. Furthermore, the raw materials are easily available, the preparation technology is simple, the cost is low, and the preparation method can be applied to industrial production. The prepared antibacterial liquid laundry detergent is nontoxic, nonirritant, and environment-friendly and can be easily degraded by organisms.

Description

technical field

[0001] The invention belongs to the field of daily chemicals, and in particular relates to an antibacterial laundry detergent and a preparation method and application thereof. Background technique

[0002] Laundry detergent is a common clothing or textile washing product. Currently commercially available laundry detergents generally only have the following functions: washing, softening and finishing functions, rarely have antibacterial and sterilizing functions, and cannot meet the requirements for comprehensive cleaning of clothing, especially textiles and clothing in public places such as hotels and hotels. Also need to add disinfectant additionally when washing, and this is extremely inconvenient when washing.

[0003] Chinese patent (Application No.: 200810101768.2) discloses a bactericidal laundry detergent, which uses the extract of Bacillus subtilis CGMCC2294 fermentation broth as a bactericide. Chinese patent (application number: 201310613125.7) dis...
