Laundry detergent containing polylysine and chitosan as well as preparation method and application of laundry detergent

Abstract

The invention relates to a laundry detergent containing polylysine and chitosan. The laundry detergent contains the polylysine and the chitosan, wherein the weight ratio of the polylysine to the chitosan is 1:(5 to 35); the laundry detergent also contains citric acid by which the pH value of the laundry detergent is weakly acidic or neutral. According to the laundry detergent disclosed by the invention, the polylysine and the chitosan are combined and the dose ratio of the polylysine to the chitosan is optimized, so that the chitosan enhances sterilization effects of the polylysine on gram-positive bacterium, gram-negative bacterium and mould under the action of amino group, and particularly the long-effect sterilization effect of the laundry detergent is improved; further, a proper amount of the citric acid is added into the laundry detergent, and a stable weakly acidic-neutral system is formed by a balancing effect of the citric acid; the damage of the laundry detergent to clothes is reduced while a suitable action environment is provided for the polylysine and the chitosan; in addition, the flexibility of the clothes can be kept well, and original colors and textures of the clothes can be retained. The laundry detergent provided by the invention is comprehensive in effect and extremely-high in market promotion value.

Description

technical field [0001] The invention relates to the field of daily chemical industry, in particular to a laundry detergent containing polylysine and chitosan and a preparation method thereof. Background technique [0002] Laundry liquid is a new type of washing product. Its working principle is similar to that of traditional washing powder and soap. The active ingredients are surfactants. However, traditional washing powder and soap use anionic surfactants. Sodium alkyl sulfonate and sodium stearate are the main ones, which are highly alkaline and cause greater irritation and damage to the skin during use. Laundry liquid is mild to the skin when used, and after being discharged into nature, it degrades faster than washing powder, so it has become a new generation of detergent. [0003] Yet at present, although the short-term bactericidal effect of the existing laundry detergent is acceptable, the long-term bactericidal effect is not good, and the damage to clothing is relat...

Problems solved by technology

[0003] However, although the current existing laundry detergents have a good short-term bactericidal effect, their long-term bactericidal effect is not good, and they are more harmful to clothes.
