Sterilization washing powder containing zinc pyrithione antibacterial agent and preparation method of sterilization washing powder

Abstract

The invention provides sterilization washing powder containing a zinc pyrithione antibacterial agent and a preparation method of the sterilization washing powder, and belongs to the technical field ofantibiosis. The sterilization washing powder containing the zinc pyrithione antibacterial agent is prepared by the following method: S01, preparing a composite antibacterial agent from a guanidine salt polymer and polyethylene glycol according to a ratio through a physical mixing method; S02, mixing the guanidine salt polymer / polyethylene glycol antibacterial agent with a zinc-loaded antibacterial agent, zinc pyrithione and dioctyl sodium sulfosuccinate to prepare the composite antibacterial agent containing zinc pyrithione. The composite antibacterial agent is added into a washing formula system such as washing powder, soap powder and the like and can be quickly dissolved and dispersed to release guanidine salt polymers, zinc ions and zinc pyrithione antimicrobial ingredients when clothes are washed and is easy to disperse in the washing process, and achieves the effects of quick sterilization and degerming.

Description

technical field [0001] The invention relates to the field of antibacterial technology, in particular to a sterilizing washing powder containing zinc pyrithione antibacterial agent which can be quickly dissolved in water and has the functions of sterilizing and degerming and a preparation method thereof. Background technique [0002] In recent years, with the improvement of people's economic level, the hygiene requirements in life are getting higher and higher. When washing clothes, consumers often add a certain amount of disinfectant. Common disinfectants on the market generally contain active ingredients such as sodium hypochlorite and hydrogen peroxide, but sodium hypochlorite and hydrogen peroxide have strong oxidizing properties, which may cause clothing to fade. If left on clothing, it will cause skin irritation and itching , It is easy to cause damage to household non-professional washing personnel. Therefore, it is very necessary to develop a milder, more efficient, ...

AI Technical Summary

Problems solved by technology

Zinc pyrithione is a white to yellow crystalline powder that exists in the form of suspensions in most products, such as shampoos and hand sanitizers, but if it is to be added to a solid matrix carrier, it needs to be resolved. Dispersion, hydrophilicity and other issues in the product, to ensure that the instant solubility of the overall detergent cannot be affected, it is necessary to carry out surface dispersion treatment and add surfactants for activation, but not all surfactants are compatible with pyridine sulfide. Zinc ketone can be matched. Some surfactants cannot give zinc pyrithione good hydrophilicity, and some non-ionic surfactants may reduce the activity of zinc pyrithione and reduce the effect of sterilization
