Problems solved by technology

However, 6-8 hours can not meet consumers' demand for mosquito repellent protection time
Therefore, the core problem of preparing mosquito repellent liquid at present is: reduce the absorption and evaporation of mosquito repellent components, delay the protection time, improve the use effect
However, no research has yet shown that mesoporous silica can be used for the slow release of mosquito repellent and applied to mosquito repellent (daily chemical products)

Embodiment 1

[0058] Mosquito repellants include:

[0059]

[0060] Add carbomer to water, stir to make it fully swell, and use it as the water phase; add ethyl butylacetamidopropionate, propylene glycol, and mesoporous silica nanoparticles to ethanol, stir until completely dissolved, and use it as the oil phase; Then mix the water phase and the oil phase and stir evenly; slowly add triethanolamine to adjust the pH to 5-7; finally add β-glucan, allantoin, menthol, ascorbyl glucoside, and rose hydrosol and stir evenly.

Embodiment 2

[0062] Mosquito repellants include:

[0063]

[0064]

[0065] Add carbomer to water, stir to make it fully swell, and use it as the water phase; add ethyl butylacetamidopropionate, propylene glycol, and mesoporous silica nanoparticles to ethanol, stir until completely dissolved, and use it as the oil phase; Then mix the water phase and the oil phase and stir evenly; slowly add triethanolamine to adjust the pH to 5-7; finally add hyaluronic acid, menthol, magnesium ascorbyl phosphate, resveratrol, and rose hydrosol and stir evenly.

Embodiment 3

[0067] Mosquito repellants include:

[0068]

[0069] Add carbomer to water, stir to make it fully swell, and use it as the water phase; add ethyl butylacetamidopropionate, propylene glycol, and mesoporous silica nanoparticles to ethanol, stir until completely dissolved, and use it as the oil phase; Then mix the water phase and the oil phase and stir well; slowly add triethanolamine to adjust the pH to 5-7; finally add ceramide, sorbitol, betaine, menthol, reduced glutathione, rose hydrosol and stir well That's it.

Abstract

The invention relates to the technical field of daily chemical products, in particular to mosquito-repelling liquid and a preparation method thereof. The invention provides the mosquito-repelling liquid with mesoporous silica nanoparticles, and the mosquito-repelling liquid has a sustained release effect on dimethyl phthalate by utilizing the characteristics that the mesoporous silica nanoparticles have high specific surface area and large pore volume, the pore channel structure, the pore diameter and the pore channel surface area property are easy to regulate and control, a cavity is easy to manufacture and the shell thickness is easy to regulate and control, so that the utilization rate and the protecting time of the dimethyl phthalate are increased and a good mosquito-repelling effect is achieved even if the concentration is low; furthermore, the irritation and the transcutaneous permeation of the dimethyl phthalate on the human body can be minimized by the load technology, and the safety and the effectiveness of the mosquito-repelling liquid are guaranteed; and an experiment shows that under a proper proportion, the effective mosquito-repelling time of the mosquito-repelling liquid provided by the invention can reach 13.1 hours and the repelling rate can still reach 78.3 percent after 18 hours.

Description

technical field [0001] The invention relates to the technical field of daily chemicals, in particular to a mosquito repellent liquid and a preparation method thereof. Background technique [0002] High temperature and high humidity in summer are the most serious seasons for mosquitoes and other blood-sucking insects. A large number of mosquito activities not only increase the risk of spreading related infectious diseases such as malaria, dengue fever, and Japanese encephalitis; they also seriously affect the normal work and life of residents because of itching and dermatitis caused by their bites and blood-sucking . For alleviating the harm of mosquitoes etc., when summer comes, mosquito repellent toilet water just becomes the hygienic product that people generally use. In summer, in large shopping malls and small stores all over the country, there will be a wide variety of toilet water for consumers to choose from on the shelves. Careful consumers, when purchasing mosqui...
