Embodiment 1

[0023] Embodiment 1: Porous cornstarch described in the present invention is made by following steps:

[0024] A certain amount of cornstarch was placed in a flat-bottomed flask, and a disodium hydrogen phosphate-citric acid buffer solution with a pH value of 4.3 was added to make a starch suspension with a concentration of 15wt%. The mixed enzyme solution composed of glucoamylase in a weight ratio of 1:1.5 was reacted at 50°C for 12 hours, and the pH value was adjusted to 8.5 to terminate the reaction; centrifugal separation, suction filtration, dehydration, washing with distilled water 4 times, drying at 35°C, pulverization, and filtration 150 mesh sieve porous cornstarch.

Embodiment 2

[0025] Embodiment 2, a kind of mosquito repelling gel containing Artemisia argyi essential oil

[0026] The mosquito repellent gel described in Example 2 of the present invention is composed of the following components in parts by weight: 0.8 parts of carbomer, 1 part of porous corn starch, 5 parts of Artemisia argyi essential oil, 2 parts of polyethylene glycol, and 0.8 parts of laurozazone 6 parts of PEG-40 hydrogenated castor oil, 0.5 part of preservative and 50 parts of water.

[0027] Preparation:

[0028] Take carbomer and porous cornstarch, add water, stir evenly, let it stand for swelling, add hydrochloric acid, adjust the pH to 2.3, add Artemisia argyi essential oil, PEG-40 hydrogenated castor oil, lauroxazone and preservatives, stir and mix Add polyethylene glycol after uniformity, slowly add triethanolamine after mixing to adjust the pH to 7.6, fill it with 100g / bottle while it is hot, and cool to room temperature to obtain the product.

Embodiment 3

[0029] Embodiment 3, a kind of mosquito repelling gel containing Artemisia argyi essential oil

[0030] The mosquito repellent gel described in Example 3 of the present invention is composed of the following components in parts by weight: 0.5 parts of carbomer, 0.5 parts of porous corn starch, 3 parts of Artemisia argyi essential oil, 0.1 parts of polyethylene glycol, and 0.5 parts of laurozone 3 parts of PEG-40 hydrogenated castor oil, 0.1 part of preservative and 30 parts of water.

[0031] Preparation:

[0032] Take carbomer and porous cornstarch, add water, stir evenly, let it swell, add hydrochloric acid, adjust the pH to 2.0, add Artemisia argyi essential oil, PEG-40 hydrogenated castor oil, lauroxazone and preservatives, stir and mix Add polyethylene glycol after uniformity, slowly add triethanolamine after mixing to adjust the pH to 7.3, fill it with 100g / bottle while it is hot, and cool to room temperature to obtain the product.

Abstract

The invention belongs to the field of daily necessities, and particularly relates to a mosquito repelling gel containing folium artemisiae argyi essential oil and a preparation method thereof. The mosquito repelling gel is prepared from, by weight, 0.5-1 part of carbomer, 0.5-2 parts of porous maize starch, 3-6 parts of folium artemisiae argyi essential oil, 0.1-3 parts of polyethylene glycol, 0.5-1 part of laurocapam, 3-8 parts of PEG-40 hydrogenated castor oil, 0.1-1 part of preservative and 30-60 parts of water. The mosquito repelling gel is environmentally friendly and poisonless and harmless, does not need to make direct contact with the human body, has no harmful effect on the human body or the environment and is stable and lasting in mosquito repelling effect, the effective mosquito repelling time of the product of 100 g reaches up to 40 days which is much longer than that of a product available in the market, and the mosquito repelling gel is stable in system.

Description

technical field [0001] The invention belongs to the field of daily necessities, and in particular relates to a mosquito repellent gel containing mugwort essential oil and a preparation method thereof. Background technique [0002] The existence of mosquitoes not only affects the work and sleep of human beings, but also is the carrier of various diseases. It has been confirmed that there are more than 60 kinds of diseases that mosquitoes can transmit. The active ingredients of commonly used insecticides are all pyrethroids. Such insecticides will cause mosquitoes to develop drug resistance, and the toxicity of such insecticides itself also threatens human health. Therefore, many researchers now turn their attention to repellents. The use of repellents prevents mosquitoes from coming into contact with the human body, and mosquitoes will not develop drug resistance. The commonly used repellents on the market are chemically synthesized mosquito repellent oil, DEET and mosquito ...
