Problems solved by technology

Common solution type repellents have the following problems in use: (1) due to the rapid volatilization of DEET, the repellent duration is short (0.5-2 hours), which cannot meet the requirements of military field training; Greasy, poor comfort
(3) Since the ordinary solution type is easily absorbed by the human body, it may cause adverse reactions

[0035]

[0036]

[0037] Process:

[0038] 1. In phase A, heat all materials except disodium EDTA to 85°C, add disodium EDTA under stirring, homogenize for 5 minutes, keep stirring for 20 minutes to ensure complete dissolution.

[0039] 2. Mix the materials in phase B and stir for 5 minutes.

[0040] 3. After cooling phase A to 40°C, add dissolved phase B, stir for 10 minutes, and vacuum homogenize for 5 minutes.

[0041] 4. Add phase C, stir for 10 minutes, and continue to cool down to below 35°C. After passing the test, filter the material with a 200-mesh filter cloth below 30°C.

[0042] Remarks: This product is volatile and should be tightly sealed during storage.

experiment example

[0044] 1. Efficacy evaluation

[0045] (1) Laboratory repellent experiment effect:

[0046] Test method According to GB / T17322.10-1998 Pesticide Registration Insecticide Indoor Pesticide Efficacy Evaluation Method for Pesticide Efficacy Test. Before the experiment, the experimenters did a set of blank experiments to observe whether there was any significant difference in the attack power of mosquitoes against different experimenters, and selected 8 experimenters who passed the attack test. The selected experimenters wear latex gloves with 4cm×5cm exposed skin on the back of their hands, apply long-acting mosquito repellent gel on the exposed parts of the left and right hands at a dose of 8ul / cm2, put their hands into the cage and stay for 3min, test once every 1h, until Record the effective repelling time until one mosquito begins to attack. The results show that the long-lasting mosquito repellent cream ...

Abstract

The invention relates to a long-acting mosquito expelling gel and belongs to the field of daily chemical goods. The long-acting gel comprises an A phase, a B phase and a C phase in percentage by weight: the A phase: 40.00 to 60.00 percent of deionized water, 0.20 to 1.20 percent of carbomer resin, 0.05 to 1.00 percent of hydroxypropylmethyl cellulose and 0.01 to 1.00 percent of disodium EDTA; the B phase: 10.00 to 30.00 percent of alcohol, 10.00 to 25.00 percent of dimethyl phthalate, 0 to 10.00 percent of geranium extract and 0.01 to 1.00 percent of menthyl lactate; and the C phase: 0.10 to 1.00 percent of diisopropylamine. The long-acting mosquito expelling gel has a mild formulation, comfortable coating feel, is fresh and not sticky, has safe use and remarkable mosquito expelling effect which reaches over 10 hours and meets requirement of medicine specially needed for military.

Description

technical field [0001] The invention relates to the field of daily chemical products, in particular to a long-acting mosquito repellent dew. Background technique [0002] At present, the common anti-mosquito products on the market mainly fall into four categories: the first category is mosquito-killing aerosols, the second category is mosquito coils, the third category is repellents, and the fourth category is propellants that need to be diluted for use. The most commonly used are mainly the first three categories. [0003] Aerosol: mainly divided into two types according to different solvents. One is an oil-based type that uses kerosene as a solvent, and the other is a water-based type that uses water as a solvent. Generally speaking, the oil-based aerosol has a better insecticidal effect than the water-based aerosol because it can adhere to the mosquito body surface for a long time; however, the oil-based aerosol has a pungent smell and is not easy to be detected accept...
