Embodiment 1
[0040] Gelatin 1%;
[0041] Gellan gum 0.4%;
[0042] Natural plant essential oil 5%;
[0043] Isobutylene maleic anhydride copolymer 0.4%;
[0044] Ethylene glycol 10%;
[0045] PEG-40 hydrogenated castor oil 6%;
[0046] Tween 20 2%;
[0047] Potassium chloride 0.1%;
[0048]Deionized water balance.
[0049] The preparation method of mosquito repellent gel of the present invention is:
[0050] Heat gelatin and gellan gum separately to dissolve, mix at 60°C after complete dissolution, dissolve isobutylene maleic anhydride copolymer in deionized water, slowly add to the colloid solution, and keep the solution at 60°C. Mix natural plant essential oil, ethylene glycol, PEG-40 hydrogenated castor oil, Tween 20, and part of deionized water evenly to obtain a homogeneous solution. Add the homogeneous solution of solubilized essential oil into the colloidal solution, keep stirring, keep the solution temperature between 45-60°C, stir for about 10 minutes, add aqueous potassiu...
Embodiment 2
[0052] Gelatin 3%;
[0053] Isobutylene maleic anhydride copolymer 0.8%;
[0054] Natural plant essential oil 3%
[0055] Ethanol 8%;
[0056] PEG-60 hydrogenated castor oil 6%;
[0057] Deionized water balance.
[0058] Heat the gelatin at 50°C to dissolve, dissolve the isobutylene maleic anhydride copolymer in deionized water, slowly add it into the colloid solution, and keep it warm at 40-45°C. Mix natural plant essential oil, ethanol, PEG-60 hydrogenated castor oil, and partially deionized water evenly to obtain a homogeneous solution. Add the homogeneous solution of solubilized essential oil into the colloidal solution, keep stirring, keep the temperature of the solution between 40-45°C, stir for about 15 minutes, discharge, fill and cool to room temperature, and the shaped gel can be obtained.
Embodiment 3
[0060] Carrageenan 1.5%;
[0061] 1% natural plant essential oil;
[0062] Polyacrylamide 0.2%;
[0063] Polyvinyl alcohol 1.8%;
[0064] Butanediol 5%;
[0065] PEG-40 hydrogenated castor oil 0.5%;
[0066] Isomerized alcohol polyoxyethylene ether 0.5%;
[0067] Potassium chloride 0.5%;
[0068] Deionized water balance.
[0069] Carrageenan and polyvinyl alcohol are heated to dissolve, polyacrylamide is dissolved in deionized water and added to the colloidal solution, and the colloidal solution is kept at 60°C. The natural plant essential oil, butylene glycol, PEG-40 hydrogenated castor oil, isomeric alcohol polyoxyethylene ether, and part of deionized water are evenly mixed to obtain a homogeneous solution. Add the homogeneous solution of solubilized essential oil into the colloidal solution, keep stirring, keep the solution temperature between 45-60°C, add potassium chloride aqueous solution, continue stirring at constant temperature for a period of time, discharge, ...
