Abstract

The invention relates to a mosquito repellent and a preparation method thereof, belonging to the technical field of daily chemical engineering. The mosquito repellent is prepared from the following components: 25-40% of dimethyl phthalate, 0.5-1.2% of Carbomer 940, 10-15% of polyethylene glycol 400, 2-10% of propylene glycol, 2-10% of 95% ethanol, 5-10% of polyethylene glycol 6000, 0.5-2% of triethanolamine and balance of de-ionized water. The invention decreases the alcohol concentration, increases the dimethyl phthalate content, enables the skin to feel clean and cool in a similar way after smearing the gel type mosquito repellent under the condition of enhancing the effect by adjusting the solvent components, and achieves certain moisture retention and moistening effects on the skin after smearing the gel type mosquito repellent by the mutual cooperation of the propylene glycol and the polyethylene glycols 400 and 6000, thereby being applicable to personnel who perform long-term field operation.
