Abstract

The invention discloses a method for preparing a mosquito repellent by using a star anise oil extracted waste solution. The method comprises the following steps: firstly, extracting a mixture of anisic aldehyde, anisic ketone and anisic acid from the star anise oil extracted waste solution; secondly, mixing 30 to 50 parts of the mixture of the anisic aldehyde, the anisic ketone and the anisic acid, 10 to 20 parts of glycerol, 1 to 5 parts of eucalyptus robusta smith leaf oil, 2 to 20 parts of propylene glycol, 3 to 5 parts of polyoxyethylene sorbitan monooleate, 1 to 3 parts of sorbitan monopalmitate, 20 to 40 parts of folium eucalypti citriodorae hydrolat and 0.5 to 1 part of pyrrolidone-5-sodium carboxylate according to the mass ratio at the temperature of 75 DEG C and emulsifying to obtain the mosquito repellent. The method is simple to operate; the prepared product can effectively prevent mosquitoes, and is environmentally-friendly, low in cost and convenient to popularize and use.

Description

technical field [0001] The invention relates to a method for preparing a mosquito repellent, in particular to a method for preparing a mosquito repellent by using star anise oil to extract waste liquid.
