example 1

[0020] Put 20 parts of refined wood vinegar into the enamel reaction kettle, then slowly add 1 part of surfactant OP-10 into it, stir and dissolve completely, then slowly add 3 parts of tea tree oil, stir until the solution is uniform and stable, record it as liquid A. Add 2 parts of tea tree oil into another enamel reaction kettle, and add 2 parts of DEET or 0.2 parts of pyrethroids under constant stirring until the solution is uniform and stable, which is recorded as liquid B. Under the action of constant stirring, slowly add liquid B to liquid A until the two solutions are clear, transparent, uniform and stable.

example 2

[0022] Put 40 parts of refined bamboo vinegar into the enamel reaction kettle, then slowly add 10 parts of surfactant Span 80 (SPAN) into it, stir and dissolve completely, slowly add 6 parts of eucalyptus oil, stir until the solution is uniform and stable, record Make liquid A. Add 4 parts of eucalyptus oil into another enamel reaction kettle, and add 3 parts of DEET or 0.3 parts of pyrethroids under the condition of constant stirring until the solution is uniform and stable and recorded as liquid B. Under the action of constant stirring, slowly add liquid B to liquid A until the two solutions are clear, transparent, uniform and stable.

example 3

[0024] Put 60 parts of refined bamboo (wood) vinegar into the enamel reaction kettle (including 40 parts of wood vinegar + 20 parts of bamboo vinegar), then slowly add 15 parts of surfactant dodecylbenzenesulfonic acid into it, and stir completely After dissolving, slowly add 9 parts of clove oil, stir until the solution is uniform and stable, and record it as liquid A.

Abstract

The invention discloses safe mosquito repellent containing bamboo wood vinegar liquid as well as a preparation method and an application thereof. The safe mosquito repellent containing bamboo wood vinegar liquid is characterized by comprising the following raw materials and auxiliary materials in parts by weight: 20-80 parts of refined bamboo wood vinegar liquid, 5-20 parts of plant essential oil, 1-20 parts of surface active agent, 2-5 parts of DEET and or 0.2-0.4 part of pyrethroid, wherein the refined bamboo wood vinegar liquid is one of or a mixture of refined bamboo wood vinegar liquid and refined wood vinegar liquid, and the refined bamboo wood vinegar liquid is distillate with the yield of lower than 95%, which is obtained by distilling or rectifying bamboo wood vinegar liquid stock solution. According to the preparation method, the refined bamboo wood vinegar liquid is obtained by rectifying, filtering and refining the natural bamboo (wood) vinegar liquid as the raw material, and then a right amount of natural essential oil and surface active agent are added to the refined bamboo wood vinegar liquid till the liquid is clear and transparent. The safe mosquito repellent containing bamboo vinegar prepared by the method is an environmental-friendly product which is safe in use and low in cost and has good specific effect.
