Embodiment 1

[0013] Preparation of citronella oil / hydroxypropyl-β-cyclodextrin inclusion compound: get 500 grams of hydroxypropyl-β-cyclodextrin, dissolve in 500ml95% ethanol, add 50ml citronella oil. Stir in a blender at 2000 rpm for 20 minutes. Ethanol was recovered by distillation at 60°C, and then vacuum-dried to obtain 534 g of dry powder of the clathrate. Take the clathrate and make a 10% aqueous solution to form a stable suspension. The formation of citronella oil / hydroxypropyl-β-cyclodextrin inclusion complex can be proved from the infrared spectrum 1.

Embodiment 2

[0015] The preparation of citronella oil / methylation-beta-cyclodextrin clathrate: get methylation-beta-cyclodextrin 500 grams, be dissolved in the ethanol of 500ml95%, and add 50ml citronella oil, in blender Stir and clathrate at 2000 rpm for 20 minutes. Ethanol was recovered by distillation at 60°C, and dried in vacuum to obtain 542 g of dry powder of the clathrate. Take clathrate and make 10% clear aqueous solution. The formation of citronella oil / methylated-β-cyclodextrin inclusion complex can be proved from the infrared spectrum 2.

Embodiment 3

[0017] Application of citronella oil / methylated-β-cyclodextrin inclusion complex:

[0018] Take citronella oil / methylated-β-cyclodextrin inclusion complex, mix it with 10% aqueous solution, pack it aseptically, and make it into a spray to repel mosquitoes and flies, which can be used indoors and on people's clothing or skin. Spray to repel mosquitoes. It is also possible to add peppermint oil or other essential oils to the water-soluble clathrate for flavoring, and it can be made into a spraying agent as above.

Abstract

The invention discloses a preparation method and application of water-soluble insect-resistant and mosquito-repellent plant oil. The plant oil is included in a water-soluble cyclodextrin derivative to prepare a water-soluble inclusion compound. One or more kinds of inclusion compounds are taken for compounding to prepare a water spray agent or fumigant or powder used for insect prevention, mould prevention, bacteriostasis, freshness preservation and other aspects of grain, food materials, food, uncooked and cooked meat products and aquatic products. In addition, the plant oil can also be used for repelling mosquitoes and flies in a public environment to keep the environment sanitary. The plant oil has the advantages of being made from all natural plant ingredients without any organic solvent.

Description

technical field [0001] The invention relates to a method for encapsulating plant (essential) oil with a water-soluble cyclodextrin derivative to form a water-soluble clathrate to prepare a water-soluble insect-repelling and mosquito-repelling vegetable oil. Background technique [0002] Vegetable oils are a class of natural products. It is the unique aromatic substance extracted from plants, which has been widely used since ancient times. Because some vegetable oils contain mosquito repellent and antibacterial and antiseptic ingredients, they also have a good insect repellent and mosquito repellent effect. In some respects, it can replace chemical insect repellents, bactericidal and antifungal agents, and is used to prevent insects and mosquitoes, clean the environment, and protect food safety. [0003] In order to give full play to the mosquito-repelling, bactericidal and anti-mildew effects of vegetable oil, inclusion with cyclodextrin is the best solution. After the ve...
