Embodiment Construction

[0024] Below in conjunction with embodiment the present invention is described in further detail.

[0025] Molecular distillation of commercially available essential oils is first carried out.

[0026] Carry out molecular distillation respectively to the commercially available sweet basil essential oil, vanilla oil and jasmine essential oil purchased in the wiped film type molecular distillation apparatus, specific method is as follows:

[0027] Set the feed temperature to 20-40°C, turn on the water circulation vacuum pump, slowly open the balance valve until no air bubbles are generated, close the balance valve and water circulation pump, add ice to the cold trap, turn on the mechanical vacuum pump, and adjust the vacuum degree to 200-400Pa. This example is 300Pa, degas until no bubbles are generated, then gradually adjust the vacuum degree to 5-25Pa, this example is 15Pa, carry out the first distillation at 20-45°C, and the distillation rate is 0.8-3mL / min , the present emb...

Abstract

The invention relates to mosquito-repelling sustained-release dropping pills and a preparation method.The mosquito-repelling sustained-release dropping pills are characterized by be prepared from an essential oil combination and a matrix, wherein the weight ratio of the essential oil combination to the substrate ranges from 1:1 to 1:8, and the essential oil combination is prepared from eucalyptus citriodora essential oil, basil sweet essential oil, vanilla oil, jasmine essential oil and synergist.The preparation method comprises the steps that the eucalyptus citriodora essential oil is melted, the basil sweet essential oil, the vanilla oil, the jasmine essential oil and the synergist are added, and the materials are stirred to be uniform; the mixture is added to the melted matrix and stirred to be uniform, and the constant temperature is maintained; the dropping pills are preparedin a pill dropping machine according to a specified technology.According to the mosquito-repelling sustained-release dropping pills and the preparation method, the usage quantity and order of use of the pills can be self-assembled according to different usage requirements and hobbies, and therefore single active ingredient slow-release quantity and slow-release duration of the essential oil are controlled, mosquitoes cannot produce insecticide resistance, the pills can be matched with multiple mosquito-repelling carriers for use, and the mosquito repelling effect is good.

Description

technical field [0001] The invention relates to a mosquito repellent product, in particular to a mosquito repellent slow-release dripping pill and a preparation method thereof. Background technique [0002] Common mosquito repellent products on the market include mosquito repellent toilet water, mosquito repellent lotion, mosquito repellent cream, mosquito repellent aerosol, mosquito repellent lotion, mosquito repellent lotion, mosquito repellent sheet, mosquito repellent patch, mosquito repellent gel, etc. Repellent products that act directly on the skin may cause discomfort and allergies to the human body. Sustained release dosage forms such as mosquito repellent tablets and mosquito repellent patches have problems such as uncontrollable sustained release time and difficult quality control; Rational use of chemically synthesized repellents has produced a series of problems, so there is an urgent need to research and develop healthy, environmentally friendly, safe and effec...
