Embodiment 1

[0021] A kind of floral water containing nanoemulsion of embedded golden bergamot essential oil, the parts by weight of each composition are as follows:

[0022]

[0023] The preparation method of above-mentioned nanoemulsion, comprises the following steps:

[0024] 1) Preparation of short-chain glucan: dissolve 10 g of waxy starch in water, heat gelatinization in an oil bath at 120° C., cool to 60° C., add pullulanase for debranching, and the addition of pullulanase The amount is 30 ASPU / g starch dry basis. After enzymolysis for 8 hours, centrifugation at 11000rpm for 5 minutes, put the supernatant in a water bath at a temperature of 100°C and keep it for 30 minutes to inactivate the enzyme to obtain short-chain glucan and its solution. Short-chain dextran and its solution are freeze-dried to obtain short-chain glucan powder.

[0025] 2) Preparation of octenyl succinic acid short-chain glucan: the short-chain glucan powder obtained in step (1) was formulated into an aqueo...

Abstract

The invention provides a preparation method of embedding citrus medica essential oil nanometer emulsion. The preparation method comprises the steps of preparing short-chain glucan; preparing octenyl succinate short-chain glucan; preparing octenyl succinate short-chain glucan nanometer particles; weighing octenyl succinate short-chain glucan nanometer particle powder to be dissolved into deionizedwater; adding Tween 80; performing ultrasonic processing until the solution is transparent; weighing citrus medica essential oil; dissolving the citrus medica essential oil into absolute ethyl alcohol; then, adding phosphatidylcholine; adding the citrus medica essential oil solution into the corresponding octenyl succinate short-chain glucan nanometer particle powder solution; performing shearingand homogenizing to obtain the octenyl succinate short-chain glucan-citrus medica essential oil nanometer emulsion. The invention also provides floral water, which is prepared from de-ionized water, glycerin, citric acid, cacumen platycladi, ethanol and the embedding citrus medica essential oil nanometer emulsion prepared by the method. The floral water is green and natural and has small irritation and fragrant smell.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a nanoemulsion, in particular to a preparation method of a nanoemulsion embedding golden bergamot essential oil and its application in toilet water. Background technique [0002] The toilet water on the market is mostly made of chemical reagents, long-term use, although it can play the effect of repelling mosquitoes, it will cause serious damage to people's skin, and sometimes even cause skin diseases, so there is an urgent need on the market for a Mosquito repellent, toilet water that does not cause damage to human skin comes out. [0003] The ternary system of octenyl succinic acid short-chain dextran nanoparticles refers to dextran with a degree of polymerization of about 20, which is formed by connecting glucose with α-1,4-glucosidic bonds. The branched chain can be hydrolyzed by pullulanase Starch gets. Its basic structural unit is the same as amylose, but the ternary system ...
