Embodiment 1

[0024] Example 1, the slow-release sachet raw material contains 14 to 15 parts of beta cyclodextrin, 50.5 to 51.5 parts of purified water, 2 to 3 parts of essential oil, 28 to 29 parts of ethanol aqueous solution, carboxymethyl Base cellulose 3 to 4 parts.

Embodiment 2

[0025] Example 2, as an optimization of the above example, the slow-release sachet raw material contains 14.58 parts by weight of β-cyclodextrin, 51.04 parts of purified water, 2.62 parts of essential oil, 28.41 parts of ethanol aqueous solution, and 3.35 parts of carboxymethyl cellulose .

Embodiment 3

[0026] Example 3, as an optimization of the above examples, the slow-release sachet is obtained by the following preparation method: the first step, the required amount of β-cyclodextrin is added to the required amount of purified water, at a temperature of 45 ° C to Stir and dissolve at 55°C, and obtain an aqueous solution of β-cyclodextrin after stirring and dissolving; in the second step, add the required amount of essential oil to the required amount of ethanol aqueous solution, and obtain an ethanol essential oil solution after stirring and dissolving; in the third step, add The ethanol essential oil solution is added to the β-cyclodextrin aqueous solution for inclusion at a temperature of 45°C to 55°C, and after inclusion, it is cooled to room temperature to obtain the inclusion liquid; the fourth step is to add the required amount of carboxymethyl cellulose Into the clathrate liquid, stir and mix evenly to obtain a viscous liquid; the fifth step, after the viscous liquid...

Abstract

The present invention relates to the technical field of household articles and relates to a slow-release sachet and a preparation method thereof; the slow-release sachet is made with the materials according to parts by weight: 14-15 parts of Beta-cyclodextrin, 50.5-51.5 parts of purified water, 2-3 parts of essential oil, 28-29 parts of ethanol solution and 3-4 parts of carboxyl methyl cellulose. The slow-release sachet of the invention can release fragrant odor slowly, can effectively reduce oxidization of the essential oil and keep stable and lasting fragrant ingredients and is used mainly in household articles such as sachets, pillows and cushions; the slow-release sachet can soothe nerves, ease pain and relieve depression and insomnia and can please a user; The slow-release sachet of the invention has pure odor without peculiar odors, has good slow-release effect and is constantly fragrant for 1.5-2 years, the raw materials are easy to obtain, production cost is greatly reduced, and the needs of people are met.

Description

technical field [0001] The invention relates to the technical field of household articles, and relates to a slow-release sachet and a preparation method thereof. Background technique [0002] Cyclodextrin (CD for short) is a general term for a series of cyclic oligosaccharides produced by amylose under the action of cyclodextrin glucosyltransferase produced by Bacillus, usually containing 6 to 12 D-pyridine glucopyranose unit. The molecular configuration of cyclodextrin is relatively special, its inner cavity is hydrophobic, while the outer cavity is hydrophilic, and has a special molecular structure of "inner hydrophobic, outer hydrophilic". According to the size of the cavity, it uses hydrophobic force, hydrogen bond and van der Waals force For molecular recognition, cyclodextrin has a strong adsorption capacity and is a kind of adsorption material with excellent performance. β-cyclodextrin has low solubility, easy to crystallize, separate, purify, non-toxic, and easy to...
