Embodiment 1

[0025] The complex coacervation multinuclear plant essential oil sustained-release microcapsule described in this embodiment is formed by coating the plant essential oil core material with natural alkaline polysaccharide-chitosan and natural vegetable gum-acupuncture gum as a composite wall material; The complex condensed multinuclear plant essential oil sustained-release microcapsules have a regular spherical multinuclear structure, and the multinuclei are evenly dispersed; the average particle diameter of the complex condensed multinuclear plant essential oil sustained-release microcapsules is 95 μm; the loading capacity of the plant essential oil exceeds the complex Condensing 65% of the volume of the cavity of the plant essential oil in the multinuclear plant essential oil sustained-release microcapsules; the plant essential oil is composed of aromatic volatile oil and plant base oil, and the aromatic volatile oil is composed of perrin oil ( Eupatorium fortunei ), rosemary ...

Embodiment 2

[0034] The method is the same as in Example 1, the difference is that the plant essential oil microcapsules are added to the daily chemical essence formula according to the mass ratio of 10%, and a fresh and refreshing washing and care essence can be obtained. Compared with the uncoated essential oil, the usage amount is reduced by 2 %, the aroma stability period is extended for 12 months.

Embodiment 3

[0036] The same as the method of Example 1, the difference is that the plant essential oil microcapsules are added to the cosmetic formula according to the mass ratio of 3%, and the antibacterial massage oil can be obtained. Compared with the uncoated essential oil, the aroma stability period is extended by 12 months, The proportion of skin irritation evaluation decreased by 15%.

[0037] Compared with the prior art, the present invention has the following advantages:

[0038] (1) The complex coacervated multinuclear plant essential oil sustained-release microcapsules of the present invention have a spherical multinuclear shape and structure, and have good controlled release and sustained release functions;

[0039] (2) The complex coacervated multinuclear plant essential oil sustained-release microcapsules of the present invention have uniform particle size, moderate size, average 95 μm, good dispersibility, high yield, high loading capacity, and the loading capacity of plant...

Abstract

The invention discloses a complex coacervation multicore plant essential oil slow-release microcapsule which is formed by coating a core material of plant essential oil with natural alkaline polysaccharide-chitosan and natural plant gum-Arabic gum which are taken as compound wall materials; the complex coacervation multicore plant essential oil slow-release microcapsule adopts a regular spherical multicore structure, and a plurality of cores are uniformly dispersed; the average particle size of the complex coacervation multicore plant essential oil slow-release microcapsule is 95 microns; the loading amount of the plant essential oil exceeds the volume of the cavity used for loading the plant essential oil in the complex coacervation multicore plant essential oil slow-release microcapsule by 65%; the complex coacervation multicore plant essential oil slow-release microcapsule can be added into edible essence, daily chemical essence or cosmetics for use; the complex coacervation multicore plant essential oil slow-release microcapsule has good controlled-release and slow-release functions due to the spherical multicore structure; the complex coacervation multicore plant essential oil slow-release microcapsule not only can be separately used in the edible or daily essence but also can be used in the cosmetics to generate aromas or effects.

Description

technical field [0001] The invention relates to a complex coagulated multi-nuclear plant essential oil slow-release microcapsule with slow release of plant essential oil, its manufacturing method and application. Background technique [0002] Essential oils are volatile aromatic substances extracted from the roots, flowers, stems, leaves, trees, fruits, seeds and other parts of aromatic plants by steam distillation, pressing, or solvent extraction. Relevant studies at home and abroad have shown that many essential oils have antibacterial, calming, health care and other effects, and can be applied to food, daily chemicals, medicine, textiles and other industries. However, due to the characteristics of unsaturated bonds and volatile nature of essential oils, it has the disadvantages of short fragrance retention time and uncontrollable release. , limiting the effect and scope of application of essential oils. [0003] For this reason, we have developed a slow-releasing polyco...
