Description

Plant essential oil microcapsule structure

The present invention relates to a microcapsule; more particularly, to a plant essential oil microcapsule construction utilizing a microcapsule coating technique to extend the fragrance time of a plant essential oil.

Pingtung is in the tropical region with a long average annual sunshine period, which has produced a variety of tropical aromatic plants, such as magnolia, left-handed incense, night scent, wild ginger flower, etc., and it is rich in sunshine. The effect is that it can extract a rich amount of essential oil from plants, and it is estimated that it should have a relatively high industrial development and application value.

The application of plant essential oils in cosmetics is becoming more and more extensive, and the technology is also changing with each passing day. In addition to the extraction technology, plant essential oils are another important development direction in the research and development of formulation process technology.

Plant essential oils are widely used because of their scent, but their aroma and persistence are also different depending on the plant species. Since plant essential oils are oil-soluble substances, if oil-soluble solvents are used (for example: Alcohol) extraction makes plant essential oils easy to volatilize in the air, making the fragrance of plant essential oils not lasting. How to use the microcapsule technology to make the fragrance of plant essential oils spread for a long time is a potential research direction. And can also increase the industrial utilization of plant essential oils.

Based on this, the creators of this case have been engaged in research and development experience in related fields for many years, and have conducted in-depth discussions on the above-mentioned shortcomings, and actively sought solutions based on the above-mentioned needs. After a long period of hard work and many tests, the author finally completed this creation. .

The main purpose of this creation is to increase the persistence of the floral aroma of the plant oil.

The secondary purpose of this creation is to increase the industrial applicability of plant essential oils.

The inner core layer is disposed inside the creation, and the inner core layer is composed of plant essential oil, wherein the plant essential oil is selected from wild ginger flower essential oil, night primrose essential oil, magnolia essential oil or left hand essential oil.

The outer shell layer is coated on the outer layer of the inner core layer, and the outer shell layer is provided with a plurality of connecting holes for connecting the inner core layer to the outside, and the outer shell layer adopts chitosan which has a good affinity with the human body. Made.

The advantages of this creation are further enhanced by the application of the microcapsule coating technology, which enables the creation of the plant essential oil encapsulated in the microcapsules to be released, which can release the essential oil fragrance for a longer period of time than the general essential oil.

For a more detailed understanding of the purpose, function, features and structure of the present invention, the preferred embodiment is described in the accompanying drawings.

First, please refer to FIG. 1 , which is a schematic diagram of the construction of a microcapsule of plant essential oil.

The artificial plant essential oil microcapsule structure 1 comprises an inner core layer 11 and an outer shell layer 12.

The inner core layer 11 is disposed inside the artificial plant essential oil microcapsule structure 1 , and the inner core layer 11 is mainly composed of plant essential oil, and the inner core layer 11 is the main plant flower of the artificial plant oil microcapsule structure 1 . The source of the scent, wherein the plant essential oil of the inner core layer 11 may be selected from wild ginger oil, night primrose oil, magnolia essential oil or left-hand scented oil, and the plant essential oil capable of emitting a significant floral scent as the primary choice, but The aforementioned types of plant essential oils are not intended to limit the scope of this creation.

The outer shell layer 12 is coated on the outer layer of the inner core layer 11. The outer shell layer 12 is provided with a plurality of communicating holes 121 for allowing the inner core layer 11 to communicate with the outside, and the connecting holes 121 on the outer shell layer 12 can be used. The plant essential oil in the inner core layer 11 slowly releases the fragrance into the air to achieve the effect of prolonging the fragrance of the essential oil of the plant. The outer shell layer 12 is made of chitosan, and the chitosan is mainly from the shrimp. The substance made by the crab's shell is a nitrogen-containing polysaccharide biopolymer widely found in nature, and chitosan has a good affinity with the human body, and is in medicine, food, and biology. The use of chitosan can be seen in science and technology.

The artificial plant oil microcapsule structure 1 is mainly prepared by using chitosan having different solubility characteristics in different pH values to prepare the outer shell layer 12 of the plant essential oil microcapsule structure 1 by adjusting the acidity of the solution. The base number is used to control the solubility of chitosan, and the chitosan is made into an outer shell layer 12 capable of coating plant essential oil and having a plurality of communicating pores 121.

The use of the outer layer 12 to cover the inner core layer 11 is that the outer shell layer 12 can greatly limit the surface area of the inner core layer 11 of the plant essential oil in contact with the outside, so that the plant essential oil of the inner core layer 11 is to be released into the air, and only It is slowly dissipated into the air through the communication hole 121 to achieve the effect of prolonging the fragrance of the plant essential oil.

The plant essential oil microcapsule structure 1 can be introduced into medical, cosmetic, biotechnology and other related industries in the future, and the use of the plant essential oil microcapsule structure 1 to develop a characteristic, diverse and safe microcapsule derivative Products can effectively enhance industrial competitiveness and increase the commercial value of products.

In summary, the present invention has the following advantages: 1. By the microcapsule coating technology, the present invention can slowly release the plant essential oil coated inside the microcapsule, thereby releasing the effect of releasing the flower fragrance for a longer period of time. 2. Chitosan has a considerable affinity with the human body, so it can be applied directly to the skin.

Therefore, this creation has excellent progress and practicality in similar products. At the same time, after checking the technical literature on such structures at home and abroad, it has not been found that the same or similar structure exists before the application of this case, so this case It should meet the patent requirements of "creative", "combined with industrial use" and "progressive", and apply in accordance with the law.

It is to be understood that the above-mentioned preferred embodiments of the present invention are intended to be included in the scope of the present invention.
