Abstract

The invention discloses an essential oil microcapsule composition. The essential oil microcapsule composition comprises, in percent by weight, 30-80% of a core material, 10-45% of a wall material, 2-35% of an emulsifier and water based on the total dry weight of the essential oil microcapsule composition, the core material is essential oil, and based on the total weight of the wall material, the wall material contains, in percent by weight, 70-100% of hyaluronic acid-based components, wherein the hyaluronic acid-based components include hydrolyzed hyaluronic acids with a molecular weight of not more than 10 kDa and / or salts of the hyaluronic acids, hyaluronic acids with a molecular weight of 100 kDa-800 kDa and / or salts of the hyaluronic acids and hyaluronic acids or salt cross-linked polymers of the hyaluronic acids. The invention also discloses an essential oil microcapsule which is prepared from the essential oil microcapsule composition and a preparation method of the essential oilmicrocapsule. The wall material of the microcapsule composition has good stability, can be added to a water phase directly, and has refreshing, smooth and moist skin feelings, the sticky feeling which is generated by single application of essential oil can be reduced greatly, and the characteristic of long-lasting fragrance is achieved.

Description

technical field

[0001] The invention belongs to the technical field of cosmetics, and mainly relates to an essential oil microcapsule composition containing a hyaluronic acid-based component, an essential oil microcapsule and a preparation method thereof. Background technique

[0002] Natural plant essential oils have very low solubility in the water phase system, are unstable in nature, are volatile, and are easily oxidized and decomposed after being heated, and the skin has a sticky feeling after use. In order to make it available in the formulation of daily chemical products, It is necessary to improve the water solubility and stability of essential oils. The preparation of essential oils into microcapsules is a relatively common stabilization process.

[0003] Chinese patent application CN108210569A discloses a tea tree oil microcapsule and its granules, the parts by weight of which are 1 part of tea tree oil, 0.5 to 1 part of phospholipid, 0.05 to 0.2 part of oil-solub...

Examples

preparation example Construction

[0086] The present invention also provides a method for preparing essential oil microcapsules from the essential oil microcapsule composition, wherein the essential oil microcapsule composition comprises a core material, a wall material, an emulsifier and water, wherein the weight of the core material accounts for the 30-80% of the total dry weight of the essential oil microcapsule composition, the weight of the wall material accounts for 10-45% of the total dry weight of the essential oil microcapsule composition, and the weight of the emulsifier accounts for the total dry weight of the essential oil microcapsule composition. 2-35% of dry weight, the core material is essential oil, based on the total weight of the wall material, the wall material contains 70-100% by weight of hyaluronic acid-based components, and the hyaluronic acid-based components It comprises: hydrolyzed hyaluronic acid and / or its salt with a molecular weight not greater than 10kDa, hyaluronic acid and / or its...

Embodiment 1

[0111] The total weight of the essential oil microcapsule composition in this embodiment is 100g, which includes: 4g hydrolyzed hyaluronic acid and its salt (molecular weight≤10kDa), 0.1g hyaluronic acid and its salt (100kDa≤molecular weight≤800kDa), 0.2 g hyaluronic acid or its salt cross-linked polymer, 0.1 g maltodextrin, 0.05 g starch, 10 g rose essential oil, 5 g hydrogenated lecithin, and the balance is deionized water.

[0112] The preparation method of the essential oil microcapsules of the present embodiment is as follows:

[0113] (1) Weigh each component of the above-mentioned content of the wall material and add them to the beaker in turn;

[0114] (2) Add an appropriate amount of deionized water to the beaker, heat and stir, so that the components of the above-mentioned wall material are completely dissolved, stop heating, and obtain the first mixed solution;

[0115] (3) adding the hydrogenated lecithin of the above content to the first mixed solution to form a ...

Embodiment 2

[0121] The difference between the essential oil microcapsule composition in this example and Example 1 is that its total weight is 100g, which contains: 2g of hydrolyzed hyaluronic acid and its salt (molecular weight≤10kDa), 0.2g of hyaluronic acid and its salt (100kDa≤molecular weight≤800kDa), 0.1g hyaluronic acid or its salt cross-linked polymer, 0.2g maltodextrin, 0.05g starch, 3g lavender essential oil, 3g tea tree essential oil, 3g verbena essential oil, 3g chamomile essential oil, 2g hydrogenated lecithin, and the balance is deionized water.

[0122] The preparation method of essential oil microcapsules is the same as in Example 1.
