Essential oil microcapsule composition, essential oil microcapsule and preparation method of essential oil microcapsule

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.
