Problems solved by technology

[0004] In addition, capsules that can be applied to various methods have been proposed, but these existing methods do not contribute to the stability, color, and feeling of use of raw materials desired by consumers when applied to actual cosmetic dosage forms, so there is a limit to the application of cosmetics sex

[0035] (1) Preparation of single-layer capsule

[0036] The single-layer capsule of the present invention is prepared by mixing water insoluble substances, stabilizing agents and hollow silicon dioxide in the first solvent, filling it homogeneously and then dehydrating it. The single layer prepared in this way is a hollow silica with excellent filling ability for thermal stability and oil-soluble substances, and it can have thermal characteristics and internal chemical stability by filling and encapsulating poorly water-soluble substances containing stabilizers.

[0037] As the poorly water-soluble substance, carotenoids, ceramide liquid crystals, oil-soluble vitamins, oil-soluble extracts, and oil-soluble pigments are preferably used, which have the property of not dissolving in water but dissolving in oil. At this time, the carotenoid is any one selected from astaxanthin, α-carotene, β-carotene, zeaxanthin, lutein, lycopene, capsanthin, β-cryptoxanthin, and canthaxanthin. m...

Abstract

The task of the present invention is to provide a capsule and a manufacturing method therefor, the capsule having a triple-layer structure by using a hollow silica capsule comprising a poorly water-soluble substance and a stabilizer, a hydrogel consisting of a polymer blend, and a polymer having suitable hydrophobicity. The main feature of the present invention consists of: a single-layer capsule consisting of a poorly water-soluble substance, a stabilizer and a hollow silica; a double-layer capsule in a form such that the outside of the single-layer capsule is surrounded by a hydrogel polymer blend; and a triple-layer capsule in a form such that the outside of the double-layer capsule is surrounded by a polymer having hydrophobicity.

Description

technical field [0001] The present invention relates to a stabilized three-layer capsule and its preparation method, which uses hollow silicon dioxide, polymer hydrogel and polymer with hydrophobicity in order to protect poorly water-soluble substances from external harmful environments. Background technique [0002] The water-insoluble substances used in cosmetics are representative, such as carotenoids, ceramide liquid crystals, oil-soluble vitamins, oil-soluble extracts, and pigments. The unstable nature and color of the substance or the disadvantages of reduced efficacy, color, and feeling of use due to greasy feeling and due to the raw materials contained in the cosmetic formulation, especially oxygen, water, oil, surfactant or due to The heat generated during the preparation of the dosage form further aggravates the problem, so it is not easy to use. In order to solve these problems, methods such as liposome formation, emulsification, and encapsulation have been used ...
