Problems solved by technology

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention aims at the fact that the existing cosmetic products do not have discoloration effects, and some pigments and powders do not match the cosmetic base material, which may easily cause slow color development, unstable color, "floating white" and To solve the technical problem of makeup phenomenon, provide a color-changing capsule that not only has a color-changing effect, but also can match the pigment and powder with the cosmetic base

Embodiment 1

[0015] The diameter of the color-changing capsule in this embodiment is 100-200 μm, and the specific composition formula is as follows:

[0016]

[0017] As shown above, this embodiment uses ethyl cellulose and hydroxypropyl methyl cellulose as composite wall materials; wherein ethyl cellulose is a water-insoluble film-forming agent that can be dissolved in ethanol aqueous solution above 70% concentration It can also be dissolved in some fats such as castor oil. Hydroxypropyl methylcellulose is a water-soluble film-forming material, insoluble in oil, but soluble in 70% ethanol aqueous solution. So choose 70% ethanol aqueous solution as the common solvent of ethyl cellulose and hydroxypropyl methyl cellulose. By adjusting the ratio of ethyl cellulose and hydroxypropyl methyl cellulose, and adding a plasticizer, the capsule wall material of this embodiment can be swelled and softened in the cosmetic matrix without dissolving.

Embodiment 2

[0026] The color-changing capsule (G) is nearly white fine particles, which can be directly dispersed into the water-in-silicone oil emulsion below. The color-changing capsule (G) becomes soft after being soaked in the emulsion base for several days, but the shape remains intact, so that consumers do not feel grainy at all when the capsule structure is destroyed by application. After the color-changing capsule (G) is smeared to destroy the structure, the wrapped toner is released instantly, so that the toner contained in the capsule shell and the core of the capsule works together, and the skin color is quickly mixed on the skin to achieve the effect of discoloration; not only that, but at the same time Also released are titanium dioxide and zinc oxide, which have sunscreen effects, and vitamin E, a nutritional ingredient, which brings the effect of sunscreen and moisturizing the skin. All the toners in this example are hydrophobically treated with polydimethylsiloxane, and ha...

Abstract

A color changing capsule comprises a capsule filling and capsule shell. The capsule filling comprises a material including microcapsules having a first color powder. The capsule shell comprises a material including microcapsules having a second color powder. The microcapsules having the first color powder are collected and made into the capsule filling. The capsule filling is then arranged on a spray plate for coating with the microcapsules having the second color powder to form the capsule shell, thereby obtaining the color changing capsule.

Description

[0001] The invention belongs to the field of microcapsules, in particular to a color-changing capsule. Background technique [0002] As we all know, microcapsule refers to a solid particle product prepared by embedding capsule core materials. As a popular technology in recent years, it has been applied in many fields. For example, it is used to improve the stability of the capsule core itself, to improve the matching degree of the capsule core in the application environment, to cover up the real color and smell of the capsule core, or to achieve timing and fixed-point controlled release, etc. . [0003] Existing cosmetic products, the color that appears on the skin during use is mostly the color of the product’s appearance itself; for example, the color that appears when the existing BB cream product is applied on the skin is the ivory white that appears on its own appearance To light brown, without bringing unexpected discoloration effect to consumers. Not only that, due to...
