Cosmetic additive color foil and preparation method thereof

Abstract

The invention discloses cosmetic additive color foil. The color foil comprises components in parts by weight as follows: 3-7 parts of hydroxypropyl methyl cellulose, 1-5 parts of starch, 0.5-3 parts of filler, 0.3-1.5 parts of chitosan, 0.5-3 parts of a plasticizer and 0.05-1 part of glacial acetic acid. The cosmetic additive color foil is a water-insoluble additive and has the following advantages: 1, all the components conform to cosmetic allowable raw materials, and all the raw materials are matched reasonably and can be uniformly blended; 2, the prepared additive is good in film forming property and prone to following drying; 3, the color foil has good stability, can keep piece type and has unchanged color after added to cosmetics; 4, the color foil can be crushed into tiny particles invisible by naked eyes after slightly receiving an external force (such as spray head press-out force and smearing force) during use; and 5, the color foil has beautifying and synergistic effects on cosmetics. The invention also provides a preparation method of the cosmetic additive color foil.

Description

Technical field

[0001] The invention relates to a cosmetic additive, in particular to a cosmetic additive color foil and a preparation method thereof. Background technique

[0002] Cosmetic additives color foil flake appearance, a variety of colors, giving cosmetics rich senses, especially in transparent systems such as gel and essence, etc. can contain a variety of functional ingredients. It does not dissolve, disintegrate, or discolor in cosmetics, and can maintain a complete shape and color. It is a commonly used additive in cosmetics.

[0003] At present, the domestic cosmetic additive color foil mainly relies on imports, and there is a gap in domestic technology. The existing color foils have poor film-forming properties, have a slow dissolution rate when used in cosmetics, and have poor stability in cosmetics. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a cosmetic additive color foil and ...

Examples

Embodiment 1～6 and comparative example 1～6

[0023] Examples 1 to 6 and Comparative Examples 1 to 6 are examples of the colored foils of the present invention. The raw material formulas of the colored foils of Examples 1 to 6 are shown in Table 1.

[0024] The preparation method of colored foil described in Examples 1 to 6 and Comparative Examples 1 to 6 includes the following steps:

[0025] (1) Add starch and 70% deionized water, gelatinize at 80°C, add hydroxypropyl methylcellulose and chitosan and mix well to obtain mixture A;

[0026] (2). Reduce mixture A to room temperature, add glacial acetic acid, stir for 3 to 5 minutes, add glycerin, and stir evenly to obtain mixture B;

[0027] (3) Add the filler and colorant to deionized water, ultrasonically disperse them uniformly, and add them to mixture B to obtain mixture C;

[0028] (4) Dissolve the preservative and deionized water and slowly add it to the mixture C, stir for 1 hour, vacuum to remove the foam in the mixture, and bake and dry on the casting machine, the drying te...

[0032] The color foils described in Examples 1 to 6 and Comparative Examples 1 to 6 were tested for stability performance, and the color foils were added to the gel and essence liquid, respectively, at 0 days, 30 days, 60 days, 90 days, 120 days and 150 days. After days, check whether the flakes are dissolved, disintegrated or discolored in the gel and essence stock solution. The test results are shown in Table 2 and Table 3.
