Embodiment 1～6 and comparative example 1～6

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

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

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

[0026] (2) Cool the 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), adding the filler and the colorant to deionized water, ultrasonically dispersing them evenly, adding them to the mixture B to obtain the mixture C;

[0028] (4) Dissolve the preservative and deionized water and slowly add it to mixture C, stir for 1 hour, vacuumize to remove the foam in the mixture, bake and dry on a cas...

Embodiment 7

[0032] The color foils described in Examples 1 to 6 and Comparative Examples 1 to 6 were tested for stability, and the color foils were added to the jelly and the essence stock solution respectively. Check whether the flakes are dissolved, disintegrated or discolored in the jelly and essence stock solution after 10 days. The test results are shown in Table 2 and Table 3.

Abstract

The invention discloses a cosmetic additive color foil, which comprises the following components in parts by weight: 3-7 parts of hydroxypropyl methylcellulose, 1-5 parts of starch, 0.5-3 parts of filler, and 0.3-1.5 parts of chitosan 0.5-3 parts of plasticizer and 0.05-1 part of glacial acetic acid. The cosmetic additive color foil described in the present invention is a non-water-soluble additive and has the following advantages: 1. Each component complies with the raw materials permitted for cosmetics, and each raw material is reasonably matched and can be evenly fused together; 2. The prepared additive forms a film Good stability, easy to follow-up drying; 3. The color foil has good stability when added to cosmetics, can maintain the shape of the sheet, and the color remains unchanged; 4. When using it, it is slightly affected by external force (such as the force when it is pressed out through the nozzle or the force when smearing). It can be broken into tiny particles invisible to the naked eye; 5. It can enhance the beauty and synergy of 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 have a foil-like appearance and a variety of colors, which endow cosmetics with rich senses, especially in transparent systems such as gels and essences, which can contain multiple functional ingredients. It does not dissolve, disintegrate, or decolorize in cosmetics, and can maintain complete shape and color. It is a commonly used additive in cosmetics. [0003] At present, 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 property, and the dissolution speed is slow when used in cosmetics, and the stability in cosmetics is poor. Contents of the invention [0004] The object of the present invention is to overcome the shortcomings of the prior art and provide a cosmetic a...
