Problems solved by technology

[0003] Generally, when coloring toothpaste compositions, water-soluble pigments such as Blue No. 1 are often used from the viewpoint of vividness of the color, etc. In toothpaste preparations, if water-soluble pigments are used, it will cause color migration and bleeding between toothpaste compositions of different colors. In order to prevent these problems, it is known to use water-insoluble pigments, chlorophyll, etc.
[0004] However, when pigments are used, the color lacks vividness, especially when the colored part is a warm color system such as red or yellow.
Furthermore, there is also a problem that the transparency of the colored toothpaste composition is lost, and it is difficult to impart a transparent appearance, and there are difficulties in the aesthetics of the appearance

Embodiment

[0113] [Example, Comparative Example]

[0114] As shown in Tables 1 to 3, after the transparent colored toothpaste composition (I) of the composition shown in Tables 1 to 3 and the opaque white toothpaste composition (II) of the composition shown in Table 4 were manufactured by the usual method, the striped toothpaste In the filling machine, put the colored toothpaste and the white toothpaste into each hopper, and fill them in a tube container (a general tube container for toothpaste without a partition in the container) adjacent to each other in a stripe shape. , to obtain a multicolor toothpaste preparation (test preparation). Colored toothpaste composition (I) / white toothpaste composition (II)=1 / 1 (mass ratio).

[0115] The preparations were tested and evaluated by the following methods, and the results are included in Tables 1-3.

[0116] In addition, the refractive index was measured with an Abbe refractometer (NAR-1T SOLID, manufactured by ATAGO).

Abstract

A kind of multicolor toothpaste preparation, it is characterized in that, colored toothpaste composition (I) and white toothpaste composition (II) are adjacently filled in the container, and described colored toothpaste composition (I) contains (A) from vat dye, One or more water-insoluble pigments selected from oil-soluble dyes and pigments (except, however, aluminum lakes); (B) aluminum lake pigments; (C) polyacrylates and seaweeds selected from (C‑1) one or more selected from acid salts, and the white toothpaste composition (II) contains (D) white particles, (C) one or more selected from (C-2) polyacrylates and alginates.

Description

technical field [0001] The present invention relates to a multi-color toothpaste preparation which is excellent in vividness of color and gives a bright and stable multi-color pattern appearance. Background technique [0002] As a toothpaste formulation, from the viewpoint of aesthetics and attractiveness, multicolored toothpastes that are extruded in a stripe pattern or the like when extruded from a container have been marketed. The combination of colors generally consists of a white paste part of the usual color of the toothpaste composition and a colored paste part other than white. [0003] Generally, when coloring a toothpaste composition, water-soluble pigments such as Blue No. 1 are often used from the viewpoint of vividness of the color, etc. In toothpaste preparations, the use of water-soluble pigments causes color migration and bleeding between toothpaste compositions of different colors. In order to prevent these problems, it is known to use water-insoluble pigme...
