Description

Water-based cosmetics

The present invention relates to a water-based cosmetic. More specifically, the present invention relates to an aqueous cosmetic material capable of suppressing precipitation and aggregation of powder and having excellent dispersion stability, although a large amount of powder components are blended in an aqueous cosmetic material prepared with polyvinyl alcohol.

In recent years, in addition to the functions required to adjust the condition of the skin or beautify the skin, the novelty and unique characteristics of the appearance when applied to the skin have also become important elements of sales value. For example, it is also a fact that it is possible to sell dressing cosmetics that have animal patterns and the like printed on the cotton of the mask, and promote the purchase of these products through the response on SNS (Social Network Services, Social Network Services).

In addition to using printed cotton for masks, as a means of satisfying consumer preferences as described above, consider a cosmetic that can be colored with a colorant and applied to a desired location. In order to realize such a cosmetic, a large amount of colorant must be formulated to be colored into an unprecedented novel color. From the viewpoint of safety to the environment and the human body, it is preferable to use a pigment as a colorant. However, if a large amount of a pigment is blended in a cosmetic, precipitation and aggregation occur over time.

Conventionally, in order to suppress the precipitation of pigments formulated in cosmetics, it has been proposed to mix clay minerals with specific thickeners (Patent Document 1 and Patent Document 2).

On the other hand, polyvinyl alcohol is used as a component that is used in a large amount for basic cosmetics, cosmetic cosmetics, and the like for the purpose of imparting firmness to the skin, forming a film, and the like. Among these, in the case of a tear-off type dressing which has a cleaning effect of removing dirt adhered to the skin or aged horny layer, from the viewpoint of quick drying or ease of peeling after drying, it is preferable to use poly Vinyl alcohol is the main component.

However, as also described in Patent Document 3, in the preparation of polyvinyl alcohol-containing cosmetics, there is a problem that the pH value of the cosmetics changes due to the hydrolysis of acetic acid residues contained in the polyvinyl alcohol over time. , Agglomeration or precipitation of the formulated powder occurs, which impairs the stability of the composition over time. Therefore, in order to stably mix a large amount of powder in a cosmetic material formulated with polyvinyl alcohol, further improvement is necessary.

[Example]

Hereinafter, the present invention will be described in more detail with specific examples, but the present invention is not limited to the following examples. It should be noted that the blending amounts in the following examples and the like represent mass% unless otherwise specified.

Prior to the examples, the effect of different HLB surfactants on the dispersibility of the powder was studied. Specifically, the components shown in Table 1 below were mixed and dissolved to prepare samples 1 to 7 containing surfactants having different HLBs, and the state of precipitation of the powder components over time was visually observed.

[Table 1]

The higher the HLB of the formulated surfactant, the slower the precipitation speed of the powder. Therefore, it can be seen that the higher the HLB of the formulated surfactant, the more effectively the precipitation of powder components is suppressed.

Next, a sample having the composition shown in Table 2 below was prepared, and (1) measurement of viscosity and (2) stability evaluation (precipitation and aggregation of powder components, and layer separation of solution) were evaluated. The evaluation was performed as described below.

(1) Measurement of viscosity After the prepared sample was left to stand at 30 ° C for 1 day, the viscosity (mPa · s) was measured with a BL-type viscometer (rotor No. 6, 10 rotations).

(2) Evaluation of stability After the prepared sample was left to stand at 70 ° C for 3 days, the appearance was visually observed to evaluate the presence or absence of precipitation and aggregation of powder components and the phase separation of the entire sample. .

Examples 1 to 4 and Comparative Examples 1 to 2

[Table 2]

As shown in the above table, when only one kind of polysaccharide thickener was prepared (Comparative Examples 1 and 2), precipitation and aggregation of powder components were observed with time, and separation of the solution was observed. It can also be seen from the comparison between Example 2 and Comparative Example 2 that even when the blending amount of polyvinyl alcohol is the same, the dispersion stability of the powder can be obtained by blending two or more polysaccharide thickeners and Cosmetics with moderate viscosity. In addition, the spreading and diffusing properties of the cosmetic materials of Examples 1 to 4 on the skin were also good. In addition, the cosmetic materials of Examples 2 to 4 prepared by combining polyvinyl alcohols having different viscosities have better powder dispersibility than the cosmetic material of Example 1 in which only a single viscosity of polyvinyl alcohol is prepared.

It is investigated whether the cosmetic of the present invention can be obtained when other aqueous phase tackifiers are used instead of polysaccharide tackifiers and vinyl-based water-soluble tackifiers in the cosmetic of the present invention.

[table 3]

As shown in Table 3, in the cosmetic of the present invention, when other water-phase tackifiers are used instead of polysaccharide tackifiers and vinyl-based water-soluble tackifiers, precipitation and aggregation of powders and solution are observed. Separation. Therefore, in the polyvinyl alcohol-based cosmetic prepared with a large amount of powder according to the present invention, the precipitation and aggregation of the powder cannot be suppressed by the clay mineral widely used to adjust the viscosity of the cosmetic.
