Technical Field
The present invention relates to a powdery composition for make-up for keratin materials (for example the skin) comprising a flop pigment and a white pigment, and to a cosmetic process using this composition.
Background
Cosmetic powder compositions for keratin materials are used as make-up cosmetics such as foundation powders (foundation powders) and make-up powders. These compositions are used to provide an attractive appearance to keratin materials. Thus, for cosmetic powder compositions to act as make-up cosmetics, aesthetic effects on keratin materials (preferably skin, especially facial skin) such as providing natural finish (natural finish) effects, stereoscopic appearance effects and good hiding are very important. In order to impart such aesthetic effects to cosmetic powder compositions, it has been proposed to use effect pigments (goniochromatic pigment) in the compositions.
For example, JP-A-H11-322541 discloses a cosmetic composition comprising: a cosmetically acceptable medium; at least one first colorant; and at least one second colorant; wherein the first colorant is a flop colorant capable of producing different colors depending on the angle of incidence of light and the angle of observation, the flop colorant is a multilayer interference structure, and the second colorant is a single color colorant producing one of the colors of the flop colorant.
In addition, US-B-5,008,143 discloses a flop pigment exhibiting a polychromatic effect, consisting essentially of a transparent body, an interference pigment and an absorbing colorant, wherein the absorbing colorant has a color different from the reflected color of the interference pigment or its complement, and wherein the interference pigment and the absorbing colorant have color intensities of the same order of magnitude.
However, there is still a need for cosmetic powder products with improved cosmetic effect. In particular, there is a need for cosmetic powder products that provide aesthetic effects to keratin materials (preferably skin, especially facial skin), such as providing natural finish, a three-dimensional appearance, and good coverage.

Hereinafter, the composition according to the present invention will be described in detail.
[ composition ]
The powdery composition according to the invention comprises (a) at least one effect pigment capable of producing different colors depending on the angle of incidence of light and the angle of observation, wherein the effect pigment comprises light-transmitting platelets, titanium dioxide and a colorant and exhibits an interference color selected from pink, red, orange, yellow and gold in an amount of 10 to 50% by weight relative to the total weight of the composition; and (b) at least one white pigment in an amount of 0.5 to 15% by weight relative to the total weight of the composition.
(effect pigment)
The composition according to the invention comprises (a) at least one effect pigment. Two or more (a) effect pigments may be used in combination. Thus, a single type of effect pigment or a combination of different types of effect pigments may be used.
The term "pigment" is understood herein to mean white or colored inorganic or organic particles in a medium insoluble in the composition.
The term "flop pigment" is understood herein to mean a pigment that exhibits flop properties that produce different colors depending on the angle of incidence of the light and the angle of observation. Thus, (a) effect pigments are capable of producing different colors depending on the angle of incidence of light and the angle of observation.
Effect pigments typically have an interference multilayer structure consisting of light transmissive platelets and a coating of interference pigment on the platelets. The multiple layers may make it possible to allow variations in color, hue and brightness to be produced by interference of light that is diffracted and diffused differently from layer to layer. In addition, the effect pigment may include at least one absorbing colorant in the coating. In this case, the effect pigments may exhibit two different colors: an "absorption color" that can result from the absorption of the colorant and a "reflected color" that can result from reflection from the interference pigment, depending on the angle of observation. At normal viewing angles, the reflected color of the interference pigment is seen. At the diffusion or glancing angle, the reflected color of the interference pigment is no longer observed, and the absorption color is now seen. Therefore, by changing the angle of observation from the normal angle to the glancing angle, the reflected color of the color by interference (pigment generation) becomes the absorption color by the absorption pigment (generation).
The effect pigment of (a) of the present invention comprises light transmitting platelets, titanium dioxide as an interference pigment and a colorant as an absorption pigment.
The material of the light-transmitting tab is not limited as long as it is light-transmitting.

The additive may be selected from anionic, cationic, nonionic or amphoteric polymers; natural thickeners or synthetic thickeners; lubricants or dispersants, such as sorbitan fatty acid esters, for example sorbitan sesquioleate; a gelling agent; natural extracts from animals or plants; a wax; a cosmetically acceptable hydrophobic organic solvent; preservatives, such as sodium dehydroacetate, phenoxyethanol, and chlorpheniramine; co-preservatives (co-preservatives) such as decanediol, ethylhexyl glycerol and octanediol; a germicide; vitamins or provitamins; a perfume; stabilizers, such as magnesium sulfate; and mixtures thereof.
The amount of additives included in the composition according to the present invention is not limited, but may be 0.01 to 30 wt% with respect to the total weight of the composition according to the present invention.
The composition of the present invention is a powdery cosmetic composition for keratin materials such as skin, for example, the skin of the face, neck and body, especially the facial skin, and more preferably a cosmetic make-up (cosmetic make-up) composition for the skin. The composition according to the invention may be provided in the form of a pressed powder or compact, blush or powder.
The composition according to the invention can provide keratin materials, in particular the face, with an improved natural and three-dimensional appearance, while maintaining good coverage to cover skin imperfections such as blemishes, wrinkles and (hair) holes. Thus, the composition according to the invention may provide a smaller and more distinct (defined) natural appearance of facial features.
It should be noted that the use of the composition according to the invention may create a stereoscopic appearance or volume effect on the face and thus does not require the use of different types of powder cosmetics, which are required by the rules of care to create a stereoscopic appearance. In addition, the use of the present invention does not require a high level of skill on the consumer to create a stereoscopic appearance on their face. Thus, the composition according to the invention is very suitable for use as a make-up powder, such as foundation powder, make-up powder or face powder; a body color cosmetic product; blush; and eye shadows, especially foundation powders and make-up powders.
The composition according to the invention is preferably anhydrous or contains less than 3% by weight of water and preferably less than 1% by weight of water relative to the total weight of the composition. The term "anhydrous" particularly means that water is preferably not deliberately added to the composition and more preferably is not present in the composition, but may be present in trace amounts in the various ingredients used in the composition.
[ beauty treatment method ]
The invention also relates to a cosmetic method comprising the step of applying the composition according to the invention to keratin materials, such as the skin, preferably facial skin. The composition may be picked up by rubbing off the powder with an applicator (e.g., a sponge, puff or brush). The composition may then be moved from the applicator to the skin by contacting the applicator against the skin.
The composition used according to the invention is preferably intended for use as leave-on cosmetic composition. The term "leave-on" refers to a composition that is not intended to be washed off or removed immediately after administration.
Because the compositions according to the present invention can provide improved natural and stereoscopic appearance to keratin materials (especially the face) while maintaining good hiding efficacy, the cosmetic methods according to the present invention can provide the keratin materials (especially the face) with a natural appearance as well as an attractive appearance of smaller and clearer features.
The invention also relates to the use of a combination of (a) a flop pigment and (b) a white pigment as a make-up active in cosmetic powder compositions (e.g. foundation powder, make-up powder or face powder; body make-up products; blush; and eye shadows, especially foundation powder and make-up powder).
Examples
The present invention will be described in more detail by means of examples. However, these examples should not be construed as limiting the scope of the invention.
< example 1 and comparative examples 1 to 5>
[ composition ]
The compositions according to example 1 and comparative examples 1 to 5 were prepared by mixing the ingredients listed in table 1, and then pressed with a press to obtain a pressed powder foundation. The compositions are shown in table 1. In table 1, all components are based on "wt%" (based on active raw materials).
[ evaluation ]
The compositions according to example 1 and comparative examples 1 to 5 were evaluated by 7 monitors with respect to three key properties of three-dimensional appearance effect, natural finishing and hiding efficacy. Each of the compositions according to example 1 and comparative examples 1 to 5 was applied on the monitor's face by the monitor himself, and the monitor evaluated whether they could perceive the stereoscopic effect after application, sufficient coverage, and natural finish. Table 1 shows how many people perceive each effect.
+++:6-7 people perceive effect
++:4-5 people perceive effect
+:2-3 people perceive effect
-:0-1 person perceives effect
TABLE 1
-effect pigments (a): product name: BASF (basic Acrylonitrile butadiene styrene)YR 422C; the pigment contained 52.5 wt% mica, 43.5 wt% titanium dioxide and 4 wt% Fe 2 O 3 . The interference color is red.
-effect pigments (b): product name:the pigment contained 52.5 wt% silica, 32.5 wt% aluminum powder and 15 wt% iron oxide. The interference color is red.
-effect pigments (c): product name: reliefBeige; the pigment comprises 75% by weight of mica, 15% by weight of titanium dioxide, 5% by weight of iron oxide and 5% by weight of silicon dioxide. The interference color is silver.
-effect pigments (d): product name:pink; the pigment contained 83 wt% mica, 16 wt% titanium dioxide and 1 wt% iron oxide. The interference color is silver.
As can be seen from the evaluation results in table 1, the composition according to example 1, which includes a combination of the effect pigment of the present invention and the white pigment in specific amounts, exhibits excellent stereoscopic appearance effect, natural finishing, and sufficient hiding efficacy.
On the other hand, the compositions according to comparative examples 1 to 3, which did not contain the effect pigments of the present invention, did not provide sufficient natural finishing or stereoscopic appearance effect. The composition according to comparative example 4 comprising (but including in a small amount) the effect pigment of the present invention does not provide sufficient stereoscopic appearance effect and hiding efficacy. The composition according to comparative example 5, which does not include a white pigment, does not provide a hiding power.
Example 2 ]
The composition according to example 2 was prepared by mixing the ingredients listed in table 2 and subsequently pressed with a press to obtain a foundation of a pressed powder. The compositions are shown in table 2. In table 2, all components are based on "wt%" (based on active raw materials).
TABLE 2
-effect pigments (a): product name: BASF (basic Acrylonitrile butadiene styrene)YR 422C; the pigment contained 52.5 wt% mica, 43.5 wt% titanium dioxide and 4 wt% Fe 2 O 3 . The interference color is red.
It was also confirmed that the composition according to example 2 can provide three key properties of a remarkable stereoscopic appearance effect, natural finish and good hiding efficacy in the monitor test.
Thus, it can be concluded that: the powdery composition according to the present invention is highly preferably used as a makeup powder, such as foundation powder, make-up powder or face powder; a body color cosmetic product; blush; and eye shadows, especially foundation powders and make-up powders.
