Description

TECHNICAL FIELD The present invention relates to a powdery cosmetic, and more particularly, to a powdery cosmetic that has good color development, is excellent in fading and makeup durability, and causes little scattering of powder during use.

Powdery cosmetics, which are widely used as make-up cosmetics such as foundations, face powders, eye colors, etc., are cosmetics containing powder as a main component and appropriately mixed with an aqueous component, an oil component, and the like. Among make-up cosmetics, for example, eyebrow cosmetics for eyebrows are in powder form to be applied with fingers or props, in liquid or oily solid form to be applied with a brush or the like, and in pencil form for direct application to the skin. There are a wide variety of dosage forms on the market, but powder form is often selected when a soft texture is desired. The eyebrows have a great influence on the impression given to people, and the soft focus effect on the eyebrows, which gives a soft impression, and the cosmetic effect, which is easy to blur, are important functions required of eyebrows. In addition, eyebrows are used to apply makeup not only to the skin but also to eyebrows, fibers to which powder is difficult to adhere. Furthermore, good color development is required for eyebrows. A powdery product can impart ease of blurring, but it is difficult to achieve good color development, which is an important quality. Conventionally, powdery eyebrows have realized good color development by blending a large amount of coloring materials, compared to makeup cosmetics such as foundations. In addition, among the coloring materials, a large amount of black pigment is contained in particular from the viewpoint of matching the hue with the original hair color of the eyebrows. Iron oxide is generally used as a black pigment for cosmetics from the viewpoint of safety, and is also widely used in make-up cosmetics.

However, when iron oxide is used for eyebrows, it is necessary to increase the blending amount due to its low blackness. It was necessary to reduce the amount of

Accordingly, the present inventors have devised the use of carbon black, which has a higher coloring power and a higher degree of blackness than iron oxide, to produce powdery cosmetics. However, since carbon black has a small particle size and tends to scatter powder, it is highly scatterable when blended in powdered cosmetics, causing dust, which stains clothes, hands, and faces during use. There are concerns about In addition, there is a problem that the adhesiveness to the skin is poor and the make-up lasts poorly.

Techniques for improving the longevity of powdery cosmetics include a technique using water- and oil-repellent treated powder and solid and/or semi-solid oil agents (Patent Document 1), and an oil component and a swelling organic modified clay mineral. A technique (Patent Document 2) has been proposed. However, with the technique of using water-repellent and oil-repellent treated powder and solid and/or semi-solid oil, although the longevity of makeup is improved, the adhesion is not sufficient. / Or, when the content of the semi-solid oil is increased, the spreadability is impaired, blurring becomes difficult, and the soft focus effect may be impaired. In addition, in the technology using a swelling organically modified clay mineral as a gelling agent, it is necessary to uniformly disperse the swelling organically modified clay mineral in the formulation in order to obtain good adhesion to the skin and moldability. If the dispersion is insufficient, a rough feeling may be felt during use, and furthermore, smooth spreading and blurring are not satisfactory.

Therefore, there has been a demand for a powdery cosmetic that has good color development, suppresses powder scattering during use, and is excellent in blurring and makeup durability.

JP 2010-37213 A JP 2010-235513 A

To provide a powdery cosmetic that gives good color development when applied, is excellent in blurring easiness and makeup durability, and causes less scattering of powder when used.
