Description

TECHNICAL FIELD The present invention relates to a stick-shaped cosmetic.

Stick-shaped cosmetics such as eyeliners, eyebrows, lipliners, concealer pencils, eyeshadow pencils, etc. are used in the form of pencils or pencils that are used by pulling out the lead, and are characterized by uniform coating, good spreadability, and ease of application. In addition to the usability such as suppression of secondary adhesion and excellent makeup retention effect, moldability and mechanical strength at the time of production are also desired for performance.

A stick-shaped cosmetic is composed of an oily component containing wax and liquid oil, and a powder such as a pigment as a skeleton. Moldability and usability must be satisfied by adjusting the mixing ratio of the wax and the liquid oil, but it is very difficult to simultaneously satisfy the moldability and usability required for the product. This is because if a large amount of the wax component is blended in order to obtain moldability, there is a tendency for the elongation and makeup retention effect to deteriorate. This is because the mechanical strength tends to be inferior.

Conventionally, various ideas have been made in order to achieve both moldability and usability in bar-shaped cosmetics. For example, in order to obtain sufficient moldability with a small amount of wax, a method of combining a plurality of waxes, especially waxes with high melting points, is known. (Patent Documents 1 and 2). Moreover, methods using volatile oils and organic silicone resins have also been considered in order to enhance usability and makeup-retaining effects (Patent Documents 3 and 4).

However, the techniques described in Patent Documents 1 and 2 in which a plurality of waxes are combined sufficiently satisfy mechanical strength such as moldability, bending strength, and drop strength in rod-shaped cosmetics with a thin core diameter such as eyeliner. I can't. In addition, the techniques described in Patent Documents 3 and 4 improve both strength such as moldability and usability such as makeup retention effect, but because the amount of wax blended is large, the feeling of drawing is not smooth and gives the impression of being hard. becomes. In particular, the skin around the eyes, such as the eyelids, is softer than other parts, so it is desirable to be able to draw with a light force. Even with a soft core formulation that contains an amount of wax with low hardness that is sufficient to maintain the shape of the core, the core will collapse when applied to the skin, so it will not stretch. Unfortunately, the amount of coating film increases and the quick-drying property is impaired, so it is still not enough to achieve both usability such as ease of drawing and makeup retention effect and strength such as moldability at a high level. need.

The present invention has been made in view of the above circumstances, and has excellent moldability and mechanical strength even when the amount of wax blended is small. To provide a stick-shaped cosmetic which has good adhesion and excellent makeup-retaining effect without secondary adhesion.

In order to solve the above problems, the present inventors conducted extensive studies and found that among various polyethylene waxes used in bar-shaped cosmetics, those having an average molecular weight of 600 or more and carnauba wax were selected as specific waxes. It was found that the wax composition mixed in the ratio gives excellent hardness as a solidifying agent for stick-shaped cosmetics. By blending a specific amount of this wax composition with a specific liquid component and a powder component, it has excellent moldability and mechanical strength even with a small amount of wax, and can be drawn smoothly with less force than before. After application, it has good adhesion, excellent secondary adhesion resistance, and has coloring power even if the coating film is thin. reached.

That is, the present invention is a stick-shaped cosmetic containing a wax composition, which contains the following components (A) to (E), and the content of the wax composition is 4 to 13% by mass with respect to the total amount of the cosmetic. A stick-shaped cosmetic characterized by containing 50 to 95% by mass of component (A) in a wax composition.

It becomes possible to provide cosmetics.

Preferred embodiments of the stick-shaped cosmetic of the present invention are described in detail below.

The stick-shaped cosmetic of the present invention comprises (A) a polyethylene wax having an average molecular weight of 600 or more (hereinafter sometimes referred to as component (A)) and (B) a wax composition containing carnauba wax (hereinafter sometimes referred to as component (B) ), (C) a film-forming agent (hereinafter sometimes referred to as component (C)), (D) a volatile silicone oil agent (hereinafter sometimes referred to as component (D)), and (E) powder (hereinafter sometimes referred to as A stick-shaped cosmetic containing a component (E)), which contains 4 to 13% by mass of the wax composition relative to the total amount of the stick-shaped cosmetic, and 50 to 50% of the component (A) in the wax composition. It contains 95% by mass.

As used herein, the term "wax composition" refers to a composition comprising component (A), component (B), and a wax other than component (A) and component (B).

In the present specification, the content of the film-forming agent in the stick-shaped cosmetic refers to the value of the film-forming agent in terms of solid content.

Component (A) polyethylene wax is commonly used in cosmetics. Its average molecular weight is 600 or more from the viewpoint of maintaining moldability and mechanical strength. If the average molecular weight is less than 600, the solidification power of the oil will be low, resulting in poor moldability and mechanical strength. It is difficult to draw because it is in a state, and the coating film is thick, so it is inferior to quick drying. When the average molecular weight is 750 or more, the moldability and mechanical strength are sufficient, but the melting point becomes very high, making it difficult to handle in the production of the cosmetic stick. Commercially available products include PERFORMALENE655 and PERFORMALENE725 (manufactured by New Phase Technology). Component (A) may be used alone or in combination of two or more.
