Description

  The present invention relates to a rod-shaped cosmetic.

  Rod-like cosmetics such as eyeliner, eyebrow, lip liner, concealer pencil, and eye shadow pencil are used in the form of pencil type or pencil type used by drawing out the core, uniformity of coating film, good elongation, ease of drawing In addition to suppressing the secondary adhesion, usability such as excellent in cosmetic retention effect is required, and moldability and mechanical strength at the time of production are also desired for the performance.

  The rod-like cosmetic comprises an oily component containing a wax and a liquid oil, and a powder such as a pigment as a skeleton. Although it is necessary to satisfy moldability and usability by adjusting the mixing ratio of the wax and the liquid oil, it is very difficult to simultaneously satisfy the moldability and usability required for the product. This is because when the wax component is blended in a large amount to obtain moldability, the elongation and the cosmetic retention effect tend to be inferior, while when the wax component is reduced to obtain good usability, the moldability and It is because mechanical strength tends to be inferior.

  Heretofore, various devices have been made to achieve both moldability and usability in a rod-like cosmetic. For example, in order to obtain sufficient moldability with a small amount of wax, it is known to combine a plurality of waxes, in particular, high melting point waxes. (Patent documents 1 and 2). In addition, in order to enhance usability and cosmetic retention effect, methods using volatile oil and organic silicone resin are also considered (Patent Documents 3 and 4).

JP 2002-348204 A JP 2008-133205 A JP 10-72315 A JP 2012-77049 A

  However, in the techniques described in Patent Documents 1 and 2 in which a plurality of waxes are combined, in a thin rod-shaped cosmetic having a core diameter such as an eyeliner, mechanical strengths such as moldability, breaking strength and falling strength are sufficiently satisfied. I can not do it. Further, the techniques described in Patent Documents 3 and 4 improve both the strength such as moldability and the usability such as the cosmetic retention effect, but because the blending amount of the wax is large, the impression of drawing is not smooth and hard It becomes. In particular, the skin around the eyes, such as eyelids, is softer than other parts, so it is desirable to be able to draw with light force. Even if it is a soft core formulation that contains a low-hardness wax in an amount sufficient to maintain the shape of the core, it will stretch because it will be applied while the core collapses when drawn on the skin Poor, the amount of coating increases, quick-drying is impaired, etc., it is not yet sufficient to achieve high levels of usability such as ease of drawing and makeup retention effect and high strength such as moldability, and further improvement There is a need for

  The present invention has been made in view of the above circumstances, and it has excellent moldability and mechanical strength even with a small amount of wax compounded, can be drawn smoothly with light force, has coloring power, and after application It is an object of the present invention to provide a stick-shaped cosmetic which has good adhesion and is excellent in cosmetic retention effect without secondary adhesion.

  In order to solve the above problems, as a result of intensive investigations, the present inventors have determined that, among various polyethylene waxes used in rod-like cosmetics, those having an average molecular weight of 600 or more and carnauba wax are specified. It has been found that the wax composition mixed in proportions gives excellent hardness as a solidifying agent for rodlike cosmetics. And by blending a specific amount of this wax composition with a specific liquid component or powder component, it has excellent moldability and mechanical strength even with a small amount of wax blended, and can be drawn smoothly with a lighter force than before. After application, the adhesive property is good, the secondary adhesion resistance is excellent, and even if the coating film is thin, it has coloring power, so it is found that the consumption of the cosmetic is small and economically excellent, and the present invention is completed. It came to

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

  In the present specification, the "wax composition" refers to a composition comprising the component (A), the component (B), and a wax other than the component (A) and the component (B).

  In the present specification, the content of the film forming agent in the rod-like cosmetic refers to a value in terms of solid content of the film forming agent.

  As used herein, "volatile silicone oil" means a silicone oil having a boiling point of 250 ° C. or less at 1 atm.

  The polyethylene wax of component (A) is one generally used in cosmetics. The average molecular weight is 600 or more in terms of maintaining moldability and mechanical strength. When the average molecular weight is less than 600, the solidification power of the oil is low and the moldability and mechanical strength are poor, and even when it is blended when an amount capable of maintaining sufficient moldability is blended, it is applied while being broken Because it becomes a state, it is heavy in drawing comfort, and it becomes inferior to quick drying because the coating film becomes thick. When the average molecular weight is 750 or more, although the moldability and mechanical strength are sufficient, the melting point becomes very high, and the handling in manufacturing of the rod-like cosmetic becomes difficult. Commercially available products include PERFORMALENE 655, PERFORMALENE 725 (manufactured by New Phase Technology) and the like.

If the content is less than 4% by mass, it does not function as a solidifying agent, which may cause problems in moldability and mechanical strength of the product.

  The content of the component (A) in the wax composition is preferably 50 to 95% by mass, and more preferably 60 to 90% by mass. When a wax composition containing the component (A) in this range is prepared, the hardness of the rod-like cosmetic shows a very high value, and the above-mentioned wax composition exhibits extremely excellent effects as a solidifying agent.

  In addition, the rod-shaped cosmetics which concern on this embodiment can contain waxes other than component (A) and (B) in the range which does not impair the effect of this invention.

  Comparative Example 8 was prepared in the same manner as Comparative Example 1 except that the polyethylene wax of Comparative Example 1 was replaced with carnauba wax, and as a result, the carnauba wax did not dissolve uniformly. In addition, Comparative Example 9 in which the polyethylene wax of Example 1 was replaced with Fischer-Tropsch wax: Sanwax 171-P (manufactured by Sanyo Chemical Industries, Ltd.), and Comparative Example 10 in which microcrystalline wax: Multiwax (manufactured by SONNEBORN) was substituted. Were prepared in the same manner as Example 1, and as a result, the wax composition did not dissolve uniformly.
