Description

Stick-type cosmetic

[0001] This invention relates to a bar-shaped cosmetic product.

[0002] Stick-type cosmetics, which are cosmetics filled into stick-shaped containers, are widely used as various types of cosmetics, including lip cosmetics. Recent consumers seem to be seeking stick-type cosmetics that have a melting texture and long-lasting high gloss. However, when realizing high gloss in cosmetics, the amount of hardening agents such as wax is reduced and highly viscous oils are added, which makes the cosmetic itself soft and highly adhesive, resulting in problems with release from filling containers such as capsules, molds, and rubber molds during filling and molding. In that case, the surface of the stick-type cosmetic may be scratched, resulting in an aesthetically unpleasing appearance. Furthermore, if it adheres strongly to the sleeve inside the container, stress is applied when extending and retracting the stick-type cosmetic, causing it to tear or crumble, resulting in poor usability. In addition, cosmetics with a soft and highly adhesive composition tend to lose hardness when exposed to high temperatures such as in summer, causing the stick-type cosmetic to chip or break, resulting in poor usability.

[0003] Therefore, various studies have been conducted to achieve both the high gloss and usability described above. For example, a rod-shaped oily cosmetic has been proposed, characterized by being made by directly filling a container with an oily cosmetic containing specific amounts of wax and hydrogenated polyisobutene (see, for example, Patent Document 1).

[0004] Japanese Patent Publication No. 2010-265255

[0005] However, while the stick-shaped oily cosmetic described in Patent Document 1 was excellent in terms of high gloss of the coated film and release properties from the mold, it did not address the lack of hardness reduction at high temperatures or the inconspicuousness of wrinkles in the coated film.

[0006] In view of the above circumstances, the inventors conducted diligent studies and, as a result, discovered a rod-shaped cosmetic composition that combines wax, oil-soluble polyurethane, a liquid ester oil with a viscosity of less than 3000 mPa·s at 25°C, a liquid ester oil with a viscosity of 3000 mPa·s or more at 25°C, and a hydrocarbon oil that is liquid at 25°C. This composition achieves excellent gloss retention and reduced wrinkles in the coated film, while also exhibiting superior release properties from the mold and no decrease in hardness at high temperatures, thus completing the present invention.

[0007] In other words, the present invention is as described below. [1] A rod-shaped cosmetic composition containing the following components (A) to (E): (A) wax (B) oil-soluble polyurethane (C) liquid ester oil having a viscosity of less than 3000 mPa·s at 25°C (D) liquid ester oil having a viscosity of 3000 mPa·s or more at 25°C (E) a hydrocarbon oil that is liquid at 25°C. [2] The rod-shaped cosmetic composition according to [1], wherein the viscosity of component (C) at 25°C is 10 mPa·s or more and less than 3000 mPa·s. [3] The rod-shaped cosmetic composition according to [1] or [2], wherein the viscosity of component (E) at 25°C is 10000 mPa·s or more and 1500000 mPa·s or less. [4] The rod-shaped cosmetic composition according to [1] or [2], further containing component (F) phenyl-modified silicone. [5] The present invention provides a stick-shaped cosmetic composition according to [1] or [2], further containing (G) a semi-solid ester oil at 25°C (excluding component (A)). [6] The present invention provides a stick-shaped cosmetic composition according to [1] or [2], which is oily. [7] The present invention provides a stick-shaped cosmetic composition according to [1] or [2], which is for use on the lips.

[0008] The present invention provides excellent quality in terms of the persistence of gloss of the coated film, the inconspicuousness of wrinkles in the coated film, release properties from the filling mold, and the absence of hardness reduction at high temperatures.

[0094] (Manufacturing Method) A: Dissolve components (1) to (13) uniformly at 100 to 110°C. B: Add component (22) to A and mix and disperse uniformly at 70 to 80°C. C: Dissolve components (14) to (21) and (23) uniformly at 70 to 80°C. D: Add C to B and emulsify. E: After degassing D, heat and pour into a lipstick mold. After cooling, remove from the mold and load into a container to obtain a stick-type lip balm. The stick-type lip balm of Example 20 provided excellent quality in terms of gloss retention of the applied film, reduced visibility of wrinkles in the applied film, release from the filling mold, and no decrease in hardness at high temperatures.
