Description

  The present invention relates to a lip cosmetic. In particular, the present invention relates to a cosmetic for lips that is glossy, has a good color (make-up), and an excellent feeling of application (smoothness). The cosmetics for lips here include lipsticks, lip coats, etc., and the dosage forms include sticks, pastes and liquids.

  Conventionally, various methods have been adopted to improve the makeup of lipstick. As an example, there is a method of improving makeup feeling by increasing the blending amount of wax or powder. However, this method has problems such as a lost texture and heavy usability.

  Moreover, the technique which mix | blends a silicone type film | membrane agent (silicone resin etc.) and improves makeup | smoothness by the film formation ability is also known (for example, refer patent documents 1-3). In many cases, the silicone-based film agent is dissolved in a volatile oil and used to form a film by volatilization of the volatile oil. In this case, there is a problem that the gloss over time is extremely worse than immediately after the application of lipstick, or the usability is deteriorated due to the stiffness caused by the resin.

  According to the present invention, there can be obtained a cosmetic for lips which is glossy and has a good color (makeup) and excellent application feeling (smoothness).

  Hereinafter, the present invention will be described in detail.

  The amino-modified silicone as the component (a) used in the present invention is represented by the following formula (I).

  In the above formula (I), m and n are each a positive integer, and m + n is 3,000 to 20,000, preferably 4,000 to 10,000. If m + n is less than 3,000, it is oily and the effect of improving makeup is insufficient. On the other hand, if it exceeds 20,000, it does not dissolve in other cosmetic ingredients such as silicone oil and cannot be blended in cosmetics. N / m is 1/500 to 1 / 10,000, and preferably 1/500 to 1 / 2,000. If it exceeds 1/500, the content of the amino group in the component (a) becomes high, a crosslinking reaction or the like occurs during production, and it is not preferable from the viewpoint of raw material odor. On the other hand, if it is less than 1 / 10,000, the interaction with the skin becomes weak and the makeup lasts worse. (A) A component can use 1 type (s) or 2 or more types.

  The component (b) used in the present invention is an oil component having an IOB of 0.2 to 0.6 in the organic conceptual diagram. Oils with an IOB of 0.2 or less may cause irritation to sensitive skin, and may cause a sticky feel without being refreshed. On the other hand, when the IOB exceeds 0.6, it is difficult to exhibit the function as an oil component.

The organic conceptual diagram was proposed by Satoshi Fujita, and the details are "Pharmaceutical Bulletin", vol.2, 2, pp.163-173 (1954), "Chemical domain" vol.11, 10, pp.719-725 (1957), “Fragrance Journal”, vol.50, pp.79-82 (1981). That is, methane (CH ₄ ) is used as the root of all organic compounds, and all other compounds are regarded as derivatives of methane, and certain numbers are set for the number of carbon atoms, substituents, transformation parts, rings, etc. The score is added to obtain an organic value and an inorganic value, and these values are plotted on a diagram with the organic value on the X axis and the inorganic value on the Y axis. This organic conceptual diagram is also shown in “Organic Conceptual Diagram-Basics and Applications” (by Yoshio Koda, Sankyo Publishing, 1984).

The IOB in the organic conceptual diagram refers to the ratio of the inorganic value (IV) to the organic value (OV) in the organic conceptual diagram, that is, “inorganic value (IV) / organic value (OV)”.
Specific examples of the component (b) include diisostearyl malate (IOB = 0.27), tetra (behenic acid / benzoic acid / ethylhexanoic acid) pentaerythrityl (IOB = 0.35), propylene dicaprylate Glycol (IOB = 0.32), neopentyl glycol dicaprylate (IOB = 0.25), trioctanoin (IOB = 0.35), trimethylolpropane triethylhexanoate (IOB = 0.31), tetraethylhexanoic acid Pentaerythrityl (IOB = 0.35), glyceryl diisostearate (IOB = 0.29), triglyceryl diisostearate (IOB = 0.59), tripropylene glycol dineopentanoate (IOB = 0.52), isodecylbenzoate (IOB = 0.23), 2-ethylhexa Examples include cetyl acid (IOB = 0.52), glyceryl tri-2-ethylhexanoate (IOB = 0.36), di-2-ethylhexyl succinate (IOB = 0.32), and the like. Not a thing. Among them, diisostearyl malate, tetra (behenic acid / benzoic acid / ethylhexanoic acid) pentaerythrityl, glyceryl diisostearate, pentaerythrityl tetraethylhexanoate, trioctanoin, etc., were not sticky on the finished surface. This is preferable from the viewpoint of usability. (B) A component can use 1 type (s) or 2 or more types.

  The component (c) used in the present invention is polybutene. Polybutene is a highly viscous liquid oil at room temperature (25 ° C.) with IOB = 0.

  The cosmetics for lips of the present invention include lipsticks, lip coats, and the like, and include sticks, pastes, and liquids as dosage forms.

On the other hand, if it exceeds 15% by mass, the smooth usability is lost, which is not preferable.

  (B) A component is 1-40 mass%, Preferably it is 5-25 mass%. If the blending amount is less than 1% by mass, the gloss on the usability and the fit of the stretch are not satisfied. On the other hand, if it exceeds 40% by mass, the weight is increased in terms of the usability.

  (C) A component is 1-40 mass%, Preferably it is 5-25 mass%. If the blending amount is less than 1% by mass, sufficient cosmetic durability cannot be obtained, and gloss on the usability and the fit will not be satisfied. On the other hand, if it exceeds 40% by mass, stickiness on the usability will occur. It is not preferable.

  When the present invention is a paste-like or liquid lip cosmetic, the amount of each component is as follows.

  (A) A component is 0.01-15 mass%, Preferably it is 2-5 mass%, Most preferably, it is 0.05-4 mass%. If the blending amount is less than 0.01% by mass, the effect of the moisturizing effect cannot be exhibited. On the other hand, if it exceeds 15% by mass, the smooth usability is lost, which is not preferable.

  (B) A component is 1-60 mass%, Preferably it is 20-50 mass%. If the blending amount is less than 1% by mass, the gloss in terms of usability and the stretchy fit are not satisfied. On the other hand, if it exceeds 60% by mass, stickiness occurs in terms of usability.

  (C) A component is 1-60 mass%, Preferably it is 20-50 mass%. If the blending amount is less than 1% by mass, sufficient cosmetic durability cannot be obtained, and glossiness and fit in usability are not satisfied.
