Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skin cosmetic which has a refreshing effect and a long lasting effect.

[0002]

2. Description of the Related Art Generally, in order to obtain a refreshing feeling of cosmetics,
Cooling agents such as camphor, menthol, eucalyptus oil, and mint such as spearmint and peppermint are blended. However, although these can provide a refreshing sensation temporarily, the effect quickly diminishes. That is, it was difficult for these cooling agents to control the cooling effect and maintain the cooling sensation for a long time. Thus, a menthol derivative having a delayed effect on the refreshing sensation has been found (JP-A-60-25908). It has also been found that the addition of glyceryl ether can maintain the refreshing effect (JP-A-63-208505).

[0003]

This menthol derivative has a slow effect on the refreshing sensation, but the refreshing sensation is poor compared with menthol. Therefore, a combined use of a menthol derivative and another cooling agent, for example, a polyhydric alcohol (JP-A-10-194926), or a combined use of menthol, camphor, mint, eucalyptus oil and the like (JP-A-06-329528). Or a combination with ethanol and isopropyl alcohol (JP-A-10-231)
No. 238) has been devised to obtain a higher refreshing feeling.
However, these did not maintain a sufficient refreshing feeling.

[0004] An object of the present invention is to provide a skin cosmetic which can maintain a high refreshing sensation for a long time by using a menthol derivative.

[0005]

Means for Solving the Problems and Embodiments of the Invention The present inventors have made intensive studies to achieve the above object, and as a result, by adding silicone oil, the menthol derivative can be efficiently attached to the skin surface. And found that a refreshing feeling can be exhibited more effectively. Furthermore, they have found that the incorporation of a water-insoluble spherical powder further improves the sustainability of a refreshing sensation, which has led to the present invention.

Hereinafter, the configuration of the present invention will be described in detail. Examples of the menthol derivative used in the present invention include menthyl lactate, menthoxypropanediol, menthyl hydroxybutyrate, mentoxifuran, and menthyl glucoside. The amount of these compounds is preferably 0.001 to 10.0% by mass, more preferably 0.01 to 3.0% by mass.

[0007] When the amount is less than 0.001%, it is difficult for a user to recognize a refreshing feeling under normal use conditions. On the other hand, when the content exceeds 10.0%, the refreshing sensation is not a pleasant sensation but may lead to a feeling of heat.

The silicone oil used in the present invention includes octamethylpolysiloxane, methylpolysiloxane, highly polymerized methylpolysiloxane, crosslinked methylpolysiloxane, methylphenylpolysiloxane, trimethylsiloxysilicic acid, octamethylcyclotetrasiloxane, Decamethyltetrasiloxane, decamethylcyclopentasiloxane, methylpolycyclosiloxane, polyoxyethylene / methylpolysiloxane copolymer, poly (oxyethylene / oxypropylene) methylpolysiloxane copolymer, polyoxypropylene / methylpolysiloxane It is a polymer or the like. Preferably, methylpolysiloxane, decamethylcyclopentasiloxane, octamethylcyclotetrasiloxane, methylpolycyclosiloxane and the like having a viscosity of 10 cSt or less are preferable.
That is, a low-viscosity silicone oil having excellent elongation on the skin is preferable.

The amount of the silicone oil varies depending on the type and product form of the silicone oil, but is preferably 0.1 to 3.0% by mass. When the amount is less than 0.1% by mass, the effect of spreading the preparation containing the menthol derivative on the skin surface is not recognized.
Most of the product types cause poor usability such as sticky feeling and squeaky feeling.

The water-insoluble spherical powder used in the present invention includes polyethylene powder, polystyrene powder, nylon powder,
Organic powders such as cellulose powder, cellulose acetate powder, polymethyl methacrylate, and silicone rubber powder, silicone resin powder, silicone composite powder, polymethylsilsesquioxane powder, calcium alginate powder, magnesia silica, silicic acid anhydride, etc. Inorganic powder and the like. Preferably, polyethylene powder, polystyrene powder, nylon powder, cellulose powder, cellulose acetate powder, polymethyl methacrylate, and silicone powder are preferred. That is, it is considered that these products are excellent in carrying a preparation containing a cooling agent on the powder surface without impregnating the inside of the powder, and function to effectively supply the cooling agent to the skin. .

The average particle diameter of the water-insoluble spherical powder is 1 to 10
0 μm is preferred. When the particle size is less than 1 μm, the preparation cannot be sufficiently supported. When the particle size exceeds 100 μm, the powder itself may give a feeling of roughness or squeaky feeling.

The skin cosmetic composition of the present invention comprises a lotion, an emulsion,
It can be prepared in various dosage forms such as gel, cream, mist, aerosol spray, roll-on and the like, and known components can be blended to prepare various skin cosmetics by a conventional method.

The skin cosmetic of the present invention may contain a fragrance. Examples of the fragrance include hydrocarbons such as aliphatic hydrocarbons, terpene hydrocarbons and aromatic hydrocarbons, aliphatic alcohols, terpene alcohols, and the like. Alcohols such as aromatic alcohols, aliphatic ethers, ethers such as aromatic ethers, aliphatic oxides, oxides such as terpene oxides, aliphatic aldehydes, terpene aldehydes, hydrogenated aromatic aldehydes, thioaldehydes, Aldehydes such as aromatic aldehydes, aliphatic ketones, terpene ketones, hydrogenated aromatic ketones, aliphatic cyclic ketones, non-benzene aromatic ketones, ketones such as aromatic ketones, acetals, ketals, phenols, Phenol ethers, fatty acids, terpene carboxylic acids, hydrogenated aromatic carboxylic acids, Acids such as aromatic carboxylic acids, acid amides, aliphatic lactones, macrocyclic lactones, terpene-based lactones, hydrogenated aromatic lactones, lactones such as aromatic lactones, aliphatic esters, furan-based carboxylic acid esters, aliphatic Cyclic carboxylate, cyclohexyl carboxylate, terpene carboxylate,
Synthetic fragrances such as esters such as aromatic carboxylic acid esters, nitromusks, nitriles, amines, pyridines, quinolines, pyrroles, indole and the like, and natural fragrances from animals and plants, natural fragrances and / or synthesis One or more kinds of compounded fragrances including fragrances can be mixed and used.
