Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to cosmetics, and more specifically, it contains a flow demanita extract and a specific oil agent,
The present invention relates to a cosmetic which has a smooth and rich feeling of use, is less sticky, has good compatibility with the skin, and retains a moist feeling.

[0002]

2. Description of the Related Art Conventionally, a large amount of a water-soluble polyhydric alcohol such as glycerin or 1,3-butylene glycol or a water-soluble polymer has been used for the purpose of imparting a moisturizing effect to cosmetics, that is, a moisturizing effect. I've been told. However, when a large amount of these water-soluble polyhydric alcohols and water-soluble polymers are added to cosmetics, there is a drawback in that they become sticky and the skin does not fit well.

Further, in order to obtain a smooth and rich feeling of use, a paste-like oil agent such as lanolin and vaseline has been blended with cosmetics, but on the other hand, a feeling of richness is obtained. It has the drawback that it becomes sticky, and it was difficult to give it a moist feeling as well.

[0004]

Therefore, it has been desired to provide a cosmetic which is smooth and rich, has a good feeling of use on the skin, is excellent in the feeling of use such as moisturizing, and is less sticky.

[0005]

Under such circumstances, as a result of various studies by the present inventors, when a combination of a flow demanita extract and a specific oil agent is blended and combined, extremely excellent use is achieved while suppressing stickiness. The present invention was completed by finding that a cosmetic having a feeling can be obtained.

That is, the present invention provides the following components (A) and (B) (A) Floudemanita extract (B) Macadamian nut oil, rosehip oil, medfoam oil and cholesteryl-12-hydroxystearate. The present invention provides a cosmetic containing one or more oil agents selected from the following.

The flow demanita extract which is the component (A) of the cosmetic composition of the present invention can be produced, for example, by the following method. That is, one of the plants native to Mexico, Flor de Manita (aka MACPALXOC
Also referred to as HITL] by heat extraction of the dried product or pulverized product of the dried product with an extraction solvent, and after extraction, the extract is filtered to obtain an extract, or the extract may be further cooled to 60 ° C or less if necessary. A flow demanita extract can be obtained by concentrating under reduced pressure while heating at a temperature of 3 to dryness to obtain a dry extract.

As the extraction solvent, alcohol (methanol, ethanol, propanol, isopropyl alcohol or the like), water or the like can be used, or a mixed solution of these can be used. An example of a preferable extraction method is a method in which hydrous alcohol having an alcohol concentration of 20 to 70% is used and extraction is performed at a temperature of about 50 ° C. for about 1 hour, and an extract can be efficiently obtained.

The content of the flow demanita extract in the cosmetic composition of the present invention is preferably 0.00 as a dry solid content.
It is from 01 to 10% by weight (hereinafter simply referred to as "%"), and more preferably from 0.01 to 5%. When the extract is used, the concentration of the extract is not limited as long as the content of the dry solid as a solute is within the above range. The content of this flow demanita extract is 0.000
If it is less than 1%, the sufficient effect may not be obtained,
Further, even if the content exceeds 10%, the effect is not further increased.

On the other hand, of the oil agents used as the component (B) of the present invention, macadamian nut oil is made from macadamian nuts produced in Australia, Hawaii, Africa and the like, which is subjected to treatments such as pressing and solvent extraction. It is a liquid oil obtained by applying to.

Rosehip oil is rosehip seed, which is a kind of wild rose that grows in South America and Europe, and medfoam oil is a perennial medfoam fruit that grows in western Africa and the Pacific coast of North America. Is a liquid oil obtained by squeezing and solvent-extracting these as raw materials.

Furthermore, among oil solutions, cholesteryl-1
2-hydroxystearate and cholesterin and 12-
It is an ester of hydroxystearic acid and is used as a paste-like oil agent.

These components (B) may be used either individually or in combination of two or more. When Macadamian nut oil, rosehip oil or medfoam oil is blended alone, the feeling of use is improved. From the aspect of 0.
It is preferable to add about 001 to 50%, and when adding cholesteryl-12-hydroxystearate alone, it is preferable to add about 0.001 to 10%.

The cosmetic of the present invention can be produced by blending the above-mentioned essential components (A) and (B) according to a conventional method, and its dosage form includes emulsion, cream, It can be a lotion, a pack, a cleansing agent, or the like.

Further, in the cosmetic of the present invention, in addition to the above-mentioned essential components, aqueous components, powders, surfactants, other oils, moisturizers, alcohols, pH which are used in ordinary cosmetics.
A regulator, an antiseptic, a dye, an antioxidant, an ultraviolet absorber, a thickener, a fragrance, a beauty ingredient and the like can be appropriately blended as necessary.
