DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to the production of basic cosmetics such as creams and makeup cosmetics such as lipsticks.
The present invention relates to a skin cosmetic comprising a sugar cane obtained from sugar cane.

[0002]

2. Description of the Related Art Conventionally, petroleum waxes such as paraffin wax and microcrystalline wax have been used in cosmetics, and animal and plant waxes have been used in carnauba wax.
Candelilla wax, beeswax and the like have been widely used in basic cosmetics and makeup cosmetics. These waxes have a function of, for example, solidifying lipstick or the like, giving luster, improving a feeling of use, and are essential materials for producing cosmetics.

[0003]

The petroleum wax conventionally used is not preferable in view of the recent natural needs of consumers, and it has been desired to use animal and plant wax. . When used as a raw material for cosmetics, animal and vegetable waxes have properties common to wax raw materials such as solidification properties, glossiness, and feeling of use.
Because it is a natural product, it has a generally complex composition, which may cause problems with compatibility with other ingredients, such as separation of emulsification in cream, blooming in lipstick, etc., deteriorating the value of the product. I was letting it.

[0004] Accordingly, an object of the present invention is to provide a cosmetic composition for skin containing a novel wax which satisfies the functions possessed by conventional wax raw materials and which does not cause separation from other blending raw materials. To provide.

[0005]

Means for Solving the Problems The present inventors have conducted intensive studies on a novel skin cosmetic wax made from a plant and found that sugarken wax has an excellent function as a material of the skin cosmetic. This led to the completion of the present invention. That is, the present invention relates to a cosmetic for skin containing sugarken wax.

The sugarken wax used in the present invention is:
Sugar cane mainly exists in the epidermis of the foliage. The wax content in the sugar cane varies slightly depending on the variety, cultivation area, time and weather of the sugar cane. In the present invention, any wax made from any sugar cane can be used. Although the extraction of the wax may be carried out from the sugar cane itself, it is preferable to use the residue in the refining process when producing the sugar in view of economy.

As a method for extracting sugarken wax, a known general method for extracting high melting point lipids can be applied.
That is, for example, using a hydrocarbon solvent such as hexane and the like, the mixture is extracted under heating at about 50 ° C. or higher, and then the extracted solution is cooled and crystallized, and separated into a low melting point fraction and a high melting point fraction. . This high melting point fraction is the wax used in the present invention.
Further, the present wax can be subjected to ordinary refining treatment. That is, deacidification by an alkali or distillation, decolorization by an adsorbent or a chemical decolorizing agent, and a free fatty acid and sugarken wax having an improved color tone can be obtained.

In the present invention, sugar alcohol having a carbon number of 1 to 4 is added to the sugarken wax obtained by the above method, and the mixture is heated, preferably heated to 50 ° C. or more, and extracted.
It is desirable to perform a purification treatment for removing insoluble substances such as resin components. At this time, the quality of the refined sugarken wax, the yield, the safety point of concern with the residual solvent, etc.,
It is desirable to use ethanol as the alcohol.

[0009] The thus obtained sugar Ken wax, melting point 70 to 85 ° C., a light-colored hard waxes mainly composed of palmitic acid octacosyl or myricyl palmitate, skin cosmetics gloss using the same,
In addition to the characteristics of good elongation on the skin and excellent feeling on use, for example, lipstick does not cause blooming, and cream has excellent emulsion stability. This property is even more pronounced when using purified sugarken wax from which insoluble materials have been removed with hot alcohol.

The skin cosmetic of the present invention can be produced by a conventional method by replacing some or all of conventional wax raw materials such as carnauba wax, candelilla wax and beeswax with the sugar sugar wax of the present invention. it can. The amount thereof varies depending on the type of skin cosmetic, but is preferably 0.1 to 50% by weight, more preferably 1 to 20% by weight.

EXAMPLES In the following examples,% is based on weight. Reference Example 1: Production Example 1 of Wax A filter cake used for filtering and separating insolubles of a sugar aqueous solution obtained by squeezing sugar cane was used as a raw material.
1 kg of hexane is added to 1 kg of this dried filter cake.
0 liter was added and refluxed for 4 hours. Next, the hexane solution obtained by filtration was cooled to 5 ° C. and kept for 10 hours. The precipitated solid was filtered and separated, and the residual solvent was removed under reduced pressure and dried.
