Description

The present invention relates to cosmetics and humectants.

Mulberry leaves are plants that have been cultivated for a long time as food for strawberries. In recent years, their physiological activities have been studied. The extract of Sakuhakuhi, which is an extract extracted from mulberry root bark, is known to have an antioxidant action, a whitening effect, and an anti-inflammatory action, and has been widely used in the cosmetic field. On the other hand, the use of mulberry-derived components other than such Sakuhakuhi extract in the cosmetics field has not been studied.

As for mulberry, it is known that when a stem, a petiole, a branch, or the like is folded, a milky white emulsion component is obtained (for example, Non-Patent Documents 1 and 2). The use of such an emulsion component has not been sufficiently studied, and its application in the cosmetics field has not been studied.
In skin cosmetics, moisture retention is a very important performance (work). For this reason, examination about moisture retention is made about many substances. When a cosmetic containing a component with high moisture retention is used, the skin has a high moisture retention ability, and many troubles in the skin can be improved. In addition, consumers demand that such a moisturizing agent can be exerted by natural plant-derived ingredients, and plant-derived moisturizing agents become important cosmetic ingredients.

An object of the present invention is to find a component having a high moisturizing ability, which is a moisturizing agent derived from a natural plant, and to provide a cosmetic containing the same.

The present invention relates to a cosmetic comprising mulberry milk.
The cosmetic preferably contains 0.01 to 100% by mass of the mulberry milk.
The present invention is also a humectant characterized by using mulberry milk as an active ingredient.

The cosmetic of the present invention can provide an excellent moisturizing effect and the like by blending mulberry milk. In addition, since the mulberry milk of the present invention is derived from a natural product, it also has an advantage of being environmentally friendly even when discarded after use as compared with a synthetic raw material having the above effects. Moreover, there is less stickiness than an oil-based component, and a high moisturizing effect and a good feeling of use can be obtained simultaneously with a smooth feeling after use.

The present invention relates to a cosmetic containing mulberry milk. The present invention has been completed by finding that an excellent moisturizing effect can be obtained by blending mulberry milk, which has not been studied for use as a cosmetic material, into the cosmetic material.

The inventors of the present invention have studied the milk that exudes from the veins (petiole) when the “mulberry leaves” are damaged (hereinafter referred to as “mulberry milk”). As a result, it became clear that such mulberry milk has an excellent moisturizing performance, and the present invention was completed.

The “mulberry milk” in the present invention is as described above, but this “mulberry milk” may be used as it is, or once powdered by heat drying, freeze drying, etc., and used. It may be a thing. Furthermore, what once powdered was mixed with water again and emulsified may be used.

Mulberry milk has not been analyzed sufficiently for the specific components contained therein, and it is not clear what kind of compound causes such moisturizing performance. In any case, however, the effect of mulberry milk is clear.

In the present invention, “mulberry” is a general term for plants belonging to the genus Moraceae and the genus Morus. The present invention belongs to such a genus, and a plant generally called “mulberry” can be used, and specific species and varieties are not particularly limited.
