The Japanese name is called “Iwadan-Ogi” because of the round-shaped leaves that are considered to be fan-shaped fans. Oiwawachiwa ( Shortia uniflora (Maxim.) Maxim. Var. Uniflora ) distributed from Akita Prefecture to Niigata Prefecture, There are varieties such as Koiwawachiwa ( Shortia uniflora (Maxim.) Maxim. Var. Kantoensis Yamazaki) distributed on the Pacific side from Tokyo to Tokyo, and the shape and size of the leaves are different. Orchardaceae ( Shortia uniflora (Maxim.) Maxim. Var. Orbicularis Honda) is a variety of Iwachuiwa, and its flowers resemble Iwauchiwa but are distinguished by their leaf shape. The leaves are wide oval and the base is round or wedge-shaped, with 5-15 cm flower stems between the leaves, and one light red flower blooms. The main distribution is from the Kinki to Hokuriku and the Sea of Japan side of the Chushin-Etsu area. Shortia galacifolia Torr. Et Gray, which is distributed in isolation from eastern Asian wrinkles, is found in eastern North America and is used to plant rock gardens and forest floors. In addition, there are Shimiwauchiwa ( Shortia rotundifolia Makino) and Amamiuchiwa ( Shortia rotundifolia Makino form. Amamiana Yamazaki).

  Next, although an Example is given and this invention is demonstrated further in detail, it cannot be overemphasized that this invention is not limited only to these Examples. In addition,% used below is weight% unless otherwise specified.

First, a method for preparing components obtained from a Diapensiaceae plant used in the present invention will be exemplified. In addition, Table 1 lists the specific names and use sites of the diaperceae ( Diapensiaceae ) plants used in the present invention, and the extracts 1 to 12 extracted by the respective preparation methods.

<Preparation method 1>
The dried plant was soaked in a 10% by volume 50% by volume ethanol aqueous solution for 7 days at room temperature. The extract was filtered, concentrated and dried under reduced pressure to obtain an extract.

<Preparation method 2>
The dried plant was immersed in an aqueous solution of 50 volume% 1,3-butylene glycol in an amount of 10 times by weight for 7 days at room temperature. The extract was filtered to obtain the desired extract.

<Preparation method 3>
The dried plant is put into the extraction tank of the supercritical fluid extraction device. After adding 0.003% ethanol as an entrainer, in a supercritical state while adjusting the flow rate of carbon dioxide of 15 MPa at 40 ° C. under atmospheric pressure at the outlet of the separation tank to 700 L / hour. Carbon dioxide was supplied. Then, the pressure of the extraction tank was reduced and the extract was taken out.

Therefore, we investigated the combination of ingredients obtained from this plant ( Diapensiaceae ) in skin external preparations.

  The lotions according to Formulation Example 1 to Formulation Example 4 were prepared using the formulation shown in Table 2. In this lotion, the alcohol phase in which (2) to (9) is dissolved in (1) is added to the aqueous phase in which (10) to (12) are uniformly mixed and dissolved, and mixed uniformly. It was prepared by.

In the prescription examples 1 to 4 of the present invention, an actual use test for 6 months was performed in order to confirm the moisturizing effect and the rough skin improving effect. In addition, the prescription which did not mix | blend the component obtained from the plant ( Diapensiaceae ) plant was made into the comparative example. In the practical use test, 40-year-old to 60-year-old women who markedly show dry skin and rough skin symptoms as panelists were used as 20 people per group, and each example and comparative example were blinded twice a day for each group. I was allowed to use it. The skin condition was observed before and after the start of the use test, and the effect of improving the skin condition was evaluated in three stages: “improved”, “slightly improved”, and “no change”. The results are shown in Table 3 in terms of the number of panelists that performed each evaluation.

As is clear from Table 3, in Formulation Example 1 to Formulation Example 4 of the present invention, all the panelists tended to improve symptoms. On the other hand, in the comparative example in which the component obtained from the plant of Diapensiaceae was not blended, there was no panel in which a clear improvement tendency was seen in both the dry skin condition and the rough skin symptoms.
