Criteria for selecting raw materials Furthermore, the quality of the lotion according to the present invention largely depends on the concentration of the active ingredient itself, and the concentration is inevitably directly related to the selection of citrus fruits to be used and the concentration of sprayed pesticides. To be affected. Therefore, selection criteria for selecting a preferable raw material of the present invention will be described below. 1. Low-pesticide, organically grown citrus fruits. 2. Plucked green citrus fruits, not ripe citrus fruits. 3. As for mulberry leaves, spring new leaves are preferable.

Safety to Skin First, safety has to be a top priority for a lotion. However, it is a well-known fact that citrus fruits, for example, contain fucocoumarins, which are harmful components that generate "spots" in response to ultraviolet rays. Usually, it is common to produce a lotion after removing such dangerous components. However, when the above-mentioned 4 kinds of raw materials including mulberry leaves are blended in a fixed ratio, the respective components are well harmonized, the harmful effects are suppressed, and conversely, only the effectiveness is synergistically increased. To be

[0014]

The present invention will be described in more detail with reference to the following examples. The following is a component table of a lotion according to an embodiment of the present invention. Ingredients Mulberry leaf extract: 27.5 wt% Iyokan extract: 25.0 wt% Kanatsukan extract: 25.0 wt% Mikan extract: 22.5 wt% pH: 5.0 (Cosmetic raw material standard, general test Method, pH measuring method) It has been confirmed that the same effect and safety as those of the present example can be secured if the variation in the manufacturing process is about ± 5% in the above component ratio.

Manufacturing method Mulberry leaves, Iyokan, Kanatsukan and mandarin oranges are washed with tap water, and immediately wiped off with a dry clean cloth or cotton towel. Then, first, these citrus fruits are sliced into 2 cm to 5 cm width with a commercial cutter. Then, only the peels are mechanically peeled from these citrus cut into pieces.

The process of extracting the components for each type from the remaining peel is carried out as follows. That is, the solvent amount is 20 liters for 20 kilograms of Iyokan and 20 kilograms of sweet summer citrus, and 10 kiloliters for 20 kilograms of mandarin orange. Although a general alcohol is used as a solvent for extraction, ethanol is used as a solvent in this embodiment.

Each of these various citrus peels is immersed in a solvent set in accordance with the amount of the peels for about 2 weeks at room temperature in the dark, and then only the peels are taken out to obtain an extract. Then, the respective extracts obtained in this way are filtered with a membrane filter and mixed and stored in a stainless steel container.

The mulberry leaves that have been washed and wiped dry are steamed with steam and then dried in the shade for one day. With respect to 20 kg of the mulberry leaves thus obtained, the solvent amount was set to 30 liters, and an extract of mulberry leaves was obtained in the same manner as the above-mentioned method for obtaining an extract of citrus fruits. Then, this extract is filtered through a membrane filter, mixed with the above-mentioned citrus mixed extract and stored. A required amount of the thus-obtained mixed extract of mulberry leaves and citrus fruits is taken out each time, filtered through a membrane filter of triple mode again, and filled in a product container as it is.

Safety Test As a safety test, when the extract of each component was applied alone to the skin, there was an example in which the harm was confirmed by the action of furocoumarin, but 4 according to the present invention No such toxicities were observed when a mixed extract of different types of components was applied.

[0020]

Since the lotion according to the present invention has the contents as described above, in addition to the conventional general lotion effect and skin protection action, it also has a skin lightening action and a skin moisturizing action. More excellent effects and safety can be obtained. In particular, since it uses only natural ingredients and mixes them together, there is no risk of side effects, and a natural lotion that does not decay or deteriorate for a long period of time without the addition of synthetic chemicals such as preservatives. be able to.

Further, since it is possible to use only domestically produced raw materials and the manufacturing method is simple, there is no need for complicated and large-scale equipment, which is rational and cost-effective. Also, because the mulberry leaves used for sericulture are reprocessed without being discarded, it is a residue of the sericulture industry, as it was possible to produce emulsifiers from the large amount of residues that were generated in the crude oil refining process in the past. The mulberry leaves can be effectively reused. That is, there is an effect that it can bring a new related business field to the sericulture and contribute to the development of the domestic sericulture.
