Abstract

PURPOSE:To provide a cosmetic base, by washing the dried leaves of KUROHA- GINNANSO (Chondrus yendoi), AKAHA-GINNANSO (Chondrus ocellatus) or their mixture with water, immersing the leaves in water to reconstitute to raw algae, irradiating with ultraviolet radiation, and drying and pulverizing the product. CONSTITUTION:The KUROHA-GINNANSO, AKAHA-GINNANSO or their mixture (red algae produced in the coastal waters of HOKKAIDO Island, Japan) is dried, and the dried leaves are washed with water, and immersed in water for about 15min to reconstitute to raw algae. The product is irradiated with ultraviolet radiation, dried, and pulverized to obtain the objective cosmetic base. The UV-irradiation is carried out until the reconstituted leaves having wet surface becomes whitish (usually for 2-6hr). Dissolution of the resultant fine powder in water gives viscous liquid, which has lubricating and moistening effect to solften, tighten and smoothen the skin.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a cosmetic base that is applied to the skin to soften, tighten, or smooth the skin.

BACKGROUND ART Conventionally, kappa-type carrageenan produced from the original red algae has been added to cosmetics for lotion application for the purpose of thickening.

However, producing kappa-type carrageenan from the above-mentioned raw rose requires steps such as alkaline branding, extraction treatment, dehydration treatment, and drying treatment, and the production cost is also disadvantageous.

The present inventor is currently at the stage of considering a method for producing carrageenan by using these red algae as raw algae, as a new use of Red algae or Red algae, which are produced in large quantities in the waters around Hokkaido. The dried leaves of these raw algae are immersed in water to return to the raw algae state, then irradiated with ultraviolet rays, dried, and pulverized.The resulting powder is dissolved in water and is used as the basis for cosmetics. The present invention was made based on the finding that the compound is suitable as a drug.

The purpose is to provide law.

The present invention will be explained in detail below.

The present invention involves washing the dried leaves of A. japonica, . It is characterized by

Ch.
ondra yendoi (also known as Nijitsunomata in Japanese)
As mentioned above, glossum japonicum) is a red frost produced in the waters around Hokkaido, and so far it has only been used as a raw material for manufacturing plaster as a wall material.

In the tree invention, it is important to dry the raw algae and collect only the leaf bodies, wash the leaf bodies with water, and then immerse them in water to return them to the raw algae state. Irradiation does not yield the desired base.

The above-mentioned return treatment is preferably carried out by immersing the washed leaves in water for about 15 minutes. Then, ultraviolet rays are irradiated onto the leaves that have been reconstituted in this way while still wet. It is preferable that this ultraviolet irradiation is carried out until the lobes take on a whitish color. Usually, the period of time is about 2 to 6 hours. Note that if this ultraviolet irradiation is performed on a small scale, solar drying may be used instead.

In that case, do it for about 2 days for a few hours a day.

The foliage becomes white and dried by the ultraviolet irradiation, and is pulverized into a fine powder to produce a product.

When the fine powder obtained in the above-mentioned manner is dissolved in water, it becomes a viscous liquid, which is used as a base for cosmetics. For example, when the above liquid is added when preparing cosmetics such as lotions and creams, it has the same effect on the skin as Zimda carrageenan, which is conventionally used as the above base.
That is, when applied to the skin, it has a lubricating and moisturizing effect that makes the skin soft, firm, and smooth.

Incidentally, since Black-crowned nightwort and Red-backed rock-hard are rich in vitamins B1 and B2 + amino acids and minerals, they have traditionally been used as raw materials for plaster, as if they were derived from the above-mentioned original algae. It has the advantage of being able to provide a base for cosmetics that exhibits skin effects comparable to kappa carrageenan by a simple method from Kappa carrageenan and Kappa carrageenan, which have been used only in Japan.

EXAMPLES The present invention will be explained in more detail with reference to Examples below.

Example 1 After immersing 1 to 9 pieces of D. japonica dried to 22 g of water in 3 j of water for 20 minutes, the water was drained and the pieces were placed in a cylindrical wire mesh and irradiated with ultraviolet rays for about 2 hours while rotating. This irradiation causes the thallus to turn white. Cut off the stems that do not turn white, and dry only one leaf by ventilation drying until the moisture content is less than 10%, and grind it into a fine powder using a pulverizer. white fine powder 32
011 is obtained. Evaluate 10011 of this fine powder,
Add 1 cup of water to the mixture, heat to 60~70°C to dissolve completely, and after cooling, cover with cloth. The resulting viscous liquid is further boiled for several minutes to sterilize it, then covered and left to cool.

Regarding the black/) Ginkgo extract and glycerin obtained in this way, and the powdered epidermis as the extraction residue,
The weight of water contained when equilibrium is reached at a relative humidity of 90 cm is 100 cm, and when the relative humidity is reduced to 30 cm, the decrease in moisture is measured after 60, 180, and 300 minutes, and the moisture release rate at each time is estimated. .

We compared the moisturizing power.

As a result, as shown in Table 1, it was confirmed that the extract of Physcomitrella sinensis has a high moisturizing ability similar to that of glycerin.

Table 1 shows an example of producing a lotion using the extract of the black-spotted chinensis obtained as described above as a base.

50 parts by weight of extract of Physcomitrella sinensis, 20 parts by weight of ethyl alcohol, and 29 parts by weight of deionized water.

0.7 parts by weight of Lenapeptone (rB elementary decomposition product of cervid muscle) and 0.3 parts by weight of fragrance were uniformly mixed,
Filter and use as hand lotion.

Example 2 Moisture 22e! 700g of dried black-and-white radish
and 20% water content dried Akahaginanso 300I, and after immersing this mixture in 3 parts of water for 20 minutes,
Arrange in a thin layer on a wire mesh or screen, and eat 2 pieces per day for 93 to 4 hours.
Dry in the sun for days. The leaves turn white due to ultraviolet radiation from this sun drying.

Cut off the base that does not turn white and grind it to a fine powder.350g of white fine powder is obtained.100g of this fine powder
．． Add water 1) to 9 and heat to 60-70°C to form a viscous liquid and completely dissolve. After cooling this liquor, filter it with F cloth,
Boil to sterilize, cover and let cool to room temperature.

Using 50 parts by weight of the extract of the above-mentioned ginseng mixture thus obtained as a base, 16 parts by weight of white beeswax and 20 parts by weight of cetyl alcohol were added.

1 part by weight of borax, 0.1 parts by weight of 10% lenapeptone water bath solution, 30 parts by weight of water, 2.0 parts by weight of butyl paraoxybenzoate, and a small amount of perfume are uniformly mixed to form an emulsion.
