Abstract

PURPOSE:To prepare a creamy cosmetic spreadable smoothly over the skin and having high sterilizing effect, by compounding a myristic acid soap with a pasty composition prepared by extracting deodorized hibiscus and mixing the extracted liquid with salicylic acid, lactic acid and glycerol. CONSTITUTION:100pts. of a pasty composition prepared by adding 3-5% salicylic acid, 7-9% glycerol and 3-5%lactic acid to 1,000pts. of the extracted liquid of deodorized hibuscus is mixed homogeneously with 50pts. of myristic acid soap under heating to obtain the objective creamy cosmetic. The ill odor of the hibiscus can be removed by treating the hibiscus with activated carbon prior to the extraction. Since the extracted liquid has high viscosity, it can be spread smoothly over the skin. Salicylic acid has high sterilizing effect, and lactic acid mitigates the stimulation to the skin, protects the surface of skin, and gives smooth and moist skin.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a creamy cosmetic that utilizes the viscosity and spreadability of A. japonica extract.

Huangshu Aoi (hereinafter referred to as "Tororo Aoi") is an annual plant, and the extract (viscous i) obtained from its roots is called Neri and is used in the production of washi paper, and is also used as a medicine. (It is well known that if the roots of A. japonica are damaged when digging them up or washing them with water to remove muddy soil, the roots themselves and the extract itself are extremely susceptible to rotting.) It is a plant root that must be handled with care as it has the property of emitting a foul odor quickly, and both the root and the extract lack shelf life.

Another characteristic of the extract is that the rate of viscosity reduction is extremely rapid, and for this reason, there is a strong need for the development of a method for preserving A. japonica root and its extract, and a method for preventing viscosity reduction.

As a result of many years of research, the present applicant has succeeded in providing a method for preventing putrefaction of the root mallow root and its extract, as well as hair dressings, cosmetics, liniments, and other medicinal ointments using the extract as a main ingredient. Among these, the present invention aims to provide a cream-like cosmetic that uses the extract of A. japonica as a raw material.When digging up .A. japonica from the soil, be careful not to damage the roots. Dip the soil in a 0.5% to 0.7% solution of cresol soap and store it in a cool, dark place.

■ Immerse in a 3% to 5% salt solution and store in a cool, dark place.

■ Immediately wash the roots of Tororo mallow, immerse them in shochu at 35 degrees to the extent that the roots do not come into contact with air, and store in a cool, dark place.

The applicant has carried out the above three methods of preservation, in addition to washing thoroughly with water (rinsing off the soaking liquid and soil-resistant soil), and then covering the A. japonica with activated carbon in an amount of 10% of the root weight of the mollusc for 1 to 2 days.
After a day of incubation, add the same amount of water as the A. molluscum roots and let it stand for another 1 to 2 days, then wash with water to remove the activated carbon, crush the A. molluscum roots, and calculate the amount of A. It is immersed in the same amount of shochu or alcohol at 25 to 30 degrees to extract the components of Aoi mallow and filtered to obtain an extract of Aoi mallow.

Note that room temperature water extraction may be performed using the same amount of water as the crusher.

The number of days to soak in shochu or alcohol (extraction days) is
When the season is from spring to summer, it is about 1 to 2 days, and from autumn to winter, it is about 5 to 7 days.

Derutogi is a colorless and transparent ingredient that is extracted from the root of the molasses in a soaking tank. This extract has a considerably high viscosity.@ Note that this extract has a high viscosity, but under normal conditions it is susceptible to the growth of spoilage bacteria and is susceptible to putrefaction, and the viscosity decreases significantly over time.

Therefore, in Neri's research, there is a need for research on preventing the decrease in viscosity and preventing spoilage.

Now, here are some examples of how to prevent spoilage and viscosity reduction of the A. japonica extract extracted using this method.
80? ■Prepare lactic acid 401 and salicylic acid 40? Mix well with 80t of glycerin and add 1ooo of A. japonica extract to this mixture.
Mix r. To this mixture (liquid), lactic acid 40F is added and mixed (hereinafter, this mixture is referred to as a "paste composition"), and this paste composition is stored in a cool, dark place or in a refrigerator. However, this pasty composition can be stored (prevented from spoilage) and prevented from decreasing in viscosity for a long period of time (in experiments, spoilage and viscosity reduction have been prevented even after 5 years have passed).

In other words, it has been found that salicylic acid, glycerin, and lactic acid are effective in preventing the spoilage and viscosity reduction of the extract of A. japonica. 3%
5% to 5%, glycerin 7% to 9%, lactic acid 3qb to 5%
It has been found that this is possible by using the above means with %.

As mentioned above, the paste-like composition extracted and mixed does not rot and its viscosity does not decrease, but its components are completely different from Neri, which was conventionally used for Japanese paper making (salicylic acid, glycerin, lactic acid, etc.). are mixed.), and
In addition, the use of activated carbon almost eliminates the unique odor of A. japonica, increasing its value as a base for pharmaceutical preparations.

The cosmetic composition of the present invention uses this paste-like composition as a base, and by mixing 10 parts of myristic acid soap with this base 2, a slightly acidic or weakly acidic cream-like substance is obtained.

That is, a white cream-like cosmetic can be obtained by hot-melting myristic acid soap in an amount equal to one-half of the amount of the paste-like composition, and adding and mixing this to the paste-like composition.

This cosmetic product uses activated carbon to deodorize the unique bad odor of molasses and becomes odorless.The extract has a high viscosity, so it spreads well on the skin, and because it uses salicylic acid, it has a bactericidal effect. Not only is it very strong, but the use of lactic acid has the advantage that it is mild in irritation to the skin, has the effect of protecting the skin surface, and makes the skin surface smooth and moist.
