Abstract

PURPOSE:To obtain a soap excellent in the safety to the skin through suppressing skin chapping, and giving the skin dampishness after use through its humectancy, containing, as active ingredient, a sterol extracted from shellfish meat. CONSTITUTION:The meat of e.g. pearl oysters is ground and dried, the lipids in the meat is then extracted with an organic solvent such as chloroform, and the organic solvent is expelled from the resultant liquid; the extract left is then saponified with, e.g. a 0.5-2.0ON KOH ethanol solution followed by extraction with ether, and the ether is expelled from the resultant ether solution; the extract left is then recrystallized with a lower alcohol such as methanol, thus obtaining a sterol. The soap contains this sterol as active ingredient.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soap which is highly safe when applied to the skin and has a moisturizing effect.

[0002]

2. Description of the Related Art At present, soap is widely used as a cleaning agent. However, it has strong detergency and it cleans natural moisturizing factors such as various amino acids that are necessary for the skin, and the skin becomes dry when washed with soap,
It will lose its luster. On the other hand, to solve this,
Synthetic soap has also been developed, but it has a problem in that it lacks in defoaming and does not have a refreshing feeling. There was no soap that had other expected effects and had sufficient safety.

On the other hand, Japanese Patent Laid-Open No. 169509/1990 discloses that sterols are obtained from shellfish meat, especially pearl oyster meat, and used as a raw material for cosmetics.

[0004]

The object of the present invention has been found to be a natural product and safe for the human body, and further, the adverse effect of soap and soap on the skin can be reduced and the effectiveness effect can be exerted. To provide such a soap.

[0005]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present inventors have already provided food or medicine for many years or applied to the human body, and confirmed the safety to the human body. We screened and investigated the animal and plant components that existed, and examined what has a utility value as soap.

That is, the present invention is a soap containing sterols obtained from shellfish meat as an active ingredient.

The method for producing sterols of shellfish meat is as follows: crush shellfish meat, dry it, extract lipids with an organic solvent, saponify the extract after removing the organic solvent from the extract,
It is a method for producing a cosmetic raw material, which comprises extracting with ether and removing the ether from the ether extract to recrystallize the extract with methanol. As shellfish meat, it is two birds with one stone if it is applied to pearl oyster meat that is unsuitable for food and may be polluted by the sea if discarded. First, shellfish meat is shredded and crushed into fine particles. Then it is dried and the lipid is extracted with an organic solvent. Any organic solvent can be used as long as it can dissolve lipids such as chloroform, acetone, ether, ethanol and methanol, and especially can dissolve sterols including ester sterols. Of course, it is better to use a solvent that can be easily removed in the step after solvent removal. These organic solvents may be extracted by one kind, but two or more kinds of organic solvents may be used.
As a method for extraction, a method using a Soxhlet extractor, or a method in which shellfish meat is finely chopped, mixed with an organic solvent, and separated into an organic solvent phase and an insoluble matter phase by centrifugation or the like can be used. . In order to hydrolyze and remove fat mixed in these organic solvent extracts, the organic solvent is first distilled off by distillation or the like. Next, the extract remaining after distillation is saponified to hydrolyze mixed lipids. Although any method may be used for the saponification as long as the saponification reaction occurs, 0.5 to 2.0 normal potassium hydroxide ethanol solution or sodium hydroxide ethanol solution is added and refluxed to 1. A method of heating for 5 to 3 hours is preferable. After completion of the saponification, an organic solvent insoluble in the saponified solvent and in which the sterols are soluble is added and mixed to separate the organic solvent phase. Ether, petroleum ether, chloroform, freon having a high boiling point and the like are suitable as an extraction solvent from the saponification liquid. The organic solvent is removed from this extract by distillation or the like, and the remaining extract is recrystallized using a lower alcohol such as methanol or ethanol as a solvent to purify the sterols. Thus, by subjecting shellfish meat to pulverization, drying, and extraction, the residue becomes a dry powder that is extremely easy to treat, and problems such as marine pollution can be solved. When the purified sterols are added to the emulsion, they act as an emulsification aid, the stability with time increases, the emulsion becomes clean, and the gloss becomes good. These sterols are substances originally existing on human skin and have very good safety. By blending in cosmetics as will be apparent in the examples below,
It supplements the role of sebum, enhances the functions of the skin, and enhances moisturizing and biological defense functions. (Production Example) 100 kg of pearl oysters from which shells were removed were heated, denatured, and then pulverized with a mixer. After freeze-drying this, 50 l of acetone was added and mixed well. After centrifuging this, it evaporated and the acetone was distilled off. To the remaining extract, 0.5 liter of 1N ethanolic potassium hydroxide solution was added, mixed well, and heated under reflux for 2 hours. After cooling the saponified product, 2 l of ether was added,
Mix well and separate only the ether phase. The ether phase was evaporated, and the ether was distilled off to obtain an extract of the desired sterols. Methanol was added to this extract and recrystallization was performed for purification. The yield was 38g.

The method of using the sterols thus obtained from shellfish meat as soap is not particularly limited,
There is no problem at all.

[Prescription example] The following is an example of an actual use method, but the present invention is not limited to this example.

Example-1 Transparent soap Beef tallow 22.0 Palm oil 10.0 Castor oil 4.0 Olive oil 4.0 Ethyl alcohol 20.0 Purified water 20.0 Sodium hydroxide 6.0 Sugar 9.0 Glycerin 3. 0 Production example 1.0 Fragrance 1.0 Dye small amount sequestering agent small amount

Beef tallow, coconut oil, castor oil, olive oil and ethyl alcohol were mixed and heated at 50 to 70 ° C. in a saponification kettle, and separately, an aqueous sodium hydroxide solution prepared by mixing sodium hydroxide and purified water was added dropwise to 70 Saponification was carried out while keeping at ~ 75 ° C. After the saponification was completed, sugar was added while keeping the temperature around 70 ° C., and a mixed solution of glycerin and a 2.5% aqueous solution of conchiolin hydrolyzed was added to obtain a transparent soap glue. Fragrance,
A dye and a sequestering agent were added, mixed, poured into a frame, cooled and solidified, cut, dried, and then molded.

Use test Seven women were divided into left and right faces, one of which was used as an example and the other was used as a comparative example, and was used once or more daily, and a questionnaire was conducted one week later.
