Description

[Detailed description of the invention] The present invention relates to cosmetic soaps containing extracts of seaweed.

Seaweeds such as nori, mozuku, and hijiki grow naturally in Japan, and in recent years have been produced in large quantities through aquaculture, and are nutrient bodies rich in amino acids, proteins, minerals, and sugars.

However, it is not known that this nutrient can be used as an ingredient in soap. The present inventor extracted useful ingredients from these seaweeds with alkali and incorporated them into soap.
It has been found that a cosmetic soap that does not leave a tight feeling after use and has a beautifying effect can be obtained.

When producing the cosmetic soap of the present invention, seaweeds such as nori, mozuku and/or hijiki (hereinafter simply referred to as seaweed) are prepared.
Extract with alkaline solution.

As the alkaline substance, caustic soda, caustic potash, soda carbonate, etc. are used. The alkali concentration in the extraction and use solution is 1
-50% by weight, preferably 15-65% by weight. During extraction, the seaweed may be added to an alkaline solution, or the seaweed, water, and alkaline substance may be directly mixed. Extraction temperature is 40-1-10℃, preferably 80-10℃
It is 0゛C. Extraction is usually completed in 4 to 8 hours.

Although the alkaline extract obtained in this way may be mixed with soap, it is preferable to manufacture soap using this and oil and fat, and to have seaweed components present in the resulting soap.

Examples of fats and oils that can be used include beef tallow, coconut oil, castor 7 oil, lauric acid, myristic acid, valmitic acid, stearic acid, and mixtures thereof. In this case, the amount of the alkaline extract used is usually 0.1 to 0.6 parts by weight per 1 part by weight of the oil or fat.

As methods for producing soap, saponification methods, neutralization methods, ester saponification methods, etc. are used. It is also possible to use a part of the alkaline extract in place of the alkaline solution. Transparent soap can also be produced by adding ethanol, white sugar, sorbitol, glycerin, propylene glycol, polyethylene glycol, etc. Additionally, colorants, fragrances, etc. may be added.

The soap thus obtained is molded into a product by methods such as forming a frame and kneading with a machine. This soap contains seaweed extract in an amount of 0.01 to 20% by weight, preferably 0.05 to 5% by weight on a dry matter basis.
contains. Therefore, there is less irritation to the skin <5. Also, after using it, my skin felt smooth.

In the examples below, parts refer to weight.

Example 1 60 parts of caustic soda and 20 parts of water were added to 50 parts of Mozuku,
After stirring and heating (90°G, 8 hours),
95 parts of alkaline Mozuku extract are obtained.

Add 50 parts of ethanol to 1.00 parts of blended fat and oil (65 parts of beef tallow, 60 parts of coconut oil, and 5 parts of castor oil) and mix and dissolve at 65°C. Add 955 parts of the above alkaline extract to this, saponify it at 75"C, and react for about 2 hours. After the reaction is complete, 60 parts of white sugar and 10 parts of glycerin are added. After mixing, appropriate amounts of flavoring and coloring are added. Obtain colored transparent soap fabric.

This was poured into a frame mold, cooled and solidified, then cut, dried, and finished by stamping to obtain transparent Mozuku soap. The obtained Mozuku soap was less irritating (it felt smooth after use).

Example 2 60 parts of sodium bicarbonate and 65 parts of water were added to 5 parts of dried seaweed, stirred and heated (90°C, 8 hours), and then filtered.
100 parts of alkaline extract of seaweed is obtained.

Blended fats and oils (30 parts of lauric acid, 60 parts of myristic acid, 20 parts of palmitic acid, and 20 parts of stearic acid) 100
Add 50 parts of ethanol to the mixture and mix and dissolve at 5°C.

Add 55 parts of alkaline seaweed extract and neutralize at 75° C. for about 2 hours. After the neutralization reaction is completed, 60 parts of white sugar and 20 parts of glycerin are added and mixed, and the fragrance and coloring are further mixed for 11 seconds and poured into a frame mold. After cooling and solidifying,
Transparent seaweed soap was obtained by cutting, drying, and mold finishing. (JJ seaweed soap is less irritating, and after use (
” - It gave me a smooth feeling.

Example 6 60 parts of white sugar and 20 parts of glycerin from Example 2 were added to the soot, 20 parts of ethanol were recovered, and a small amount of fragrance and coloring was added.
1: Mix and pour into a frame mold. After cooling and assimilating, cut and mold and apply Mozuku cosmetic soap.

Example 4 60 parts of caustic soda and 68 parts of water were added to 2 parts of Hijiki (dry matter), stirred and heated (90''C for 18 hours), and then 100 parts of the alkaline extract of Hijiki was added to (1).

Transparent Hijiki soap was obtained in the same manner as in Example 1.
