Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hard decorative soap and a method for manufacturing the same. In particular, the purpose is to obtain cosmetic soap with good permeability and good lathering by mixing brown algae extract in the manufacturing process of soap.

Sodium soap is the hard soap that has been used in the past. This soap uses raw materials such as beef tallow, coconut oil, palm oil, and hydrogenated oil. After refining these, sodium hydroxide is added and reacted using various saponification methods to thoroughly prevent salting out. conduct, fatty acids) IJ
They were making um salt. Furthermore, when talking about hard cosmetic soap, it generally uses raw fats and oils of 4 parts beef tallow and 1 part coconut oil, adds sodium hydroxide solution to these, blows live steam into it, and heats it to 100℃. do. At this time, the sodium hydroxide was initially added at 6% to prevent salting out of the soap.
It is set to 12 to 12 inches, but once saponification begins, it becomes difficult to separate the soap, so saponify at 20 to 25 degrees. Add common salt or a concentrated aqueous solution of common salt to the saponification solution to separate glycerin and limestone. As a result of this separation, the soap becomes a curd-like lump and floats to the upper layer, becoming curd soap.1 Since glycerin still remains in the curd soap, add water and heat and boil it. Glycerin is removed repeatedly to obtain a soap solution, which is a sodium salt of fatty acids. Furthermore, after washing, water was injected and stirred while heating the Kusoku Ken liquid, and the soap and impurities were separated by leaving it for a long time.

With the above-mentioned conventional general soap manufacturing method, it is difficult to obtain a soap that has a good touch and aesthetic appearance, as well as good transparency and lathering. This invention is a soap that can obtain those things and a method for manufacturing the same.

To explain the manufacturing method of this invention, a soap base used as a raw material for general soap such as beef tallow and coconut oil is heated to 70°C to 80°C, and white sugar, glycerin, and propylene glycol are added to it. Mix and stir, and when it becomes homogeneous, add the brown algae extract and ethanol, which is the key point of the present invention, and stop heating.After that, add a small amount of red No. 401, a legal pigment, to sodium copper chlorophyllin in purified water. After stirring, the fragrance is added and poured into a vat having a predetermined shape.

After cooling for several weeks, the product is extracted from the pulp, cut, molded, packaged, and placed in a container.

Manufacturing method: The above raw materials are cut into small pieces and washed with cold water at about 10°C to remove impurities such as aluminum and calcium adhering to the surface.

Next, let it dry naturally and turn it into a powder. After that, extract with 5 times the amount of ethanol. It is extracted, filtered, and made into a product.

Product Features (1) Properties: This product is a dark green liquid with a slight seaweed odor.

(2) Confirmation test 2 products: 1-1 liter of calcium chloride test solution
When this product is added, a bulky white jelly-like precipitate is immediately produced. 0.05F of this product is burnt, 2N potassium hydroxide is used as an absorption liquid, and it is combusted by the oxygen flask combustion method. After shaking the flask for 30 minutes after combustion, empty the flask, add 15ml of dibrome glacial acetic acid test solution, add 2 to 3 drops of formic acid, shake and leave in a dark place for 2 minutes, then add starch test solution 1-. , the liquid is purple in color.

(3) Purity test: ■Liquid property Add 10 m of water to this product 1- and the liquid 9 is neutral.

■Gelatin ■Test solution 5- Molybdenum ll ammonium test solution ( l → 20) When adding 1-, for more than 5 minutes No precipitation occurs inside◇ ■Starch ■Test solution 5- When adding iodine test solution to does not exhibit

■l Metal: Ethanol of this product 1. Of, the first When operating and testing by method 2, The limit is 20 PPM or less. Ta For the comparison solution, lead standard solution 2.0- Take.

■Arsenic This product is made by evaporating ethanol 1. Add 1O2 nitric acid and 5 m of sulfuric acid to Of, and heat with care. If the liquid does not become colorless to slightly yellow, add 2 to 3 liters of nitric acid after cooling and heat until the liquid becomes colorless to slightly yellow. After cooling, saturated ammonium oxalate solution 15- is added and heated until white smoke is generated. After cooling, add water to make 20ml! When conducting a test using apparatus A using this as a test solution, the limit is 5 PPM or less.

■ Appropriately dissolves in water and does not disintegrate in hot water. ■ Forms fine, stable foam and foams well.

■ Has good cleaning power and is comfortable to use.

■ Good contact with the body.

■ Beautiful products with good color and transparency can be obtained.
