When sorbic acid is added, antimicrobial activity can be improved, Function.

Citric Acid Anhydrous is used as an acidifier in foods that do not like water or powdery foods such as powdered juice, powdered foam juice, powdered sherbet, powdered ketchup and chewing gum. The anhydrous citric acid has stronger acidity than citric acid (crystal) because it has no crystal number, and has colorless transparent crystals, granules or lumps, or white crystalline powder or powder, and has odorless and strong acidity.

Glycerin, also called glycerol, is transparent, sticky and sweet. Until 1948, it was obtained as a byproduct in the process of making soap from the fats and oils of animals and plants, but later it is synthesized more by using propylene or saccharides. Products containing more than 95% glycerol are usually called glycerin. Glycerol is used in a very wide range. It is the basic ingredient of rubber or resin that makes protective paints such as automotive enamel and outdoor paint. When nitric acid and sulfuric acid are added, nitroglycerin becomes explosive substance.

The freezing temperature is lower than that of saline, and since it can be rapidly frozen at a low temperature of about -30 ° C It is used for frozen food, and it is also used as antifreeze, disinfectant, and lubricant.

1,3-Butylene Glycol is used as a solvent. 1,3-Butylene glycol reduces the viscosity and prevents moisture in the atmosphere of high humidity from flowing into the film forming side do.

In addition, 1,3-butylene glycol can stabilize volatile substances, prevent decay by microorganisms, and have a very good distribution coefficient, so that it can act more effectively on the formulation of the antimicrobial composition.

Tourmaline itself has electric charge and weak electric current (0.06 mA) flows, but the weak current (0.06 mA) necessary for human life and the radiated energy far infrared rays and the wavelengths emitted from tourmaline are the same It gives moxibustion and irritation effect to the rest of the human body, restores the original state, regulates heat and moisture to produce anion, and changes acidified skin and body fluids into weakly alkaline.

By the far infrared rays and radiant energy of tourmaline, it exerts the waste of the skin and enhances the natural healing power, so that the metabolism of the human body can be smoothly performed.

The zeolite is a silicate mineral which is structurally loosely bound to each atom of the crystal, so that the water filling the spaces between the crystals is discharged as a high temperature, and the skeleton is maintained, so that other particulate matter can be adsorbed to the inner space. Particularly, the zeolite has excellent deodorizing effect and adsorption effect, so that harmful components can be adsorbed and removed.

For example, the zeolite may have a specific surface area of 500 to 1000 m ² / g and a particle size of zeolite particles of 50 to 300 nm. The zeolite may be prepared by mixing and dissolving sodium hydroxide in pure water and adding sodium aluminate ), And the mixture was stirred for 1 to 2 hours to prepare a mixed solution. The mixed solution was mixed with 1 M of Al ₂ O ₃ , 4 M of Na ₂ O, 10 M of SiO ₂ and 125 M of H ₂ O, At a rotation speed of 250 to 300 RPM for 3 to 5 hours at a temperature of 85 to 105 DEG C, stirring the mixture for 3 to 6 hours at a rotation speed of 150 to 200 RPM at a temperature of 85 to 105 DEG C, And the mixed solution is crystallized by using a microwave heat source at a temperature of 80 to 95 ° C at a rotation speed of 100 to 150 RPM for 1 to 3 hours to synthesize a zeolite crystal, Adjust the pH using nitric acid is stirred with heating for 3 to 5 hours in a dryer, after washing the unreacted material from 75 to 85 ℃ and then 3% to 6.5 to 7.5 and, since ammonium chloride (NH ₄ Cl) solution Followed by stirring at a temperature of 30 to 40 ° C at a rotation speed of 100 to 150 RPM for 15 to 20 hours to prepare a zeolite crystallization solution. Then, 1000 to 1500 parts by weight of pure water is added to 100 parts by weight of the zeolite crystallized solution After stirring, 10 to 15 parts by weight of a 12% silver nitrate (AgNO ₃ ) solution is added and then reacted at a temperature of 35 to 45 ° C for 5 to 10 hours to be washed.
