Colloidal gold benefits:
Nanogold
The gold is processed using high purity raw material and a new processing technology that reduces the particle size to 15nm. This greatly enhances gold's inherent characteristics, such as its catalytic, anti-free radical, dispersion, etc.
The symbol of gold is Au. The gold symbol is Au.
Properties of Gold
Include high security and stability, as well as oxidation resistance and corrosion resistance.
Gold is one the rarest, most valuable metals. It has an atomic number of 196.96654 and a cube face structure.
Physical properties of gold
Gold melting point: 1064.43. Gold boiling temperature: 2808. electronegativity: 2.54, covalent radius: 1.34A, ion radius: 0.85 (+3) A, atomic radius: 1.46A, atomic volume: 10.2cc/mol.
Due to their close atomic distances, gold can form alloys. The atomic radius for gold is 1.46 Mr. These alloys do not consist of compounds but are solid melts.

Product Performance of Colloidal Gold Nano Gold Solu-tion CAS 7440-5:
Colloidal Gold is made by dispersing nano-sized gold particles, 15nm and smaller, into water. The end result will be a stable, neutral color with uniformity. The nano gold solution looks faintly red and not golden brown. By adding other substances, the liquid gold appears blue when it is in a condensed form. The solution can be consumed by humans and is completely safe for contact with the skin.

What is
Colloidal Gold Nano Gold Solution
Produced?
Preparation of gold nanoparticles is done as follows:
1) adding gold chloric acid in deionized water, and adding polyvinylpyrrolidone, sodium dodecyl sulfate, gold chloric acid, polyvinylpyrrolidone and sodium dodecyl sulfate at mass concentrations of 0.01 ~ 1.0%,0.02 ~ 2.0% and 0.0001 ~ 1.0%, respectively;
2) Stirring at room temperature, add 0.01-0.5% hydrazine hydroxide aqueous to the solution mixed in Step 1. Stop adding the hydrazine-hydrate aqueous mixture when pH reaches 6.87.0. Continue stirring for 2030 minutes to obtain a nanoscale gold solution. This preparation method is advantageous because it is done at room temperatures, is simple to do, has gold nanoparticles that are 10-100nm and is small.
Applications of Gold Nanoparticles
The biochemical and physicochemical characteristics of gold nanoparticles allow them to play an important role in many aspects, such as immunoanalysis and biosensors. They can also be used for DNA recognition and detection. Gold nanorods can adsorb DNA and proteins, but will not alter their properties. Gold nanorods, as a carrier of excellent properties, have been extensively studied.
Food, glass and living organisms coloring agent.
A technique for genetic identifiers.
This is used to refine environmental purification materials.
The preservative is used to preserve food and cosmetics.
Add cosmetics with anti-aging effect, whitening, and moisturizing.
Production of medical equipment, health care supplies, beauty equipment.
We produce daily necessities such as food and beverages that are very closely linked to the people's lives. If the beauty mask is made of all kinds of facial masks and toothbrushes.
Store Colloidal Gold Nano Gold solution in the following conditions:
1. Colloidal Gold should not be exposed to sunlight.
2. The product is intended for research or development purposes and the person using it must be a qualified professional.
3. Nanoparticle solutions consist of suspensions of microparticles within water. These dispersions are either used in their original form or can be diluted with compatible (compatible) solvents. The nanoparticles can settle in dispersions during storage. If this happens, you can shake them up (mix) before using.
