When you search the colloidal silver on the Internet, may see more information said that the colloidal silver is pale yellow, so you will question the true colloidal silver which is colorless and transparent. In fact, the color of colloidal silver solution is affected by the size of the silver colloidal particles. There are some external use colloidal silver on the market, the color is light yellow or tan, it is because the silver colloidal particles are relatively large. But we prefer to provide customers with high-quality colloidal silver with small particle size and transparency.
True colloidal silver is colorless because the particles are too small, so the light cannot be reflected back. When the particle size is very large or the generator is running for too long and cannot reach the ideal range of 10-30 PPM, the silver ions will stick together to form larger particles and exhibit color.
Under certain adverse conditions, the color of colloidal silver will be light yellow or brown:
1. When the silver particles are too large, will greatly reduce the effectiveness of the product and will not be absorbed through the cell wall.
2. The colloidal silver produced by the relatively rough battery method, has uneven distribution of silver colloid particles and poor stability.
Colloidal silver isn’t a heavy metal, its average particle size is 1nm, making it easy for animals and humans to use. It acts like a mineral in human body. It is same with the natural form of silver found in edible plants such as wheat, edible fungi and edible seaweed.
We research physical methods for the preparation of high-quality colloidal silver for 10 years, providing customers with colloidal silver antibacterial solution with strong bactericidal properties, no chemical added, safe and pollution-free, and has been widely used in cosmetics, medical, pet, agriculture, Animal husbandry and other fields.
