Definition of colloidal silver

Colloidal silver, also known as colloidal silver solution or colloidal silver water, is a mixture of ultrafine silver particles suspended in a liquid. It is normally used in the biocide industry for disinfection. Colloidal silver is available in the form of powders, gels, and liquids in all possible combinations of particle size, concentration, and color.

Colloidal silver consists of colloidally dispersed silver particles ranging in size from 0.001 to 0.1 microns. Normally the concentration of colloidal silver in the solution is 5-10 ppm. The particles are distributed in the solution in such a way that they are not visible to the naked eye. Colloidal silver can be slightly yellow, yellowish, gray, or tan in color.

Benefits of Colloidal Silver

  1. Antibacterial and antifungal
  2. Supports the immune system
  3. Promotes general health

Colloidal silver is subject to the requirements of the European Food Safety Authority (EFSA). Accordingly, only one health claim is permitted: "Colloidal silver contributes to the normal function of the immune system".

History of the Use of Colloidal Silver.

Colloidal silver has a history of more than a hundred years as a natural remedy. It was first discovered by French researcher Charles-Gabriel-Sualin and recognized as an effective antiseptic against bacteria and viruses. Ever since the process of making colloidal silver was invented in 1890, it has been one of the oldest and most trusted natural antiseptics.

Colloidal silver has been used as a natural remedy in various cultures around the world. For example, there are many reports from ancient times and the early Middle Ages recommending drinking colloidal silver. In the 19th century, drugs containing colloidal silver were used to treat anemia, jaundice, and other health problems.

Colloidal silver is available in a variety of different products on the market today. It is considered an effective and natural remedy to treat various health problems and is used by many people as a safe and natural antiseptic. Colloidal silver meets the official requirements of the European Food Safety Authority (EFSA). According to EFSA, can be attributed to colloidal silver

  • that it can support the immune system in cells damaged by free radicals
  • that it has antioxidant properties that can help fight free radicals
  • that it possesses anti-inflammatory properties that may help reduce inflammation
  • that it has antiviral properties that can help kill viruses and bacteria.

Why is colloidal silver still relevant today?

Colloidal silver has been known as a natural component in many areas of life since ancient times. Since the dawn of human history, it has been an essential part of herbal medicine, many medicines, and is used in medicine as an antiseptic. Even today, colloidal silver products play an important role in modern medicine, especially as an adjunct to therapeutic drugs.

Its uniqueness lies in the fact that, in colloidal form, it maintains a perfect balance between particles and liquid, being able to penetrate into the smallest capillaries of the body. Although many uses of colloidal silver have not been proven by clinical studies, it has been shown to have beneficial effects on various medical conditions due to its antimicrobial and anti-inflammatory properties. It has been shown to help fight bacteria, viruses, fungal infections, enterococci, and other pathogens.

According to the EFSA, it can also help to regulate the intestinal flora and strengthen the immune system. When combined with a healthy and balanced diet, it can also help boost the immune system to maintain overall health.

II. Production of colloidal silver

Colloidal silver is a very fine silver powder that is produced from silver ingots by electrolysis. During electrolysis, the silver is dissolved in water in a special electrolysis cell. To produce colloidal silver, the dissolved silver is connected to electrodes through which current flows. The current creates an electrolytic field that breaks down the silver ions into very small particles. These particles are so small that they float in water and are known as colloidal silver.

The proportion of silver ions in the water can be influenced by changing the settings of the electrolyser. In this way, different concentrations of colloidal silver can be produced.

The following health-promoting properties can be achieved through the production of colloidal silver:

  • Support of the immune system
  • Reducing the risk of inflammation
  • Promote rapid wound healing
  • Positive effects on intestinal health
  • Promotion of general well-being.

These effects are listed in the regulation of the EFSA (European Food Safety Authority) as traditional contributions to general health.

Different manufacturing processes of colloidal silver

Colloidal silver is manufactured using a variety of processes based on the basic principles of electrochemical plating. The main procedures are

  1. Electrolysis : In electrolysis, silver is dissolved in an electric field and dissolved in water by the electromagnetic field. The concentration and particle size of the silver ions can be controlled by the number of anodes, current, and access to oxygen.
  2. Reduction : In this process, a liquid solution is made from silver nitrate, water, and a reducing agent such as caustic soda. The mixture is then reduced at a specific temperature and pressure to produce silver particles in the form of colloidal silver and silver chloride.
  3. Adsorption : This process involves preparing a solution of silver nitrate and water, which is then applied to an adsorbent such as activated carbon. The adsorption binds the silver particles to the surface of the activated carbon and then dissolves them as colloidal silver and silver chloride.
  4. Oxidation : The oxidation method involves making a mixture of silver nitrate and water, and then adding an oxidizing agent such as oxygen or ozone. This oxidizes the silver ions to form colloidal silver and silver chloride.

Advantages and disadvantages of the different methods

Colloidal silver can be made in a number of ways, each with their own pros and cons. Which method works best for you depends on the results you want to achieve.

1. Electrolytic method

This method is the most complex and expensive, but also requires the highest quality. In the electrolytic process, electrical impulses are sent through a solution containing silver ions. This creates a high concentration of silver particles that remain in the solution as colloidal silver.


  • Highest concentration of silver particles
  • Production of the highest quality colloidal silver
  • No impurities


  • Very complex procedure
  • Expensive equipment required
  • Comparatively expensive to manufacture

2. photocatalytic process

This manufacturing process is becoming increasingly important because it is less complex and cheaper than the electrolytic process. In this method, light is directed into the solution to trigger a chemical process that releases silver ions into the solution, which are then present as colloidal silver.


  • Less expensive to manufacture than the electrolytic process
  • No impurities
  • Easier and faster manufacturing


  • Lower concentration of silver particles than in the electrolytic process
  • poorer quality than with the electrolytic process

Safety Precautions in the Production of Colloidal Silver

Since colloidal silver poses a sufficiently high health risk, it is important that certain safety measures are observed during manufacture.

It is recommended to wear long sleeves and gloves and not to bring the silver water directly into contact with the skin or mucous membranes. It is also advisable to wear safety goggles and a respirator to protect the production environment.

It is important to ensure that the materials and chemicals used in manufacturing are safe and suitable for their intended purpose. All tools and equipment must be thoroughly cleaned and sterilized before use. To ensure the quality of the colloidal silver, it is recommended that the solution be cold distilled before use.

It is also important to carefully monitor and adjust all components to get the right concentration of silver in the solution. This requires regular monitoring of the pH value, redox potential and particle concentration.

The product must be carefully filled and sealed immediately after manufacture to avoid possible contamination.

It is recommended that consumers refer to colloidal silver from a reliable source.
