Silver in colloidal state is divided into particles ranging in size from 1 to 100 nanometres. It can be obtained by metallic silver dispersion as well asby silver ion reduction.In both cases, metallic silver particles, not silver ions, are obtained as a result.Solutions that contain these particles, called Micellas, are Colloidal Solutions.
Silver ions that are smaller in size than 0.1 nanometres can be obtained when silver salts are dissolved.These are true solutions.
Since 1939, Laboratorios Argenol has manufactured silver-based products such as Silver Iodide,used as a weather modifier, and products based on Colloidal Silver, Collargol, Proteinate , Vitellinate ,Targesine and Targesine with borax, due to the antimicrobial properties of Silver, all of these products are very useful in the pharmaceutical field.
History of Colloidal Silver
The knowledge of Colloidal Silver properties dates back to ancient civilizations.Ancient cultures, such as those of Greece and Rome, used Silver as the material to make kitchen utensils or water recipients, as this metal helped retard the growth of microorganisms that spoil food and drinks.It was once common in the American West to drop a silver dollar into a container of milk to retard spoilage, by preventing the growth of Fungi and Bacteria.
The last years of the 19th century saw the appearance of the first Colloidal Silver products that possessed significantly increased antimicrobial properties due to the small size of its metallic silver particles.It has been used in medicine since that time, although the appearance ofSulphonamides and antibiotics slowed down the development of Colloidal Silver in Human and Veterinary Medicine for a significant number of years.
Nowadays, microorganisms are becoming resistant to pharmaceutical antibiotics, diminishing their effectiveness.For this reason, today, Colloidal Silver is now in resurgence as an important alternative to the use ofantibiotics; in addition to its proven effectiveness against a wide range of germs, due to its way of working, it prevents the creation of microorganism resistance .This is the reason why the use of Silver as an antibacterial agent in Medicine has been increasing lately.
In addition, other applications of Colloid Silver as a antimicrobial agentare being developed in the industrial and food fields.It is being used, for example, in the microbiological purification of water and in the making of antimicrobial textiles.
Effectiveness of Colloidal Silver
Colloidal Silverhas a high degree of effectiveness against a wide range of Bacteria (Gram-positive and Gram-negative), Fungi and Yeasts.
The action mechanism of Colloidal Silver consists of inhibition of the bacterial respiratory enzyme, causing the death of the bacteria in only a few minutes.For this reason, microorganisms cannot develop resistance, as is the case with antibiotics.As opposed to antibiotics, Colloidal Silver is not harmful to other enzymes, leaving them intact. Consequently, Colloidal Silver is absolutely safe for human beings as well as all living multicellular beings.
Colloidal Silver is known, beyond all doubt,to be nontoxic because it is totally excreted from the body.
Fields of Application
Since 1939, Laboratorios Argenol has offered its products Collargol, Proteinate, Vitellinate, Targesine and Targesina with borax, mainly in the Medical field and the Pharmaceutical Industry, coming to be considered the best Silver Colloids on the market.Proof of this can be found in the volume of our exportations to more than 50 countries around the world.
Moreover, throughout its long history, Laboratorios Argenol has developed aline of products using the antimicrobial properties of silver which have applications in diverse fields:
Medicine / Pharmacology / Cosmetics
Antimicrobial Plastics and Textiles
Ceramics / Electronics
