Different Forms of Colloidal Silver
At this point it is important to mention that there are many other forms of silver, sometimes also called colloidal, though it is questionable that such designation is accurate. There are basically six production techniques used in these silver preparations. An understanding is important because although these other preparations are referred to as colloidal silver, though in fact they are not necessarily.
There are major differences. Although there are microscopic particles of silver present in each of these preparation types, they are not generally as small as ellectrically produced colloid. Though some forms display germicidal, antibiotic, and other effects, they are not always safe and without serious drawbacks when used in the body. laboratory testing and the historical record show that some forms are noted for producing adverse reactions. For instance it is "silver salts" such as silver nitrate that are attributed to causing the bluing of the skin. Electro-colloidal silver, does not have the same historical bad rep, though it is often thrown into the same category and is then guilty by association.
General Colloidal Production Techniques
Note: These are general processes used to create sols, not necessarily colloid of silver.
1. Dissolution Chemically created colloidal dispersions using a solvent. Solvent examples are gelatin, gum arabic, agar-agar, dextrins, starch, soap, bentonite in water. The process usually involves soaking and heating.
2. Mechanical This production is done using a "colloid Mill" this method is one of the old methods used and is no longer used with silver because the particle size is too large.
3. Electrical and Thermal The electro-colloidal process was first done by striking an electric arc under water, though first done by Guyton-Morveau in 1809 with gold. The use of metallic wires precipitated into water using the Bredig apparatus was coined the "Bredig method". Our discussion here with focus on low voltage electrical precipitation created in recent years.
4. Oxidation-reduction This process is the formation of sols by the use of reducing agents. This process has been used extensively to create gold sols / gold hydrosols. but not as often with silver sols. This process was used before colloids as a state of matter were known. Heat and reducing agents such as phosphorus were most commonly used. The preparation process may also involve hydrogen peroxide, formaldehyde, hydrazine and tannin which were used to create the hydrosol. These hydrosols were used for coloring fabric and glass and were initially also used in hospital tests on spinal fluid.
5. Double decomposition This production method uses double decomposition reactions to create sols. They fall into basically the following groups: oxide, sols, sulfide sols and salt sols. Hydrolysis focuses on pH as a focus and involves complicated chemical reactions by creating a base causing hydrolysis that creates a salt that can be either acid or alkaline. For example adding a small amount of a solution of a salt to boiling water. Another example is hydrous oxide is treated with with a small amount of acid or base or of a solution of a salt which is acidic or alkaline and is then dispersed. It is a complicated chemical process normally used to create salts & compounds.
6. Simple precipitation This process is a simple formula. When a solution of substance (A) in liquid (B) is poured into liquid (C) a sol generally arises, if (A) is insoluble in (C) and provided (B) and (C) are capable of being mixed in all proportions. Example: Sulfur dissolves in hydrazine hydrate forming a deep red stable solution, when poured into water the result is a clear bright yellow dispersion that is sensitive to carbon dioxide.
Types of Silver
Electro-colloidally (described above)
Mild silver Protein: (MSP) This process chemically infuses or binds the silver to a protein. The parts per million vary from 20 PPM to 200 PPM and concentrated as high as 5000 PPM.
Powdered Silver: This production method was developed in Russia. It could be described as both a thermal and electrical process. A very high voltage is used to disintegrate" the silver, also known as water soluble silver.
Ground Silver: This process is just like it sounds, Silver is pulverized and ground into a fine powder. This process became obsolete in the 1920's, because it did not create a small enough silver particle.
Silver salts: These are silver compounds, that cannot truly be considered colloidal silver. They are produced chemically or electrochemically. They may posses a positive charge but are usually a silver compound. Below are some examples of these silver compounds, and their historical or present uses.
Silver Sulfadiazine: Bactericidal and anti fungal uses, particularly used in burn cases.
Silver Nitrate: Disinfectant used in podiatry, and placed in infants eyes at birth to prevent blindness. Ulcer treatment.
Silver Iodine: Disinfectant
Silver chloride: Disinfectant
Silver Lactate: Astringent & antiseptic.
Silver oxide: Previously used for chorea & epilepsy
Silver picrate: Uses, moniliasis & trichomoniasis.
