Silver (Ag) Concentration of 100ppm = 100mg/L

Can be diluted to a lower concentration (usually 5 to 20ppm). 

Fast method: Put one dropperful of 100ppm in a cup of distilled water and enjoy over the course of a day.

Or, dilute to 10ppm and dose more precisely.

Silver has been used for fighting germs and preventing infections for centuries. The nano form of this material is becoming even more popular due to easy applicability and product availability. Well known antibacterial, antiviral and antifungal properties are enhanced by small particle size and large surface area (nanoparticles are thus more efficient).

The product can even be used in cosmetic products, paintings or other individual applications (use your imagination!). Colloidal silver can be added to water-soluble polyurethane wood paint to add antibacterial characteristics (silver does not negatively affect the protective performance of the paint).

Spray it in/on your fridge, bathroom, sauna, produce, or your mouth!

Shipped to you from Canada in an amber glass bottle with dropper. 

Colloidal or Ionic Silver - what is the difference?

Colloid by definition means ultrasmall particles dispersed in a continuous medium (liquid in our case) whose properties depend on the large specific surface area. Ionic by definition means atoms, that are missing an electron, or have an extra electron. Most products advertised as “colloidal silver” contain mostly silver ions, not silver particles, so technically they are silver solutions, not silver colloids.

Visually it should be quite easy: colloid silver is represented by a yellow-to-brown colour, where the hue depends on concentration of silver and the particle size (or the age of the product respectively). Ionic silver products are transparent, the presence of silver ion can be easily verified by adding of the kitchen salt (NaCl) which results in formation of non-soluble silver chloride (AgCl represented by white turbidity). Products manufactured by electrolysis (AC, DC, high or low voltage) are typicaly ionic silver solutions, not colloids.
Majority of vendors declare their ionic silver wrongly as "colloidal" and "nano" product, they usually provide following recommendations: "the product has to be stored in dark glass bottles, avoid sunlight and sources of electromagnetic field (TV, radio, fridge)". These requirements are pointless in case of colloid silver products, they are relevant only to ionic silver solutions:
  • Colloidal silver containing silver nanoparticles does not require to be stored in glass, it does not interact with plastic surface and thus can be delivered in transparent PET bottles enabling visual colour check.
  • Ionic silver, which is wrongly declared as colloidal by many producers, is photosensitive and interacts with plastic surface, therefore many companies use non-transparent glass bottles, that moreover do not allow to check the product colour.
  • Electromagnetic field influences ionic silver, it has no negative effect on colloidal silver by our experience.
  • Cooling of the colloid silver slowers agglomeration of particles and prolongs the shelflife of the product by our experience, please avoid freezing of the product.

Colourless products usually contain no nanoparticles or just a fraction of declared quantity - such products usually contain ionic silver which is photosensitive (therefore stored in non-transparent bottles).



To dilute to 10ppm, the easiest way to remember is to take your colloidal silver concentrate quantity and add it to ten times that amount of demineralized/distilled water. For example, mix one dropperful of concentrate into ten dropperfuls of water. Or, 100mL into 1000mL of water.   

TO BE PRECISE: the actual dilution to 10ppm is your selected concentrate quantity added to nine times the amount of distilled water. For example, add 100mL concentrate to 900mL water.

100ppm x [your concentrate volume] / [desired ppm] = [final volume of mixture]

[final volume of mixture] - [your concentrate volume] = [volume of solvent to mix with]

Note: Please do not use ordinary tap-water for the dilution, it may cause agglomeration of nanoparticles and inhibit product efficiency.


Colloidal silver is distributed in form of stable dispersion in glass bottles (100mL, 100 ppm). Storage in a refrigerator at 2-6 °C is highly recommended. Do not freeze or heat the product! The sooner the product is used, the better; Ideally, within 6 months from the date of manufacture. However, within a year is quite typical.
