Independent laboratories

Your trust is very important to us.

 

And that is why we are going to share with you numerous documents that many companies keep confidential: their laboratory analyses.

We tell you that we are offering the purest and most concentrated ionic colloidal silver. Below you will see the analysis from different independent laboratories proving what we say.

 

 

We would even like to share the documents and analysis we needed for the product information file (PIF). All cosmetic products which are produced and sold in the European Union have to undergo this procedure ­even though, in fact, only some companies conform with the law.

 

 

 

Summary:

 

  1. Results of the analysis of our ultra pure water type 1

  2. Results of the analysis of the concentration of our ionic colloidal solution

  3. Results of the analysis of the ionic and colloidal parts of the product

  4. Further analysis reports:

 

 

 

1. Results of the analysis of our ultra pure water type 1

Below are the results of two laboratories which analysed the ultra pure water type 1 produced by our water generator. The results are excellent:

 

  • Absence of any kind of bacteria

  • COT (Carbone organique total, en. total organic carbon) less than 1 mg(C)/L

  • Total microbial flora after 44 and 68 hours is 0

  • Very low conductivity (absence of minerals)

 

 
 

2. Results of the analysis of the concentration of our ionic colloidal solution

 

The silver concentration is of paramount importance, is there really 40 mg/l of silver in our solution?

Here are three analysis reports carried out by 3 different laboratories. We asked several laboratories to ensure that you have a solution at 40 ppm:

  • 1st analysis by the SCP (Société du Canal de Provence): Result 37.6 ppm with a measurement uncertainty of 10%

  • 2nd analysis by Boréal Diagnostic: Result 39.9 ppm with a measurement uncertainty of 10%

  • 3rd analysis by Asposan: Result 43 ppm with a measurement uncertainty of 10%

 

 

3. Results of the analysis of the ionic and colloidal parts of the product

 

In the report it is mentioned that for a total of 14,700 silver units, 14,100 units are ionic and the rest (600 units) are colloidal. A quick calculation tells us (14,100/14,700) that the solution is 95.9% ionic.

 

Important note: This analysis dates back to our first tests (June 2015) and that is why a concentration of 15 ppm was registered. Today we produce a higher concentration of 40 ppm as demonstrated in the more recent test above (September-October 2015).

 

 

4. Further analysis reports:

 

Every product on the European market must have a product information file (PIF). The PIF must include several elements which ensure the safety and effectiveness of the product. Institut Katharos chose the company Expertox to provide this.

 

- Challenge Test

 

Laboratory findings:

“The results of the challenge test comply with criterion A of the ISO standard 11930.”

 

 

 
 

- DGT (Dénombrement des Germes Totaux, en. total bacteria count)

 

Laboratory findings:

 

“The results of the total bacteria count demonstrate the microbiological purity of the product.”

 

- Stability test and calculation of the PAO (period after opening)

Laboratory findings:

“No significant changes to the appearance, colour or smell of the product were observed at ­20, 4, 20 and 40°C over a period of 3 months. However, the pH value slightly increased at 45°C after one month.”

 

 

 

- Patch test (dermatological test), 14 volunteers

 

Laboratory findings:

 

“Non-irritating”

 

- Eye irritation test: direct application to the monolayer of fibroblasts on a rabbit's cornea

 

lLaboratory findings::

 

“Negligible Cytotoxicity”
