What is colloidal silver?
Colloidal silver is a suspension of silver particles in an aqueous solution, which has been used for many years in various contexts.
It is primarily used for its antiseptic and purifying properties, particularly for surface disinfection, water treatment, and certain external topical applications.
For external use, it can be applied to the skin or mucous membranes as a local cleansing agent.
Skin hygiene
Silver is used in various applications related to skin and topical hygiene. The solution can be applied to the skin using a compress or by spraying.
Oral hygiene
Silver is also used in certain formulations intended for oral hygiene and for the control of oral microorganisms and biofilms. Use as a rinse, then spit out.
Antimicrobial properties
Silver is recognized for its activity against various microorganisms, which explains its use in numerous hygiene applications as well as in certain medical devices.
Its formulation is deliberately simple: silver and reverse osmosis water, with no additives, no preservatives, and no stabilizers.
The water used is purified by reverse osmosis beforehand and has a very low conductivity prior to production. Dioxypure colloidal silver is then manufactured and packaged in our laboratory in France, allowing for rigorous control of the production process.

Compliance and regulation
Product compliant with applicable European regulations (REACH, CLP according to applicable classification):
✔️ Regulatory labeling and documentation available.
✔️ Batch traceability ensured.
The CLP classification depends on the specific SDS of the product and its regulatory assessment.
The Tyndall effect: observing the presence of particles
Even if it is not possible to precisely measure ppm at home, it is possible to observe a physical phenomenon characteristic of colloidal dispersions: the Tyndall effect.
How to observe it?
Place the bottle in a dark or dimly lit room, then shine a concentrated beam of light laterally through the solution. The presence of particles capable of scattering light can make the path of the beam visible inside the liquid.
20 ppm or 40 ppm: what is the difference?
The 20 ppm and 40 ppm have the same particle size and therefore do not differ in their assimilation: only their silver concentration changes, with the 40 ppm containing twice as much silver as the 20 ppm.
20 ppm
≈ 20 mg of silver per liter
40 ppm
≈ 40 mg of silver per litre
FAQ - Colloidal Silver
Can I measure ppm with a TDS meter?
Can I measure ppm with a TDS meter?
No, the precise silver concentration cannot be determined at home with a standard device.
This is a particular source of confusion with TDS meters and conductivity meters. A device of this type measures the electrical conductivity of the solution. Even when it displays a value in "ppm," this value does not constitute a specific analysis of the total amount of silver present in the colloidal silver.
Why is the cap difficult to open?
Why is the cap difficult to open?
Our bottles are hermetically sealed, a system that makes opening them more difficult. If necessary, ask for help or use a small pair of pliers.
What is the difference between 20 ppm and 40 ppm?
What is the difference between 20 ppm and 40 ppm?
The concentration in ppm (parts per million) indicates the quantity of suspended silver particles. 40 ppm is more concentrated and suitable for uses requiring more intense action. 20 ppm is suitable for everyday and regular use.
Does the product contain additives?
Does the product contain additives?
No. Our colloidal silver is a pure aqueous solution, free of additives, preservatives, and stabilizers.
