How are we different?
Our premium quality colloidal silica is manufactured in the Netherlands by Crystal Colloidals. It is classified as "true colloidal silica" with a colloidal content of 100%. Our manufacturer is one of the few worldwide to have achieved a colloidal content of 100%.
With a particle size of 6 nanometres, our product achieves the technically smallest particle size possible. With a surface area of 113.3m²/l, our colloidal silica has the maximum possible surface area. Due to its small particle size, the large number of particles in the solution, and the significant surface area, it exhibits maximum effectiveness even at the low silica concentration of 300ppm. This means that despite its high effectiveness, only a low silica content needs to be applied, in order to avoid placing a strain on the body.
The product contains only ultra-pure silica and distilled water. The water is deionised and revitalised using the Grander method. Unlike silica water with a higher ion content, this product does not need to be kept away from electrical devices due to its stability.
Water plays a significant role in the production of colloidal silica. Our colloid is dissolved in distilled, deionised, and revitalised water. We use light-protected and environmentally friendly amber glass packaging.
