How is this colloidal silver different from other silver products?

Institut Katharos focuses on a minimal-ingredient approach and lab-verified purity. The hydrosol uses only ultrapure water and a 40 PPM silver concentration, produced under controlled conditions to yield small silver particles for consistent dispersion.

• Made in the EU with Type 1 ultrapure water and triple laboratory verification.
• 40 PPM concentration—balanced for topical and surface use.
• Advanced production yields smaller particles for improved surface interaction.
• Free refillable spray bottle included for targeted application.

What practical ways can I use the spray at home?

The spray format makes it easy to apply lightly to skin areas, linens, or hard surfaces when you want a clear, non-greasy mist. Many customers keep a bottle in personal-care kits, travel bags, or household cleaning caddies for on-the-go convenience.

• Quick misting of skin areas needing gentle coverage or comfort support.
• Light application to fabrics or frequently touched surfaces for fast drying.

How should I store and apply the colloidal spray for best results?
