Our 600ppm (parts per million) concentrate is very potent. A single 50ml bottle is enough to mix up 1 litre of silver colloid at our regular concentration of 30ppm when mixed with water (always use clean, bottled water).
Where particularly strong anti bacterial performance is required spray the concentrate directly onto the affected area.
Designed for international use, carry a bottle with you where ever you might find infection around the world.
WARNING! This product will stain clothing and skin for a period of time.
