Does Bioglitter™ dissolve in water, would that not be a good thing?
No Bioglitter™ does not dissolve in water.
Microorganisms found in the natural environment are needed to digest Bioglitter™ and transform it into harmless substances; carbon dioxide, water and biomass. No microbes = No biodegradation
Dissolving and biodegrading are completely different.
Something that dissolves does not go away, it’s still there in the water, it just cannot be seen. For example salt dissolved in seawater; it is still there just you cannot see it, this is very easily demonstrated when sea water dries on the skin, the salt is left behind is clearly visible.
