ask me

Nowadays, silver nano is being used. came to put in personal care products, pets care, so interested in trying to create a formula, but found that

Black precipitate will always occur in the product. Is this caused by silver reacting with other substances? If adding a chelating agent such as EDTA, will it help? Or do I need to adjust the formula? and would like to know which pH range of silver nano products is suitable for use?
