    Does anybody know why Silver citrate containing preservatives, such as Silverion are not in the list of Ecocert approved? Any particular reason?

    I am not sure about all that but I generally avoid them like the plague. They have issues with coverage and stability. Several years ago we tried them extensively and either had PET failures or saw long term stability issues.

    There is a company in Texas, that pushed Natural (and that is all I will reveal) that used them extensively. I believe even this company has moved away from them.

    There are just so many better and less reactive preservatives.

    Because Silver is not a plant-based, renewable ingredient which is a criteria for ECOCert.
