Tinosan, aka Silverion 2400, aka, Silver Citrate
EWG Risk Score:
What is it?
Silver Citrate is a preservative that's marketed as a "natural" alternative. Silver works by breaking down the cell membrane of the bacterium and denaturing the enzymes within, thus killing the cell. Silver citrate is a the salt of silver and citric acid, where silver exists in its ionic form. Silver citrate in the presence of citric acid (which, when sold as this preservative it's a blend of citric acid and silver citrate) is soluble in water. (Source)
What are its risks:
Silver ions, as found in Silver Citrate are extremely potent anti-microbial agents. The problem is that silver ions cannot distinguish between "good" cells and "bad" cells.
- Dissolved ionic silver is the most biologically active form of silver, is highly toxic to all living cells and bioaccumulative.
- Downstream it sticks to fish gills, keeping them from breathing.
- Contributes to antibiotic resistance.
- Silver ions were found to accumulate of the brains and testes of the mammals (mice) studied.
