Silver Dihydrogen Citrate
What is Silver Dihydrogen Citrate?
Silver Dihydrogen Citrate is a chemical compound formed by combining silver ions with citric acid, resulting in a stable silver salt known as C6H7AgO7. It functions primarily as a preservative in skincare and cosmetic formulations, where it releases silver ions to inhibit the growth of bacteria, fungi, and other microorganisms. This broad-spectrum antimicrobial action helps extend shelf life and maintain product integrity without relying on traditional preservatives. Typically incorporated into cleansers, moisturizers, and leave-on products at low levels, it offers an alternative to parabens or other synthetic antimicrobials. Derived synthetically for consistency and purity, it leverages silver's natural oligodynamic effect, where even trace amounts disrupt microbial cell processes. Authoritative reviews, including those from cosmetic safety panels, affirm its role in formulations due to favorable stability and compatibility with other ingredients.
