Silver Citrate is generally immediately available in most volumes. 
High purity, submicron and nanopowder forms may be considered.
Silver Citrate is a multifuctional, natural alternative to triclosan. 
Silver Citrate Solution reduces the viral load against Vaccinia virus more than 99.9% and the result covers all encapsulated viruses, including all corona viruses. 
Suitable for facial/body care, deoderants, hair care, wet wipes and intimate care.
Silver citrate is a white substance with a very limited solubility in water.
Silver citrate is minimally soluble in water, it can successfully be dissolved in citric acid solutions. 
Silver citrate is a preservative system based on a stabilised silver complex, effective against gram positive and gram negative bacteria as well as against yeasts and moulds.
Silver Citrate Hydrate is generally immediately available in most volumes. 
High purity, submicron and nanopowder forms may be considered.
Silver citrate is a white substance with a very limited solubility in water. 
Under the normal physicochemical conditions, 1 part of silver citrate is soluble in 3500 parts of water, which corresponds to 285 ppm of Ag(I) ion in the solution 
Trisilver(I) citrate, 3Ag+·C6H5O7 3−, was obtained by evaporation of a saturated aqueous solution of the raw material that had been obtained from sodium dihydrogen citrate and silver nitrate. 
Silver Citrate features one formula unit in the asymmetric unit. 
There is an intra­molecular O—H⋯O hydrogen bond between the OH group and one of the terminal carboxyl­ate groups. 
Different citrate groups are linked via the three Ag+ ions, yielding a three-dimensional network with rather irregular [AgO4] polyhedra.
The crystal structure of trisilver citrate, which was obtained from mixing solutions of sodium dihydrogen citrate and silver nitrate.
More soluble in boiling H2O; very soluble dilute HNO3, ammonia.
The diluted silver citrate/citric acid complexed solutions have exhibited very strong bacteriostatic and bactericidal activities.

Uses and applications of SILVER CITRATE:
-Preservative component, antiseptic, antifungal, antibacterial, flavoring agent.
-Silver citrate is also intended to be used as an active ingredient in deodorants.
-Antimicrobial: Helps slow the growth of microorganisms on the skin and opposes the growth of microbes
-Deodorant: Reduces or masks unpleasant body odor
-Preservative: Inhibits the development of microorganisms in cosmetic products.
-Silver Citrate is used as an antioxidant.
-To prepare the nano-scale silver carboxylate emulsions and investigate their applications in the preparation of nano-scale silver films, the silver citrate emulsion was synthesized through the reaction of silver nitrate with sodium citrate in the presence of polyvinylpyrrolidone (PVP) as a surface modification agent in water. 
-SILVER CITRATE is used for its antiseptic properties against bacteria, yeast and moulds. 
-SILVER CITRATE is also used in deodorants.
