Silver Citrate is a silver salt of citric acid used as a specialty cosmetic ingredient with antimicrobial, deodorant and preservative functions. COSMILE Europe identifies SILVER CITRATE as the INCI name and describes it as “Citric Acid, Silver Salt.” It is used particularly in deodorants and odour-inhibiting foot-care sprays.
Chemically, Silver Citrate can exist in different hydration and stoichiometric forms. PubChem identifies trisilver citrate as 1,2,3-propanetricarboxylic acid, 2-hydroxy-, silver(1+) salt, with molecular formula C₆H₅Ag₃O₇ and molecular weight 512.70 g/mol. A hydrated form is also documented with formula C₆H₁₀Ag₃O₈ and molecular weight 533.74 g/mol.
For cosmetic raw-material procurement, it is therefore important to identify the exact commercial form and specification rather than assuming that every Silver Citrate material has identical water content, silver content or molecular composition.
Silver Citrate is associated with the citrate anion and silver ions. The material is different from elemental silver, colloidal silver and other silver-containing cosmetic ingredients. COSMILE separately identifies Silver, Colloidal Silver and Silver Citrate as different cosmetic ingredients.
The chemical identity reported for trisilver citrate is C₆H₅Ag₃O₇, with a molecular weight of 512.70 g/mol. PubChem lists 126-45-4 among the identifiers associated with Silver Citrate.
Commercial cosmetic materials may instead be supplied as a stabilized Citric Acid (and) Silver Citrate system. The EU regulatory entry specifically describes a mixture containing citric acid monohydrate and silver citrate monohydrate under EC No. 460-890-5.
Silver Citrate has documented antimicrobial, deodorant and preservative functions in cosmetics. COSMILE explains that it helps control the growth of microorganisms, reduces or masks unpleasant body odours and protects cosmetic products from microbial spoilage.
Its cosmetic use is particularly associated with deodorant preparations and foot sprays intended to inhibit unpleasant odour. The antimicrobial functionality is relevant where control of microbial growth contributes to the performance or preservation strategy of the finished formulation.
Silver-containing ingredients require careful formulation and regulatory evaluation because silver concentration, product type, exposure route and the chemical form of silver can all affect the applicable requirements.
Silver Citrate can be used as a specialty raw material in formulations such as:
COSMILE specifically identifies deodorants and odour-inhibiting foot sprays as cosmetic applications for Silver Citrate.
For commercial development, the final formulation should be assessed for compatibility, silver content, stability, packaging interaction and applicable cosmetic regulations.
Silver Citrate should not be treated as interchangeable with elemental silver or colloidal silver. The exact chemical form and the amount of available silver are important formulation parameters.
Particular attention should be given to silver concentration, pH, formulation composition and compatibility with other ingredients. Silver ions can interact with certain substances and may influence formulation appearance or stability.
For quality control, the finished raw material should be evaluated against its actual specification. Important parameters may include identification, silver content/assay, moisture, inorganic residue, elemental impurities, particle characteristics and microbiological quality where applicable.
A universal HPLC assay should not be assumed for Silver Citrate. The appropriate assay method depends on the validated specification and may involve determination of silver rather than conventional organic-compound HPLC.
Silver Citrate is a specialty cosmetic ingredient and antimicrobial raw material requiring controlled technical specifications. Businesses sourcing Silver Citrate in India may require a defined chemical form, silver-content specification, quality documentation and batch-level Certificate of Analysis.
For B2B procurement, relevant searches include Silver Citrate cosmetic ingredient manufacturer in India, Silver Citrate supplier India, Silver Citrate manufacturing in India, Silver Citrate cosmetic raw material supplier, Silver Citrate personal care ingredient supplier and bulk Silver Citrate ingredient supply.
Because Silver Citrate can be supplied as part of a stabilized Citric Acid/Silver Citrate system, customers should confirm whether they require pure Silver Citrate or a specific commercial blend before procurement.
