SILVÉRION® 2400
Antimicrobial Preservative for Personal Care

Skin Active
SILVÉRION® 2400 is a water-soluble natural antimicrobial preservative containing Silver Dihydrogen Citrate (SDC), a revolutionary, novel ionic silver technology for use in personal care formulations.
Features and Benefits
  • Stand-alone preservative in many formulations
  • Easy to dose and formulate
  • High bio-availability in the water phase
  • Cost-effective preservative
  • Use in diverse product forms, including clear gels
  • Effective alternative to formaldehyde donors and parabens
  • Broad spectrum activity
  • Low viscosity solution
  • Excellent water solubility
  • Effective at low concentrations
  • Compatible with a variety of preservatives
  • Good compatibility with cosmetic ingredients

Cosmetic formulators need alternatives to existing preservation technologies due to toxicological concerns, insufficient efficacy or incompatibilities in formulations. SILVÉRION 2400 is an effective alternative that does not compromise quality.

Effective Preservative for Rinse-off and Leave-on Formulations

SILVÉRION 2400 shows broad-spectrum efficacy against Gram-negative and Gram-positive bacteria, yeast and mold. Preservative challenge tests demonstrate excellent efficacy in diverse formulation types.

Preservative Challenge
Versatile Use
  • Proven effective in rinse-off formulations containing anionic, non-ionic and amphoteric surfactants.
  • Emulsions of o/w and w/o type containing anionic and non-ionic emulsifiers can be preserved with low concentrations of SILVÉRION 2400.
  • 0.1% - 0.3% SILVÉRION 2400 can act as a stand alone preservative in many formulations.
  • Can be combined with most common preservatives in formulations that are difficult to preserve.
Easy to Formulate
  • Low viscosity liquid which can be easily dosed and incorporated into the aqueous phase of gels, surfactants, and emulsions produced in cold process.
  • Stable in a variety of formulation matrices.
  • When manufacturing emulsions produced by hot process, SILVÉRION 2400 must be added to the final formulation after the emulsion has cooled. Exposure of SILVÉRION 2400 to pH higher than 7 should be avoided to achieve optimal formulation stability.
Use Levels
  • Typical use concentration of SILVÉRION 2400 is between 0.1% to 0.3% in leave-on and rinse-off formulations.
