Metallic Silver W

Metallic Silver W (Micronized) is a non nano high-purity antimicrobial booster designed to augment the stability of natural cosmetic systems. Unlike liquid salts that provide an immediate “hit” of silver ions, this metallic form acts as a sustained-release reservoir. It is used to “boost” the efficacy of organic acids or glycols, allowing for a reduction in the total concentration of traditional preservatives.

Key benefits

  • Preservative Sparing: By adding even a trace amount of Metallic Silver, you can reduce the usage levels of other preservatives

  • Synergistic Protection: It provides a continuous baseline of silver ions () that prevents microbial “re-growth” in products that are frequently opened or used with fingers.

  • Fine pale grey to off white powder
