A waterborne concentrate in which nano silver and nano zinc oxide are chemically modified so they disperse in water without re-agglomerating. Particle size is under 10 nm, which is why it is more active per unit of metal than conventional silver biocides. Supplied as a liquid concentrate for you to dose into your own formulation.

1,200 ± 50 ppm nano silver, plus 15,000 ± 200 ppm nano zinc oxide, in a waterborne carrier. At the recommended 0.5–1% dosage that puts roughly 6–12 ppm of silver into your finished formulation.
They do different jobs. Silver carries the antibacterial activity at very low concentration; the nano zinc oxide adds UV attenuation and, because of its colour and dispersibility, is the component that makes the concentrate usable in cosmetic and coating formulations without greying them.
The particles are chemically modified for water dispersion, which is what keeps them at 5–10 nm. Mechanical dispersion on mixing is still required. Dilute with deionised water rather than tap water — chloride will precipitate silver.
