Mechanism of action
Minute amount of silver ions dissolved in water from NOVARONAQ are inhibit the metabolic functions of bacterial enzyme and suppress their growth.
Effect
Relationship between silver elution concentration and antimicrobial activity
About 105 cfu/mL of bacteria and 0.5 g of Novaron AQ were added to 500 ml of normal bouillon medium diluted to 1/500, and the viable bacterial counts and silver ion concentration were measured after shaking at 25°C.
Excellent antimicrobial activity was observed with increasing silver ion concentration.
Safety
Excellent antimicrobial activity was observed with increasing silver ion concentration.
Safety test results for standard grade AQ-24
| Safety items | Test conditions | Result |
|---|---|---|
| Acute oral toxicity | OECD423 rat (LD50) | >5,000mg/kg |
| Primary skin irritation | OECD404 | P.I.I.=1.8 |

Examples of application
Application in washing water
Washed and dewatered 30g of NOVARONAQ-24 in a mesh bag and polyester fabric in an electric washing machine at the same time. Microbes from the surface of the polyester fabric are taken at 3 hours and 12 hours after washing and cultured on regular agarose gel medium.
Without NOVARON
With NOVARONAQ
Washing with NOVARONAQ shows significant effect on reducing microbial count.
