ANTIMICROBIAL

TECHNOLOGY

Antimicrobial technology

Non-migrating & durable technology with a

broad spectrum of activity against microbes

No migration to the skin nor to the environment

Quick and easy to verify

Outstanding safety and registration profile

Benefits of the BI-OME technology

Long-lasting freshness

Eliminates the smells created by yeast,

fungus and bacteria in the product

Controls or eliminates microbial

staining of the treated article

Antimicrobial agents - Mode of action

Conventional organic and inorganic active substances

Migration

from substrate to bacteria

for antimicrobial action

No migration

mechanical process

for antimicrobial action

Unconventional organo functional silane active substances

Diffuse from the substrate to the microbe:

• Leach or migrate out of the substrate into the

environment

• Are consumed by micro-organisms

• Chemically interrupt (poison) the cell

• May cause adaptive micro-organisms

• Leach out in contact with water or humid

conditions

Migrating antimicrobials

Migrating antimicrobials

Zone of inhibition in agar diffusion tests

Are bounded to the substrate and require a contact by the microbe:

Are bonded to the product surface

Are not consumed by micro-organisms

Mechanically interrupts (stabs) the cell wall

Remain functional for the life of the product

Will not cause adaptive micro-organisms

Non migrating antimicrobials

Organo functional silanes

N-halamines

Grafting by irradiation

Non migrating antimicrobials

Antimicrobial active substances that do not migrate in order

to be active are for example:

No zone of inhibition => no sub lethal concentration => no adaptation

The BI-OME technology: disruption

Cell disruption mechanism

Disruption

Each micro-organism will come into contact

with approximately 25.000 “swords” at the

surface.

Overview of the most important antimicrobial tests world wide

SANITIZED Standard Tests are effected according to the Swiss Norm (SN 195 920 and SN 195 921). Other tests have to be agreed upon.
