What is an antimicrobial treatment?

An antimicrobial treatment is applied to a fabric, plastic or other substance to make it resistant to the growth of unwanted bacteria and fungi that can cause stains, odours and rot. Such treatments are applied to:

  1. products that are exposed to severe environments such as tents and awnings,
  2. consumer goods such as socks, underwear and activewear to control bacteria that can cause odours and staining,
  3. products to differentiate them from others on the market,
  4. control dust mites as part of an allergy and asthma program. (See Regulatory Information.)

What is the difference between the terms antimicrobial, antibacterial and antifungal?

Antimicrobial is a general term that refers to an agent or treatment that has either antibacterial or antifungal properties or both.

Antibacterial specifically refers to an agent or treatment that prevents the growth of bacteria.

Antifungal specifically refers to an agent or treatment that prevents the growth of fungi.
