L.O.G. four


L.O.G. four is a compatible, antimicrobial liquid that consists of naturally occurring raw materials. By using only carefully chosen ingredients, we consciously refrain from using components containing alcohol as well as other questionable chemical substances.


The antimicrobial effect results from the specific properties of these ingredients, such as their synergetic interaction. They render microorganisms harmless by penetrating them and impairing their metabolism. Due to these synergetic interactions, the innovative AirSolution ingredients are highly effective already in very low concentrations.



  • Clear, water-based liquid (with a neutral odour, slightly fruity-sour)
  • Natural ingredients – analytically the same as they are found in foodstuffs
  • Absolute exclusion of alcoholic and other questionable chemical substances (e.g. silver ions)
  • Non-toxic
  • Compatible with all types of materials and non-corrosive
  • No risk to operators, employees or other types of users
  • Non-allergenic
  • Environmentally friendly

Germ elimination

Surfaces and air in closed spaces

Efficacy test

DGHM / DIN EN 13697


In order to eliminate germs in indoor air and on surfaces, L.O.G. four has to be emitted as a very fine “fog”. This is achieved via ultrasonic nebulization. This way the active ingredient has an optimal concentration in the air and spreads evenly, like air-borne particles.


The active ingredient of AirSolution L.O.G. four is highly effective already in very low concentrations.



  • Non-toxic
  • Does not have to be indicated on the packaging
  • No residues on ingredients or finished food product
  • Usage without interrupting production
  • OEL significantly below the allowed maximal occupational exposure limit
  • No environmental pollution
  • No risk to humans and products in the sense of FOOD DEFENSE
  • Non-hazardous material


Efficacy test according to DIN EN 13697 & The German Society for Hygiene and Microbiology Standard method

The antimicrobial efficacy of L.O.G. four against bacteria, yeasts and mould and especially against pathogens (among others, Salmonella and Listeria) is DIN EN-tested and confirmed by expert opinions.
