Abstract
In a method for controlling unpleasant odors in discharge air from containers, rooms or plants in which strong smelling substances such as feces, waste or highly odorous foods are stored or processed, a fluid is introduced into the discharge air in a finely distributed form, which physically and/or chemically neutralizes the odor of the substances contained in the discharge air. The fluid is a 0.1% to 8% aqueous solution of an active substance concentrate which is 55-65 wt.-% triethylcitrate, 17.5 to 22.5 wt.-% 1,2 propanediol and 17.5 to 22 wt.- % di-propylene glycol-methylether. Alternatively, the fluid can also be a mixture of a suitable propellant gas mixture and the active substance concentrate specified above.
