ODORx 9-D-9 is a highly-concentrated general purpose smoke odour counteractant.
As part of the Unsmoke 3-Stage System, 9-D-9 is a specially formulated blend of odor control counteractants, solvents, and detergents that reduce the spread of odor-causing molecules into the atmosphere. 9-D-9 also contains surfactants that help it penetrate into odour damaged surfaces.
These surfactants help ODORx 9-D-9 disperse when it is used as an odour control additive in water-based cleaning solutions. When applied to porous or absorbent materials, the solvents in ready-to-use (RTU) solutions of 9-D-9 vaporise and dry rapidly, thus promoting the desorption of smoky malodours from treated surfaces. The solution must come in direct contact with all contaminated surfaces that might be a source of odour. This provides an initial reduction of strong, objectionable odours.
