Abstract
Compositions and methods for reducing or eliminating malodors from air and surfaces in contact with air within indoor environments are described. One method provided is for the reduction or elimination of malodors from air and surfaces in contact with air within an indoor environment using hydrogen peroxide in the vapor phase generated and passively emitted from pH neutral to mildly acidic aqueous-based liquid compositions. A second method is provided for the reduction or elimination of malodors from air and surfaces in contact with air within an indoor environment using hydrogen peroxide in the vapor phase as sublimed from solid compositions containing at least one pH neutral to mildly acidic solid hydrogen peroxide-containing compound.
