Abstract
Kits for consumer activated dispensers of active materials, such as air fresheners, are provided, comprising an inert carrier material, an active material, and a coloring agent. The inert carrier material is specifically designated as being rice hulls, a waste product of the milling of rice for consumption. The kit may take various forms, such as a container in which are packaged the appropriate amounts of rice hulls, fragrance, and colorant. In another form, the kit may comprise a sachet or pad containing the above materials. Further, a pad or sachet, containing rice hulls and a coloring agent if desired, may be subjected to the controlled continuous feed of a water solution of a fragrance, whereby a long term, consistent fragrancing is obtained.
