Benefits of technology

This patent describes a new type of air freshener that can be easily dissolved in water to create a liquid spray that can be used to freshen the air. This solid formulation breaks down easily and can be shipped in a liquid form, saving on transportation costs. The formulation method allows for the use of ambient temperature and humidity, without the need for a hot melt. The air freshener can also be used to deodorize surfaces, environments, and air. The patent also describes a method for applying a specific concentration of deodorizing solution to eliminate or attenuate odors. Overall, the invention provides a more cost-effective and easy-to-use solution for air freshening and odor control.

Problems solved by technology

This saves on transportation costs as the solid may be formulated into the liquid composition at the point of use rather than at the manufacturing site.

Abstract

The present invention relates to a solid pressed air freshener and odor neutralizer composition which can include greater than 10% fragrance. The air freshener comprises a fragrance; preferably the fragrance is impregnated within a water soluble substrate made from a foamed vegetable starch, a surfactant and a solidifier. The solid formulations break down easily in the presence of water and may be sprayed, within the area to be freshened.

Description

FIELD OF THE INVENTION[0001]This invention relates to air fresheners and deodorizers and, in particular, this invention relates to water soluble air fresheners and room deodorizers in concentrated solid pressed formulations that are diluted on site by the customer to yield a liquid composition for use in domestic, institutional and / or industrial applications.BACKGROUND OF THE INVENTION[0002]Various types of air fresheners have been made to dispense fragrances and scents to mask or neutralize unpleasant odors or to simply provide a pleasant scent in a volume of air. One type of air freshener involves dissolving a fragrance in a liquid carrier, such as ethanol, isopropanol, or some other volatile organic compound. Fragrances may also be dissolved in water, although it is often necessary to use a surfactant or other emulsifying agent to dissolve the fragrance in water. The fragrance evaporates with the carrier, scenting the air.[0003]Solid form fragrances are more desirable for product...
