Abstract
A method and composition for deodorizing soft surfaces such as carpeting and upholstery are disclosed. The method includes the spraying of a liquid composition on a soft surface and allowing the composition to absorb into the soft surface, form liquid agglomerations within the soft surface to the agglomerations can make contact with malodorants disposed within the soft surface. The composition comprises an active ingredient that is a liquid at room temperature with a vapor pressure of less than 0.0035 mmHg at room temperature. For example, the active ingredient can be triethylene glycol. Other ingredients that contribute to agglomeration formation include ethanol, water, fragrance and a combination of at least one nonionic and at least one ionic surfactant.
