Abstract
Abstract The present invention relates to an aqueous composition for reducing malodor impression. The composition comprises from about 0.01% to about 1%, by weight of the composition, of perfume wherein the perfume preferably comprises ingredients having a Clog P of 3 or smaller. Optionally, but preferably, the composition comprises from about 0.1% to about 5%, by weight of the composition of, water-soluble cyclodextrin, from about 0.1% to about 10%, by weight of the composition, of water-soluble metallic salt, from about 0% to about 3%, by weight of the composition, of solubilizing aid. The composition is essentially free of any material that would soil or stain fabric and contains less than about 5%, by weight of the composition of low molecular weight monohydric alcohols.
