Abstract: A method for determining the presence of an odorous material on a fabric includes applying a benzofurazan indicator to the fabric, tagging the odorous material with the indicator, exposing the fabric to a light at a predefined wavelength to produce fluorescence of the tagged odorous material, and observing the fluorescence of the tagged odorous material through a bandpass filter. Also disclosed is a system including the fabric, the indicator applied to the fabric and configured to tag the odorous material, at least one light source arranged about the fabric and configured to direct light on the fabric to produce fluorescence of the tagged odorous material, and an imaging device arranged about the fabric to capture an image of the fabric through a bandpass filter with the image including at least one illuminated portion representing the tagged odorous material. Also disclosed is a method for determining the efficacy of a laundry product.

Abstract: Fabric sheet assemblies for delivering malodor control in wash liquor during a laundering process and methods for forming such fabric sheet assemblies are provided. In one example, a fabric sheet assembly includes one or more substrate layers including a first substrate layer. The first substrate layer is configured to absorb and/or adsorb malodor compounds from the wash liquor. An odor controlling composition is carried by the one or more substrate layers and is configured to be released into the wash liquor.

Abstract: The present invention provides liquid cleaning compositions useful in cold water and hard water laundry applications, and methods for making and using such compositions. The compositions of the invention use surfactants or surfactant blends, such as ?-sulfofatty acid esters or mixtures thereof (optionally along with one or more additional components), that have increased solubility/stability at cold temperatures, at higher-than-usual concentrations, and/or in hard water, with the composition remaining as a clear liquid. In certain embodiments, the compositions of the invention may be provided in the form of a unit dose, for example in a water-soluble pack or pouch. In use, the compositions of the invention result in an enhanced detergency along with a reduced amount of residue remaining in the machine, on laundered garments or cleaned dishware or hard surfaces, and on the body in personal care settings, and demonstrate a longer shelf-life, particularly when stored or used in colder temperatures.
