Methods for cleaning a textile material, particularly methods of removing one or more stains from a stained textile material, are provided. The methods comprise contacting the stained textile material with a detergent composition or wash solution comprising one or more nanocrystalline metal oxide and/or metal hydroxide particles, which are advantageously capable of adsorbing the stain-causing substance(s) in the one or more stains. Advantageously, the contacting step results in a stain removal index for the portion of the stained textile material bearing the stain of at least 80.

Chemicals for use in decontamination of polluted sites Odor neutralizing preparations for general use on various surfaces; sanitizing preparations for use in institutional and industrial areas
Apparatus and methods for reducing or eliminating undesirable air-borne substances, such as odors, bacteria, viruses, fungi, and toxins, are provided. A filter containing nanocrystalline metal oxide or metal hydroxide particles may be installed within an air handling apparatus such as an existing HVAC unit located within a building, and particularly within a home, or a portable air processor or purifier. The air handling apparatus comprises a blower which pulls air containing various undesirable substances from within the enclosed environment and directs it through a filtering device containing the nanocrystalline particles. The undesirable substances are sorbed by the nanocrystalline particles thereby creating a deodorized stream of air that may then be directed back into various portions of the enclosed environment or vented to the atmosphere.

A61L 9/16 - Disinfection, sterilisation or deodorisation of air using physical phenomena
The invention provides a sorptive sheet material in which finely divided nanocrystalline particles that react with a variety of chemical and/or biological agents are dispersed. The sheet material comprises a fibrous web that is formed of a plurality of fibers that are bonded to each other. The fibrous web contains a relatively high concentration of reactive nanocrystalline particles that are entrapped within the matrix of the fibrous web. Fluids containing toxic agents, such as chemical and/or biological agents, odors and/or odor causing compounds, and toxic industrial compounds, pass into the web and contact the reactive nanocrystalline particles contained therein. The reactive nanocrystalline particles react with, and chemically alter or inactivate the toxic agents. The sorptive sheet material may be used to construct containers, such as remains pouches, for the storing and transporting of contaminated items, particularly human remains.
