Abstract: A method for treating a fabric having a discrete stained area, wherein the fabric has a first side and a second side, the method comprises the steps of: (a) applying a spot cleaning composition to the discrete stained area of the fabric; (b) contacting the first side of the fabric adjacent the stained area with an absorbent stain receiving article; (c) subjecting the second side of the fabric adjacent the stained a to a heat source; (d) optionally, concurrently or consecutively with Step (a), contacting the fabric adjacent the stained area with a treatment member; and (e) optionally, applying an aqueous rinsing solution to the fabric adjacent the stained area. The spot cleaning composition comprises a bleach, a solvent, a surfactant and water. Also provided are spot removal kits that include instructions for performing the present spot removal methods, and a process for cleaning and refreshing fabrics that can optionally be performed before or after the present spot removal methods.

Abstract: A process for producing a non-particulate laundry detergent comprises the steps of providing a powdered porous carrier material, adsorbing a perfume onto the powdered porous carrier material, and depositing the powdered porous carrier material having adsorbed perfume on the non-particulate detergent product. In another aspect of the invention, a process for producing a non-particulate detergent product having a perfume loaded carrier material coating includes the step of providing a non-particulate detergent composition having an electrically conductive surface. The process further includes grounding the electrically conductive surface of the non-particulate detergent composition. Still further, the process includes providing an electrostatically chargeable carrier material having a perfume adsorbed therein.

Abstract: A method of using steam ironing of fabrics as a way of causing reduction of physiological and/or subjective reactivity to stress in a human is provided. The method includes the steps of providing a stress reducing composition comprising one or more of a volatile natural essential oil and water. The composition is adapted to not cause staining of fabrics. The method includes delivering the stress reducing composition into a liquid container of a steam iron and heating the steam iron. The method further includes releasing vapors of the stress reducing composition produced within the liquid container of the steam iron upon heating into ambient air. The method still further includes the step of causing reduction of physiological and/or subjective reactivity to stress in the human by one of more of transdermal ingestion or inhalation of the vapors by the human.
