Abstract: The present invention relates to liquid detergent compositions comprising a polymeric material which is a suds enhancer and a suds volume extender, said compositions having increased effectiveness for preventing re-deposition of grease during hand washing. The polymeric material which are suitable as suds volume and suds endurance enhancers comprise an effective amount of a polymeric suds stabilizer comprise:
i) units capable of having a cationic charge at a pH of from about 4 to about 12; provided that said suds stabilizer has an average cationic charge density of 2.77 or less units per 100 daltons molecular weight at a pH of from about 4 to about 12;
b) an effective amount of a detersive surfactant; and
c) the balance carriers and other adjunct ingredients;
provided that a 10% aqueous solution of said detergent composition has a pH of from about 4 to about 12.
positive or negative charge at a pH of from about 4 to about 12.

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.
