Patent number: 6498135Abstract: 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.Type: GrantFiled: August 3, 2000Date of Patent: December 24, 2002Assignee: Procter & Gamble CompanyInventors: Adrian John Waynforth Angell, Paul Amaat France, Les Charles Zorb, Arseniy V. Radomyselskiy

Patent number: 6268332Abstract: The present invention relates to rinse-added fabric softening compositions, including translucent or clear liquid compositions. The compositions of the present invention comprise a polyoxyalkylene alkyl amide surface active agent which provides increased softness to fabrics, increased stability and formulatability to dispersed phase liquids, and provide for a reduced level of principal solvent when formulated into translucent or clear liquid compositions. In the most basic form, the compositions of the present invention comprise: a) from about 1% to about 80% by weight, of a fabric softening active; b) less than about 15% by weight, of a principal solvent, said principal solvent having a ClogP of from about 0.15 to about 1; c) from about 0.5% to about 10% by weight, of a polyoxyalkylene alkyl amide surface active agent; and d) the balance carriers and adjunct ingredients.Type: GrantFiled: May 23, 2000Date of Patent: July 31, 2001Assignee: The Procter & Gamble CompanyInventors: Ellen Schmidt Baker, Rebecca Gayl Baker

Patent number: 6239087Abstract: Detergent compositions containing certain acetals or ketals which hydrolyze upon exposure of surfaces washed in solution of said compositions to a reduction in pH, thereby releasing a fragrance which is characteristic of one or more of the hydrolysis products. The acetals and ketals themselves also form part of the invention; they have a molecular weight of at least about 350; a ClogP of about 4, and a half-life of less than 60 minutes when measured at pH=0 by the pro-fragrant hydrolysis test.Type: GrantFiled: September 22, 1998Date of Patent: May 29, 2001Assignee: The Procter & Gamble CompanyInventors: Hsiang Kuen Mao, Joseph Paul Morelli, Henry Cheng Na, Robert Ya-Lin Pan, Mark Robert Sivik

Patent number: 6235699Abstract: Liquid compositions having a pH up to 7 comprise from 0.01% to 20% by weight of the total composition of a peroxygen bleach, from 0.001% to 30% by weight of the total composition of an ethoxylated nonionic surfactant, from 0.001% to 20% by weight of a zwitterionic betaine surfactant at a weight ratio of the ethoxylated nonionic surfactant to the zwitterionic betaine surfactant of from 0.01 to 20. These compositions are suitable to deliver improved stain removal performance and improved bleaching performance on various inanimate surfaces.Type: GrantFiled: August 3, 1999Date of Patent: May 22, 2001Assignee: The Procter & Gamble CompanyInventors: Valerio Del Duca, Dennis Gerard O'Sullivan, Carlo Ricci, Roberto Scaramella, Stefano Giunti, Sabina Antonioli

Patent number: 6184197Abstract: The present invention relates to polymers containing at least one nitrogen atom, wherein at least one of the nitrogen atoms is linked to an ester group, said ester group bearing an active alcohol. By the present invention, a delayed release of the active alcohol is provided upon contact of the compound with an aqueous medium.Type: GrantFiled: September 1, 1999Date of Patent: February 6, 2001Assignee: The Procter & Gamble CompanyInventors: Stephen Wayne Heinzman, Arnaud Pierre Struillou

Patent number: 5116563Abstract: An improved process for forming a mechanical fastening prong and the prongs produced thereby. The prongs are produced by deposition of a heated, thermally sensitive material onto a substrate, which is transported at a differential velocity relative to the heated material being deposited to form the prongs. Also, the transported substrate may be drawn away from the point of deposition at an angle. By varying the velocity differential between the substrate and the heated, thermally sensitive material as it is deposited and by varying the angle between the substrate and the point of deposition of the heated thermally sensitive material, the fastening characteristics, particularly the shear strength, of the fastening system formed of these prongs may be advantageously modified.Type: GrantFiled: June 28, 1990Date of Patent: May 26, 1992Assignee: The Procter & Gamble CompanyInventors: Dennis A. Thomas, David J. K. Goulait
