Patent number: 6989075Abstract: A dual intensive property tissue. The tissue has a first set of intensive properties including density, surface area, thickness and void volume as presented to the consumer. The consumer plastically activates the tissue by pulling it in tension. A series of slits 44 or other lines of weakness elongate in a direction parallel to the line of tension, allowing the tissue to achieve a second state of intensive properties. The value of the second state of intensive properties is different after activation. The change in value of the intensive properties allows for economies in shipping, where a higher density product is shipped to the consumer. At the point of use, the consumer activates the product to achieve the increase surface area and lower density. The increase in surface area and concomitant decrease in density provides for increased efficacy in cleaning. The plastically activatable state may be provided by a series of slits 44 or other lines of weakness in the tissue.Type: GrantFiled: November 17, 2000Date of Patent: January 24, 2006Assignee: The Procter & Gamble CompanyInventors: Junan Kao, Michelle Renee Gannon, Michael Gomer Stelljes, Jr., Paul Dennis Trokhan

Patent number: 6207635Abstract: A process for preparing detergent agglomerates is disclosed. The process includes the steps of (a) preparing a mixture of detergent components in a mixer, and (b) agglomerating the mixture from step (a) in a moderate speed mixer to produce detergent agglomerates. The detergent components include (1) from about 20% to about 35% of a surfactant compound selected from the group consisting of anionic surfactants and acid precursors of anionic surfactants; (2) from about 0% to about 65% of a particulate phosphate builder selected from the group consisting of polyphosphate, pyrophosphate, and mixtures thereof; (3) from about 6% to about 60% of a particulate carbonate selected from the group consisting of sodium carbonate, potassium carbonate, and mixtures thereof.Type: GrantFiled: August 27, 1998Date of Patent: March 27, 2001Assignee: The Procter & Gamble CompanyInventors: Donald Scott Adams, Bruce Albert Yeazell, Eric Fitzgerald Riddick, Junan Kao

Patent number: 5777165Abstract: N-alkyl polyhydroxy alkyl amines such as N-methyl glucamine having a Gardner Color of less than 1 are reacted with sources of fatty acyl groups such as methyl esters, anhydrides, and/or fatty acids that have greater than 98% transmittance at 460 nm in organic hydroxy solvents such as methanol to prepare N-alkyl polyhydroxy amine amides with good color. The N-alkyl polyhydroxyamines can be purified by crystallization, and/or subjected to reductive bleaching, to provide superior color. The reaction is preferably carried out at low temperature for short periods of time and with low catalyst levels to minimize formation of cyclic products. The resulting amide product can be further purified by treatment with anionic and cationic exchange resins to remove soap and amine impurities. The anionic ion exchange resin can be readily regenerated by acidifying it followed by washing with an organic solvent.Type: GrantFiled: June 7, 1995Date of Patent: July 7, 1998Assignee: The Procter & Gamble CompanyInventors: Junan Kao, Ephraim Lamar Kelly, Vicki Lynn Weber, Michael Steven Gibson, Donald Benjamin Appleby, Joseph Fredrich Sherman, Ronald Edward Pegoli, Mary Celine Schneider, Terry Franklin Formyduval, Larry Nelson Hawkins

Patent number: 5625098Abstract: Amines such as methyl amine are reacted with materials such as reducing sugars in aqueous/hydroxy solvents such as water and/or methanol to prepare N-alkyl polyhydroxy amines. Accordingly, glucose is reacted with methyl amine and the resulting adduct is hydrogenated to yield N-methylglucamine. The N-alkyl polyhydroxyamines can be subsequently reacted with fatty esters to provide polyhydroxy fatty acid amides useful as detersive surfactants. Thus, detersive surfactants are available from non-petrochemical precursors such as sugars and sugar sources such as corn syrup, and fatty acid esters derivable from various fats and oils.Type: GrantFiled: June 5, 1995Date of Patent: April 29, 1997Assignee: The Procter & Gamble CompanyInventors: Junan Kao, Jeffrey J.
