Patent number: 6083893Abstract: The present invention provides a firm, mild, good performing, low-smear semi-solid or solid dishwashing product. The rheology of the dishwashing product is such that structural elements have been separated from functional elements to obtain best structure properties and in-use properties. By using an interlocking mesh of carboxylic acid and/or neutralized carboxylic acid fibers and/or platelets to provide a support structure, the semi-solid or solid dishwashing product can be loaded with superior performing dishcare materials (e.g., mild surfactants) and appearance enhancers without dependence on surfactant-water phase behavior to provide the support structure. As a result, the present dishwashing product is milder than semi-solid dishwashing products currently on the market. The support structure of the present product, and preferably the use of hygroscopic surfactants, provide a product with lower smear than current gel dishwashing products.Type: GrantFiled: September 29, 1997Date of Patent: July 4, 2000Assignee: The Proctor and Gamble Co.Inventors: David Robert Zint, Mark Leslie Kacher, Tony Pace, Robert Owens

Patent number: 5602089Abstract: A method and composition for clean up of an oil based composition using an aqueous solution. The clean up composition includes 5-60% by weight of a solubility controlling component exhibiting pH dependent water solubility behavior and 30-95% by weight of a diluent. The method includes applying the clean up composition to the oil based composition and cleaning the same with an aqueous solution having a wash pH falling within the pH levels at which the solubility controlling component is water washable.Type: GrantFiled: March 8, 1995Date of Patent: February 11, 1997Assignee: Deluxe CorporationInventor: Thomas J. Pennaz
