Patent number: 6331586Abstract: A conductive polymer blend comprising: (a) at least two polymers which are at least partially immiscible with each other, and are present in proportions such that each polymer forms a respective continuous phase and the two respective continuous polymer phases are co-continuous with each other in the polymer blend; and (b) at least one conductive material in particulate or fiber form which is substantially localized in one of said co-continuous polymer phases or substantially localized at a continuous interface between said co-continuous polymer phases. Optionally, the polymer blend may contain a mineral filler and/or a thixotropic thickening agent.Type: GrantFiled: February 11, 1999Date of Patent: December 18, 2001Assignee: Cabot CorporationInventors: Alain Thielen, Baudouin Valange, Stefan Viering

Patent number: 5294364Abstract: An acidic aqueous cleaner, preferably in emulsion or microemulsion form, which is of a pH in the range of one to four and is useful for cleaning hard surfaced items, such as bathtubs, sinks, tiles and porcelains and even some such items which are not acid resistant, such as those of a European enamel known as zirconium white enamel, comprises synthetic organic detergent, such as a mixture of anionic and nonionic detergents, e.g., sodium paraffin sulfonate, higher fatty alcohol ethoxylate sulfate and higher fatty alcohol or phenol ethoxylate, organic acids, e.g., mixture of succinic, glutaric and adipic acids, phosphonic acid, e.g., aminotris-(methylenephosphonic acid) and phosphoric acid in an aqueous medium.Type: GrantFiled: August 3, 1992Date of Patent: March 15, 1994Assignee: Colgate PalmoliveInventors: Michel Thomas, Genevieve Blandiaux, Baudouin Valange

Patent number: 5108643Abstract: Stable microemulsion cleaning compositions are described which, in the absence of opacifying component, appear clear to the eye, and which are especialy useful for cleaning surfaces having oily or greasy soils thereon, which comprise synthetic organic detergent, water, co-surfactant of a described type, and perfume (or equivalent hydrocarbon). The detergent composition may be concentrated and may be employed as is, or it may be in dilution with water, in the form of a similarly clear and stable microemulsion. In process aspects of the invention both the concentrated and the diluted compositions may be employed to remove oily and greasy stains from substrates, such as normally shiny bathroom fixture and floor and wall surfaces, including tiles, by a "spray and wipe" process, which leaves the surface shiny, with minimal or no rinsing needed. When the invented compositions are acidic they are also useful for removing lime scale and soap scum from hard surfaces.Type: GrantFiled: November 7, 1988Date of Patent: April 28, 1992Assignee: Colgate-Palmolive CompanyInventors: Myriam Loth, Claude Blanvalet, Baudouin Valange

Patent number: 5082584Abstract: An improvement is described in microemulsion compositions containing an anionic detergent, one of the specified cosurfactants, a hydrocarbon ingredient and water which comprises the use of a water-insoluble odoriferous perfume as the essential hydrocarbon ingredient in a proportion sufficient to form either a dilute o/w microemulsion composition containing, by weight, 1% to 10% of an anionic detergent, 2% to 10% of cosurfactant, 0.4% to 10% of perfume and the balance water or a concentrated microemulsion composition containing, by weight 18% to 65% of anionic and nonionic detergent, 2% to 30% of cosurfactant, 10% to 50% of perfume and the balance water which upon dilution with water will yield said dilute o/w microemulsion composition.Type: GrantFiled: August 14, 1987Date of Patent: January 21, 1992Assignee: Colgate-Palmolive CompanyInventors: Myriam Loth, Claude Blanvalet, Baudouin Valange

Patent number: 5076954Abstract: A stable microemulsion cleaning composition is described, which, in the absence of opacifying component, appears clear to the eye, and which is especially useful for cleaning surfaces having oily or greasy soils thereon, which comprises synthetic organic detergent, water, co-surfactant of the described type, and perfume, which is the only "solvent". The concentrated detergent composition may be employed as is, or may be easily diluted with water to form a similarly clear and stable microemulsion. In process aspects of the invention both the concentrated and the diluted compositions may be employed to remove oily and greasy stains from substrates, such as normally shiny bathroom fixture and floor and wall surfaces, including tiles, by a "spray and wipe" process, which leaves the surface shiny. When the invented compositions are acidic they are useful for removing lime scale and soap scum from hard surfaces.Also described are processed for manufacturing and diluting the invented compositions.Type: GrantFiled: November 12, 1987Date of Patent: December 31, 1991Assignee: Colgate-Palmolive CompanyInventors: Myriam Loth, Claude Blanvalet, Baudouin Valange

Preferably a phophoric acid is present to further improve protection of such European enamel surfaces.Type: GrantFiled: September 7, 1989Date of Patent: August 13, 1991Assignee: Colgate-Palmolive CompanyInventors: Michel Thomas, Genevieve Blandiaux, Baudouin Valange
