Patent application numberDescriptionPublished
20090042764Cleaning Agent Comprising Complexes with Bleach Catalytic Activity - Hard surface cleaning agents comprising a macrocyclic compound of the general formula L:02-12-2009
20100154832CLEANING PROCESS - Process for cleaning dishes in a dishwasher during which the aqueous washing liquor contained in the interior of the dishwasher is at least partly removed from the interior of the dishwasher at a point in time t. The process involves metering a dishwasher detergent A containing one or more surfactants and one or more anionic polymers at a time t1t in an amount m2 into the interior of the dishwasher. The process according to the invention differs from conventional cleaning processes in that formation of deposits is reduced and drying efficiency improved.06-24-2010
20100160204Detergents - Dishwasher detergents containing: a) 10 to 60 percent by weight of a builder; and b) non-ionic surfactant of the general formula06-24-2010
20100163076Method for Machine-Washing Dishes - Method for machine-washing dishes comprising at least one wash or rinse cycle wherein the dishes are washed in each wash or rinse cycle with an aqueous washing liquor that, for multiple wash or rinse cycles, is at least partially replaced between wash or rinse cycles, wherein 07-01-2010
20100216683Cleaning Product - Liquid, aqueous washing or cleaning product formulation, comprising a) at least one washing- or cleaning-active enzyme; b) 1,2-propylene glycol; and c) nonionic surfactant of the general formula R08-26-2010
20100222247Cleaning Agent - Liquid, low-alkaline and bleach-free dishwasher detergent having a pH value (20° C.) of 8 to 12 and containing: a) 10 to 60 percent by weight of a builder; b) more than 1.5 percent by weight of a phosphonate; c) 0.1 to 20 percent by weight of an anionic copolymer comprising: i) unsaturated carboxylic acid(s) and ii) sulfonic acid group-containing monomer(s). Detergents according to the invention exhibit a good cleaning power on bleachable dirt, particularly tea stains.09-02-2010
20100249007Cleaning Agents - Two-phase or multi-phase washing or cleaning agent comprising a) a bleaching agent, b) a bleach activator, c) a bleach catalyst selected from the group of bleach intensifying transition metal salts and transition metal complexes, wherein bleaching agent a) is present together with at least one of the components b) and c) in a phase of the washing or cleaning agent, the agent having improved cleaning performance, particularly for bleachable stains.09-30-2010
20100249009Cleaning Agents - Two- or multi-phase detergents or cleaning agents which comprise a) a bleaching agent, b) a bleach activator, c) a bleach catalyst, selected from the group of bleach boosting transition metal salts and transition metal complexes, the bleaching agent a) being present in a separate phase of the detergents or cleaning agents separate from components b) and c). The detergents or cleaning agents according to the invention are characterized in that the bleach activator b) is used in particulate form and the bleach activator particles comprise, based on their total weight, a percentage in bleach activator of more than 80% by weight. The detergents or cleaning agents according to the invention have a good cleaning power on bleachable soilings.09-30-2010
