  • Patent number: 9187720
    Abstract: The invention relates to the use of a sanitary product in piece form for use in the cistern of a toilet, which product comprises at least two different gel formers (1, 2) and fragrances, wherein one gel former (gel former 1) forms gels with hydrophobic liquids, which gels are insoluble or scarcely soluble in water, and the other gel former (gel former 2) is water-soluble or water-dispersible and wherein the product is transparent, gradually flushes away and releases fragrances, and gel formers 1 and 2 are in one phase.

  • Patent number: 9102906
    Abstract: The invention relates to a sanitary composition for cleaning and/or disinfecting and/or for fragrance release, which composition is applicable directly to the sanitary unit, adheres there and can be rinsed off only after a relatively large number of rinse operations, and which composition comprises surfactants and at least one adhesion promoter, said adhesion promoter being an oxo acid of the following formula and R being an alkyl or aryl radical, R? is an alkyl or hydroxyalkyl group, R? is an alkyl, aryl or alkoxyalkyl radical, X a main group element of main groups 5 or 7 from the 3rd period, selenium, tellurium, or a transition group element, m=1 to 50, n=0, 1, 2, q=1, 2, r=0, 1 and p=1, 2, and the viscosity of the composition, measured with a Haake viscometer, plate-cone system, PK 5 1° sensor, shear rate of 25 s?1 and 20° C., is at least 15 000 mPas.

  • Patent number: 8835371
    Abstract: An agent for the sanitary sector, which agent can be applied directly on a sanitary object, adheres there and can be flushed away only after a relatively large number of flushing operations. The agent includes fillers from the group of surfactants and also an adhesion promoter. The adhesion promoter is selected from hydrogenated polystyrene derivatives and olefin homopolymers and copolymers of two or more olefins, where the olefin homopolymers and copolymers may also be partially hydrogenated. The viscosity of the agent is at least 30 Pas, measured using a Haake viscometer, plate/plate system, plate diameter 10 mm, at a shear gradient of 2.62 s?1 and 20° C. The agent is so sticky that it can serve to attach bar-shaped agents in the toilet bowl. The concentration of the surfactants in the case of an adhesion promoter from the group of polyalkyleneimines is between 7 and 60% by weight.

  • Patent number: 8444771
    Abstract: Method for cleaning and/or deodorizing a toilet bowl or urinal. In one embodiment, the method involves directly applying an agent to the toilet bowl or urinal. The agent adheres to the toilet bowl or urinal and can be flushed away only after a relatively large number of flushing operations. The agent includes fillers from the group of surfactants and also an adhesion promoter. The viscosity of the agent is at least 30 Pas, measured using a Haake viscometer, plate/plate system, plate diameter 10 mm, at a shear gradient of 2.62 s?1 and 20° C. and the agent is so sticky that it can serve to attach bar-shaped agents to the toilet bowl or urinal, wherein the concentration of the surfactants in the case of an adhesion promoter from the group of polvalkyleneimines is between 7 and 60% by weight. The agent may have associated with it one or more bar-shaped compositions.

  • Patent number: 6667286
    Abstract: The invention relates to a sanitary agent for cleaning and/or disinfecting and/or releasing an odorant, said agent comprising an adhesion promoter, water anionic and/or non-ionic and/or amphoteric surface active agents and, optionally, further common constituents such as odorants, thickeners, colorants and preservatives. The adhesion promoter is selected from the group of very long or long-chained organic molecules which are hydrophilic at least in part. The hydrophilic part of the adhesion promoter interacts at least in part with the water molecules in the presence of water and becomes “sticky” so that the agent can be applied directly on the sanitary object in the presence of small amounts of water and can adhere thereto. The viscosity of the agent is of at least 15,000 mPas and the product can only be washed away completely after numerous rinsings.
