Definitions

  • the present invention relates to an aqueous cleaning agent for the sanitary sector, in particular for toilets and urinals, and a method for its production. Furthermore, the invention relates to a receiving device for the cleaning agent according to the invention and its use, in particular for the cleaning of toilets and urinals and for perfume delivery.
  • Detergents for the sanitary sector form one of the main groups in the market of cleaning and cleaning agents and are available in a wide variety of compositions and embodiments.
  • the prevention of unpleasant odors is in the foreground. These arise especially where on hard surfaces unsightly deposits, such as lime, waterstone and urine stone, form, which not only form a breeding ground for bacteria, but can also lead to unpleasant odors. Therefore, a primary function of sanitary ware, besides its cleansing and disinfecting function, is the delivery of perfumes, preferably over an extended period of time. To ensure this, it is necessary for the cleaning agent to remain in the sanitary appliance for a certain time and not to be washed off again with the first rinsing process.
  • One approach to achieve a certain residence time of the cleaning agent in the sanitary device is to provide the detergent in the form of a gel or a paste, which adheres to the surface of the sanitary device, such as the inner wall of a toilet bowl, and only after repeated rinsing and after dissolving.
  • EP 1 318 191 describes a paste for perfume delivery in particular for the sanitary area, which is directly applied to the sanitary object, there adheres and dissolves only after a large number of rinses, wherein the paste is a primer from the group of oligo- and / or polyethylene oxide and / or oligo and / or polypropylene oxide and / or oligo- and / or polybutylene oxide comprising block copolymers and the aryl ethoxylates or alkyl-aryl ethoxylates, as well as perfume and water.
  • EP 1 086 199 discloses a sanitary agent which adheres directly to the sanitary article and which comprises adhesion promoters in addition to anionic surfactants, nonionic surfactants or amphoteric surfactants, wherein the sanitary agent has a viscosity of at least 15,000 mPas.
  • EP 1 325 103 describes a sanitary agent which, in addition to water and anionic and / or nonionic and / or amphoteric surfactants and adhesion promoters, either at least one from the group of glycerol, 1,3-dihydroxypropane, 1,3- or 1,4-dihydroxybutane, 1, 3-dihydroxyisobutane and pentaerythritol selected compound or between 1 and 20 wt .-% of an aliphatic di-, oligo- or polyhydroxy compound or their ethers.
  • EP 2 275 524 is concerned with an agent for the sanitary sector, which contains fillers from the group of surfactants and a coupling agent, wherein the coupling agent is selected from the group of hydrogenated polystyrene derivatives, the olefin homopolymers and the copolymers of two or more olefins and wherein the agent has a viscosity of has at least 30 Pas and is so sticky that it can serve for the attachment of piece-like means in the toilet bowl.
  • the coupling agent is selected from the group of hydrogenated polystyrene derivatives, the olefin homopolymers and the copolymers of two or more olefins and wherein the agent has a viscosity of has at least 30 Pas and is so sticky that it can serve for the attachment of piece-like means in the toilet bowl.
  • DE 10 2013 108 019 relates to an agent for the sanitary sector, which contains at least 25 wt .-% surfactants and 25 wt .-% of a hydrophobic compound, wherein the hydrophobic compound is selected from the group of natural or mineral oils, petrolatum, oils, fats or waxes, also partially hydrogenated , Silicone oils and nonpolar solvents and the viscosity of the agent is at least 30 Pas.
  • Conventional cleaning agents in particular liquid, also have the disadvantage that they do not dwell on the surface to be cleaned, but are already rinsed and rinsed out after a rinsing process. Therefore, a new application of the cleaning agent is necessary for each cleaning and / or disinfection step, which leads in particular to daily cleaning, for example in public institutions, to a high consumption and corresponding economic and ecological burden.
  • Detergents which are in the form of a gel are known from the prior art.
