Definitions

  • the present application relates to aqueous, gelatinous preparations which contain certain emulsifiers and optionally further ingredients, and which are distinguished by their particular rheological properties, and to the use of such agents as cleaning agents, in particular for sanitary cleaning.
  • Sanitary cleaners are generally understood to mean special cleaners which are intended to remove deposits of lime and, if appropriate, urine stones in the sanitary area, in particular in toilets (cf. Römpp, Chemie Lexikon, 9th edition, 1992, p. 3988 ). Furthermore, such agents often still contain fragrances to mask the typical odors of sanitary facilities, or to give the user an impression of freshness and cleanliness.
  • Sanitary cleaners therefore contain conventional water-soluble acid for dissolving limescale or urine scale and regularly a surfactant that must be substantially biodegradable according to the legal requirements, but often leaves a non-degradable residue after use.
  • Suitable water-soluble acids are, for example, organic acids such as carboxylic acids having 2 to 3 carbon atoms, dicarboxylic acids having 3 to 8 carbon atoms, hydroxycarboxylic acids having 1 to 6 carbon atoms, 1 to 5 hydroxyl groups and 1 to 3 carboxyl groups or mixtures thereof.
  • the sanitary cleaners are flushed into the sewer system, where they may act toxic to the local microflora, thereby delaying the degradation of the biomass in the wastewater.
  • the known sanitary cleaner are increasingly critically assessed because of the aforementioned toxic effect on the microorganisms of the wastewater and the pollution of the wastewater and groundwater with incompletely degradable substances or with further questionable degradation materials.
  • sanitary agents which are also referred to here as Sanitärreiruger, which should show less of a cleaning rather than a deodorizing effect, and accordingly on a higher proportion of perfumes feature.
  • These agents are placed, for example, in the toilet to deliver perfumes there continuously or only on contact with water.
  • Sanitary cleaners are usually offered in the form of solid blocks, or as a liquid formulation which is applied directly to the surface of the sanitary facilities - preferably a toilet - or which is used with the aid of a metering device (for example a so-called "toilet bowl”).
  • the solid or liquid sanitary cleaner is introduced into the metering device, wherein this metering device is then positioned so that it comes into contact with the flushing water of the toilet so that the cleaner is gradually washed out of the metering device and then in the form of a dilute aqueous Solution can unfold its effect.
  • such forms are available in which the sanitary cleaner is made up in the form of a viscous gel.

  • gels are not only viscous but also show elastic properties.
  • the gels according to the claimed embodiment are so-called "hum gels", since in a suitable vessel they are capable of producing, with external excitation, a frequency of oscillation which can be perceived by the human ear. This is due to the particular elastic properties of the gels according to the invention.
  • Brumm gels are in the Römpp Chemielexikon, online edition, version 3.5 dated 27.07.2009 characterized as follows: Optically isotropic, transparent gels which, due to their energy elasticity, can be stimulated by mechanical shocks to produce vibrations in the audible frequency range. This property was first found in special surfactant systems consisting of surfactants, hydrocarbons and water, so-called microemulsion gels (see microemulsion).
  • the audible tone ranges from a low hum to a high metallic sound and depends on the gel itself, the size and geometry of the vessel in which the sample is located, and the fill level.
  • the time constant at which the oscillation decays is in the range of one second for most samples.
  • hum gels are known and are based for example on amphoteric surfactants and selected ethylene oxide / propylene oxide copolymers in the US 3925241 described. It is noteworthy that only when certain surfactants or thickeners are selected in selected amounts with each other, the gels can be characterized as hum-gels.
  • Brummgelen For rheological description of Brummgelen usually the gel is mixed by a mechanical pulse into vibrations of different frequency (eg between 1-100 s -1 ) and then determines the resonance curve of the gel. In the present case, this is done in a commercially available rheometer with plate-plate measurement geometry (see below). In the FIG. 1 is a resonance curve for an inventive Brummgel listed.

They are easily self-adhesive and do not dissolve too quickly on contact with, in particular, cold water (temperature ⁇ 20 ° C and especially ⁇ 14 ° C).
  • the preparation was carried out by preparing a mixture of the ingredients without the perfume at room temperature. Thereafter, the mixture was heated. The water was brought to about 85 ° C and then the perfume is cold weighed into the hot mixture and stirred. Thereafter, the water was added warm and also stirred.
  • a rinsing test was carried out as follows: Approx. 5g of the sample was spread on a tile and painted into a uniform lump. A water hose was attached to a tripod and narrowed with a pinch cock to increase the power of the jet. The water jet (temperature of the water about 18 to 20 ° C) was set so that it comes up just over the point, the faucet was opened by about 90 °. The time was then measured until the gel sample was rinsed off.
