Definitions

  • the present invention relates to a piece-shaped cleaning and Beduftungssch for the sanitary sector, especially for toilets.
  • rim blocks which are fastened in a container, in particular a basket or cage-like container, on the rim ("rim") of the toilet.
  • the agent in the container is covered by the rinse water during each rinse.
  • a small proportion of Rimblocks is dissolved with the release of surfactants, fragrances, etc., with each rinse, which then the desired cleaning of the toilet bowl and toilet sump and the desired scenting is achieved.
  • the known Rimblocks consume only by the purge flow of water, and the fragrance release is dependent on the flushing of the toilet.
  • the room scenting is at the Rimblocks in Substantially achieved in that the fragrances are flushed out by the rinse water, get into the toilet sump and evaporated some of the fragrances in the toilet sump. If the known Rimblocks thus used in a less frequented toilet, so although the desired cleaning is achieved after using the toilet, but not the desired persistent Jardinbeduftung is guaranteed as a result of too low flush numbers.
  • piece-shaped toilet cleaners which comprise gelling agents, solvents and fragrances and which allow with low doses of fragrance sufficient and permanent room fragrance even if no toilet flushing takes place.
  • a toilet cleaner comprising both a detergent tablet phase and a gel phase with a perfume is disclosed in U.S. Pat EP 1 418 225 B1 known. With this agent, both the desired cleaning effect is achieved, and even with low perfume dosing a sufficient and permanent room scenting allows even if no toilet flushing takes place.
  • An agent with a gel phase and a detergent tablet phase is also known from the EP 1 553 162 B1 known, wherein the gel phase is formed in this case of a polyamide resin.
  • the object of the present invention is to provide a means that counteracts the habituation effect with good cleaning performance and scenting.
  • an agent comprising at least two phases, the first phase having a phase with a first perfume and a solvent content of at least 5% and the second phase is a detergent tablet phase comprising at least 10% surfactants and a second perfume and the first and second perfumes are different from each other.
  • the first phase of the agent which comprises solvents and a first fragrance
  • the release of the first fragrance from the first phase is carried out in the required amount by evaporation from the first phase, rinsing is not required for this purpose.
  • the first phase has a defined evaporation profile, i. it is evaporated per unit time about the same amount of the first fragrance in the room.
  • the first phase may also be consumed when rinsing with water. However, this is not required for the present invention.
  • the second phase the detergent tablet phase, which serves for cleaning and therefore comprises surfactants, also has a perfume, namely a perfume, which is inventively different from the first perfume.
  • the second perfume from the detergent tablet phase is essentially released by rinsing with water.
  • a small proportion of the second fragrance also evaporates without overflowing the second phase with water in the room.
  • the perfume B for example, limes released.
  • the first fragrance from the first phase continues to evaporate into the room - without further rinsing - so that the odor gradually returns to the first fragrance, e.g. Lavender, because the first fragrance (without rinse) from the first phase generally evaporates more vigorously than the second fragrance from the second phase (without rinse).
  • the first fragrance e.g. Lavender
  • the first phase forms part of the surface of the agent.
  • the detergent tablet phase by the rinsing yes the second fragrance is released, forms another part of the surface of the agent.
  • a sudden change in scenting takes place in the inventive agent - as already explained - from the basic scenting prior to rinsing to the scent generated by the scenting process by the second fragrance.
  • the rinsing off of the agent successively changes the basic scenting, which consists of the respective "first scenting of the first phase" without over-rinsing with water and the generally weaker "second scent scenting".
  • the change in the "basic scenting" with time presupposes that the dissolution rate of the first and second phases in water is different.
  • Substantial scenting taken into account by the first phase is achieved when the rate of dissolution of the first phase when rinsing with water is significantly lower than that of the second phase.
  • the detergent tablet dissolves faster than the first phase per unit time and that the proportion of detergent tablet phase is generally greater than that of the first phase, the base fragrance by the first fragrance in the first phase and also by a constant evaporation of the second perfume from the (present in larger quantities) detergent tablet phase.
  • the odor of the first fragrance in the base fragrance gradually increases.
  • the base scent is almost exclusively based on the first fragrance.
  • This example shows that the means according to the invention not only sets a new fragrance pulse during rinsing, but also that the basic fragrance of the preparation (without rinsing) also changes over time.
  • the type, intensity and change of the basic scent over the life of the composition depends on the proportions in which the first and the second phase are contained in the composition, how the evaporation or rinsing geometry or their ratio in the composition is, which concentrations the first and second perfume contained in the agent, which fragrances are selected and whether the evaporation of the perfume is optionally hindered by further additives.
  • the flushing rates and the rinsing behavior of the first and second phases can be adjusted by the addition of rinsing regulators or water repellents.
  • inventive step may be supplemented with other phases having the same or different characteristics.

  • the gel phase 13 is located in two elongated U-shaped recesses whose leg length is about 0.7 cm and the base area is about 0.5 cm.
  • the agent has on its surface the first phase from which the first fragrance (fragrance A) permanently evaporates.
  • the proportion of the surface of the first phase to the total surface of the agent is low, that is, during rinsing, the cleaning agent molding phase is predominantly rinsed off and at each rinsing process a portion of the second fragrance rinsed in the detergent tablet phase and released for the fragrance pulse (perfume B).
  • composition of the invention based on a transparent gel phase as the first phase and a detergent tablet phase as a second phase.
  • Nonionic surfactants 20 60 Polyoxyethylene 10 / C9-C11 alcohol; Polyoxyethylene 11 / C13-C15 alcohol 50 Anionic surfactants 10 - 25 Sodium dodecyl sulfonate, toluenesulfonate, dibenzoylsulfonate sodium salt 17 gelling agent 3 - 15 Sodium stearate sprayed sodium myristate, sodium laurate 5 solvent 30 - 70 Water, 1,2-propanediol ad 100 dye 0 -1 0.01 Perfume A 5-40 lavender 33

  • the preparation of the composition according to the invention was carried out such that the components of the second phase were extruded into a block with the dimensions of about 6.2 x 3.0 x 2.0 cm with two U-shaped recesses and after cooling the liquid gel mass in the two recesses were filled.
  • the produced product consists of 92% of the second and 8% of the first phase.
  • Agent was hung in a toilet bowl below the edge of the toilet and determines the Abteil by hanging after determining the mass of the agent this in the test toilet, the agent after x-rinses taken out of the toilet again and then the residual weight of the detergent tablet and the residual weight of the gel was determined.
  • test results are listed in the following table: ⁇ u> Table 1 ⁇ / u> Spüliere Mass second phase (detergent form-body phase) [g] Mass first phase gel [g] Sum 1st and 2nd phase 0 46 4 50 43 37.8 3.92 41.72 80 34.74 3.66 38.4 114 26.378 3,918 30.296 243 8,361 2,073 10.434 280 3,157 2,434 5,591
  • the detergent tablet phase consumes heavily during rinsing. After about 100 rinses, the mass of the detergent tablet phase has already decreased to about half, whereas the gel phase has decreased after about 100 rinses only about 10 to 20%.
  • the percentage contribution of fragrance from the first phase and the second phase is in the FIG. 4 shown.
  • the scent is 60% from the gel phase and 40% from the detergent tablet phase.
