Definitions

  • Sanitary agents in solid gel form are known from the prior art. Such are used, for example, as self-adhesive sanitary products. These self-adhesive sanitary products are suitable to adhere to surfaces independently, i.e. without further aids.
  • toilet blocks which have a self-adhesive composition are known from the prior art. Such toilet blocks can be attached to the wall of the toilet bowl without a basket and adhere to it automatically even after a number of flushing processes.
  • the publication EP 1 086 199 B1 describes a self-adhesive sanitary agent in the form of a gel which adheres independently to the surfaces of objects that are usually used in sanitary areas, such as toilet bowls, and is only rinsed off the toilet surface after several flushes.
  • Self-adhesive gel compositions are also referred to as solid gel compositions. They differ from flowable gel compositions in that they adhere independently to carrier materials, for example the toilet bowl. In this context, self-adhesive means in particular that the gels are rinsed off the toilet bowl only after a large number of flushes.
  • carrier materials for example the toilet bowl.
  • self-adhesive means in particular that the gels are rinsed off the toilet bowl only after a large number of flushes.
  • self-adhesive gel is sufficiently known to the person skilled in the art. Reference is made, for example, to EP 1086199 B1.
  • the gel-like cleaning and fragrance products known from the prior art sometimes only have an unsatisfactory consistency, it being observed that the gel changes in an undesirable manner with loss or absorption of water. It was also found that the foaming behavior of the known gel compositions based on fatty alcohol ethoxylates is unsatisfactory. In particular, these compositions have no long-lasting foam formation or foam stability.
  • One object of the present invention is to propose a gel-like cleaning and fragrance product which has a stable consistency with good rinsing behavior and at the same time has good initial foam formation (“flash foam”) and, moreover, long-lasting foam stability.
  • This object is achieved by providing a sanitary cleaning agent comprising a fragrance; at least one anionic surfactant; a mixed alkoxylated block copolymer; and furthermore at least one additive selected from the group consisting of inorganic salts, polyols and monosugars and / or sugar alcohols.
  • a cubic phase means that spherical polymer micelles are arranged in a cubic lattice.
  • a structural condition for this is that the packing parameter of the polymer still allows the formation of spherical micelles even at high concentrations.
  • the mixed alkoxylated block copolymer has hydrophilic parts and hydrophobic parts and is ideally suited for the formation of a stable cubic phase. It has been found that, in particular, the foam stability of the mixed alkoxylated block copolymer is superior to the foaming behavior of gel-like sanitary cleaning agents based on fatty alcohol ethoxylates.
  • the gels according to the invention are also distinguished by a high level of stability or “robustness” with respect to water absorption or water release.
  • the equilibrium air humidity i.e. the air humidity at which an openly stored product according to the invention neither absorbs nor loses water from the air, is e.g. 74% at 25 ° C.
  • Below this air humidity the product loses a little water, e.g. 10% of its weight within 40 days. Due to the phase behavior, one does not leave the cubic phase and the theological properties change only insignificantly.
  • the sensitivity to water absorption results from how far the respective composition is from the phase boundary.
  • a formulation can easily be found which can absorb 10, 20, 30% water without leaving the cubic phase.
  • Surfactants serve to improve the cleaning effect and the foam behavior of the formulations according to the invention, in particular the initial foam (“flash foam”). Since polymer amphiphiles can produce a stable foam, but because of their slow speed The use of low-molecular surfactants is advantageous here to create only a small amount of “flash foam” diffusion to the surface.
  • anionic surfactants exhibit particularly advantageous foam formation characteristics.
  • a stable “flash foam” can preferably be generated using anionic surfactants.
  • the cleaning agent therefore has at least one anionic surfactant.
  • the addition of the anionic surfactant significantly reduces the stability of the cubic phases and thus also the “robustness” of the composition and worsens its rinsing behavior.
  • the area of existence of the cubic phase in the phase diagram is reduced, i.e. the addition of anionic surfactant will convert the gel-like cubic phase into a flowable, isotropic, micellar phase under application conditions, which no longer meets the application requirements.
  • anionic surfactants reliably enable excellent “flash foam” formation, but the presence of the negative head groups and the resulting repulsive electrostatic Coulomb interactions destabilize the cubic phase formed by the mixed alkoxylated polymer.
  • the cubic phase of the sanitary cleaning agent destabilized by the anionic surfactant can be stabilized by at least one additive selected from the group consisting of inorganic salts, polyols and monosugars and / or sugar alcohols even in the presence of a surfactant.
  • the present invention is based on this knowledge.
  • Possibilities of determining the presence of a cubic phase in particular rheological measurements and scatter measurements, e.g. SAXS (Small Angle X-Ray Scattering), are known to the person skilled in the art at the time of priority.
  • SAXS Small Angle X-Ray Scattering
  • a “surfactant” is preferably a low molecular weight surfactant such as are known to those skilled in the field of cleaning agents.
  • polymers are not considered to be surfactants.
  • An anionic surfactant for the purposes of the invention is accordingly a low molecular weight surfactant, as is known to those skilled in the field of cleaning agents, with a negative overall charge.

  • the mixed block copolymer is further preferably a block copolymer which has a first terminal block which is formed from several alkoxy units of a first type, preferably ethoxy units, and a second central block which is formed from several alkoxy units of a second type, preferably from several propoxy units , and has a third terminal block which is preferably formed from several alkoxy units of the first type, preferably ethoxy units.
