Definitions

  • the invention relates to a method for sanitary cleaning with a sanitary cleaner in liquid or solid form with a content of germ-inhibiting organic substances, with conventional lime-dissolving water-soluble acids and optionally with other additives as well as a sanitary cleaner for carrying out this method.
  • Usual sanitary cleaners contain water-soluble acids for dissolving limescale or urine scale and regularly a surfactant, which must be essentially biodegradable according to legal regulations, but often leaves a non-degradable residue after use.
  • Suitable water-soluble acids are, for example, organic acids, such as carboxylic acids with 2 to 3 carbon atoms, dicarboxylic acids with 3 to 8 carbon atoms, hydroxycarboxylic acids with 1 to 6 carbon atoms, 1 to 5 hydroxyl groups and 1 to 3 carboxyl groups or mixtures thereof. These acids are among others described in DE-OS 32 35 159.
  • DE-PS 26 18 930 shows suitable germ-inhibiting substances, such as paradichlorobenzene. Other chlorinated or halogenated aliphatic and aromatic hydrocarbons are known for the same purpose.
  • DE-OS 35 38 131 describes a solution process and solvent for poorly soluble carbonates, in which a Lewis acid and a medium to weak acid are used in a ratio of 1: 1 to 6: 1.
  • the agent preferably contains metal ions which correspond to the material on which the scale is deposited.
  • the agent preferably consists of solid acids, for example citric or oxalic acid, and a solid Lewis acid, for example aluminum or iron (II) chloride hydrate.
  • the sanitary cleaner shown in DE-OS 25 32532 only works in the first phase of the application, for example in a toilet bowl. Its effect does not extend to the second phase. It is available in tablet form and is mainly used to remove lime residues, with citric acid being considered as a lime.
  • the invention was therefore based on the object of developing the method described at the outset such that on the one hand the desirable germ-inhibiting function is developed in the first phase of action, for example in a toilet bowl, but on the other hand the degradation of the microflora of the waste water (in the second phase of action) is not is disturbed, and to propose a particularly suitable sanitary cleaner for performing this method.
  • the sanitary cleaner contains germ-inhibiting organic substances in such a concentration that their concentration in the action phase in the sanitary device to be treated is at least about twice and at most about 200 times the minimum inhibitory concentration (MIC) , and one uses against the lime-dissolving water-soluble acid-promoting organic substances in such a concentration in the sanitary cleaner that after dilution or rinsing the germs which degrade the organic substance of the water are promoted in their effect.
  • MIC minimum inhibitory concentration
  • the invention further relates to a sanitary cleaner for carrying out this method, which is characterized in that it contains germ-inhibiting organic substances in an amount of 0.5 to 150 g / kg, in particular in an amount of 1 to 80 g / kg, and against the lime-dissolving water-soluble acid contains resistant germ-promoting organic substances in an amount of 10 to 1000 mg / kg sanitary cleaner.
  • the sanitary cleaner according to the invention can be used in a wide range of applications, for example in the entire sanitary cleaning area, such as in particular in toilet bowls, urine bowls, bathtubs, bidets, wash basins and shower trays. This list of areas of application is not exhaustive.
  • germ-inhibiting and germ-promoting organic substances are used at the same time, which was not previously thought possible.
  • the germ-inhibiting and germ-promoting organic substances have certain things in common. So they are resistant to organic acids and their salts.
  • Suitable germ-inhibiting organic substances are in particular acidic organic substances or their salts or suitable derivatives and essential oils. Those germ-inhibiting organic substances that occur in nature are preferred.
  • the acidic organic substances mentioned are, in particular, aromatic, aliphatic, alicyclic and / or heterocyclic carboxylic acids or their salts, in particular in the form of the alkali metal or alkaline earth metal salts, or else suitable derivatives thereof.
  • the acidic organic substances should be used to develop the desirable germ inhibition be water-soluble.
  • the carboxylic acid itself may be water-insoluble, but the suitable salt thereof may be water-soluble and suitable.
  • the particularly suitable aliphatic carboxylic acids include, in particular, lower carboxylic acids with 1 to 7 carbon atoms, such as in particular formic acid, acetic acid, propionic acid, caproic acid, malonic acid and oxalic acid, and also various fatty acids with 8 to 12 carbon atoms, e.g. Undecenoic acid, provided that they can be used in the form of suitable water-soluble salts.
  • Fatty acids with more than 12 carbon atoms are generally not suitable because they are not themselves water-soluble and, moreover, the majority of their salts also do not meet the requirement for water solubility.
  • the butyric acid which is assigned to the lower fatty acids, is not recommended due to its unpleasant smell.
  • Suitable derivatives of the above carboxylic acids are hydroxy acids, such as glycolic acid and white acid, and oxo acids, such as acetoacetic acid and pyruvic acid.
  • Water-soluble aromatic carboxylic acids are also particularly suitable, such as, in particular, benzoic acid, salicylic acid and also phenol carboxylic acids.
  • Essential oils are also of particular advantage.
  • Essential microbicidal oils are in particular: thyme oil, citrus peel oils, eucalyptus oils, origanum oil, rosemary oil, cinnamon oil, alum oil, camphor oil, conifer oil and fennel oil.
  • the thyme oil is particularly preferred here.
  • the active ingredients contained therein can also be used in their place.
  • Examples of essential oils that inhibit germs are: Thymol., Carvacrol, Therpineol, Ciniol and Fenchorx.
  • the essential oils are water-insoluble, but just like the water-insoluble vitamins, they can be used with suitable, especially environmentally friendly emulsifiers or solubilizers as germ-inhibiting substances in sanitary cleaners.
  • solubilizers for the group of substances described above.
  • the selection of the most suitable solubilizers for aqueous systems takes place according to the HLB system and must be determined experimentally for each individual essential oil aqueous systems are particularly suitable as solubilizers with HLB values from 12 to 18.
  • solubilizers are particularly suitable which are described in Römpps Chemie-Lexikon, 8th ed., vol. 3, p. 2399.
  • Non-ionic emulsifiers or solubilizers fruit acid esters of the mono-di-glycerides, e.g. Citric acid esters, polyoxyethylene glycerol fatty acid esters, e.g. Polyoxyethylene glycerol mono laurate with 30 mol AO.
  • an organic acid can be lime-dissolving on the one hand and also have a germ-inhibiting effect.
  • the germ-inhibiting organic substances in the sanitary cleaner according to the invention are preferably in an amount of 0.5 to 150 g / kg sanitary cleaner, in particular in an amount of 1 to 80 g / kg Sanitary cleaner and very particularly preferably in an amount of about 2 to 7 g / kg ö w sanitary cleaner before.
  • the concentration of the germ-inhibiting organic substances in the first phase of action must be adjusted in such a way that their concentration in or in the basin to be treated is at least about twice and at most about 200 times the qc
  • Minimum inhibitory concentration is. It is preferred that the concentration of the germ-inhibiting organic substances in the active phase is at least about double and is at most about 50 times, in particular about 30 times the minimum inhibitory concentration.
  • amino acids and / or orotic acid or suitable salts or derivatives thereof as well as vitamins are used as germ-promoting organic substances.
  • the derivatization mentioned must not go so far as to impair the desired effect of promoting germs.
  • Particularly suitable amino acids are: alanine, arginine, asparagine, aspartic acid, cysteine, cystine, glutamine, glutamic acid, glycine, histidine, hydroxyproline, isoleucine, leucine, lysine, methionine, ornithine, phenylalanine, proline, serine, threonine, tryptophin, tyrosine .

  • the invention it is possible to achieve hygienic cleaning of sanitary facilities without interfering with the microbial degradation of the organic substances in the waste water.
  • These apparently contradictory properties could surprisingly be achieved by introducing the described germ-inhibiting or germ-killing active ingredients into the sanitary cleaner according to the invention in such a concentration that their concentration during use in the intended action phase, for example in the toilet bowl, is above the minimum inhibitory concentration (MIC) ) lies.
  • MIC minimum inhibitory concentration
  • the "minimal inhibitory concentration" is a common technical term.
  • the germ-promoting organic substances are introduced into the product in such a concentration or quantity that, after the usual dilution of the medium in the first phase of action, they exert a growth-promoting effect on the microorganisms when they enter the wastewater.
  • the sanitary cleaner according to the invention When using the sanitary cleaner according to the invention, which can be, for example, in powdery, granulated form or in aqueous form, it becomes little in the toilet bowl, for example Diluted water. There, the active hygiene substances have a germ-inhibiting or germicidal effect, while the germ-promoting substances are initially ineffective. After flushing the toilet bowl following the action of the sanitary cleaner, the germ-inhibiting organic substances are reduced in their concentration below the MIC value and thus become ineffective.
  • the concentration of the germ-promoting organic substances in the sanitary cleaner according to the invention is such that they promote the activity of the wastewater germs, which degrade the organic substance, even after rinsing or a strong dilution and thus accelerate or at least do not disturb the biological wastewater treatment.
  • the amount of germ-promoting organic substances in the sanitary cleaner according to the invention is not critical. It must be tested in each individual case which minimum concentration of the germ-promoting organic substance used is sufficient. As a quantitative guideline, about 10 to 1000 mg of germicidal organic matter per kg of sanitary cleaner could be given, the range of about 100 to 800 mg / kg being preferred.

  • the particular advantages of the sanitary cleaner according to the invention are as follows: it fulfills the essential requirements for an optimal toilet cleaner with regard to cleanliness (removal of faeces and dirt residues, limescale deposits and urine scale). It leads to a noticeable reduction in environmental pollution because its disinfectant effect can be attributed to degradable natural substances, i.e. it can be the calcareous water-soluble acid, the germ-inhibiting organic substances as well as the germ-promoting organic substances of natural origin.
