Definitions

  • the invention relates to a sanitary cleaner in liquid or solid form with a content of germ-inhibiting organic substances, conventional lime-dissolving water-soluble acids and, if appropriate, other additives and the use thereof.
  • Usual sanitary cleaners contain water-soluble acids for dissolving limescale or urine scale and regularly a surfactant that must be essentially biodegradable according to the 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 well-known sanitary cleaners are used because of the toxic effect on the microorganisms of the wastewater and the pollution of wastewater with questionable degradation materials increasingly critically assessed.
  • the processes and products mentioned cannot be called environmentally friendly.
  • the sanitary cleaner shown in DE-OS 25 32 532 only works in the first phase of action, for example in a toilet bowl. Its effect does not extend to the second phase. It is in tablet form and is mainly used to remove limescale residues, with citric acid as a descaling agent.
  • WO-A-90/11013 which has not been previously published, describes a phytosanitary agent which (I) contains at least two amino acids and / or natural carboxylic acids or their derivatives or salts, (II) purines and / or pyrimidines or their derivatives and (III) Contains vitamins or derivatives or precursors thereof, with about 0.001 to 1 part by weight of a single compound of group (II) and about 0.001 to 1 to about 0.1 to 10 parts by weight of a single compound of group (I) Part by weight of a single compound of group (III) is eliminated.
  • This agent is used to prevent and control plant diseases of biotic origin and to increase and secure the yield of crops. No further application possibilities are provided.
  • the substance mixtures according to EP-A-0 305 561 are liquid preparations for fire fighting, oil dispersants, cleaning agents for household and industrial use or a deodorant.
  • the main ingredient is a detergent mixture of a linear alkylbenzenesulfonate, a non-ionic detergent and a laurine superamide.
  • This agent may also contain vitamin B-6, sodium chloride, sodium bicarbonate and a minimal amount of water.
  • the invention was therefore based on the object of developing the sanitary cleaner described at the outset in such a way that on the one hand it develops the desirable germ-inhibiting function in the first phase of action, for example in a toilet bowl, and on the other hand does not interfere with the degradation of the microflora of the waste water in the second phase of action.
  • this object is achieved by a sanitary cleaner with a content of germ-inhibiting organic substances in an amount of 0.5 to 150 g / kg of sanitary cleaner and in germ-promoting organic substances resistant to lime-dissolving water-soluble acids in an amount of at least 10 mg / kg of sanitary cleaner and in one Foam carrier dissolved in the form of a water-soluble protein with a germ-promoting effect.
  • the invention further relates to the use of a mixture of substances as a sanitary cleaner, this mixture of substances comprising 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 resistant to lime-dissolving water-soluble acids contains germ-promoting organic substances in a concentration of at least 10 mg / kg, in particular from 10 to 1000 mg / kg.
  • 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 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 or alkaline earth metal salts, or also 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, such as 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, alan 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 germ-inhibiting ingredients of essential oils are: Thymol, Carvacrol, Therpineol, Cinol and Fenchon.
  • the essential oils are water-insoluble, but like the water-insoluble vitamins, they can be used with suitable, in particular environmentally friendly emulsifiers or solubilizers as germ-inhibiting substances in sanitary cleaners.
  • surfactants Practically all surface-active substances can serve as solubilizers for the group of substances described above.
  • the most suitable solubilizers for aqueous systems are selected according to the HLB system and must be determined experimentally for each individual essential oil.
  • Solubilizers with HLB values of 12 to 18 are particularly suitable for essential oils in aqueous systems.
  • Solubilizers which are described in Römpps Chemie-Lexikon, 8th ed., Vol. 3, p. 2399 are particularly suitable.
  • the following grouped surfactants are suitable: Anionic surfactants: fatty alcohol sulfonates, e.g. Na lauryl ether sulfate, soaps, e.g.
  • K stearate K stearate
  • Cationic surfactants Quaternary ammonium compounds, e.g. Didecyl-dimethyl-ammonium chloride, betaine derivatives, e.g. Fatty acid amidopropyl dimethylamino acetic acid betaine
  • 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.
  • Formic acid acetic acid, propionic acid, benzoic acid or simple derivatives of benzoic acid, sorbic acid, also in the form of suitable water-soluble salts thereof, such as the sodium and potassium salts, have proven to be particularly advantageous as germ-inhibiting organic acids.
  • the lime-dissolving organic acids such as citric acid
  • the germ-inhibiting organic acids generally stand out from one another in terms of the different effects in a suitable sanitary cleaner.
  • an organic acid can be lime-dissolving on the one hand and also have a germ-inhibiting effect.
  • it is preferred on the one hand to use such an acid which has a particular ability to dissolve limescale, and on the other hand to use such an acidic organic compound, which shows a particularly effective inhibition of germs.
  • the germ-inhibiting organic substances in the sanitary cleaner according to the invention regardless of whether it is in powdery, granular or liquid form, are present 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 most preferably in an amount of about 2 to 7 g / kg sanitary cleaner before.
  • 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 particularly suitable vitamins include: L-ascorbic acid, salts of ascorbic acid, in particular the Ca salt, L-ascorbyl palmitate, (+) - biotin, ⁇ -carotene, cholecalciferol, dehydroascorbic acid, ergocalciferol, folic acid, hydroxocobalamin, Niacinamide, nicotinic acid (niacin), D-panthenol, D-pantothenic acid, pyridoxal, pyridoxal-5-phosphate, pyridoxamine, pyridoxamine-5'-phosphate, pyridoxine, pydridoxine phosphate, riboflavin, riboflavin-5'-phosphate, rutin, rutin salt , in particular the rutin sulfate, thiamine, thiamine nitrate, thiamine phosphoric acid ester, thiamine pyrophosphate, al
  • 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 the amounts mentioned.
  • the germ-promoting organic substances are introduced into the product in such an amount 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 waste water.
  • 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 ingredients 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 and 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 strong dilution and thus accelerate or at least do not interfere with 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, 10 to 1000 mg of germ-promoting organic matter per kg of sanitary cleaner could be given, the range from about 100 to 800 mg / kg being preferred.
  • the substances mentioned, preferably amino acids, vitamins, orotic acid and p-aminobenzoic acid, are suitable as germ-promoting organic substances.
  • additives can be incorporated into the sanitary cleaner according to the invention, for example fragrances, dyes, biological foaming agents.
  • a water-soluble protein with a simultaneous germ-promoting effect such as water-soluble whey protein, is used as the foamer.
  • this water-soluble protein about 2 to 30 g, in particular about 5 to 10 g, of about 1 kg of powdered sanitary cleaner or also about 1000 ml of liquid sanitary cleaner are preferably used.
  • the invention does not preclude the addition of other substances known in the prior art, the selection of which is intended to retain the desired advantages of environmental friendliness, etc., as far as possible.
  • the essence of the invention shown above can be described particularly well with reference to the attached FIG. 1:
  • the ordinate indicates the number of germs per ml x 1000.
  • the abscissa describes the concentration of the sanitary cleaner in% in the wastewater.
  • the measurements were carried out twice, which is shown by the different symbols entered in FIG. 1. From the figure it can be deduced that the original bacterial count was 105 cells / ml in the toilet bowl and in the waste water.
  • the sanitary cleaner in powder form about 20 g in about 50 ml of water in the toilet bowl
  • the bacterial count goes to about zero.
  • 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 lime-dissolving water-soluble acid, the germ-inhibiting organic substances as well as the germ-promoting organic substances of natural origin. Due to the special composition and the consideration of further qualitative and quantitative aspects, particularly favorable effects in the first phase of action, e.g. achieved in the toilet bowl, and in the second phase of the effluent.
  • the sanitary cleaner according to the invention is harmless to humans and animals and the environment. It therefore fulfills the requirements and meets the wishes of many consumers with increasing environmental awareness.
  • This mixture eliminates 2 mg of biotin, 20 mg of nicotinamide, 10 mg of thiamine, 10 mg of p-aminobenzoic acid, 5 mg of pantothenic acid, 50 mg of pyridoxamine, 2 mg of cyanocobalamin (vitamin B 12) and 10 mg of orotic acid.
  • citric acid 175 g Sodium hydroxide 22 g Formic acid 10 ml Sodium benzoate 2 g Potassium sorbate 2 g Mixture of vitamins and amino acids (see below) 0.5 g Thickener (xanthan) 5 g soluble whey protein 10 g
  • the above mixture is made up to 1000 ml with water.
