Description

Sanitary cleaner

The invention relates to a sanitary cleaner in solid form containing conventional lime-dissolving, water-soluble substances, in particular conventional lime-dissolving, water-soluble acids, to germ-promoting organic substances resistant to the lime-dissolving, water-soluble substance in an amount of at least 10 mg / kg of sanitary cleaner and optionally other Additives.

The prior art described above is evident from international application WO 94/28100. In particular, it aims to maintain the desirable germ-inhibiting function in the first action phase of a sanitary cleaner, for example in a toilet bowl, and on the other hand to improve the degradation performance of the microflora of the waste water (in the second action phase). This enables hygienic cleaning of sanitary facilities without disrupting the microbial degradation of the organic substances in the wastewater. These apparently contradictory properties can be achieved by introducing the described germ-inhibiting or germ-killing active ingredients into the sanitary cleaner in such a concentration that their concentration above the minimum inhibitory concentration (MIC) when used in the first effective phase intended for this purpose, for example in the toilet bowl. lies. The "minimal inhibitory concentration" is a common technical term. At the same time, 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 particular advantage of this known procedure is that the breathability of the microflora in municipal wastewater can surprisingly be increased significantly. This leads to a noticeable reduction in the environmental impact, because the disinfectant effect is due to degradable natural substances, ie the lime-dissolving water-soluble substance, there in the form of a lime-dissolving water-soluble acid, the germ-inhibiting organic substances as well as the germ-promoting organic substances can be of natural origin. This is particularly beneficial for the environment, fulfills the requirements and meets the wishes of consumers with increasing environmental awareness. This known proposal can therefore be used in a wide range of applications, such as in the entire sanitary area, such as in particular in toilet bowls, urine pools, bathtubs, wash basins, shower trays and the like.

In the sanitary cleaner known from WO 94/28100, it has been shown to be desirable to have its limescale-releasing effect by means of a further gentle and non-toxic component, in particular in the first phase of action while maintaining the degradation capacity of the microflora of the waste water, and in the second phase of action. to improve. This is the object of the invention described below.

According to the invention, the above object is achieved by a sanitary cleaner, which is characterized in that the sanitary cleaner contains an open-chain or cyclic compound of the formula (I) R ^ N-CO-N-fy ^ as a germ-promoting organic substance, in which R "to R ₄ are each independently open-chain or cyclized and can have the following meanings: hydrogen, a lower alkyl group having 1 to 4 carbon atoms, a cycloalkyl group having 3 to 6 carbon atoms, an arly group in the form of a phenyl or naphthyl radical, an aralkyl group with 7 to 18 carbon atoms, an alkylaryl group with 7 to 18 carbon atoms or an O-, S- or N-containing heterocyclic group with 2 to 5 carbon atoms, the compound of the formula (I) also being wholly or partly in the form of a salt and the sanitary cleaner contains germ-inhibiting substances in one

Contains less than about 0.5 g / kg sanitary cleaner, especially less than about 0.4 g / kg sanitary cleaner.

It is surprising that, contrary to the trend-setting information of the prior art described above, the task is solved if the amount of germ-inhibiting organic substances per kg of sanitary cleaner, based on dry cleaning agents, substance, less than about 0.5 g / kg, in particular less than about 0.4 g / kg, and in particular the germ-inhibiting organic substance is completely excluded. This is the central idea of the invention described in detail below.

Although the two-phase effect as discussed above in connection with the relevant prior art is also discussed below, it should already be pointed out here that the invention does not use this two-stage effect alone, but can in principle also be used where the two-stage effect is not required. The following descriptions in connection with the two-stage effect are not intended to limit, but are only to be considered as examples.

The following urea derivatives should therefore fall under the above formula (I):

In the formula (I), the respective radicals R 1, R 2, R 5 and R 4 are preferably hydrogen, since the corresponding starting compounds are commercially available or easier to prepare. Particularly suitable in the context of the invention are the substituents which are specified in the above definition of the invention. The lower alkyl group with 1 to 4 carbon atoms are the methyl, ethyl, n-propyl, i-propyl and the various isomers of the butyl group. The cycloalkyl group with 3 to 6 carbon atoms in particular includes the cyclopropyl, cyclobutyl, cyclopentyl and cyclohexyl radical, the aralkyl group with 7 to 18 carbon atoms in particular the benzyl and phenethyl group, and the alkyl aryl group with 7 to 18 carbon atoms in particular Tolyl group and the heterocyclic group having 2 to 5 carbon atoms, in particular those in whose heterocyclic ring there is at least one oxygen, sulfur or nitrogen atom, suitable examples being the radicals of oxirane, tetrahydrofuran, dioxane and pyran can. In principle, the compounds of the formula (I) are used in whole or in part in the form of their salts or other precursors, which can promote solubility. In individual cases, this can only lead to the desired solubility in the sanitary cleaner according to the invention. Compounds which release the compounds of the formula (I) or theirs only in the aqueous medium can therefore be considered

Let effectiveness unfold there. The following quantities always relate to the compounds of formula (I) as such or their proportion within the suitable derivatives or compounds.

Suitable salts of the ureas or urea derivatives mentioned can also be used within the scope of the invention, provided that they do not impair the desired mechanism of action. For example, chlorides, sulfates, in particular hydrogen sulfate, phosphates, in particular the hydrogen phosphates are suitable. Urea phosphate is particularly effective.

Accordingly, the incorporation of urea phosphate (urea phosphate) in the sanitary cleaner according to the invention is of particular advantage. Urea phosphate crystallized in pure form is colorless, has a melting point of 118 to 119 ° C, is soluble in water, alcohol, acetic acid, glycerin, ethylene glycol and the like. The aqueous solution is acidic. In addition to synthetic fertilizers (as an N / P source), another advantageous practical use has been found to be due to its acid action in solder, melt flux, pickling, metal and rust remover and as a catalyst for acid-catalyzed synthetic resins (see p. 1723, Römpp Chemie-Lexikon, Thieme Verlag, Vol. 3, 9th ed. 1990).

There is no suggestion in the literature to use this in sanitary cleaners. In the context of the present invention, it has been shown that urea phosphate has an exceptionally good descaling capacity. On the other hand, due to the urea released in solution, it promotes desirable effects in the second phase of action. Its hazard potential is just as harmless as that of citric acid. Urea phosphate thus not only satisfies the requirement of the state of the art to be assessed positively according to WO 94/28100 for the addition of urea, but also at the same time also fulfills the requirement of a safe and effective limescale-dissolving effect which, for example, is significantly stronger than citric acid. Therefore, the lime-dissolving, water-soluble substance, for example in the form of an acid, such as in particular citric acid, can be wholly or partly by the mono-substance

Urea phosphate to be replaced. Therefore, urea phosphate is advantageous both for the increased cleaning effect in the first and for increasing the microbial breakdown of organic substances in the second phase of action. In addition, it has been shown that, unlike, for example, a lime-dissolving organic acid such as citric acid, urea phosphate does not have a corrosive effect on metal surfaces, but rather has a protective effect. In addition, the urea released in solution from urea phosphate promotes cleaning due to its special solution properties. Among the salts of urea (or isourea) with acids in the form of crystalline uronium salts, urea phosphate in particular is distinguished by its special properties as a stable, non-hygroscopic, readily water-soluble acid salt (uronium dihydrogen phosphate). As already mentioned, salts of urea or of the mentioned derivatives with other physiological and non-physiological acids are therefore also suitable within the scope of the invention, such as e.g. Uronium chloride, hydrogen sulfate, sulfate and the like.

In addition to the compounds of formula (I) mentioned, germ-promoting organic substances can be used, which are known from the international application PCT / EP 90/01718. The known germ-promoting and germ-inhibiting organic substances have certain things in common. Thus, like the rest of them in particular urea and the urea derivatives suitable for the purposes of the invention, they are sufficiently resistant to organic acids or their salts in the usual temperature and pH range.

As already mentioned, the present invention can completely dispense with germ-inhibiting organic substances. However, it is still in line with the idea of the invention, in particular the maximum amount to less than 0.5 g / kg of sanitary cleaner to be less than about 0.4 g / kg and particularly to less than 0.2 g / kg and / or to exclude these substances. The following descriptions of the germ-inhibiting organic substances must therefore comply with these quantitative framework conditions of the invention:

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. In addition, the acidic organic substances should be used to develop the desirable germ inhibition should be sufficiently water-soluble. In individual cases, the carboxylic acid itself can be sparingly water-soluble, but the suitable salt thereof can 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 and malonic acid, and also various fatty acids with 6 to 12 carbon atoms, e.g. Sorbic acid or 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 since they are not themselves water-soluble and, moreover, the majority of their salts also do not meet the requirement of 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, tartaric acid and citric acid, and oxo acids, such as acetoacetic acid and pyruvic acid. Sufficiently water-soluble aromatic carboxylic acids are particularly suitable, such as in particular benzoic acid, salicylic acid and also other phenol carboxylic acids.

Essential oils are also of particular advantage. Essential microbicidally active essential oils are in particular: thyme oil, citrus peel oil, eucalyptus oils, clove oil, origanum oil, rosemary oil, cinnamon oil, alum oil, camphor oil, coniferous oils and Fenchenöle. The thyme oil is particularly preferred. The active ingredients contained therein can also be used in their place. Examples of germ-inhibiting ingredients of essential oils are: Thymol, Carvacrol, Terpineol, Cineol and Fenchon. The essential oils are water-insoluble, but just 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.

Formic acid, acetic acid, propionic acid, benzoic acid or simple derivatives of the have also been found to be particularly advantageous as germ-inhibiting organic acids

Benzoic acid, sorbic acid, also in the form of suitable water-soluble salts thereof, as demonstrated by the sodium and potassium salts.

Practically all surface-active substances ("surfactants") can serve as solubilizers for the group of substances described above. Choosing the most suitable

Solubilizers for aqueous systems are based on 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. In particular, such solution mediators come into question, which are described in Römpp Chemie-Lexikon, 8th ed., Vol. 3, p. 2399. Basically, the following grouped surfactants are suitable: Anionic surfactants: fatty alcohol sulfonates, e.g. Na lauryl ether sulfate; cationic surfactants: quaternary ammonium compounds, e.g. Didecyldimethylammonium chloride, betaine derivatives, e.g. Fatty acid amidopropyldimethylaminoacetic acid betaine; non-ionic emulsifiers or solubilizers: fruit acid esters of mono- and diglycerides, e.g. Citric acid esters, polyoxyethylene glycerol fatty acid esters, e.g. Polyoxyethylene glycerol monolaurate with 30 mol EO.

It can be seen that the lime-dissolving organic acids, such as citric acid, and the germ-inhibiting organic acids generally stand out from one another in terms of the different effects in a suitable sanitary facility. In

In individual cases, an organic acid can be lime-dissolving on the one hand and beyond also have a germ-inhibiting effect. In general, 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 are present in the sanitary cleaner according to the invention, regardless of whether it is in powdery, granular or liquid form, in the quantitative range described above.

In the context of the invention, in addition to the compounds of the formula (I) or the salts thereof, additional and preferably amino acids and / or orotic acid or suitable salts or derivatives thereof and vitamins can be used as germ-promoting organic substances. The derivatization mentioned must not go so far that the desired effect of germ promotion is impaired. Particularly suitable amino acids are: alanine, arginine, asparagine, aspartic acid, citrulline, cysteine, cystine, glutamine, glutamic acid, glycine, histidine, hydroxyproline, isoleucine, leucine, methionine, ornithine, phenylalanine, proline, serine, threonine, tryptophan, typhine as well as valine. The particularly suitable vitamins, including their provitamins, include: L-ascorbic acid, salts of ascorbic acid, in particular the Ca salt, L-ascorbyl palmitate, (+) - biotin, beta-carotene, cholecalciferol, cyanocobalamin, dihydrofolic acid, dehydroascorbic acid, Ergocalciferol, folic acid, hydroxocobalamin, niacinamide, nicotinic acid (niacin), D-panthenol, D-pantothenic acid, pyridoxal, pyridoxal-5'-phosphate, pyridoxamine, pyridoxamine-5-phosphate, pyridoxine, pyridoxine phosphate, riboflavin, riboflavin-5' , Rutin, rutin salt, especially the rutin sulfate, tetrahydrofolic acid, thiamine, thiamine nitrate, thiamine phosphoric acid ester, thiamine pyrophosphate, alpha-tocopherol, delta-tocopherol, alpha-tocopheryl acetate, alpha-tocopherylquinone, alpha-tocopheryl tocopheryl phosphate , Vitamin A acetate, vitamin A aldehyde, vitamin A alcohol, vitamin A acid, vitamin B4 (Ademin), vitamin Ki, vitamin K., vitamin P and vitamin U (methionine S-methylsulfonium chloride ). In the event that the vitamins have acidic or basic groups, suitable salts thereof can generally also be used. When using the sanitary cleaner according to the invention, which can be present, for example, in powdered, granulated form or in aqueous form or aqueous dispersion, it is diluted with a little water, for example in the toilet key. There, the active hygiene ingredients have a germ-inhibiting or germicidal effect, so that the germ-promoting substances initially remain ineffective. After flushing the toilet bowl after exposure to the sanitary cleaner, the concentration of the germ-inhibiting organic substances is reduced below the MIC value and therefore 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 that degrade the organic substance even after rinsing or after a 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 form of the compounds of the formula (I) in the sanitary cleaner according to the invention is not critical. In individual cases it must be tested which minimum concentration is used in each case. An amount of about 10 mg / kg of sanitary cleaner is regarded as the minimum quantitative framework, preferably 150 g / kg of sanitary cleaner as the maximum framework, and the framework is preferably about 10 mg / kg to about 80 g / kg of sanitary cleaner, in particular about 0.05 g to 60 g / kg sanitary cleaner. Accordingly, the quantities in connection with the germ-promoting organic substance of formula (I) refer to this as such and not to its salt.

A minimum quantity of 10 mg / kg and in particular of about 10 to 1000 mg / kg could be mentioned as a quantitative guideline for the further germ-promoting organic substances, which can be used in addition to the designated germ-promoting organic substances in the form of the compound of formula (I) . The substances mentioned, preferably amino acids, vitamins, orotic acid and p-aminobenzoic acid, are suitable as germ-promoting further organic substances. A mixture of about 2 mg of biotin, about 20 mg of nicotinamide, about 10 mg of thiamine, about 2 mg of cyanocobalamin (vitamin B12), 300 mg of urea phosphate and about 10 mg of orotic acid is of practical importance, this mixture preferably being about 1 kg Sanitary cleaner is present. To optimize the desired effects of the germ-promoting organic substances, these are selected qualitatively and quantitatively with regard to the respective milieu when they are used in a mixture.

In the context of the invention it is particularly advantageous if, in the case of a solid sanitary cleaner, this anhydrous magnesium sulfate as filler and neutral salt (without influencing the pH value), in particular in an amount of preferably about 10% by weight to 85% by weight. %, in particular approximately 30% by weight to 60% by weight, is added. This additive leads to a significant increase in temperature due to the strong positive heat tone when the sanitary cleaner is dissolved in water with the advantages mentioned below. Of course, it is obvious to the person skilled in the art that the anhydrous magnesium sulfate can also be replaced by other anhydrous neutral salts which correspond to its property profile and that such salts thus develop a novel principle of action in solid sanitary cleaners which has not hitherto been found in the prior art. Due to the strong positive heat effects mentioned when dissolving the sanitary cleaner according to the invention in water due to incorporation of the neutral salts referred to, in particular the anhydrous magnesium sulfate, the following advantages arise: 1. generally better removal and dissolution of dirt residues, 2. the emulsifying effect of added surfactants as well as urea (or its salts) is accelerated and thus fat / oil films are dissolved more quickly, 3. the germ-promoting effect in the context of the second active phase is favored as a result of the temperature optimization and 4. the release (volatility) of added fragrances (for example also in sanitary cleaning stones) , gels, etc.) is effectively promoted as a result of the temperature increase. In contrast to sodium hydroxide, which also has positive heat of solution, but is strongly alkaline and caustic, in numerous known sanitary drain cleaners, anhydrous magnesium sulfate in particular is a completely safe, consumer and environmentally friendly neutral salt.

Further known additives can be incorporated into the sanitary cleaner according to the invention, for example fragrances, dyes, biological foaming agents. A water-soluble protein substance with simultaneous germ-promoting proven effective, especially water-soluble whey protein. When a water-soluble protein substance is used, about 2 to 30 g, in particular about 5 to 10 g, are preferably used for about 1 kg of powdered sanitary cleaner or also about 1000 ml of liquid sanitary cleaner. Of course, the invention does not preclude the addition of other substances known in the prior art, the selection of which is intended to preserve the desired advantages of environmental friendliness, etc., as far as possible.

Effective cleaning, i.e. removing and removing deposits and accumulations of inorganic and organic dirt from surfaces, often places the same requirements on the main active ingredients of suitable products when it comes to sanitary facilities, kitchen and food businesses and the respective drains goes. In this context, the sanitary area includes sinks, shower basins, bathtubs, bidets, urinals, toilets, floor and wall tiles and other surfaces. In kitchens, canteens, restaurants, snack stands, food factories (production, processing and processing facilities as well as storage, transport and sales facilities), this also deals with specific objects, wall and floor coverings. Stationary or mobile facilities should not be differentiated in this regard. The requirements mentioned above relate to inorganic parts, in particular lime from drinking water, waste water or process water, and organic parts of biological or abiological origin. Representative of the organic parts in the sanitary area are mainly soap residues, surfactants, body fat and desquamation, creams, care oils, hair, urine and feces, while in the other areas specified above, depending on the facility, more about fats, oils, lard, butter , Vegetable schnitzel, coffee and tea leftovers as well as various small bread and food leftovers. In all areas, the respective parts often accumulate in the water-bearing pools and pipes, such as those in siphons or at other bends and constrictions. If the accumulations become deposits and do not reach subsequent wastewater, routine flushing, mechanical or chemical removal, complete blockages result. The sanitary according to the invention some can be used with particular advantage for all the above purposes. These applications are therefore within the scope of the present invention.

In the following, the invention will be explained in more detail using four recipe examples:
