Means for cleaning and disinfecting toilet cisterns and basins

Field of application of the invention

The invention relates to means for cleaning and disinfection of toilet cisterns and basins, which prevent the formation of Kalkablagerangen, solve the resulting deposits and are suspended in blocks that are contained in suitable containers in the cisterns.

Characteristic of the known technical solutions

It is known that toilet hygiene cleaners generally consist of blends containing surfactants, disinfectants, bleaches, chelants, acids, binders, fillers, dyes and fragrances. These_means are usually hung in a suitable container in the cistern (DE-OS 29 0? 029). They are used as blocks, as tablets (DE-OS 29 10 955) or as a powder, with the formation e'ines block in the cistern (EP 014 979), applied, '

, 2477

It is known that these agents anionic and / or nonionic surfactants, such as fatty alcohol sulfates, alkylbenzenesulfonates (DE-OS 2,907,029), alkali metal succinates, alkali _y tauride (DE-OS 2 910 955)> ethylene oxide-propylene oxide Bl'ockpolymerisate, Fatty acid mono- and di-alkanolamides and their ethoxylates (DE-OS 2,910,955) included.

As disinfecting and bleaching agents chlorine- or oxygen-releasing agents such as chlorocyanurate, calcium hypochlorite or sodium perborate are used. If these agents dissolve limescale deposits or prevent their formation, appropriate active ingredients, such as ethylenediamine-potassium acetate, citric acid, malonic acid, tartaric acid and the like, are added to them (DE-OS 2 907 029).

Furthermore, these agents usually contain binders based on substituted cellulose, such as cellulose ethers, methyl cellulose, etc., and / or completely synthetic polymers, such as polyvinyl alcohol, polyvinyl acetate, polyacrylonitrile, and the like. (DE-OS 2 910 955) or water-binding salts (EP 0 014 979).

Acid dyestuffs (German Offenlegungsschrift No. 2,910,955), triphenyl methine dyestuffs (German Offenlegungsschrift No. 2,162,790) or triarylmethane dyestuffs (EP 0 014 979) and urea, sodium carbonate, sodium sulfate, borax as fillers and commercial fragrances for the above agents are used as dyestuffs , All known detergents for toilet cisterns and basins contain non-biodegradable dietary fiber or heavy biodegradable substances .. At the same time in most known means, a phase separation, so that either the dye is dissolved out first and so the rinse water is colorless prematurely, although still detergent is present, or the detergent is dissolved out faster than the dye, so that a cleaning is faked, although the agent is already used up.

Usually, these agents are sufficient for an amount of 40 to 10Og for 300 to 600 rinses (DE-OS 2,907,029).

Object of the invention

The aim of the invention sind.Mittel for cleaning and disinfection of toilet cisterns and basins, which contain no fiber, in particular salts, and have a long life and high activity.

Explanation of the essence of the invention

The object of the invention is the development of a new formulation for cleaners of toilet cisterns and basins, which eliminate the deficiencies shown and meet the objective

 It has been found that an agent of the following composition

From 5 to 40% by weight of C ₁₆ -C 15 fatty alcohol polyglycol ethers with 65 to 100 mol of ethylene oxide, 60 to 93% by wt of C ₈ to C ₁₂ -alkylphenol polyglycol ethers with 45 to 65 mol of ethylene oxide, 0.5 to 2% by wt. N-methyl-N-benzylaniline, from 0.4 to 8% by weight of water, from 0.8 to 7% by weight of a basic blue-colored dyestuff, preferably Color Index Basic Blue 41, from 0.01 to 2% by weight of glycol , 2 to 8% by weight of perfume oil and 0.001 to 5% by weight of acetic acid _; · '-

complies with the objective and has excellent cleaning and disinfecting properties. Surprisingly, it has been found that the use of Cq to 'C ₁₂ -alkylphenol polyglycol ethers with 40 to 65 moles of ethylene oxide in conjunction with C ₁₆ to CgQ fatty alcohol polyglycol ethers with 65 to 100 moles of ethylene oxide gives dimensionally stable blocks which are melted by known processes »

2477

These dimensionally stable blocks thus obtained suspended in suitable containers in the cistern, have an excellent life of 800 to 1000 rinses, which is significantly above the current high level for the same substance use «. -

In addition to the very good cleaning effect of the above agents, a gloss effect in the toilet bowl is achieved as an additional effect, which remains even after evaporation of the water content. This effect is due to film formation on the treated and cleaned surfaces and is due to the highly oxyethylated nonionic surfactants.

The addition of acetic acid prevents the deposition of caustic and urine scale in the cisterns and basins and the associated piping systems and dissolves any scale deposits that have already formed. By adding a blue basic azo dye, a good coloration of the product could be achieved. Especially when using Color Index Basic Blue 41, preferably as a liquid formulation, a uniform distribution of the dye on average as well as a uniform resolution of all individual components in the water was achieved. Not only does the dye give the water a pleasant color, it also indicates to the user when the active ingredient is consumed, d. h., The '/ rinse water is colorless.

When N-methyl-N-benzylaniline was added to the above compositions, very good disinfecting properties were obtained, which was not to be expected, and a synergistic effect between the basic azo dye type Color Index Basic Blue 41 and the N-methyl-N- benzylaniline "The investigations of the disinfecting effect on KoIibakterien and Proteusbakterien have shown that after 15 min. Exposure time, a significant reduction in the number of bacteria

ο -. "

could be detected in less than 10 germs / 3 .cm * "in the Agarabklatsch method, which corresponds to a very good disinfecting effect ¹ .

2477

For N-methyl-N-benzylaniline in conjunction with the above agents without Color Index, Basic Blue 4-1, the count was 15 min. greater than 70 nuclei / 3 cm, the Color Index Basic Blue basic azo dye in combination with the above agents without N-methyl-N-benzylaniline was greater than 150 nuclei / 3 cm

Glycol is a good superplasticizer for the melting of the individual components and their subsequent casting into fittings.

Surprisingly, it has been found that the addition of glycol r accelerates the swelling process of the fittings in the cistern water and liberates the active ingredient more rapidly. This is due to a high initial effect of the glycol. ; By storing the shaped pieces in a corresponding container, a metered release of the active ingredient is carried out for each individual flush ο / ^v '.
