Description

FIELD OF THE INVENTION The present invention relates to a water softening, washing and cleaning powder enhancing composition for machine washing and / or cleaning similar machines and their surfaces to prevent limescale formation.

The closest, but not identical, compositions of the present invention, known in the art and published in the literature, which, although containing similar active ingredients, are used in different proportions, amounts, and combinations.

From a large body of literature reviewed, it has been found that there are many water softening methods and water softeners:

For example, Juhász, Éva-Lelkesné, Erős Mária: Surfactants Pocket Book, Technical Publication 1979 (pages 254-255) describes an industrial cleaning agent for the cleaning of metal surfaces to remove oily, greasy impurities containing sodium carbonate, sodium hydroxide, trisodium phosphate and 2-3 Contains% surfactant.

German Patent DE 2 752 984 protects a process for the preparation of a pre-wash detergent, characterized in that the slurry comprises: 20-50% water,

It is a mixture of 5-50% inorganic salt and contains 0.5-5% of benzenesulfonic acid salt. The final product, the particulate prewash detergent, contains the following ingredients: Sodium sulfate, borax, sodium toluene sulfonate, tripolyphosphate, sodium carbonate, sodium silicate, oxo-alcohol.

DE 2 847 437 has two main active ingredients: potassium tripolyphosphate and potassium hydroxide. It also contains sodium tripolyphosphate, sodium silicate and sodium ethylenediaminetetraacetate.

German Patent No. 3 532 031 protects a patent relating to a process for reducing carbonate in waters, particularly drinking water. The purpose of the process is to reduce the amount of precipitants. It mentions potassium hydroxide, soda ash and sodium hydroxide as precipitants.

U.S. Patent 4,595,520 discloses the manufacture of a solid alkaline detergent comprising the following active ingredients:

Soft water, sodium hydroxide, sodium carbonate, sodium tripolyphosphate, sodium hypochlorite, sodium metasilicate, sodium sulfate, sodium alkyl sec sulfonate.

U.S. Patent No. 4,680,134 protects a process for the manufacture of a solid detergent which is combined with a softening agent. The plasticizer component is a quaternary ammonium compound. The detergent composition is the same as that described in the previous patent.

Hungarian Patent Publication No. HU 200 364 B protects alkaline liquid cleaners. The main active ingredients are:

Sodium hydroxide, potassium hydroxide, dimethyl laurylamine oxide, alkyl dimethylamine oxide, sodium lauryl sarcosinate, potassium permanganate, potassium bichromate, sodium hypochlorite.

The products of the present invention are commercially available powdered mixtures of a similar purpose, e.g. the German Calgon and also the German Antique.

Calgon water softener approx. It contained 50% polyphosphate, 40% sodium silicate, dodecylbenzene sulfonate and EDTA.

In recent years, it has been found that EDTA is not biodegradable. May be harmful in drinking water. Its use has been banned in some countries. They limit the amount of phosphates. Therefore, the components of the product have been changed and the current composition of Calgon is Zeolite, Na Sulfate and Surfactant.

The anti-alkali water softener consists of Sodium Aluminum Silicate, Polyacrylate and Alkyl Polyglycol.

Each of the solutions described above differs from our invention in that they have a different purpose and purpose other than Calgon and Antikalk. But it differs from all the patents listed in that it does not contain, for example, the following active ingredients:

- alkali metal hydroxides (NaOH, KOH)

- filler, e.g. sodium sulfate, a technology that is significant in terms of thermal spraying

- sodium hypochlorite

- simple phosphate (ortho-phosphate)

alkyl polyglycol ether

- oxo-alcohol.

The use of these components, although highly effective, is not considered to be a good solution because of their drastic effects, as they can be detrimental to textiles, cause corrosion on metal surfaces, but are not indifferent to the environment or wildlife.

In view of the foregoing, it is an object of the present invention to provide a mixture of substances which exhibit excellent water softening activity, both salts having a constant and variable hardness of water. It also has a good cleaning effect. When added to built-in detergents, it increases the detergent effect and makes washing economical by investing in valuable detergent cleaning because water is softened by the additive. It has no damaging effect on textiles and has an inhibitory effect on metal surfaces. By preventing the formation of scale, it increases the operational safety and lifetime of the machines.

The above objective is to use a mixture of substances-

let's make that % 10-401 Sodium tripolyphosphate 25-501% Sodium carbonate 5-201% Sodium silicate 5-8% alkylphenol polyethylene glycol ether as well as 10-301% zeolite 2-5% a copolymer of methyl vinyl ether maleic anhydride 1-21% polyvinylpyrrolidone 1-10% hydroxyethyl ethylenediamine tetraacetic acid 4-5% citric acid 2-61% Sodium chloride contain.

Effect of the components used in the invention

HU 210 120 Well-known from literature and practice with many years of experience.

Carbonates greatly help to soften the water and ensure alkalinity of the water. Ecologically, carbonates are harmless. Na-silicate is a water softener, ensures alkalinity of the solution and prevents corrosion, is not harmful to the environment.

ANa-tripolyphosphate is an excellent peptide-washing additive. It is effective against salts causing variable water hardness. Recently, the amount of use has been limited, so in the present invention, part of the invention has been replaced by Zeolite, which has a water softening effect, does not pollute the water, the environment and uses new types of advanced additives (Gantrex-AN-119, Citric acid, PVP K-15 and TRILON-C ).

Na chloride is a stain remover, its environment is not harmful.

The wetting surfactant is Lutenzol AP10, which is a nonionic surfactant and is a weak surfactant in its own right, but together with the other components used, it has been found to be an effective wetting agent.

Good results were also obtained with ARKOPAL-N-100 which is also a nonionic surfactant (Nonylphenol Polyglycol Ether) and showed excellent wetting properties in the medium used despite the low concentration.

According to the manufacturer's certification, both surfactants are 80% biodegradable.

Various tests were performed to determine the degree of water softening using 30 nk ° hard water.

- The water softener effect alone and added to a built-in detergent powder was determined.

- The water softening effect was measured as a function of concentration.

- The Ca-binding capacity of the product has been determined and compared with commercially available foreign products of the same purpose.

HU 210 120 A

- It makes the use of detergents economical.

- The water softener has a better Ca-binding capacity than similar products.

In summary, the water softening effect of the water softener washing and cleaning powder powder according to the invention is significant and well measurable. When added to the recommended minimum concentration of 4 g / l or to a solution of detergent at a concentration of 5 g / l, the water softening effect can be nearly doubled. Depending on the construction of the detergent, the degree of softening effect varies. 30 nk' hard water used for the test can be softened to 34-38% by a 5 g / l detergent solution. The 5 g / l solution of the water softener according to the invention alone (without detergent) reduces the hardness of 30 nk 'water to 13.2 nk °, ie softens the water by 44% or binds the inorganic water hardening agent. salts.

When added to detergents at a concentration of 4 g / l, soften 30 nk' hard water by 65.2-76%. The combined effect is significantly better than the best detergent alone.

The water softener-cleaning effect of the product varies as a function of concentration, and at higher concentrations the water softening effect increases. At a concentration of 7-10 g / l, the water softener is 100% water hardness 0.

- The great benefit of using the product with the detergent is that it softens the water, so that the active ingredients of the detergent are completely spent on cleaning.

The effectiveness of the washing is increased, since the detergent does not need to be overdosed, valuable substances such as: Naperborate, enzyme, optical bleach, surfactants do not enter the drain.

- Prevents limescale formation and sedimentation when used regularly. With this, for example. the safety and lifetime of the washing machine can be increased and heat transfer improved.

- Removes grease, dust, and solid particles from metal surfaces when used for periodic cleaning in the washing machine manual.
