DD242421A1 - METHOD FOR PRODUCING A CLEANING AGENT FOR SANITARY CERAMICS - Google Patents

Abstract

The aim of the invention is a cleaning agent for green and gentle cleaning and care sanitaerkeramischer products with high cleaning effect, which prevents with regular use water and Urinsteinbildung and deposition, is toxicologically and dermatologically safe and has a disinfecting effect. The object is achieved by preparing an active ingredient concentrate according to the invention from a plurality of components in a homogeneous mixture, which is filled into aerosol containers in a known manner and treated with a propellant in the ratio of 6.5 to 20% to 93.5 to 80%.

Description

the active ingredient concentrate is filled in a known manner in aerosol containers and applied with a propellant consisting of isobutane or propane or a mixture of both in the ratio of 6.5 to 20% to 93.5 to 80%.

Field of application of the invention

The present invention relates to a means for cleaning and care of sanitary ware products and sanitary facilities.

Characteristic of the known technical solutions

For the cleaning of sanitary ware products a variety of technical recipe solutions is known. A known cleaning agent contains water-soluble salts of acidic sulfuric acid esters and up to 15% by weight of boric acid. The acidic character of the cleaning agent does not permit aerosol application without corrosion problems in corresponding packaging means. The availability of the selected components is limited.

Another cleaning agent is described in DE-OS 2511854. The cleaning agent contains 5-30 parts of urea-formaldehyde polymer particles, 70-95 parts of halide-containing solvent, up to 3 parts of silica and antistatic agents, with the cleaning agent concentrate being exposed to a fluoromethane-based aerosol propellant. On the basis of the formaldehyde content, a toxicological harmlessness of the cleaning agent is not given. The content of polymer particles of the order of 10 to 105pm does not allow a trouble-free application as a spray product with regard to the possible clogging of the spray heads and the valves.

In DE-OS 2913043 a liquid detergent is shown which contains the following components: up to 10 wt .-% of nonionic surfactant

up to 2% by weight of water-soluble polymer based on polyethylene glycol and cellulose ether up to 10% by weight of builder substance

and up to 15% by weight of water-soluble or emulsifiable organic solvents. The high proportion of surface-active and other active ingredients in this cleaning agent is uneconomical. A detergent prepared on the basis of quaternary ammonium compounds and phosphorocarboxylic acids is shown in DE-AS 2141982.

The technical production of the components is technologically complex.

In DE-OS 2932942 a cleaning agent is described, which contains components that can be produced only with great technical effort.

The components include alkali, ammonium or amine salts of alkylarylsulfonic acid or alkylsulfuric acid, sodium gluconate and sodium metasilicate.

An economically unacceptable proportion of surfactants up to 50% by weight and additional proportions of up to 30% by weight of citric, succinic and glutaric acid are specified in a cleaning agent according to DE-OS 3237608.

In DE-OS 2750528 a method for keeping clean toilet bowl is described. The cleaning concentrate contains hypohalite as a bleaching agent, alkali metal salts of sulfonic acids and water. As an aerosol application, it leads to corrosion problems on tinned containers.

Further detergent compositions for sanitary facilities are presented in DE-OSs 2162790, 1959652 and 160833. These formulations also have disadvantages in terms of technological production conditions and economic effectiveness.

The most essential ingredients of the detergent formulations shown in the aforementioned DE-OS are

- Ethoxyalkylphenol

- Polyethoxyethylenester

- alkyl benzene sulphonate

- quaternary ammonium compounds

- alkylphenols

- Phosphoric acid

- Sodium sulfite

- Sodium silicate

Other disadvantages occur in the known technical solutions due to lack of disinfecting effect and poor foam stability. In many known solutions, the liquid film runs off quickly and thereby reduces the contact time of the active ingredient.

Object of the invention

The aim of the invention is a cleaning agent in aerosol application for thorough but gentle cleaning and care of sanitary ware products with high cleaning effect, which with regular use prevents water and Urinsteinbildung and deposition, is toxicologically and dermatologically harmless and has a disinfecting effect.

Explanation of the essence of the invention

The invention has for its object to produce using inexpensive and readily available components a spray product for the cleaning of sanitary ware, which is hygienically perfect and equipped with optimal foam stability.

The technical object of the invention is achieved by the following components are combined in a homogeneous mixture to form a concentrate.

- isopropanol 12-16Ma .-%

- Nonionic surfactant based

of an ethoxylated alkylphenol 10-14% by weight

- anionic surfactant on the basis

of mono- and diesters of phosphoric acid 3-5% by mass

- Mixture of higher, saturated fatty alcohols of chain length C ₁₆ -C ₁₈ 0.3-0.5 Ma .-%

- Sodium or ammonium salts

Nitriloacetic acid 0.8-1.2 mass%

- Tetrasodium ethylenediaminetetraacetate 2-3Ma .-%

- Quaternary ammonium chloride or others

Water- or alcohol-soluble disinfectants 1-3Ma .-%

- Perfume oil 0.1-0.3% by mass

- optionally fluorescein sodium 0,001-0,002 Ma .-%

- demineralized water balance to 100% by mass

The cleaning concentrate is treated with a propellant consisting of isobutane or propane or a mixture of both, in a ratio of 6.5% to 20% to 93.5% to 80%.

The cleaning agent according to the invention allows a hygienic cleaning of sanitary ware under reduced working time. The foam stability is optimal. After breaking the foam, a liquid film is formed, which slowly runs down on the surfaces to be cleaned. As a result, an additional dirt pickup and an increased cleaning effect is achieved.

embodiment

The invention will be explained in more detail by way of example.

example 1

A cleaning concentrate consisting of 15% by weight of isopropanol; 12% by weight of nonionic surfactant; 4% by mass of anionic surfactant; 0.4 mass% saturated fatty alcohols C ₁₆ -C ₁₈ ; !, Granny ^ / oTrinatriumnitriloacetat. 2.5 mass% tetrasodium ethylenediaminetetraacetate; 2Ma .-% aqueous solution of benzalkonium chloride (15%), 0.1% by weight of synthetic-based perfume oil; 0.001% by mass of fluorescein sodium and the remainder to 100% by mass of demineralized water are added with isobutane as blowing agent. The filling volume of the aerosol container contains 235 ml of active ingredient concentrate and 35 ml of propellant gas. It was found a self-cleaning effect of 56% and a total cleaning effect of 100%, a very good gloss effect with good disinfecting effect after treatment of sanitary ware. The wall adhesion according to standardized measuring method is 4.5 min.

The concentrate was after filling with 15% (to 85% concentrate) blowing agent, consisting of an isobutane / pentane mixture applied.

After application to a test-soiled ceramic plate, an excellent disinfecting effect, a cleaning efficiency of 86% as a reflectance and a total of 12% could be determined.

The foam stability was 45 minutes.
