Description

BACKGROUND OF THE INVENTION The present invention relates to a sealable composition for cleaning smooth, glossy surfaces based on fatty alcohol sulfates and sulfosuccinates.

Existing cleaning agents used for the same purpose are based either on a combination of organic solvents, predominantly alcohol type, such as ethyl alcohol, isopropyl alcohol and the like, or when using heavily soiled glass surfaces, a combination of detergent cleaners to remove coarse soiling.

Mixtures of alkyl sulphates, alkylarylsulphonates and alkyl polyglycol ether sulphates are usually suitable detergent cleaners.

The detergent compositions hitherto used must always be removed with water or with further cleaning agents, since they leave residues which cause dull stains on glossy surfaces. The disadvantages of solvent types are mainly that they are flammable and there is always a risk of ignition when working with them. Difficult handling of these cleaning agents is mainly in the cleaning of windows and glass panes in new buildings, where simultaneous and other finishing work such as liner welding, etc. is performed, which excludes the use of said cleaning agents. They are also disadvantageous when cleaning window frames, where they can disturb the glossy surface of used enamels. However, working with solvent cleaners requires considerable caution even in homes where open fire is used.

The disadvantage of the present invention is to eliminate or substantially reduce the composition of the invention according to the invention which comprises a mixture of alkyl sulfates of the formula

R-O-SO2-Me, where

R is alkyl C 8 to C 8, g a

Me, is Na, K, Li, | Mg, Al and sulfosuccinates of the general formula

H-C-COO-R.

AND

HC-COO-R ₂ where

R 1 is an alkylolamide R-CO-NH-C 1-4 -CHg- in which H is C 8 -C 8 alkyl, gan is 2 to 5 and / or C ₈ -C ₆ alkyl,

R 8 is an alkali metal, aaonium, and / or when R 8 is an alkyl C 8 to C, g then R ₂ is an alkali metal, ammonium or an alkyl C 8 to ΰ, θ,

X 1 and X ₂ are hydrogen or SO ₂ Me ₂ , wherein when X is SO 2 Me ₂ , X ₂ is hydrogen, and when X is hydrogen, X ₂ is SO 2 Me, and Me ₂ is an alkali metal or ammonium, in a weight ratio of 1: 0.3 to 10.

The composition according to the invention is constituted by an aqueous solution of a mixture of said composition at a concentration of 1.5 to 20% by weight. active substances. In a concentration of 1.5 to 10 wt. The active substances may contain 4 to 10 wt. a propellant gas or propellant gas mixture and and to be filled into a vial for aerosol use.

The novel detergent composition according to the invention has good cleaning properties characteristic of surfactants and, moreover, the combination of both surfactants is chosen such that, with good wetting and cleaning properties, impurities can be easily mechanically removed and the surface flushed without leaving visible stains. Said cleaning agent has universal applications for glass surfaces, but also glossy coatings, so that windows and window frames can be cleaned in the same way. The use of sulfosuccinates in combination with fatty alcohol sulfates also provides temporary protection against sweating of the glass when the temperature changes, which can be advantageously used when cleaning car windows. The product is practically non-toxic and non-flammable, which, with good wetting properties, is of great importance for the versatility of use in domestic cleaning work, cleaning standard-equipped flats in prefabricated houses before handing it over and cleaning car windows. . Considerable importance lies in the safe application in terms of flammability. The application itself has the advantages of being easy to use with the help of a plain cotton fabric without a pile, which can be polished well when wet.

The formulation of the new detergent can be supplemented with other preparations for finishing, which practically do not affect the resulting effective effect, but are usual for the form, appearance and aroma of consumer goods. These include the addition of small amounts of perfumes, dyes, glycol, or ethanolamides to increase foaming or to change the propellant for aerosol packaging. These additional formulations will also be able to adjust the appearance of the formulation according to the application (i.e., the resolution of the product for cleaning car windows, cleaning household windows, aerosol packaging, etc.).

1000 g of a clear yellowish liquid with properties verified by non-application were obtained. The product obtained was tested for window cleaning, with 25 g of product being consumed per 1 m of cleaned area. The cleaning was carried out with a cotton cloth without pile moistened with the prepared cleaning agent. Mechanical cleaning and polishing of the window was done with the same fabric. Very good results were achieved without leaving visible dirt.

Example 2

A 1500 ml flask equipped with a stirrer and a dispensing spout was charged with g of lithium alkyl sulfate of C12 up to a concentration of 40% active ingredient, g of sodium bis-2-ethylhexylsulfosuccinate at a concentration of 50% active ingredient, and

945 g of water.

The obtained fine emulsion-forming liquid product was application-tested for cleaning the formica surfaces. The actual cleaning was performed with a cotton cloth without hair, moistened with the prepared product. Depending on the contamination, the cleaning agent consumption ranged from 20 to g per 1 m @ 2. After flushing with the same fabric (used to wash the soiled umakart area), a glossy surface with no visible stains was achieved.

940 g of water.

The obtained liquid product with slight turbidity was tested for cleaning of enamel surfaces. The actual cleaning was carried out using a cotton cloth moistened with the prepared product. The same fabric was used for polishing the surface. The cleaning agent consumption was 30 g per 1 m ² . Cleaning with this procedure is easy, fast and the cleaned surface was clean and evenly glossy.

Example

To a 1500 ml flask equipped with a stirrer and a dispensing spout were charged 30 g of 40% sodium 2-ethylhexyl sulfate, g of sodium alkyl tetrraglycol ether sulfosuccinate, 5 g of acid, coconut diethanolamide and 940 g of water.

The product obtained (clear liquid) was tested with good results in window cleaning, with 20 g of product being consumed per m ^{2 of} surface to be cleaned. The cleaning was carried out with a cotton cloth moistened with said detergent. Mechanical cleaning and polishing of the cleaned surface was performed with the same fabric.

The product in the aerosol package was used for cleaning car windows. The actual cleaning was carried out by applying a small amount of foam to the window after pressing the sprayer and spreading it with a cotton cloth until completely polished. In addition to a good stain-free surface, a temporary ability to prevent the glass from sweating in winter was obtained after cleaning the inside of the window. This welcome effect is due to the sulfosuccinate content of the product. When cleaning windows, it is important not to use a sponge that makes it impossible to clean and polish the window because of its suction power, but to use fabrics (preferably without hair) or buckskin.
