Description

FIELD OF THE INVENTION The present invention relates to a composition for cleaning bathroom and kitchen fixtures which, in addition to anionic and nonionic surfactants, is an adsorptive and mechanical cleaning fine particulate solid, alkaline active ammonia, dispersant alkaline phosphate and optionally bactericidal, coloring, foaming contain.

The increase in the range of detergents makes it possible to select a composition which is suitable for a particular application. The composition of the compositions is determined by the material quality and nature of the surface to be cleaned, the composition of the dirt to be removed and the degree of soiling.

The requirement for bathroom cleaners is extremely complex. The product should remove impurities consisting of scale, soap residues, grease or oil components. These alone cause hard to remove deposits on enamel surfaces, tiles, fixtures, fittings made of plastic, chrome-plated copper and stainless steel. Other unpleasant phenomena may be the deposition of various microorganisms, fungi and algae on the deposits thus formed.

The formulation should rapidly and efficiently remove complex contamination, prevent biological contamination, and at the same time protect the treated surface and the skin of the user's hand.

Acidic cleaners are primarily suitable for the removal of scale. This use of inorganic acids is hampered by their aggressive action on enamel surfaces and metal components. Organic acids (such as tartaric acid, acetic acid, citric acid), which are suitable for efficiently dissolving limescale deposits, are less aggressive, but their longer use causes matting of enameled surfaces and can cause corrosion in enamel defects (eg bathtubs). These adverse effects can also be partially offset by the use of inhibitors, as disclosed in European Patent Application No. 137,475, which mentions the use of ethylenediaminetetraacetic acid sodium salt in addition to citric acid.

The use of acidic compositions for cleaning enameled surfaces in the domestic market is not recommended for these reasons. In addition, organic acids are unsuitable for dissolving soap deposits and their use is limited due to incompatibility with various ionic surfactants.

When using alkaline compositions, the difficulty is the removal of scale. The alkaline components do not dissolve the scale, but at most help disperse the loosened sediment. These agents, on the other hand, prefer to dissolve greasy, oily impurities. It is also difficult to remove calcium soap that is hard due to hard water due to hard water. These composite impurities can be removed by alkaline formulations which, in addition to surfactant combinations, also contain dispersants and finely divided solid components with mechanical abrasive action.

Removing heavily soiled kitchen equipment, especially stove and oven greasy oily deposits, requires a similarly complex cleaning agent. In most cases, these compositions contain free alkali metal hydroxide. Fine-grained, solid mechanical abrasives are also used in this type of cleaning agent.

Bathroom and kitchen cleaners with alkaline and mechanical cleaning effects are characterized by the following components.

The surfactant is generally an alkyl salt of alkylbenzenesulfonic acid, ethoxylated nonylphenol, ethoxylated fatty alcohol sulfate, or olefin sulfonate. At least one of the surfactants listed is present in all known detergent compositions.

The free sodium hydroxide component is disclosed in Japanese Patent 60141797 (C.A. / 03 197723η).

Various clay minerals, nepheline or montmorillonite, mentioned in U.S. Patent No. 60,108,500 (C.A. 103,162,234b), and titanium dioxide as disclosed in U.S. Pat. European Patent Application No. 4,477,365; U.S. Patent No. 4,664,104 to Calcium Carbonate; French patent application.

No. 185,448. In the Hungarian patent, besides the qualified secondary alkanesulfonic acid salt - alkylphenol-polyglycol ether - fatty acid-ethanolamide surfactant, limestone flour abrasive is used specifically for hand cleaning purposes.

Of the listed cleaners, free sodium hydroxide is aggressive and also corrosive to the skin. Those containing clay powder have good slurry stability, settle slowly, but their mechanical cleaning effect is unsatisfactory. Ultra-pure calcium carbonate or titanium dioxide is used in white, high-quality, more expensive cleaners.

In addition to overcoming the disadvantages of the known detergents, the present invention provides a good combination cleaning, non-aggression, hand-protecting and biological anti-infective agent for use in bathrooms and kitchens. as a dispersant, trisodium phosphate and / or sodium tripolyphosphate, as solid particulate matter kaolin or alumina, in addition active ammonia and, optionally, cetylpyridinium bromide and / or copper tetramine salt as a biocide, contains fragrance.

A further requirement for a multi-component system is the use of quantitative proportions such that each component has a solubility or solubility ratio. in suspension at compatible concentrations consistent with their stability

HU 206 392 Β present. The basic requirement for such formulations is to give the product a pleasing appearance, which can be achieved by providing a suitably stable, slow-settling suspension and providing a harmonious color and fragrance.

It has been found that when a linear (soft) sodium dodecylbenzenesulfonic acid sodium salt used in similar cleaning agents and a nonylphenol surfactant ethoxylated with 9-10 ethylene oxide units are further combined with 13-15 ethylene oxide units ethoxylated C 10-18 fatty alcohol and / or by adding an average of 18 carbon atoms of an unsaturated, natural fatty acid mixture to the acaric sarcosine salt, the resulting surfactant mixture is mixed with the phosphate-type dispersant as a real solution in water to maintain a stable, hard-to-settle suspension. The resulting thick slurry has a more advantageous compound cleaning effect over known formulations. In addition to the basic cleaning effect, additional additives provide additional beneficial properties of the compositions. Thus, free ammonia helps loosen difficult-to-remove greasy impurities, but is less corrosive than sodium hydroxide. In bathrooms, bacterial, fungal, algae infections that often settle on deposits are prevented by the addition of cetylpyridinium bromide and / or copper tetramine salts. Occasionally, a coloring agent and / or coloring agent may be desirable. perfume composition.

The preparation is carried out in a stirred vessel in which the required amount of water is added, followed by dissolution of the trisodium phosphate and / or sodium tripolyphosphate with stirring. The dodecylbenzenesulfonic acid sodium salt is added as a 48% aqueous paste and stirred. The resulting viscous solution is mixed with ethoxylated nonylphenol, ethoxylated fatty alcohol and / or N-acyl sarcosine salt and then mixed with kaolin and / or alumina. After stirring the stable suspension, ammonia is added in aqueous solution, followed by cetylpyridinium bromide in pre-prepared warm aqueous solution and / or copper tetramine salt in pre-prepared aqueous ammonia solution, and finally the dye and saliva composition. The antifoam alcohol may be added during the formulation if necessary.

The bathroom and the bathroom. The composition of kitchen cleaners is modified by varying the proportions of the listed ingredients to some extent. Thus, a less alkaline and abrasive effect in bathroom detergents is desirable to protect more sensitive enamel and polished metal surfaces, while the use of a biocidal agent is more demanding. More alkalinity, more intense mechanical abrasion and a stronger liposolubility are desirable than kitchen detergent compositions. In accordance with the present invention, formulations suitable for these two areas can be formulated within the lower and upper limits of the amount of each component.

The composition according to the invention comprises 4-81% linear (soft) sodium salt of dodecylbenzenesulfonic acid, 2-6% nonylphenol ethoxylated with 9-10 ethylene oxide units, 1-2% 10-15% ethoxylated ethylene oxide with 13-15 ethylene oxide units. C18 fatty alcohol and / or 0.5-61% sarcosine salt acylated with an average C18 unsaturated natural fatty acid mixture, 2-8% trisodium phosphate and / or sodium tripolyphosphate, 0.1-04% ammonia, 5-15% Kaolin and / or alumina mills with a particle size of 20100 pm, optionally 0.05-0.11% cetylpyridinium bromide and / or 0.1-0.41% copper tetramine salt, 0.001-0.0111% water-soluble colorant, and 0.01-0.06% by weight of a perfume composition in water to provide a volume of 100% by weight of the composition. To facilitate foaming of the composition, 0.5 to 2% of a C 1-4 monovalent alcohol is optionally added to reduce foaming.

The following examples illustrate the preparation and advantageous use of our composition.
