Abrasives

The present invention relates to abrasives and especially abrasives containing monopersulphate as an oxidizing bleach.

It has been found that the stain removing effect of Abrasives, which monopersulphate as an oxidizing bleach contain, through the addition of small amounts of water-soluble bromides can be significantly improved v / ground. So Abrasives which contain water-soluble bromides are characterized by an extremely fast and complete process Effect in removing stains and dirt as well as through oxidizing and disinfecting effect. These effects are much larger than they are due to the comparable chlorides be achieved. In addition, these abrasives, in contrast to the hypochlorite or chlorine-releasing substances (such as water-soluble chlorides) containing known abrasives in the unscented state has a pleasant, practically non-irritating odor, which affects both use with water as well as the smell it leaves on consumers' hands. Since the inventive

if abrasives do not contain hypochlorites, leave them also easier with common essential oils and Perfume perfume ingredients. Furthermore, these new abrasives are extraordinarily storable and self-sufficient especially for polishing fogged or stained metal surfaces and for removing stains or deposits made of soft material such as aluminum from porcelain surfaces.

With the invention thus abrasives are proposed which at least about mm 6o% wt. Water-insoluble inorganic siliceous abrasive having a particle size (diameter) of less than about 0.5, about 0.1 to 20 wt.% Alkalimonopersulfat, about 0.5 to water-soluble 15 wt.%, in the presence of the monopersulfate largely resistant washing-active substance and water-soluble bromide% about 0.1 to 10 wt..

Those which can be used for the abrasives according to the invention Abrasives consist of silica-containing substances such as quartz, feldspar, pumice stone, volcanic ash, Diatomaceous earths, bentonite and talc and mixtures thereof. For general purposes, quartz or feldspar are preferred used because they are relatively hard and give a relatively white product. Abrasives of different

The hardness, particle size and particle shape used and the choice of abrasive for a particular abrasive will generally depend on the intended use of the abrasive. The particle size of the abrasive should be less than 0.5 mm and, in general, substantially all of the abrasive should have a maximum particle size of about 0.15 minutes. Usually abrasives are used which pass at least about 85% by weight and preferably 99% by weight through a sieve with a mesh size of 0.07 mm. On the other hand, it is advantageous to obtain a good cleaning effect when at least 8 wt.% Of the abrasive particles have a diameter of about 0.037 MRA or above. The abrasives according to the invention contain, based on the total product, at least about 60% by weight and preferably at least about 85 to 95% by weight of abrasive.

The alkali monopersulfate used in the scouring agents according to the invention is preferably the potassium or sodium salts, which are available as commercial products. The potassium salt is particularly preferred and can optionally be used in the form of a triple salt with potassium bisulfate and potassium sulfate, for example as KHSOc * KHSO ^ 'K ₂ SO ₂ J _- in ^a molar ratio of about 2: 1: 1.

The third important component of the invention Abrasive agent is a water-soluble organic washing active ingredient, which in the presence of the monopersulfate used is constant. There can be anion-active, cation-active, amphoteric or nonionic detergent active ingredients are used, provided that they are used with the total product in the specified Quantities are compatible. If they exist as liquids under normal conditions, as is the case with the nonionic substances is generally the case, they can in a known manner after adsorption on diatomaceous earth or similar substances are brought into solid particle form.

Sicti are suitable as anion-active washing active substances for the inventive Products for example the soaps and the sulfated and sulfonated synthetic detergents, especially those having about 8 to 26, and preferably about 12 to 22 carbon atoms in the molecule. The water-soluble salts of saturated higher fatty acids and fatty acid mixtures are generally used as soaps used.

The sulfated and sulfonated detergents are ai, f dem Detergent area also known and can be made from suitable organic substances which are amenable to sulfonation (true sulfonation and / or sulfation), getting produced. Of the numerous suitable sulfates and sulfonates, preferred are the aliphatic sulfates and sulfonates having about 8 to 22 carbon atoms and the alkyl aromatic sulfonates are used.

The alkyl aromatic sulfonates mentioned can consist of mononuclear or polynuclear compounds. The aromatic nucleus can be derived from benzene, toluene, xylene, phenol, cresols, phenol ethers, naphthalene, derivatives of phenanthrene nuclei and the like. Likewise, the alkyl group can also have different properties. It can, for example, be straight-chain or branched and made up of residues such as dodecyl, pentadecyl, ootyl, I-fijn / L, Dec / 1, keryl or mixed alkylers, dLe sLch of fat, ^) I of inen from cracked puraffin waxes or ¹ polymers

Specifically, examples of suitable alkylaromatic Sulfonates the propylated naphthalene sulfonates that are mixed Butyl naphthalene sulfonates and tetrahydronaphthalene sulfonates and the various butylated diphenyl sulfonates and Phenylphenolsulfonate may be mentioned. Generally will however, the alkyl aromatic sulfonates with higher alkyl substituents preferred to those with lower alkyl substituents. From this group, the alkylbenzenesulfonates are particularly preferred having at least 8, and preferably about 10 to 16 carbon atoms in the alkyl group. Of the Benzene ring can also have other substituents such as alkyl and carry hydroxyl groups.

Further suitable detergent active substances are the sulfated ones or sulfonated aliphatic compounds with preferably 8-22 carbon atoms. These include the sehweric acid esters of polyhydric alcohols which are incompletely esterified with higher fatty acids, such as coconut monoglyceride monosulfate and tallow glyceride monosulfate, the long chain ones

pure or mixed alkyl sulfates such as laurysulfate and cetyl sulfate, the esters of higher fatty acids with low molecular weight alkylolsulfonic acids such as the fatty acid esters of isethionic acid, the fatty acid ethanol amide sulfates, the fatty acid amides of aminoalkyl sulfonic acids such as the lauric acid amide of taurine and the like. In particular, the sulfated aliphatic Compounds with at least about 8 carbon atoms and especially with 12 to about 22 carbon atoms in the molecule are preferred.

Although the anionic detergents are preferred, cationic, nonionic and amphoteric detergents can also be used either as the sole active component or as a Part of the same can be used, provided that it is compatible with the remaining ingredients of the abrasive agents according to the invention are compatible under the storage and use conditions of the same.

Examples of suitable cation-active detergents are the quaternary ammonium compounds with long-chain alkyl substituents called as the quaternary Cety! ammonium salts to which cetyltrimethylammonium chloride and cetylpyridinium chloride belong. Another equally suitable cation-active compound is the diethylenaminoethyloleylamide product.

As non-ionic compounds, which the Facnmann also are known, for example, the polyoxyethylene ethers of alkyl aromatic hydroxy compounds such as the alkylated ones Poloxyethylene phenols, the polyoxyethylene ethers of hydrophobic propylene oxide polymers and higher alkylamine oxides such as lauryldimethylamine oxide.

As examples of suitable amphoteric detergents, the Salts of higher alkyl-ß-aminopropionic acids, e.g. sodium-N-laurylß-alanine, the higher alkyl substituted betaines such as lauryldimethylamraonium acetic acid and imidazoline-type compounds such as the disodium salt of 1- (, 2-hydroxyethyl) -1- (carboxymethyl) -2- (undecyl) -4,5-dihydroimidazolinium hydroxide to be named.

The anion-active and cation-active surface-active compounds are generally used in the form of their water-soluble salts. The synthetic anion-active compounds are the alkyl salts such as the sodium and potassium salts are preferred, but other salts such as the ammonium, Amine, alkylolamine and alkaline earth salts (e.g. calcium and magnesium salts) can be used. In the case of the cation-active compounds, the chlorides, sulfates and acetates are expedient and similar salts are used.
