Definitions
- the invention relates to a builder component with a very high bulk density and to detergents or cleaning agents which contain this component.
- both ⁇ - and ⁇ '-sodium disilicate Na2Si2 ⁇ 5 * yH2 ⁇ are preferred, wherein ⁇ -sodium disilicate can be obtained, for example, by the process described in international patent application WO-A-91/08171.
- ⁇ -sodium disodium is available under the name SKS 7 ( R )
- fr-sodium disilicate is commercially available under the name SKS ⁇ ( R ) (commercial products from Hoechst AG, Federal Republic of Germany).
- These powders generally have a bulk density of less than 600 g / l and have a high proportion of fine particles, usually more than 30% by weight, with a particle size of less than 0.1 mm.
- crystalline layered silicates can suffer losses in their washing action when spray-drying slurries containing detergents or cleaning agents, they should preferably be incorporated into detergents or cleaning agents by other process methods. Because of their low bulk density, however, the powders are not very suitable for being mixed into modern washing or cleaning agents with high bulk densities of at least 650 g / l. If they are mixed in anyway, segregation occurs in most cases due to the high proportion of fine grains of the crystalline layered silicates.
- the object was therefore to provide a preparation form for crystalline layered silicates which has high bulk densities and essentially no fine-grain fractions with particle sizes below 0.1 mm and with liquid preparation forms, the ingredients of which are essentially components of conventional detergents or cleaning agents and preferably also pose problems in spray drying, is impregnated.

- Aqueous surfactant pastes can be of particular interest if the water is subsequently dried away. In the case of aqueous surfactant pastes, the quantitative data given above for the impregnating agent relate either to the paste if the water is not or not completely dried off, or to the surfactant active substance of the paste if the water is dried away.
- Suitable impregnating agents are, for example, advantageously ethoxylated, in particular primary, alcohols which are liquid under the process conditions and preferably have 8 to 18 carbon atoms and an average of 1 up to 12 moles of ethylene oxide (E0) per mole of alcohol, in which the alcohol radical can be methyl-branched linearly or preferably in the 2-position, or can contain linear and methyl-branched radicals in the mixture, as are usually present in oxo alcohol radicals.
- alcohol ethoxylates with linear residues of alcohols of native origin with 12 to 18 carbon atoms, for example from coconut, palm, tallow or oleyl alcohol, and an average of 2 to 8 EO per mole of alcohol are particularly preferred.
- the preferred ethoxylated alcohols include, for example, C 1 -C 4 alcohols with 3 EO or 4 EO, Cg-Cn alcohol with 7 EO, Ci3-Ci5 alcohols with 3 EO, 5 EO, 7 EO or 8 EO, C ⁇ -Cig alcohols with 3 EO, 5 EO or 7 EO and mixtures thereof, such as mixtures of Ci2-Ci4 alcohol with 3 EO and Ci2 ⁇ Ci8 alcohol with 5 EO.
- the degrees of ethoxylation given represent statistical mean values, which can be an integer or a broken number for a special product.
- Preferred alcohol ethoxylates have a narrow homolog distribution (narrow range ethoxylates, NRE).
- nonionic surfactants are therefore preferably not processed via a spray drying process, but rather via the impregnated builders components according to the invention.
- alkyl glycosides of the general formula R0 (G) x can also be used in particular as further nonionic surfactants, in which R is a primary straight-chain or methyl-branched, in particular methyl-branched aliphatic radical having 8 to 22, preferably 12 to 18, Atoms means and G is the symbol which stands for a glycose unit with 5 or 6 carbon atoms, preferably for glucose.
- the degree of oligomerization x which indicates the distribution of monoglycosides and oligoglycosides, is any number between 1 and 10; x is preferably 1.2 to 1.4. They are preferably used in the form of an aqueous paste.
- Suitable surfactants which are used instead of or together with the alkylglycosides are polyhydroxyfatty acid amides of the formula (I),
- R ⁇ CO for an aliphatic acyl radical with 6 to 22 carbon atoms
- R3 for hydrogen, an alkyl or hydroxyalkyl radical with 1 to 4 carbon atoms
- [Z] for a linear or branched polyhydroxyalkyl radical with 3 to 10 carbon atoms and 3 is up to 10 hydroxyl groups.

- Esters of oc-sulfofatty acids or the disalts of ⁇ -sulfofatty acids are also suitable.
- Other suitable anionic surfactants are sulfonated fatty acid glycerol esters, which are mono-, di- and triesters and their mixtures, such as those produced by esterification by a monoglycerol with 1 to 3 mol of fatty acid or in the transesterification of triglycerides with 0 , 3 to 2 moles of glycerol can be obtained.
- Suitable surfactants of the sulphate type are the sulfuric acid monoesters from primary alcohols of natural and synthetic origin, in particular from fatty alcohols, for example from coconut fatty alcohol, tallow fatty alcohol, oleyl alcohol, lauryl, myristyl, cetyl or stearyl alcohol, or the C ⁇ o-C2 ⁇ - Oxoalcohols, and those secondary alcohols of this chain length.
- the sulfuric acid monoesters of alcohols ethoxylated with 1 to 6 mol of ethylene oxide, such as 2-methyl-branched Cg-Cn alcohols with an average of 3.5 mol of ethylene oxide, are also suitable.
- anionic surfactants in particular their alkali metal salts such as sodium and / or potassium salts, are used either in the form of an aqueous paste or in a mixture with nonionic surfactants, in particular in a mixture with ethoxylated fatty alcohols. It is also possible to use aqueous pastes which contain both anionic surfactants, in particular alkylbenzenesulfonates and / or alkyl sulfates, and nonionic surfactants, in particular ethoxylated fatty alcohols and / or alkylglycosides.
- alkyl sulfates are particularly preferred because alkyl sulfates still contain unreacted alcohol from their production, which leads to visible pluming problems when spray drying large amounts of alkyl sulfate. Alkyl sulfates are therefore preferably not over one Spray drying process, but processed via the impregnated builders components according to the invention.
- the impregnated builder components according to the invention preferably have a bulk density of above 800 g / 1 and in particular above 900 g / 1, the bulk weight of the impregnated builder component being in any case higher than the bulk weight of the granular crystalline sheet silicate used.

- the builder components according to the invention can advantageously be produced by a process using crystalline sheet silicates in granular form with bulk densities above 650 g / l, which are produced by roller compaction and then by grinding and sieving and then treated with an impregnating agent.
- the roller-compacted crystalline layered silicates are used at least in amounts of 60% by weight, based on the impregnated builders component.
- the builder components are then powdered and in particular powdered with powdery crystalline layer lates.
- the invention relates to a washing or cleaning agent which contains the builders components according to the invention.
- these agents preferably contain the builder components according to the invention in amounts of 10 to 70% by weight and in particular in amounts of 20 to 60% by weight.
