Definitions
- the invention relates to a detergent additive with a high content on nonionic surfactants (nonionic surfactants) and fast dissolving power.
- Nonionic surfactants are considered one of the major surfactant components used in powdered detergents and need for this Application due to their liquid consistency on solid carriers be applied in granular form. If one sets granules with high Content of nonionic surfactants to a washing powder, so In many cases, these granules dissolve only very slowly on. The slow dissolution rate is based on the phase behavior of nonionic surfactants in mixtures with water.
- a particularly low solubility is found in mixtures pure bentonite-containing granules and nonionic surfactants. This may be due to the bentonite swelling and acts as a thickener and thus the rapid disintegration prevents the agglomerates.
- detergent additives which are not surfactants, but the solubility of nonionic surfactants on detergent granules or surfactant granules increase.
- these include e.g. Alcohols, glycerin and polyglycols.
- DE-A-196 12 085 describes the use of alkylated polyglycol ethers with 5 to 25 ethylene glycol units, which may be branched in the alkyl radical, to Improving the dissolution rate of nonionic surfactants. But at least 10% of these additives must be used to achieve a large increase in solubility.
- DE-A-196 49 150, DE-A-196 47 609 and DE-A-196 48 504 describe also additives to increase the dissolution rate of particulate detergent formulations in water.
- these additives are crosslinked alkoxylated alcohols, to compounds of at least trihydric alcohols and their alkoxylation products or hydrophobic, alkoxylated, at least trihydric alcohols.

- the anionic surfactants in particular the linear alkylbenzenesulfonates, can be used for the production of granules both in their Acid form can be used as well as in the form of their alkali metal salts.
- the latter are mainly in the form of aqueous pastes commercially. These offer over the acid form of the surfactant, although the Advantage that the pH is not lowered, on the other hand
- water is added to the granules introduced, which is unfavorable to the bearing behavior of Granules in washing powders and in particular detergent tablets can affect. These formulations are therefore after granulation appropriately dried.
- the anionic surfactants in their acid form are, in particular, the linear alkyl sulfonates (LAS).
- LAS linear alkyl sulfonates

- the granulation can be both continuous as well as rudimentary.
- agglomerates can also be produced in a batch process become. Is working after a batch process and is a coating is required, this can be done in a second Step in the same mixer by adding the inorganic Powder and by a short additional mixing step be performed.
- an analogous increase in solubility can be the nonionic surfactant-containing granules by addition of linear Benzylalkylsulfonaten observe when the bentonite with other support materials, such as zeolites or SKS-6, (a sodium layer silicate the company Clariant) combined.
- additional Components may include, for example, sodium carbonate or sodium tripolyphosphate (STPP).
- the bentonite-containing granules it may, if one uses the linear alkylbenzenesulfonic acids, appropriate be added soda to neutralize the acid.
- alkali bentonite as a carrier material shows However, that the alkali content of the bentonite sufficient is up to levels of up to 10% linear alkyl benzene sulfonic acid to neutralize.
- the resulting granules show no or only a slight reduction in the pH value in dependence from the carrier material.
- Corresponding comparative examples show also, that the solubility also in neutralization of the linear Alkylbenzenesulfonic acid during granulation over the pure nonionic surfactant is increased.
- soda contents of ⁇ 20 wt .-% are particularly preferred.
- zeolite with linear alkylbenzenesulfonic acid Granulated in the surfactant system so must also be noted be that when using zeolites as support materials solubilization or dissolution of the zeolite may occur when high Contents of linear alkylbenzenesulfonic acid can be used.
- the granules with high content of nonionic surfactants have the advantage of a very high solubility. This makes additions as dispersants, as described in WO 99/36493 were superfluous. It also turns out that these Granules without additives to so-called structuring agents such. Soaps, get along (see WO 99/46395). These can be experienced difficult to incorporate into liquid surfactant mixtures.
- the avoidance of these additives allows the content of nonionic Surfactants, based on certain carrier mixtures on increase as well as the addition of expensive excipients that no Contribute to the washing performance, avoid. dispersants, like microcrystalline cellulose have no positive Influence on the cleaning effect of a washing powder. In contrast, leads the bentonite in such surfactant-containing granules to an improvement of the soft touch and to a reduction the graying of the laundry.
- Agglomerates were, unless stated otherwise, an Eirich intensive mixer R02E used. This was the low setting (Level 1) for the rotational speed of the plate as well as the maximum speed of rotation for the swirler selected.
- Level 1 the low setting for the rotational speed of the plate as well as the maximum speed of rotation for the swirler selected.
- the agglomeration parameters were, if not otherwise specified below, each chosen so that more than 50% by weight of the granules in a particle size range of 0.4 up to 1.6 mm.

- inorganic powders e.g. Talc or zeolites coated.
- the following methods were used: After a first variant, the material was in a plastic bag whereupon the inorganic powder is added and shaken for about 2 minutes. After another Variant, the coating was performed in the Eirich mixer. To after agglomeration, the inorganic powder for coating became was added, after which the agglomerate / powder mixture again 20 up to 30 seconds at 50% of the maximum swirler speed was mixed.
- the total surfactant content is virtually independent from the surfactant composition.
- sample a) shows are the granules made from Laundrosil® DGA and Genapol® OA 070 poorly soluble according to the test method described above.
- the solubility value is only 24%.
- Comparative samples g) and h) show in the case of bentonite as carrier material without addition of linear alkylbenzenesulfonates, that the solubility of the granules in nonionic surfactants by the addition of polyglycols of the prior art although increased; However, these have the disadvantage that they have no Have function in the washing process.
- Laundrosil® DGA / Soda mixtures with different soda contents was made with pure Genapol OA 070 as well as with Genapol OA 070 with an addition of 10 wt .-% Ufacid K agglomerated.
- the results of the experiments are listed in Table III.
- the table shows that by adding in particular 10% by weight of Ufacid® K to the nonionic surfactant Genapol® OA 070, it is possible to obtain agglomerates which have a significantly higher solubility than the agglomerates containing 100% by weight of nonionic surfactant.
- the table further shows that up to 10% by weight of soda can be incorporated into the agglomerates without the surfactant content or the solubility significantly changing with additions of 10% by weight of Ufacid® K.
