Definitions

• the present invention relates to storage-stable, aqueous, concentrated Whitener suspensions and a process for their preparation and their Use.
• optical brighteners are preferred in the form of aqueous solutions in brought the trade.
• the wet filter cake or the dry Powder slurried with water This suspension is mixed with dispersants and Thickeners to increase homogeneity, wettability and stability added.
• an electrolyte is added to these auxiliaries.
• the adjuvants used so far could sediment the brightener Do not prevent for a long period of time.
• such formulations contain anionic optical brighteners which contain at least one sulfonic acid residue.
• X and Y which may be the same or different and denote a secondary or tertiary amine group or a mono- or di-substituted alkoxy group
• M represents a hydrogen atom or a salt-forming cation
• X 1 and Y 1 which may be the same or different, have a phenylamino group which is optionally mono- or di-substituted by alkyl groups having 1 or 2 carbon atoms, the morpholino group, an alkylamino group having 1 to 4 carbon atoms substituted by hydroxyl groups may represent an alkoxy group having 1 to 4 carbon atoms, and M represents hydrogen or a salt-forming cation.
• X 2 and Y 2 which may be the same or different, are the phenylamino, the morpholino, an alkylamino group having 1 to 4 carbon atoms which may be substituted by hydroxyl groups and M is hydrogen or a salt-forming cation.
• X 3 and Y 3 which may be the same or different, represent a phenylamino, morpholino, N-methyl-N-ethanolamine group and M represents hydrogen or a salt-forming cation.
• X 4 and Y 4 which may be the same or different, mean the morpholino or the N-methyl-N-ethanolamine group and M is hydrogen or a salt-forming cation.
• M ' represents an alkali metal ion, wherein in the case of this optical brightener, a content of 4 to 25 wt.%, based on the total weight of the slurry, of a strong electrolyte is suitably present.
• Particularly preferred compounds are compounds of the formula where A, B and n have the above meaning and M is a salt-forming cation.
• halogens are especially fluorine, chlorine and bromine in question, in particular but chlorine.
• C 1 -C 4 -alkyl radicals are unbranched and branched alkyl radicals such as the methyl, ethyl, n- and iso-propyl, n-, sec- and tert-butyl radical into consideration. These C 1 -C 4 -alkyl radicals may in turn be substituted with, for example, aryl (phenyl, naphthyl), C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy, OH or CN groups.
• Salt-forming cations M are, for example, alkali metal, ammonium or amine salt ions.
• amine salt ions those of the formula H + NR 8 R 9 R 10 are preferred in which R 8 , R 9 and R 10 independently of one another are hydrogen, alkyl, alkenyl, hydroxyalkyl, cyanoalkyl, haloalkyl or phenylalkyl or R 8 and R 9 together represent the complement to a 5-7-membered saturated nitrogen heterocycle, which may additionally contain a nitrogen or oxygen atom as a ring member, for example a piperidine, piperazine, pyrrolidine, imidazoline or morpholine ring, while R 10 is hydrogen.
• Preferred distyrylbiphenyl compounds of the formula (X) are those in which Cation M is an alkali metal, ammonium, or amine ion, with practical Considerations of potassium and sodium are of particular importance.
• the amount of xanthan is 0.01-0.5 wt%, with a range of 0.05-0.5 Wt.%, Particularly preferred, based on the total weight of Formulation.

• Formulations according to the invention are obtained by mixing the moist Filter cake or even the dry powder of an anionic optical Brightener, which preferably contains at least one sulfonic acid residue, in one Amount of 10-60 wt.% Based on the total weight of the formulation with 0.01 - 0.5 wt.% Xanthan and water mixed and homogenized.
• the desired content of anionic optical brightener in the suspension can either by adding water, aqueous electrolyte, suspension or further dry powder to the moist filter cake. This setting may be before, during or after the addition of xanthan be made.
• the proportion of the anionic optical brightener is Suitably 10 to 60%, preferably 15 to 40 wt.%, Based on the Weight of the suspension.
• the suspension is then mixed with the xanthan until homogeneous.
• the formulation can be incorporated into a detergent, e.g. by Injecting the required amount of the suspension from a container in a mixing device comprising a suspension of the detergent or the detergent contains.
• the present invention accordingly also relates to a process for the preparation of detergents, as well as the detergent obtained thereafter, thereby characterized in that a suspension for detergents of conventional detergents with a suspension of brightener according to the invention, mixed and dried.
• the resulting suspensions are advantageously dried by placing them in a Subject spray drying method.
