Definitions

  • the present invention relates to storage-stable, aqueous, concentrated brightener formulations and a process for their preparation and their use.
  • optical brighteners are preferably marketed in the form of aqueous solutions.
  • the moist filter cake or the dry powder is slurried with water.
  • This suspension is mixed with dispersants and thickeners to increase homogeneity, wettability and stability.
  • An electrolyte is often added to these auxiliaries.
  • the additives used up to now could not prevent sedimentation of the brighteners over a longer period of time.
  • Such formulations preferably contain anionic optical brighteners which contain at least one sulfonic acid residue.
  • they are brighteners of the triazine series of the formula: wherein X and Y, which may be the same or different and represent a secondary or tertiary amine radical or a mono- or di-substituted alkoxy group, and M represents a hydrogen atom or a salt-forming cation.
  • Optical brighteners from the distilbene range can also be used.
  • A sulfonic acid residue, hydrogen, C 1 -C 4 alkyl, C 1 -C 4 alkoxy or halogen
  • 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 fluorine, chlorine and bromine, but especially chlorine.
  • C 1 -C 4 alkyl radicals come straight and branched alkyl radicals such as the methyl, ethyl, n- and iso-propyl, n-, sec- and tert-butyl radicals into consideration.
  • These C 1 -C 4 alkyl radicals can 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.
  • Preferred amine salt ions are those of the formula H + NR 8 R 9 R 10 in which Rg, R 9 and R 10 independently of one another are hydrogen, alkyl, alkenyl, hydroxyalkyl, cyanoalkyl, haloalkyl or phenylalkyl or in which R 8 and Rg together are the addition represent 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 the cation M is an alkali metal, ammonium or amine ion, potassium and sodium being of particular importance for practical reasons.
  • the anionic polysaccharides which can be used according to the invention belong to the group of modified polysaccharides which can be derived from cellulose. It can be etherified cellulose, but also heteropolysaccharides that contain other monosaccharides in the side chains, e.g. Mannose and glucuronic acid included.
  • the anionic polysaccharide is, for example, Na carboxymethyl cellulose and particularly preferably xanthan.
  • the amount of polysaccharide is preferably 0.01 to 1% by weight, a range of 0.05-0.5% by weight being particularly preferred, based on the total weight of the formulation. However, with very highly concentrated or very low concentrated formulations, these ranges can be exceeded.
  • the formulation can contain auxiliaries; Examples include electrolytes, preservatives such as chloroacetamide or aqueous formaldehyde solution and odor improvers.
  • the electrolyte can be sodium chloride, sodium sulfate, sodium carbonate or one of the corresponding potassium salts or also mixtures of the aforementioned substances.
  • the amount of electrolyte can be 0.1 to 25% by weight, based on the total weight of the formulation, preferably 0.1 to 20% by weight.
  • Formulations according to the invention are obtained by mixing the moist filter cake or the dry powder of an anionic optical brightener, which preferably contains at least one sulfonic acid residue, in an amount of 10-60% by weight, based on the total weight of the formulation, with 0.01-1% by weight % anionic polysaccharide and water mixed and homogenized.
  • an anionic optical brightener which preferably contains at least one sulfonic acid residue
  • the desired content of anionic optical brightener in the suspension can be adjusted either by adding water, aqueous electrolyte, suspension or further dry powder to the moist filter cake. This setting can be made before, during or after the addition of the anionic polysaccharide.
  • the proportion of the anionic optical brightener is expediently 10 to 60%, preferably 15 to 40% by weight, based on the weight of the suspension.
  • the suspension is then mixed with the anionic polysaccharide until it is homogeneous.
  • the formulation can be incorporated into a detergent, e.g. by allowing the required amount of the suspension to flow from a container into a mixing device which contains a suspension of the detergent or detergent.
  • the present invention accordingly also relates to a process for the production of detergents, and to the detergents obtained thereafter, characterized in that a suspension for detergents of conventional detergents is mixed with an inventive suspension of brighteners, and dried.
  • the suspensions obtained are advantageously dried by subjecting them to a spray drying process.
  • the brightener formulation according to the invention can be used for the production of liquid detergents.
  • the properties of the brightener formulation correspond to those from Example 1.
  • the brightener formulation does not form any deposits after standing for several months at room temperature and 40 ° C.
  • the brightener formulation is stable on storage at room temperature and 40 ° C.
  • the suspension shows no deposits after standing for 3 months at room temperature.
  • the brightener formulation is stable on storage at room temperature and 40 ° C.
