Description

Die vorliegende Erfindung betrifft lagerstabile, wässrige, konzentrierte Aufhellersuspensionen und ein Verfahren zu deren Herstellung sowie deren Verwendung.The present invention relates to storage-stable, aqueous, concentrated Whitener suspensions and a process for their preparation and their Use.

Heutzutage werden optische Aufheller bevorzugt in Form wässriger Lösungen in den Handel gebracht. Hierzu wird der feuchte Filterkuchen oder auch das trockene Pulver mit Wasser aufgeschlämmt. Diese Suspension wird mit Dispergatoren und Verdickungsmitteln zur Erhöhung von Homogenität, Benetzbarkeit und Stabilität versetzt. Zu diesen Hilfsstoffen setzt man häufig noch einen Elektrolyten hinzu. Die bisher verwendeten Hilfsstoffe konnten jedoch ein Sedimentieren der Aufheller nicht über einen längeren Zeitraum verhindern.Nowadays, optical brighteners are preferred in the form of aqueous solutions in brought the trade. For this purpose, 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. Often, an electrolyte is added to these auxiliaries. However, the adjuvants used so far could sediment the brightener Do not prevent for a long period of time.

Es wurde nun überraschenderweise gefunden, dass man lagerstabile, konzentrierte, wässrige Aufhellersuspensionen erhält, wenn man zu der wässrigen Suspension derartiger Aufheller Xanthan in geringen Mengen zugibt. Derartige Suspensionen setzen sich während der Lagerung kaum ab. Zusätzlich zu dem guten Sedimentationsverhalten bleiben die Suspensionen während der Lagerung homogen.It has now surprisingly been found that storage-stable, concentrated, aqueous brightener suspensions, when added to the aqueous Suspension of such brightener xanthan gum in small amounts admits. such Suspensions hardly settle during storage. In addition to that good sedimentation behavior, the suspensions remain during storage homogeneous.

Die Suspensionen gemäss der Erfindung sind demnach gekennzeichnet durch einen Gehalt an:

  • a) 10 bis 60 Gew.%, bezogen auf das Gesamtgewicht der Aufhellersuspension eines anionischen optischen Aufhellers,
  • b) 0,01 bis 0,5 Gew.% eines anionischen Polysaccharids, welches Xanthan ist, bezogen auf das Gesamtgewicht der Aufhellersuspension und
  • c) Wasser; sowie gegebenenfalls
  • d) Hilfsstoffe.
    • The suspensions according to the invention are accordingly characterized by a content of:
  • a) 10 to 60% by weight, based on the total weight of the brightener suspension of an anionic optical brightener,
  • b) from 0.01 to 0.5% by weight of an anionic polysaccharide which is xanthan, based on the total weight of the brightener suspension and
  • c) water; and optionally
  • d) excipients.
