   In der Patentschrift Nr. 36807 und in der deutschen Patentschrift Nr. 200914 sind Verfahren zur Herstellung von haltbaren, insbesondere für die   Orientkupe geeigneten, kon-   zentrierten Indigweiss- bzw. Indigweisssalzpräparaten beschrieben worden, darin bestehend, dass man Indigweiss- bzw. Indigweissalkali mit Melasse, Sirup,   Zuckerqrten   oder deren technischen Ersatzprodukten mischt und gegebenenfalis durch Verdampf ing konzentriert oder zur   völligen Trockne   bringt. 



   Es wurde nun gefunden, dass an Stelle obengenannter   Körper Milchsäure bzw. milch-   saure Salze mit Vorteil dem Indigweiss bzw. dessen Salzen einverleibt werden können. 



  Gegenüber dem Verfahren des Stammpatentes bedeutet das vorliegende Verfahren insofern einen technischen Fortschritt, als bei Verwendung von   Milchsäure   oder milchsauren Salzen, welche beide sirupöse, wasserlösliche und in wasserhaltigem Zustande das Wasser schwer abgebende Flüssigkeiten bilden, es möglich ist, noch geringere Mengen zuzusetzen, als es bei Verwendung der in der   österreichischen   Patentschrift Nr. 36807 und deutschen Patentschrift Nr. 200914 genannten sirupösen, wasserlöslichen, neutralen an sich gürungsfähigen

   In patent specification No. 36807 and in German patent specification No. 200914, processes for the production of long-lasting, particularly suitable for the oriental cup, concentrated indigweiss and indigweiss salt preparations have been described, consisting of indigweiss or indigweiss alkali with molasses , Syrup, sugar crops or their technical substitute products and, if necessary, concentrated by evaporation or brought to a complete dryness.



   It has now been found that instead of the abovementioned bodies, lactic acid or lactic acid salts can advantageously be incorporated into the indigo white or its salts.



  Compared to the process of the parent patent, the present process represents a technical advance insofar as when using lactic acid or lactic acid salts, which both form syrupy, water-soluble and water-poor liquids in a water-containing state, it is possible to add even smaller amounts than it is when using the syrupy, water-soluble, neutral gurable per se mentioned in Austrian patent specification No. 36807 and German patent specification No. 200914
