Beschreibung
Zusammenfassung:	The invention relates to a method or preparation for making an effective dye powder by substantial oxidative polymerization of tea polyphenols, Cathechins, Epicathechins, Epicathechingallate, and Epigallocathechin gallate (C, EC, ECG, EGCG), and subsequently separating the fragment, which is enriched in flavones/isoflavones glycosides, with the required color, as well as the required hydrophobicity, to give the desired wash and light fastness, when used as the dye. L'invention concerne un procédé ou une préparation pour fabriquer une poudre de teinture efficace par polymérisation oxydative substantielle de polyphénols de thé, de cathéchines, d'épicatéchines, de gallate d'épicatéchine, et de gallate d'épigallocatéchine (C, EC, ECG, EGCG), puis séparer le fragment, qui est enrichi en glycosides de flavones/isoflavones, avec la couleur requise, ainsi que l'hydrophobicité requise, pour obtenir la solidité souhaitée au lavage et à la lumière, lorsqu'elle est utilisée en tant que teinture.
