摘要： The present invention is directed to the preparation of an aqueous hair dyeing composition containing an effective hair dyeing amount--at least 2 mg/ml--5,6-dihydroxyindole (DHI). An aqueous hair dyeing composition is produced by reacting under essentially anaerobic conditions dopa or a salt thereof with an alkali metal ferricyanide oxidant in an aqueous reaction medium to obtain dopachrome, and permitting the dopachrome to undergo rearrangement in the aqueous medium to form 5,6-dihydroxyindole, said rearrangement being conducted in the substantial absence of oxidant, the aqueous medium being buffered by sufficient buffering agent to maintain a pH of from about 4.5 to about 9 for the reaction medium throughout the series of reactions that take place thereafter, removing the ferrocyanide species present in the aqueous system, and lastly, charging the composition into a suitable container.
摘要翻译：本发明涉及含有有效染发剂量至少2mg / ml-5,6-二羟基吲哚（DHI）的含水染发组合物的制备。通过在基本上厌氧条件下使多巴或其盐与碱金属铁氰化物氧化剂在水性反应介质中反应来制备水性染发组合物，以获得多巴色素，并允许多巴色素在水性介质中重排以形成5,6- 所述重排在实质上不存在氧化剂的情况下进行，所述水性介质通过足够的缓冲剂缓冲，以在其后发生的一系列反应中为反应介质保持pH为约4.5至约9，除去亚铁氰化物存在于水体系中的物质，最后，将组合物装入合适的容器中。
