The invention provides compositions and methods for the oxidative coloring of human hair. The compositions of the invention contain as a primary dye intermediate a 1-(4-aminophenyl) pyrrolidine, or a cosmetically acceptable salt thereof. The compositions may also contain at least one other primary intermediate and conventional coupling compounds, in addition to an oxidizing agent and other components typically used in oxidative hair dye preparations. Preferred dye intermediates in the compositions of the invention include 1-(4-aminophenyl) pyrrolidine and 1-(4-amino-3-methylphenyl) pyrrolidine, or cosmetically acceptable salts thereof, which produce intense neutral colors when used in admixture with a suitable coupling agents, such as 3-aminophenol, in conventional hair dye base formulations.
本发明提供了对人类头发进行氧化染色的组合物和方法。本发明的组合物含有 1-(4-氨基苯基)吡咯烷或其美容上可接受的盐作为初级染料中间体。除了氧化剂和氧化染发制剂中通常使用的其他成分外,组合物中还可能含有至少一种其他主中间体和常规偶联化合物。本发明组合物中优选的染料中间体包括 1-(4-氨基苯基)吡咯烷和 1-(4-氨基-3-甲基苯基)吡咯烷,或它们在化妆品上可接受的盐,当它们与合适的偶联剂(如 3-氨基苯酚)混合用于常规染发剂基料配方中时,可产生强烈的中性色。
