  Described herein is a hair treatment composition for the hair. The hair treatment composition includes one or more fluorescent compounds and one or more additional ingredients. The one or more fluorescent compounds each include a fluorophore, one or two permanent cations, and one to four incipient cations. The one to four incipient cations are pendant to the core structure and are neutral. The one or more fluorescent compounds enter the hair shaft after the hair treatment composition is applied to the hair. The hair treatment composition has a pH of from about 7 to about 11.

  本文描述了一种用于头发的头发治疗组合物。该头发治疗组合物包括一个或多个荧光化合物和一个或多个额外的成分。其中一个或多个荧光化合物每个包括一个荧光团、一个或两个永久阳离子和一个到四个潜阳离子。这一到四个潜阳离子是挂接在核心结构上的中性离子。在头发治疗组合物被应用到头发后，这一个或多个荧光化合物进入了头发内部。该头发治疗组合物的pH值在约7到约11之间。

  Described herein is a method of treating the hair. The method includes applying to the hair a hair treatment composition including one or more fluorescent compounds and rinsing the hair with water. The one or more fluorescent compounds each include a fluorophore, one or two permanent cations, and one to four incipient cations. The incipient cations are pendant to the core structure and are neutral. The one or more fluorescent compounds enter the hair shaft after the hair treatment composition is applied to the hair The hair treatment composition has a pH of from about 7 to about 11. The pH of the hair after rinsing is from about 3.5 to about 6. The rinsing of the hair causes one or more of the one to four incipient cations to change from neutral to positively charged inside of the hair shaft.

  本文描述了一种处理头发的方法。该方法包括将含有一种或多种荧光化合物的头发处理组合物涂抹在头发上，并用水冲洗头发。其中，每种荧光化合物包括一个荧光团、一到两个永久阳离子和一到四个悬挂于核心结构的中性潜阳离子。一种或多种荧光化合物在头发处理组合物被涂抹在头发上后进入头发内部。头发处理组合物的pH值在约7至约11之间。冲洗头发后头发的pH值在约3.5至约6之间。冲洗头发会导致一到四个中性潜阳离子在头发内部变为带正电荷的阳离子。
