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, one to four incipient cations, and one or more hydrophobic moieties. 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于头发上,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、一到四个潜在阳离子和一个或多个疏
水基团。潜在阳离子悬挂于核心结构上并且是中性的。在将头发处理组合物涂抹于头发后,一种或多种荧光化合物进入了头发内部。头发处理组合物的pH值在约7到约11之间。清洗头发后,头发的pH值在约3.5到约6之间。冲洗头发会导致一到四个潜在阳离子在头发内部从中性变为带正电荷。
