Abstract
Described herein is a hair treatment composition including one or more fluorescent compounds. 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.

1) A hair treatment composition comprising one or more fluorescent compounds, the one or more fluorescent compounds each comprising:
- i. a fluorophore;
- ii. one or two permanent cations, wherein the permanent cations are pendant to the fluorophore or part of the fluorophore, and wherein the fluorophore and the permanent cations form a core structure;
- and
- iii. one to four incipient cations, wherein each of the one to four incipient cations is pendant via a linker group to the core structure, and wherein the incipient cations are neutral;
- iv. one or more C5-C9 hydrophobes, wherein the one or more C5-C9 hydrophobes are pendant to the core structure;
- wherein the hair treatment composition has a pH of from about 7 to about 11.
