A stable, aqueous composition containing a substantially crosslinked alkali-swellable
acrylate copolymer rheology modifier, a surfactant, an alkaline material, and various
compounds therein, as for example substantially insoluble materials requiring suspension
or stabilization, such as a silicone, an oily material, or a pearlescent material.
Additionally, this invention also relates to the formation of a rheologically and
phase stable cationic hair dye composition. The invention further relates to the
incorporation of an acidic material after the addition of an alkaline material
to reduce the pH of the composition without negatively impacting the viscosity
of the composition.
