Abstract
A storage stable dye composition having a pH of from 9 to 11, the dye composition comprising: (a) oxidation dye precursor, (b) at least 8 wt % of carbonate salt, (c) at least 2 wt. % of a fatty phase comprising fatty alcohol and quaternary conditioning agent, (d) hydroxypropyl starch phosphate, and (e) carrier, wherein the quaternary conditioning agent is present in the dye composition in an amount of at least 0.5 wt. %, and wherein the ratio of fatty alcohol to quaternary conditioning agent is 4:1 to 0.5:1. Hair coloring compositions formed from such dye compositions, as well as methods of coloring hair using such hair coloring compositions, are also disclosed.
