摘要：
A storage stable, re-usable hair coloring composition comprising: (a) an oxidizing agent; and (b) an oxidative hair coloring agent; wherein the pH of each of (a) and (b) is in the range of from about 1 to about 6 and wherein the combined mixture of (a) and (b) has a pH in the range of from about 1 to about 5 and wherein both (a) and (b) are capable of being stored at low pH, either separately, or, once mixed, for at least 1 month at room temperature and wherein the resultant color delivered to the hair (Delta E) is up to about 75%, preferably up to about 85%, more preferably up to about 90% and most preferably up to about 95% of the total color delivered to the hair (Delta E) from a mixture of (a) and (b) on mixing. The products are storage stable and re-usable and can provide excellent hair coloring and in-use efficacy benefits in combination with improved color retention potential after storage at room temperature.
