Two-part aqueous composition for coloring hair, which forms a gel on mixing of the two parts

A kit containing a two part aqueous composition which forms a gel on mixing of the two parts for coloring human hair comprising separate first and second containers:

• a:
• the first container containing an alkaline aqueous lotion having a pH of from about 7 to about 11 containing from about 0.005% by weight to about 5% by weight of at least one primary intermediate and at least one coupler for the formation of oxidation dyes, from about 0.1% to about 5% by weight of a monomeric quaternary ammonium compound of the formula ##STR6## wherein R.sub.1, R.sub.2 and R.sub.3, which may be the same or different, represent benzyl or lower alkyl groups containing 1 to 6 carbon atoms, R.sub.4 represents a long chain alkyl group containing from about 12 to about 22 carbon atoms and X is an anion from about 0.5 to about 15% by weight of an amphoteric surfactant and at least 70% by weight water;
• b:
• the second container containing an aqueous developer having a pH of from about 2 to about 6 containing from about 0.5% by weight to about 40% by weight of a peroxide oxidizer and from about 0.1% by weight to about 20% by weight of a water insoluble anionic polymer which dissolves to form said gel when mixed with said alkaline aqueous lotion.

A method of coloring human hair which comprises contacting the hair with a mixture of a two part aqueous composition which forms a gel on mixing of the two parts comprising:

• a:
• an alkaline aqueous lotion having a pH of from about 7 to about 11 containing from about 0.005% by weight to about 5% by weight of at least one primary intermediate and at least one coupler for the formation of oxidation dyes, from about 0.1% to about 5% of a monomeric quaternary ammonium compound of the formula ##STR7## wherein R.sub.1, R.sub.2 and R.sub.3, which may be the same or different, represent benzyl or lower alkyl groups containing 1 to 6 carbon atoms, R.sub.4 represents a long chain alkyl group containing from about 12 to about 22 carbon atoms and X is an anion, from about 0.5% to about 15% by weight of an amphoteric surfactant and at least 70% by weight water;
• b:
• an aqueous developer having a pH of from about 2 to about 6 containing from about 0.5% by weight to about 40% by weight of a peroxide oxidizer and from about 0.1% by weight to about 20% by weight of a water insoluble anionic polymer which dissolves to form said gel when mixed with said alkaline aqueous lotion, and maintaining such contact until the hair is permanently colored.
