Abstract
The instant disclosure relates to hair coloring base compositions and developer compositions that can be incorporated into a hair color cartridge, which combines the compositions and dispenses them onto hair. The hair color cartridge includes: (a) one or more hair coloring base compositions and; (b) one or more developer compositions, which can be combined to form an active hair coloring composition and dispensed onto hair. The hair coloring base compositions typically include one or more oxidative dye precursors; one or more alkalizing agents; one or more reducing agents; optionally, one or more cationic conditioning polymers; one or more surfactants; one or more water-soluble solvents; and water. The developer compositions typically include one or more oxidizing agents; one or more surfactants; and water. The unique components and fluid characteristics of the various compositions are such that devices or appliances comprising them accurately combine and dispense the hair coloring base composition(s) with the developer composition(s) in a predetermined ratio with excellent consistency for application to hair.
