[0078] The compositions shown in Table 1 below can be used on pre-colored hair. Hair coloring solution mixed with 100 grams of 20 volumes of hydrogen peroxide. The resulting mixture is applied to the hair and left in contact with the hair for 30 minutes. The colored hair is then washed, rinsed with water and dried.

Abstract

Couplers for hair coloring compositions for oxidative dyeing of hair are compounds of the formula (1): wherein X is selected from halogen and R5SO4, R, R1, R2 and R5 are each individually selected from C1 to C22 alkyl and C1 to C22 mono or dihydroxyalkyl and R3 and R4 are each individually selected fro C1 to C6 alkyl groups, C1 to C6 hzdroxyalkyl, C1 to C6 alkoxy, C1 to C6 aminoalkyl or R3 and R4 together from a C1 to C5 alklene group.

Description

field of invention [0001] The present invention relates to novel couplers for use in hair coloring compositions comprising one or more oxidative hair coloring agents for use in combination with one or more oxidizing agents. The present invention also relates to hair coloring compositions of such novel couplers and to hair coloring using compositions containing such couplers. Background of the invention [0002] Hair coloring is a process derived from ancient practices using various methods. The most widely used hair coloring method in modern times is by an oxidative hair coloring method which utilizes a hair coloring system which combines one or more oxidative hair coloring agents with one or more oxidizing agents. [0003] Most commonly a peroxygen oxidizer is used in combination with one or more oxidative hair dyes, usually small molecules that diffuse into the hair and contain one or more primary intermediates and one or more couplers . In this process, a peroxide such...
