COMPOSITION FOR THE OXIDATION DYEING OF KERATIN FIBRES COMPRISING A NONIONIC DERIVATIVE OF CELLULOSE WITH HYDROPHOBIC SUBSTITUENT(S), AN OXIDATION BASE OF DIAMINODIAZACYCLOPENTENE TYPE AND AN OXIDATION COUPLER, OXIDATION DYEING PROCESS AND USE.

摘要

Composition for coloring keratin fibers, comprises one or more non-ionic cellulose derivatives comprising one or more hydrophobic substituents comprising 8-30C, one or more oxidation bases comprising diaminodiazacyclopentene derivatives and their addition salts, and one or more oxidation couplers, in a medium. Independent claims are included for: (1) a process for oxidation coloring of keratin fibers, comprising applying a coloring composition on the fibers in the presence of at least an oxidizing agent for a sufficient time to develop the desired color; and (2) a device with several compartments comprising at least a first compartment containing a coloring composition and at least a second compartment containing an oxidizing agent.
