Water in oil microemulsion peroxide compositions for use in oxidative dyeing of hair and related methods

摘要

A water in oil microemulsion peroxide composition for coloring or lightening of hair comprising 1-99% of an aqueous phase in the form of dispersed microdroplets having a droplet size of 100 to 1500 Angstroms, 0.1-75% of a continuous oil phase; and 1-65% of an organic, surface active ingredient capable of interacting with the water phase and the oil phase to cause formation of the dispersed aqueous phase microdroplets, all percentages by weight of the total composition; and a method for coloring or lightening hair using the peroxide composition, and a method for reducing the amount of time necessary to permanently color hair using the peroxide composition.
