  • POWDER HAIR DYE COMPOSITION, USE THEREOF AND STORAGE PACKAGE THEREFOR
    Publication number: 20110203604
    Abstract: A powder hair dye composition containing sodium percarbonate with an active oxygen amount within a range of 12.0 to 15.3% by mass as a component (A), additionally containing a sequestering agent as a component (B) preferably and still additionally the sulfate salt of an oxidation dye as a component (C) more preferably. In accordance with the invention, the dyeability and bleaching ability of the powder hair dye composition can be enhanced, together with the resulting good hair feeling after application; additionally, the increase of oxygen gas pressure in the storage package can be suppressed, and the storage stability of the powder hair dye composition can be retained in a secure fashion.
