Abstract (en)

[origin: WO2011065934A1] Powder hair coloring or bleaching composition comprising: a) at least one solid source of carbonate ions, carbamate ions, hydrogencarbonate ions, or mixtures thereof; b) at least one solid source of oxidizing agent; c) at least one solid source of ammonium ions; and d) a crosslinked carboxylic acid polymer thickener having a particle size of no more than about 10 microns in an amount which, upon admixture of the powder composition with water to provide a concentration of from about 1% to about 3%, provides the dispersed composition a viscosity of from about 10000mPas to about 20000mPas when measured at 0.5rpm using Brookfield viscometer spindle S52, and a pH of from about 8.5 to about 9.4.
