Abstract
The invention relates to substantially dust free bleach powders that, when mixed with aqueous hydrogen peroxide, yield activated bleach compositions that exhibit improved thixotropy. The bleach powders comprise at least one de-dusting agent and at least one peroxygenated salt. The de-dusting agents, which are preferably present in an amount less than about 10% by weight of the bleach powder are inert, substantially hydrophilic compounds selected from alkylated esters, cyclic ethers and cyclic esters. Optionally, one or more hair conditioning agents, thickeners and desiccants may be added to the dust free bleach powder.
