Abstract
The present invention relates to an aqueous composition for bleaching keratin fibers, and in particular human keratin fibers such as the hair, having a viscosity of less than 2×10poises and comprising, in a cosmetically acceptable medium, hydrogen peroxide and at least 20% by volume of suitably selected inert particles, to a bleaching process using this composition, and also to the use of this composition for bleaching keratin fibers. The composition in accordance with the invention makes it possible rapidly to obtain substantial lightening of keratin fibers, while at the same time limiting the degradation of the keratin fibers and the skin irritation.
