[PROBLEMS] To provide a composition for cleaning keratin substances, including nanoparticles of aluminum oxide. SOLUTION: The present invention relates to a cosmetically acceptable aqueous medium comprising particles consisting essentially of aluminum oxide and having an average primary particle size of less than 200 nm, at least one anionic surfactant and at least one The present invention relates to a cleaning composition for cleaning keratin substances, which comprises an amphoteric or nonionic surfactant. The invention also relates to a method for the cosmetic treatment of keratin fibers and to the use of the composition according to the invention as a shampoo. The numerical value of the primary particle size of the particles of the present invention is preferably 5 to 50 nm. The aluminum oxide may be hydrated alumina. In the composition according to the invention, the particles of aluminum oxide are present in an amount of from 0.01 to 20% by weight, preferably from 0.1 to 5% by weight, based on the total weight of the cleaning composition of the invention. It can be used in amounts in the range of% by weight. |
