Abstract
Abstract These dyeing compositions containing precursors of oxidizing dyestuffs, alkalinizing agents and a weak oxidizing agent added before using the compositions, contain as an alkalinizing agent the carbonate of an amino acid alkali metal or ammonium salt, as an at least partial substitute for ammonia previously used as an alkalinizing agent, possibly in conjunction with organic bases, said carbonate being neither volatile nor aggressive and making it possible to obtain dyeing compositions free of unpleasant odors and free of any aggressiveness for the scalp while yielding particularly attractive and aesthetic shades.
