Aqueous oxidizing composition comprising amino acids

A cosmetic composition, comprising:

• an aqueous oxidizing composition B having a pH in the range of 1 to 6, and comprising, relative to the total weight of composition B:
• a) 3-12 wt % hydrogen peroxide, and
• b) 0.01-0.5 wt % in total of one or more selected from the group consisting of alanine, glycine, a salt thereof, and a mixture thereof;
• a bleaching powder composition A, comprising, relative to the total weight of composition A:
• c) 25-60 wt % in total of one or more persulfate salts selected from the group consisting of sodium persulfate, ammonium persulfate, and potassium sulfate,
• d) 5-15 wt % in total of one or more alkalizing agents selected from the group consisting of sodium metasilicate, sodium carbonate, potassium carbonate, and ammonium carbonate, and
• e) 1-5 wt % in total of one or more polycarboxylic acids selected from the group consisting of malic acid, oxalic acid, malonic acid, succinic acid, fumaric acid, adipic acid, maleic acid, glutaric acid, pyromelletic acid, and a salt thereof;
• and
• optionally one or more compositions selected from the group consisting of:
• an oxidative dyeing composition C having a pH in the range of 7 to 12 and comprising one or more oxidative dye precursors and/or oxidative dye couplers, and one or more alkalizing agents, and
• an aqueous permanent waving composition D having a pH in the range of 7 to 12 and comprising one or more reducing agents and one or more alkalizing agents,
• wherein the compositions C and D further comprise one or more polycarboxylic acids, or a salt thereof, selected from the group consisting of malic acid, oxalic acid, malonic acid, succinic acid, fumaric acid, adipic acid, maleic acid, glutaric acid, pyromelletic acid, a salt thereof, and a mixture thereof, and
• a weight ratio of the bleaching powder composition A to the aqueous oxidizing composition B is in a range of from 5:1 to 1:5.
