DECOLORIZATION OF COLORED KERATINIC FIBERS
First Claim
1. A multi-component packaging unit (kit of parts) for the reductive decolorization of colored keratinic fibers comprising, packaged separately from one another,(I) a container (A) containing a cosmetic agent (a),(II) a container (B) containing a cosmetic agent (b), and(III) a container (C) containing a cosmetic, aqueous agent (c), withthe agent (a) in container (A) comprising(a1) one or more reducing agents selected from the group consisting of sodium dithionite, zinc dithionite, potassium dithionite, sodium sulfite, sodium hydrogen sulfite, potassium sulfite, potassium hydrogen sulfite, ammonium sulfite, sodium thiosulfate, potassium thiosulfate, ammonium thiosulfate, hydroxymethane sulfinic acid, aminomethane sulfinic acid, cysteine, thiolactic acid, sulfanylacetic acid (thioglycolic acid), ascorbic acid, and mixtures thereof, andagent (c) in container (C) comprising(c1) one or more acids from inorganic and/or organic acids and(c2) one or more zwitterionic and/or amphoteric surfactants.
