Agents for oxidative hair lightening or bleaching are disclosed with a pH value in the range from about 10.0 to about 11.0, preferably in the range from about 10.1 to about 10.8, containing from about 70 - 95% by weight of water, alkalizing agent, from about 0.1 - 2% by weight of anionic, zwitterionic or amphoteric surfactant, from about 0.1 - 1.5% by weight of sodium polyacrylate, wherein only small amounts, if any, of linear saturated alkanols having two or three hydroxy groups and from 2 to 8 carbon atoms in the alkyl group. Further, none of the following are present - saturated and unsaturated non-alkoxylated alkanols having one hydroxy group and from 1 to 50 carbon atoms in the alk(en)yl group, saturated and unsaturated alkanecarboxylic acids with 1 to 50 carbon atoms, crosslinked copolymer built up from acrylic acid and non-ethoxylated esters of acrylic acid with linear C10-C30 monoalcohols as monomers and oxidizing agents. |
