The present invention relates to agents for oxidative hair lightening or bleaching with a pH in the range from 10.0 to 11.0, preferably in the range from 10.1 to 10.8, containing 70-95% by weight of water, alkalizing agents , 0.1-2 wt .-% anionic, zwitterionic or amphoteric surfactant, 0.1-1.5 wt .-% sodium polyacrylate, with only small amounts, if at all, of linear saturated alkanols with two or three hydroxyl groups and 2 to 8 carbon atoms in the alkyl group, furthermore no saturated and unsaturated non-alkoxylated alkanols with a hydroxyl group and 1 to 50 carbon atoms in the alk (en) yl group, no saturated and unsaturated alkanecarboxylic acids with 1 to 50 carbon atoms, no crosslinked copolymer, built up from acrylic acid and non-ethoxylated esters of acrylic acid with linear C10-C30 monoalcohols as monomers and no oxidizing agents are included. |
