Abstract (en)
[origin: WO9905245A1] The invention relates to the use of electrolyte mixtures containing a) lignin sulfonates and b) at least one other electrolyte salt from the group made up of polyacrylates, phosphonates, silicates, carbonates and citrates as sequestering agents for producing aqueous bleaching agents. According to the invention, preparations which reliably prevent fabric from yellowing, preferably chlorine bleaching solutions, can be obtained especially together with chlorine-resistant tensides.
