Abstract: The invention relates to a process for producing surface postcrosslinked water-absorbing polymer particles, wherein the water-absorbing polymer particles are coated, before, during or after the surface postcrosslinking, with at least one basic salt of a trivalent metal cation and a monovalent carboxylic acid anion, wherein the basic salt is applied in the form of a solution that is stabilized by a vicinal diol and/or an amide of the formula R1—CO—NR2R3 where R1 is not H and in which R1 is not H2N— if both R2 and R3 are H. Further, the invention relates to solutions of at least one basic salt that are stabilized by a vicinal diol and/or an amide of the formula R1—CO—NR2R3 where R1 is not H and in which R1 is not H2N— if both R2 and R3 are H.
