Abstract: A solid, liquid, or gel formulation including: (A) alkali metal sulfite or alkali metal bisulfite, and (B) at least one graft copolymer formed from: at least one graft base selected from nonionic monosaccharides, disaccharides, oligosaccharides, and polysaccharides, and side chains obtainable by grafting of at least one ethylenically unsaturated mono- or dicarboxylic acid and at least one compound of the general formula (I), where the variables are each defined as follows:
R1 is chosen from methyl and hydrogen,
A1 is chosen from C2-C4-alkylene,
R2 are the same or different and chosen from C1-C4-alkyl,
X− is chosen from halide, mono-C1-C4-alkylsulfate and sulfate,
where alkali metal (bi)sulfite (A) and graft copolymer (B) are present in a weight ratio in the range from 1:100 to 10:1.
