摘要：
The invention relates to oral and dental hygiene and cleaning agents, including—with respect to the weight thereof—a) 0.001 to 5 wt % of copolymer(s) comprising at least one structural unit of formula (A1) and at least one structural unit of formula (A2)； b) formula (A1), formula (A2), wherein R1 stands for a (C1 to C18)-alkyl group, R2 stands for a (C1 to C6)-alkyl group, M stands for a hydrogen atom or an equivalent of a monovalent or polyvalent cation； and c) 0.1 to 10 wt % of pentasodium triphosphate； which result synergistically in improved cleaning power for surface stains on teeth and in improved prevention of reforming dental calculus, without abrasion of hard dental tissue being increased.
