ORAL AND DENTAL HYGIENE AND CLEANING AGENTS FOR REDUCING TOOTH DISCOLORATION

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.
