ANTIBACTERIAL AND BLEACHING ORAL AND DENTAL HYGIENE AND CLEANING AGENT II

摘要

The invention relates to preparations for oral and dental hygiene and cleaning, in particular bleaching agents for teeth, which effectively fight mouth odor and are effective against gingivitis and periodontitis without large amounts of peroxide being necessary, comprising in a matrix suitable for oral application - 0.01 to 20 wt % of at least one cationic acylpyridinium derivative according to the following formula (I), where R1 is a C1-C6 alkyl group, a C2-C6 alkenyl group, a C2-C6 hydroxyalkyl group, a C1-C6-alkoxy-C2-C6-alkyl group, a carboxy-C2-C6-alkyl group, an aryl-C1-C6-alkyl group, a heteroaryl-C1-C6-alkyl group, an aryl group or a heteroaryl group, R2 is an acyl group R'C(O), in which R' is a C1-C6 alkyl group, a C2-C6-hydroxyalkyl group, a C1-C6-alkoxy-C2-C6-alkyl group, a carboxy-C1-C6-alkyl group, an aryl-C1-C6-alkyl group or a heteroaryl-C1-C6-alkyl group, R3, R4 and R5 can be, independently of each other, a hydrogen atom, a hydroxy group, an amino group, a Di-(C1-C6-alkyl)-amino group, a C1-C6-alkyl group, a C1-C6-alkoxy group, a C1-C6-alkoxy-C2-C6-alkyl group, a halogen, a nitro group, a carboxy group, a nitrile group, an aryl group which is substituted when necessary, a C2-C6-alkenyl group, a heteroaryl group which is substituted when necessary, and the anion X is a physiologically compatible anion; - 0.3 to 30 wt % of a bleach component selected from hydrogen peroxide and/or the addition compounds thereof to solid carriers and/or carbamide peroxide and/or peroxo compounds.
