This invention relates to compounds and their use in oral hygiene compositions as anti-stain, anti-calculus, anti-bacterial, and anti-malodor agents. These agents are characterized by having two basic building blocks, one with the ability to strongly bind to the tooth surface by containing a functional group that allows the molecule to adsorb to the surface of teeth, the other by having a number of chemical moieties that are capable of binding strongly to water, preferably, to at least two water molecules.

L'invention concerne des composés et l'utilisation de ces composés dans des compositions destinées à l'hygiène bucco-dentaire, en tant qu'agents antidépôts, antitartre, antibactériens et anti-mauvaise haleine. Ces agents se caractérisent par deux motifs structuraux de base, dont l'un est capable de se lier solidement avec la surface dentaire grâce à un groupe fonctionnel qui permet l'adsorption de la molécule, sur la surface dentaire, et l'autre comprend plusieurs groupes chimiques caractéristiques capables de se lier solidement avec l'eau, de préférence avec au moins deux molécules d'eau.
