摘要：
Disclosed are oral care compositions comprising selected surface-activeorganophosphate compounds and methodsof use to provide protection of teeth from erosion caused by the action ofchemicals, such as harsh abrasives and acids. Thesurface-active organophosphate compounds are substantive to teeth, thephosphate groups binding the calcium in teeth and thuspreventing loss of calcium from dissolution when contacted with acids. Theorganophosphate compound may also deposit aprotective surface coating that prevents contact of teeth with erosivechallenges. Selected organophosphate compounds contain one ormore phosphate groups and are combined in the oral care composition with oneor more of a fluoride ion agent, an antimicrobialagent preferably selected from quaternary ammonium compounds and polyvalentmetal salts, an anticalculus agent and additionalsurfactant, to provide benefits including superior anti-erosion, anticaries,antiplaque and anti-staining as demonstrated byenhanced fluoride uptake, remineralization, resistance to aciddemineralization and antimicrobial activities, resulting in improvedoverall tooth health, structural integrity and appearance.
