COMPOSIÇÃO DE CUIDADO ORAL ESPUMÁVEL DE BAIXA DENSIDADE E COMPOSIÇÃO DE FLUORETO DENTAL ESPUMÁVEL DE BAIXA DENSIDADE

摘要

A dental fluoride foam composition comprising an aqueous solution of a water soluble fluoride ion releasable salt, a surfactant selected from the group consisting of nonionic surfactants, zwitterionic surfactants, betaine surfactants and mixtures thereof; and an orally compatible acidifying agent in an amount sufficient to adjust the pH of the composition to about 3 to about 5. The composition is stable at low temperatures and is a clear solution substantially free of precipitates when held at 4.4° C. for 12 hours. When dispensed from a container into the trough of a dental tray, the composition forms a low density, rapidly collapsible foam which substantially liquefies in about 1 minute after being dispensed from the foam generating container and placed in contact with a patient's teeth.
