Patent

CA 2222407

The present invention is directed to oral care ULTRAMULSIONTM based oral care products, including, toothpastes, treated flosses and dental stimulators, interdental coating substances, oral rinses, mouth/throat conditioning internal treatment products, and anti-gingivitis products. All of these products are improved when an ULTRAMULSIONTM dispersion containing silicone and a surfactant is used as taught herein. The ULTRAMULSIONTM dispersions of the present invention combine certain characteristics of emulsions with certain features of microemulsions. Like conventional emulsions, they are two phase systems comprising a silicone dispersed in a continuous, surfactant phase, wherein the silicone is insoluble in the surfactant. Unlike conventional emulsions, but like microemulsions, these dispersions are stable. Unlike microemulsions, but like conventional emulsions, mechanical work is required to form ULTRAMULSIONTM dispersions. Unlike microemulsions, but like conventional emulsions, these ULTRAMULSIONTM dispersions are not formed spontaneously. Like conventional emulsions, the ULTRAMULSIONTM dispersions do not contain a cosolvent commonly found in microemulsions.

L'invention porte sur différents produits pour soins de la bouche à base d'ULTRAMULSION?TM¿ dont des dentifrices, du fil dentaire traité, des stimulateurs dentaires, des substances pour revêtements interdentaires, des bains de bouche, des produits de traitement interne de la bouche ou de la gorge, et des produits anti-gingivite. Tous ces produits peuvent être améliorés par adjonction d'une dispersion d'ULTRAMULSION?TM¿ contenant une silicone et un tensio-actif. De telles dispersions combinent certaines caractéristiques des émulsions et certaines caractéristiques des micro-émulsions. Comme les émulsions classiques, ces dispersions sont des systèmes à deux phases, c.-à-d. une silicone dispersée dans une phase continue de tensio-actif dans laquelle la silicone est insoluble, mais, contrairement aux émulsions classiques, elles présentent la stabilité des micro-émulsions. Contrairement aux micro-émulsions, mais, comme les émulsions classiques, leur formation demande un travail mécanique. Contrairement aux micro-émulsions, mais, comme les émulsions usuelles, ces dispersions ne se forment pas spontanément. Comme les émulsions classiques, ces dispersions ne contiennent pas de cosolvant, ce qui est par contre souvent le cas des micro-émulsions.
