Patent

CA 2571327

Oral care compositions are described herein. The oral care compositions generally have rheological properties that are desirable for use in a dispensing toothbrush. In some instances, the oral care composition has a yield point of y Pa and a shear slope of x Pa/Sec, wherein the ratio of yield point to shear slope is less than y/(74 - 370x + 470x2). In some instances, the oral care composition has a Newtonian viscosity at 400 Pa of less than 1.0Pa.s.

La présente invention a trait à des compositions de soins buccaux. D'une manière générale, les compositions de soins buccaux présentent des propriétés rhéologiques qui sont souhaitables pour être utilisées dans une brosse à dents de distribution. Dans certains modes de réalisation, la composition de soins buccaux présente une limite apparente d'élasticité de y Pa et une pente en cisaillement de x Pa/sec, le rapport de limite apparente d'élasticité à la pente en cisaillement étant inférieur à y/(74 - 370x + 470x2). Dans certains modes de réalisation, la composition de soins buccaux présente une viscosité newtonienne à 400 Pa inférieure à 1,0 Pa.
