Claims13
An oral cleansing product comprising as an abrasive in a formulation of the oral cleansing product an alumina in the form of particles having d10 below 3.5 μm, d50 below 1.0 μm, and a specific surface area below 6 m2/g, wherein the alumina is at least 90% α-alumina calcined at a temperature of at least 900° C.
An oral cleansing method comprising cleaning parts of an oral cavity with an oral cleansing product containing alumina as an abrasive, wherein the alumina is in the form of particles having d10 below 3.5 μm, d50 below 1.0 μm, and a specific surface area below 6 m2/g, and wherein the alumina is at least 90% α-alumina calcined at a temperature of at least 900° C., such that he oral cleansing product is effective in removing deposits from dental surfaces without undesired removal of dental surface components.
An oral cleansing method comprising cleaning parts of an oral cavity with an oral cleansing product containing alumina as a whitening agent, wherein the alumina is in the form of particles having d10 below 3.5 μm, d50 below 1.0 μm, and a specific surface area below 6 m2/g, and wherein the alumina is at least 90% α-alumina calcined at a temperature of at least 900° C., such that the oral cleansing product is effective in removing deposits from dental surfaces without undesired removal of dental surface components.
