| titleOfInvention | Dentifrice compositions |
| abstract | Oral compositions, such as oral gels and toothpastes, containing a novel abrasive. An amorphous silica abrasive composition, comprising: a) a precipitated silica, comprising particles wherein said particles have: i) a mean particle size of from 5 to 11 microns (s.d. < 9); ii) an Einlehner hardness of from 0.8 to 2.5 for abrasive to brass screen and from 5 to 8 for abrasive to polyester screen; iii) an oil absorption of from 95 ml/100 gm to 135 ml/100 gm; and iv) a radioactive dentin abrasion of from 25 to 90; and b) a gel silica, comprising particles wherein said particles have: i) a mean particle size of from 5 to 11 microns (s.d. < 9); ii) an Einlehner hardness of from 3 to 15 for abrasive to brass screen and from 8 to 20 for abrasive to polyester screen; iii) an oil absorption of from 60 ml/100 gm to 130 ml/100 gm; and iv) a radioactive dentin abrasion of from 80 to 200 wherein at least 70 % of all of said particles have a diameter of below 25 microns and wherein the pellicle cleaning ratio is from 90 to 135, preferably from 110 to 135, and the radioactive dentin abrasion is from 60 to 100, preferably from 65 to 85, with a pellicle cleaning ratio/radioactive dentin abrasion ratio of from 1.20 to 1.60, preferably 1.25 to 1.50, and wherein the ratio of precipitated silica to gel silica is from 90:10 to 60:40, preferably 80:20 to 60:40, respectively. |
