| titleOfInvention | Process for preparing precipitated silica composition and product thereof |
| abstract | FIELD OF THE INVENTION The present invention relates to a process for preparing abrasive compositions, and more particularly, to a process for preparing precipitated silica abrasive compositions having good cleaning performance and lower wear, wherein the post-reactor sizing treatment of abrasive particles is wet milling. And directly by centrifugation followed by hydraulic chamber press filtration, optionally in combination with vacuum dewatering and deagglomeration. It was determined that higher pellicle membrane cleaning levels could be achieved without increasing the dentin wear properties of the silica product itself, targeting specific particle size ranges. As a result, dentifrices comprising abrasive silica products classified as above exhibit particularly desirable cleaning effects, which can provide improved tooth improved tooth gloss, whitening and the like without adversely affecting hard tooth surfaces. The invention also relates to dentifrices comprising products of such selective process configurations and specially prepared and classified silica products. |
