摘要：
Spherical silica and/or silicate particles having a d50 median particle size from 1 to 5µm, a d95 particle size less than 8µm, an oil absorption from 40 to 100 cc/100g, a pack density from 20 to 60lb/ft3, and a sphericity factor (S80) of at least 0.9,are disclosed, as well as methods for making these spherical particles, and dentifrice compositions containing the spherical particles.
