Abstract

A SILICA USABLE IN DENTIFRICE COMPOSITIONS HAS A COMPATIBILITY WITH CHLORHEXIDINE AND OTHER PRODUCTS OF THE GUANIDINE TYPE OF AT LEAST 65%, PREFERABLY AT LEAST 90% IT ALSO HAS AN ACIDITY HO OF AT LEAST 3.3. IT IS PREPARED BY REACTING A SILICATE WITH AN ACID TO OBTAIN A SILICA GEL OR SUSPENSION, SEPARATING THE SILICA, WASHING THE CAKE RESULTING THE SEPARATION WITH WATER UNTIL THE CONDUCTIVITY OF THE FILTRATE IS AT MOST 200 MICROSIEMENS.CM-1, AND DRYING THE SILICA CAKE, OR BY REACTING A SILICATE WITH AN ACID TO OBTAIN A SILICA GEL OR A SUSPENSION, FOLLOWED BY THE SEPARATION OF THE SILICA, WASHING THE RESULTING CAKE WITH WATER AND THEN WASHING OR TREATING IT WITH AN ACID SOLUTION, AND THEN DRYING THE CAKE.
