CALCIUM CARBONATE COMPOSITIONS FOR USE IN THE MANUFACTURE OF TOOTHPASTE

摘要

An aqueous suspension of particulate calcium carbonate for use in the manufacture of toothpaste compositions includes in addition to the calcium carbonate one or more dispersing agents and one or more preservative agents and wherein the aqueous medium of the suspension has been treated so that the biological contamination of the suspension is not greater than the maximum allowable levels indicated by the US Food and Drugs Administration (FDA). The calcium carbonate may comprise a precipitated and/or ground calcium carbonate. The suspension may have a solids content of from 50 % to 99.5 % by weight. The suspension may be flowable and pumpable.
