TH6040A - Toothpaste with alumina - hydrated. - Google Patents

Abstract

The invention is about toothpastes containing abrasives, alumina hydrates and fluoride-producing origin agents. According to this invention There is a toothpaste that contains ingredients that Give fluoride ions And precipitated alumina trihydrate, not crushed Is an abrasive, in which the alumina trihydrate particles are sized The average particle size is at least 3 μm.The average particle size of alumina trihydrate should be below 30 μm, the more preferred is from 5 to 20 μm, and the best used is 8 to The use of unmilled alumina trihydrate, obtained by flocculation, was found to reduce the useful fluoride loss in Retention While using the crushed alumina trihydrate to Cause significant loss of beneficial fluoride.
