FINE SUSPENSIONS OF POORLY SOLUBLE CALCIUM SALTS AND THEIR USE IN DENTAL CARE PRODUCTS

摘要

The invention relates to suspensions of poorly water-soluble calcium salts, selected from the phosphates, fluorides and fluorophosphates, in liquid medi a, preferably in water, containing suspended primary particles between 5 and 50 nm in diameter and between 10 and 150 nm in length. Said suspensions are stabilized by a contents of at least 0.01 % by weight, in relation to the weight of the suspension, of a water-soluble surface-active agent or water- soluble polymeric protective colloid so as to prevent agglomeration. The suspensions are suitable as remineralizing components in compositions used f or the cleaning and care of the teeth.
