Claim 2
Dependent Claim
80 words
FINELY DIVIDED VISIBLE FUNCTIONAL PARTICLES, WHICH ALLEVIATE PERIODONTAL SENSITIVITY AND BLEEDING UPON APPLICATION TO TEETH AND GUMS HAVING A MACROSCOPE SIZE OF 100 TO 1000 MICRONS, COMPRISING A MATRIX OF MELTABLE BINDING MATERIAL SELECTED FROM THE GROUP CONSISTING OF C12 TO C22 SATURATED FATTY ACID DI- OR TRI-ESTER OF GLYCEROL OR ETHYLENE GLYCOL AND ABOUT 5-10% BY WEIGHT OF ALUMINUM DIHYDROXY ALLANTIONATE SAID MELTABLE BINDING MATERIAL HAVING A MELTING OR SOFTENING POINT LOWER THAN THE DECOMPOSITION POINT OF SAID ALLANTIONATE.
Claim 3
Dependent Claim
80 words
Finely divided visible functional particles, which alleviate periodontal sensitivitity and bleeding upon application to teeth and gums having a macroscopic size of 100 to 1000 microns, comprising a matrix of meltable binding material selected from the group consisting of C12 to C22 saturated fatty acid di- or tri-ester of glycerol or ethylene glycol and about 5-10% by weight of aluminum chlorohydroxy allantoinate, said meltable binding material having a melting or softening point lower than the decomposition point of said allantoinate.
Claim 4
Dependent Claim
80 words
Finely divided visible functional particles, which alleviate periodontal sensitivitity and bleeding upon application to teeth and gums having a macroscopic size of 100 to 1000 microns, comprising a matrix of meltable binding material selected from the group consisting of C12 to C22 saturated fatty acid di- or tri-ester of glycerol or ethylene glycol and about 5-10% by weight of aluminum chlorohydroxy allantoinate, said meltable binding material having a melting or softening point lower than the decomposition point of said allantoinate.
