Total Claims: 10
Claim 1
Independent Claim
145 words
An opaque, transparent of translucent toothpaste dentifrice preparation comprising a toothpaste dentifrice base containing about 10-75% by weight of the preparation of a dentally acceptable water-insoluble polishing agent and about 0.15-50% by weight of the preparation of finely divided visible functional particles, which alleviate periodontal sensitivity and bleeding upon application to teeth and gums, having macroscopic size of 100 to 1000 microns, comprising a matrix of meltable binding material which binding material is a C 12 -C 22 saturated fatty acid di- or tri-ester of glycercol or ethylene glycol and about 5-10% by weight of anit-irritant compound selected from the group consisting of allantoin, aluminum dihydroxy allantoinate and aluminum chlorohydroxy allantoinate, said meltable binding material having a melting or softening point lower than the decomposition point of said anit-irritant compound, the total amount of said anti-irritant compound being about 0.1-5% by weight of the preparation.
Claim 2
Dependent Claim
