Abstract
Abstract Tartrate monosuccinate and tartrate disuccinate compounds of the formulae HO(CHCOOX)CH(COOX)OCH(COOX)CH2COOX and CH2(COOX)CH(COOX)O(CH[COOX])2OCH(COOX)CH2COOX are used in combination with various polymers to provide anticalculus and antiplaque effects on teeth. Oral care compositions such as dentifrices, mouthwashes, and the like, are provided. Use of the tartate-succinates and polymers in combination with other oral car ingredients such as fluoride, pyrophosphate and antibacterials is also described.

Claim 2
Dependent Claim
51 words
An oral care composition, comprising: a) an effective amount of an anticalculus agent which is a member selected from the group consisting of the acid or salt form of tartrate monosuccinate, tartrate disuccinate, and mixtures thereof; b) an effective amount of a plaque-inhibiting polymer; and c) a toxicologically acceptable oral carrier.
Claim 3
Dependent Claim
19 words
An oral care composition according to claim 1 comprising at least about 0.1% by weight of said anticalculus agent.
Claim 4
Dependent Claim
