Copolymers of polyamino acids as tartar barrier agents |
| 摘要 |
Copolymers of polyamino acids formed by reaction of polysuccinimide with alkyl, alkenyl, aromatic amines or alkyl and alkenyl polyamines are useful as inhibitors of tartar deposition. Such compounds may be used in conventional dentrifice compositions to prevent tartar deposition on natural or false teeth.
