## Abstract

Oral composition comprising a Camellia extract of semi-oxidized tissue from a member of the genus Camellia and an enhancing agent.

## Claims

### Claim at position 1

-14. (canceled)

### Claim 15

A method of using an oral composition for removing dental plaque and/or inhibiting deposition of dental plaque within an oral cavity, the oral composition comprising: a Camellia extract of semi-oxidized tissue; and an enhancing agent.

### Claim 16 (depends on 15)

A method according to claim 15, wherein the Camellia extract is an Oolong tea extract.

### Claim 17 (depends on 15)

A method according to claim 15, wherein the Camellia extract is an extract of Camellia leaves that have been oxidized about 20% to about 60%.

### Claim 18 (depends on 15)

A method according to claim 15, wherein the enhancing agent is a water soluble or swellable anionic polymer or co-polymer comprising delivery enhancing groups and retention enhancing groups, the delivery enhancing groups enhancing delivery of components of the Camellia extract to teeth and oral tissue, and the retention enhancing groups enhancing retention by the teeth and the oral tissue of components of the Camellia extract.

### Claim 19 (depends on 15)

A method according to claim 15, wherein the enhancing agent is a copolymer of maleic acid or anhydride with methylvinylether.

### Claim 20 (depends on 15)

A method according to claim 15, additionally comprising an antibacterial agent.

### Claim 21 (depends on 15)

A method according to claim 15, additionally comprising a solubilizing agent.

### Claim 22

A method for at least one of removing dental plaque and inhibiting deposition of dental plaque within an oral cavity of a human or other animal subject comprising topically contacting teeth of the subject with an oral composition containing: (A) a Camellia extract of semi-oxidized tissue; and (B) an enhancing agent.

### Claim 23 (depends on 22)

A method according to claim 22, wherein the Camellia extract is an extract of Camellia leaves that have been oxidized about 20% to about 60%.

### Claim 24 (depends on 22)

A method according to claim 22, wherein the enhancing agent is a copolymer of maleic acid or anhydride with another polymerizable ethylenically unsaturated monomer.

### Claim 25 (depends on 22)

A method according to claim 22, further comprising a solubilizing agent.

### Claim at position 13
