## Abstract

The present document describes an oral care composition comprising a cuttlefish bone powder, comprising particles having more than 95% (w/w) calcium carbonate content, and a particle size of from about 60 microns to about 75 microns, and a suitable carrier, and uses of said composition for oral hygiene.

## Claims

### Claim at position 1

1-70. (canceled)

### Claim 71

A method of teeth whitening, the method comprising applying to at least one tooth in need of whitening an oral care composition, comprising:
(a) a cuttlefish bone powder having particles with at least 95% (w/w) calcium carbonate content and a particle size from 60 microns to 61 microns; and
(b) a suitable carrier.

### Claim 72 (depends on 71)

The method of claim 71, wherein the at least one tooth is in an oral cavity.

### Claim 73 (depends on 71)

The method of claim 71, wherein the calcium carbonate content is from about 95% (w/w) to about 99.9% (w/w).

### Claim 74 (depends on 71)

The method of claim 71, wherein the cuttlefish bone powder has a relative density of about 0.15 to about 1.30.

### Claim 75 (depends on 71)

The method of claim 71, wherein the cuttlefish bone powder has a porosity of about 0.25 to about 0.45.

### Claim 76 (depends on 71)

The method of claim 71, wherein the cuttlefish bone powder has a suspension time in water of about 5 h to about 8 h.

### Claim 77 (depends on 71)

The method of claim 71, wherein the composition contains from about 0.1% (w/w) to about 20% (w/w) of the cuttlefish bone powder.

### Claim 78 (depends on 71)

The method of claim 71, further comprising:
(a) an abrasive;
(b) a thickening agent;
(c) a humectant;
(d) an emulsifier;
(e) a surfactant;
(f) a pH regulator;
(g) a solvent;
(h) an antimicrobial agent; and/or
(i) a preservative.

### Claim 79 (depends on 78)
