Abstract

A stomatic composition has particles of hydroxyapatite with an average particle size in length (l), width (d) and thickness (h) of: l from 0.2 μm to about 0.01 μm, d from about 0.1 μm to about 0.001 μm and h from about 0.1 μm to about 0.001 μm.

Claims (14)

1. A stomatic composition characterised in that it comprises particles of hydroxyapatite with an average particle size in length (l), width (d) and thickness (h) of: (1) from about 0.2 μm to about 0.01 μm, (d) from about 0.1 μm to about 0.001 μm, and (h) from about 0.1 μm to about 0.0001 μm with the particles of hydroxyapatite having a specific surface of hydroxyapatite from 100 m 2 /g to 150 m 2 /g.

2. The stomatic composition according to claim 1 characterised in that it comprises particles of hydroxyapatite with an average particle size in length (l), width (d) and thickness (h) of about (1)=0.06 μm +/−50%, (d)=0.015 μm +/−50% and (h)=0.005 μm +/−50%.

3. The stomatic composition according to claim 1 characterised in that it comprises particles of hydroxyapatite with an average particle size in length (l), width (d) and thickness (h) of about (l)=0.06 μm, (d)=0.015 μm, (h)=0.005 μm.

4. The composition according to claim 1 characterised in that the hydroxyapatite particles are present in the composition in an amount of 0.1% to 50% by weight, based on the weight of the stomatic composition.

5. The composition according to claim 1 characterised in that the hydroxyapatite is a synthetic hydroxyapatite which contains 99.9% of Ca 10 (PO 4 ) 6 (OH) 2 by weight.

6. The composition according to claim 1 further comprising at least one substance selected from the group consisting of

humectants in a range from about 0% to 85% by weight,

binders and thickeners in a range of 0% to 10% by weight,

abrasive materials in a range from 0.0% to 25%,

surfactants in a range from 0% to 5% by weight,

flavours in a range from 0% to 5% by weight, based on the weight of the composition.

7. The composition according to claim 1 further comprising gingivitis treating agents comprising extracts of natural plants selected from the group consisting of urtica, millefolium, chamomilla hypericum, salvia, and in an aqueous or an aqueous-alcoholic form.

8. The composition according to claim 1 further comprising effective amounts of anti-microbial and anti-plaque agents.

9. A stomatic composition comprising particles of hydroxyapatite with an average particle size in length (l), width (d) and thickness (h) of: (l) from about 0.2 μm to about 0.01 μm, (d) from about 0.1 μm to about 0.001 μm, and (h) from about 0.1 μm to about 0.0001 μm, and effective amounts of gingivitis treating agents comprising extracts of natural plants selected from the group consisting of urtica, millefolium, chamomilla hypericum, and salvia, in an aqueous or an aqueous-alcoholic form.
