Dental hygiene wipes comprising microcapsules

Abstract

The invention relates to a dental cleaning wipe comprising a non-woven textile support impregnated with a dental hygiene composition containing mechanically-broken microcapsules, the content of which is released by breaking the wall, as well as controlled-release microcapsules, the content of which is released by permeation through the wall, the walls of said microcapsules being water-insoluble.

Claims

1. Dental cleaning wipe consisting of a non-woven textile support impregnated with a dental hygiene composition in which at least some of the constituents are encapsulated in microcapsules deposited on the surface of the said non-woven textile support being characterized in that it includes two different types of microcapsules: mechanically broken microcapsules, the contents of which are released by breaking of the wall; and Diffusion-controlled microcapsules whose contents are released by permeation through the wall, and in that the wall of these microcapsules is insoluble in water.

2. Dental cleaning wipe according to claim 1, characterized in that said wipe comes in the form of a glove finger.

3. Dental cleaning wipe according to one of the claim 1 or 2, characterized in that the non-woven textile support is chosen from cellulose, chemically modified cellulose and cellulose-derived absorbent materials.

4. Dental cleaning wipe according to claim 1, characterized in that the thickness of the non-woven textile support is between 20 and 1500 μm, and is at least 2 times the average diameter of the microcapsules deposited on its surface.

5. Dental cleaning wipe according to claim 1, characterized in that the average diameter of the microcapsules deposited on its surface is between 1 and 50 μm.

6. Dental cleaning wipe according to claim 1, characterized in that the amount of microcapsules deposited on the non-woven textile support is 5 to 50 g/m2 of surface of the non-woven textile support.
