Method of controlling perspiration

1. A product comprising a composition and a dispenser therefor, the composition being a gel, cream or soft solid of viscosity from 3000 mPa·s to 5200 mPa·s at a shear rate of 16/s comprising a non-pore blocking inhibitor of perspiration and the dispenser comprising a dome-shaped applicator surface of radius of curvature decreasing from a maximum of from 25 to 60 mm at its top/centre to a value of from 75 to 95% of its maximum value at, a distance of 1 cm from its top/centre.

2. A product according to claim 1 , wherein radius of curvature of the dome-shaped applicator surface decreases to a value of from 10 to 25% of its maximum at a distance between 1.5 cm and 2.5 cm from its top/centre.

3. A product according to claim 1 , wherein the diameter of the dome-shaped applicator surface is from 3 cm to 6 cm.

4. A product according to claim 1 , comprising an aperture in the applicator surface for release of the composition from an internally contained reservoir.

5. A product according to claim 4 comprising an over-cap for the applicator surface that serves to reduce evaporative loss from the composition through the aperture in the applicator surface.

6. A product according to claim 4 , comprising a drive mechanism for forcing the composition from its reservoir onto the applicator surface, said drive mechanism comprising a dial unit and a plunger, the dial unit being rotated to advance the plunger, which in turns advances the composition onto the applicator surface through the aperture therein.

7. A product according to claim 6 , wherein rotation of the dial unit in a first direction advances the plunger axially upwards, the plunger acting upon a piston seal at the base of a replaceable cartridge containing the composition and thereby forcing the contained composition upwards and outwards through the aperture in the applicator surface; rotation of the dial unit in a second direction, counter to the first, rotationally re-setting the dial unit relative to the plunger in readiness for a further advancement of the plunger, rotation in the second direction not causing significant axial movement of the plunger.

8. A product according to claim 6 , comprising stop faces that restrict rotational movement of the dial unit in its first direction to less than 180°.

9. A product according to claim 4 , wherein the reservoir is a replaceable refill cartridge.

10. A product according to claim 9 , comprising a passageway from the replaceable refill cartridge to the applicator surface, terminating at the aperture in the applicator surface and having a minimum cross-sectional area of at least 1.0 mm 2 .

11. A product according to claim 1 , wherein the composition is transferred from onto the applicator surface in unit doses.

12. A product according to claim 1 , wherein the non-pore blocking inhibitor of perspiration is an anticholinergic agent.

13. A product according to claim 1 , wherein the non-pore blocking inhibitor of perspiration is oxybutynin.

14. A product according to claim 1 , wherein the composition comprises from 1 to 5% by weight of the non-pore blocking inhibitor of perspiration.

15. A product according to claim 1 , wherein the viscosity of the composition is from 3500 mPa·s to 5000 mPa·s a shear rate of 16/s.

16. A product according to claim 15 , wherein the viscosity of the composition is from 4000 mPa·s to 4600 mPa·s a shear rate of 16/s.

17. A Product according to claim 1 , for use in treating perspiration, in particular excessive perspiration.

18. A product according to claim 1 , wherein the replaceable cartridge may be removed from the outer body or a refill holder within the outer body by means of a removable applicator head bearing the convex applicator surface at its top.

19. A cosmetic method of controlling perspiration, in particular excessive perspiration, wherein the method comprises the use of a product according to claim 1 .
