Abstract

Pad consisting of a porous support, on one face of which is applied a layer of gel having a refreshing action on the skin to which it is applied, dispersed within the gel there being substances of various kinds having aromatic and/or balsamic, cosmetic or therapeutic activity, the support being formed from a layer of natural or synthetic fibres forming a fabric of non-woven type or a fabric possibly coupled to a plastic film.

Claims

1. Pad for application to the human skin, to develop a decongestant, cosmetic and/or pharmaceutical action, consisting of a flexible porous support, on at least one surface of which is applied a layer of gel consisting of an intimate mixture comprising between 50% and 77% of water, between 6.5% and 44% of a dermatologically compatible polymer, between 0% and 10% of a substance of plant origin comprising essential oils and aromatic extracts;

and between 0% and 10% of at least one dermatologically compatible component chosen from the group comprising soothing, skin repairing, cicatrising, anti-inflammatory, antiseptic and bactericidal substances, the percentages being by weight.

2. Pad as claimed in claim 1, wherein said gel comprises between 0.01% and 5.2% of an alkaline or alkaline earth metal tetraborate, the percentages being by weight.

3. Pad as claimed in claim 1, wherein said support consists of a non-woven fabric made of fibres chosen from the group consisting of viscose, polyester and polyethylene fibres, mixed polyester/viscose fibres, cotton and linen, said fabric support having a thickness between 15 and 200 microns, a density from 65 to 145 g/dm³ and a weight between 15 and 150 g/m².

4. Pad as claimed in claim 1, wherein said gel comprises between 0.001-% and 5.2% of at least one dermatologically compatible auxiliary component chosen from the group consisting of solvents, wetting agents, preservatives, emulsifiers, stabilizers, solubilizers, surfactants, colorants, the percentages being by weight.

5. Pad as claimed in claim 2, wherein said gel comprises between 0.001% and 5.2% of at least one dermatologically compatible auxiliary component chosen from the group consisting of solvents, wetting agents, preservatives, emulsifiers, stabilizers, solubilizers, surfactants, colorants, the percentages being by weight.

6. Pad as claimed in claim 3, wherein said gel comprises between 0.001% and 5.2% of at least one dermatologically compatible auxiliary component chosen from the group consisting of solvents, wetting agents, preservatives, emulsifiers, stabilizers, solubilizers, surfactants, colorants, the percentages being by weight.

7. Pad as claimed in claim 1, wherein said flexible porous support is impregnated with said substance of plant origin, present in a quantity between 0% and 10% by weight on the total weight of the gel applied to the support.

8. Pad as claimed in claim 2, wherein said flexible porous support is impregnated with said substance of plant origin, present in a quantity between 0% and 10% by weight on the total weight of the gel applied to the support.

9. Pad as claimed in claim 3, wherein said flexible porous support is impregnated with said substance of plant origin, present in a quantity between 0% and 10% by weight on the total weight of the gel applied to the support.

10. Pad as claimed in claim 4, wherein said flexible porous support is impregnated with said substance of plant origin, present in a quantity between 0% and 10% by weight on the total weight of the gel applied to the support.
