## Abstract

The aim of the present invention is to provide a fluid composition that can form a coating, said composition being characterized in that it contains, at least in a solvent medium, an effective amount of at least one natural virucide selected from among lauric acid, monolaurin, lactoferrin and essential oils having antiviral activity and/or one of the precursors thereof, said composition having a viscosity of 30 mPa·s to 40 Pa·s at room temperature and pressure.

## Claims

### Claim 1

A fluid composition capable of forming a coating comprising:
an effective amount of at least one virucide selected from the group consisting of lauric acid, monolaurin, lactoferrin, essential oils having an antiviral activity and precursors thereof;
wherein the composition has a viscosity between 30 mPa·s and 40 Pa·s, at room temperature and ambient pressure.

### Claim 2 (depends on 1)

The composition of claim 1, further comprising at least one biocide selected from the group consisting of bacteriostatic biocide, bactericidal biocide, fungistatic biocide and fungicidal biocide.

### Claim 3 (depends on 1)

The composition of claim 1, wherein the virucide is active against human pathogenic viruses.

### Claim 4 (depends on 1)

The composition of claim 1, wherein the virucide is present in the composition from 0.1% to 3% w/w.

### Claim 5 (depends on 1)

The composition of claim 1, further comprising humectant.

### Claim 6 (depends on 5)

The composition of claim 5, wherein the humectant is a polyol.

### Claim 7 (depends on 1)

The composition of claim 1, wherein weight ratio of mass of the humectant to mass of the virucide is at least equal to 1.

### Claim 8 (depends on 1)

The composition of claim 1, further comprising at least one binder.

### Claim 9 (depends on 8)

The composition of claim 8, wherein the binder is selected from the group consisting of resins, waxes and gums.

### Claim 10 (depends on 1)

The composition of claim 1, wherein the coating is selected from the group consisting of ink and varnish.

### Claim 11 (depends on 10)

The composition of claim 10, wherein the ink is comprised of at least one pigment and at least one binder wherein the at least one binder is selected from the group consisting of a polyethylene wax, an acrylic resin and mixtures thereof.

### Claim 12 (depends on 11)

The composition of claim 11, wherein the ink is comprised of between 0% and 60% w/w of the pigment.

### Claim 13 (depends on 10)

The composition of claim 10, wherein the varnish is comprised at least one binder selected from the group consisting of a polyethylene wax, an acrylic resin and mixtures thereof.

### Claim 14 (depends on 13)

The composition of claim 13, wherein the varnish is an overprint varnish comprised of at least one binder wherein the at least one binder is a cycloaliphatic epoxy resin.

### Claim 15

A method of coating a surface of a support with a virucidal layer comprising:
providing a support having a surface to be treated and
applying a fluid composition having an effective amount of at least one virucide to the surface of the support;
