A clear print varnish composition for application as a coating on paper products which comprises a water based or a water soluble and at least one plant compound, said plant compound being an insect repellent, antifeedant or oviposition deterrent and accepted for food use and is present in an amount of 0.01% to 0.3% by weight of the print varnish.
A clear print varnish composition comprising the following ingredients in the percentage by weight amounts indicated:
- ______________________________________ Acrylic polymer 66% Styrene acrylic polymer 26% in water Defoamer 1.0% polyethylene wax emulsion 5.0% Silicone emulsion 0.1% Ethanol 1.0% Water 0.6-0.8% D-Limonene 0.01-0.28% Pinene 0.01-0.28% Cineole 0.01-0.28% ______________________________________
- wherein the total amount of D-Limonene, Pinene and Cineole together does not exceed 0.3% by weight of the print varnish composition.
A clear print varnish composition comprising the following ingredients in the percentage by weight amounts indicated:
- ______________________________________ Acrylic polymer 66% Styrene acrylic polymer 26% in water Defoamer 1.0% Polyethylene wax emulsion 5.0% Silicone emulsion 0.1% Ethanol 1.0% Water 0.6-0.8% Perillaldehyde 0.01-0.28% Cuminaldehyde 0.01-0.28% Linalool 0.01-0.28% ______________________________________
- wherein the total amount of Perillaldehyde, Cuminaldehyde and Linalool together does not exceed 0.3% by weight of the print varnish composition.
A clear print varnish composition comprising the following ingredients in the percent by weight amounts indicated:
- ______________________________________ Acrylic polymer 62% Styrene acrylic polymer 20% Butyl cellosolve 3.0% Surfactant/wetting agent 3.0% Defoamer 0.5% Ethanol 3.0% Polyethylene wax emulsion 5.0% Silicone emulsion 0.1% Water 2.1-2.4% D-Limonene 0.01-0.28% Pinene 0.01-0.28% Cineole 0.01-0.28% ______________________________________
- wherein the total amount of D-Limonene, Pinene and Cineole together does not exceed 0.3% by weight of the print varnish composition.
A clear print varnish composition comprising the following ingredients in the percentage by weight amounts indicated:
- ______________________________________ Acrylic polymer 62% Styrene acrylic polymer 20% Butyl cellosolve 3.0% Surfactant/wetting agent 3.0% Defoamer 0.5% Ethanol 3.0% Polyethylene wax emulsion 5.0% Silicone emulsion 0.1% Water 2.1-2.4% Perillaldeyde 0.01-0.28% Cuminaldehyde 0.01-0.28% Linalool 0.01-0.28% ______________________________________
- wherein the total amount of Perillaldehyde, Cuminaldehyde and Linalool together does not exceed 0.3% by weight of the print varnish composition.
A method of manufacturing a clear print varnish composition which comprises
- (a) mixing at least one plant compound which is insect repellent, antifeedant or oviposition deterrent and accepted for food use in an alcohol selected from the group consisting of ethanol, propyl alcohol and isopropyl alcohol, and;
- (b) mixing the alcohol and the at least one plant compound in a water-based or water soluble polymer which forms a coating on a container to be protected from the insect to produce the print varnish composition, wherein the at least one plant compound is present in a total amount of from 0.03% to 0.3% by weight of the print varnish composition.
A method of manufacturing an insect repellent, antifeedant or oviposition deterrent, clear print varnish composition which comprises
- (a) mixing more than one plant compound selected from the group consisting of Cuminaldehyde, Pinene, Limonene, Eucalyptol, Perillaldehyde, Linalool, Turmeric and Cinnamon oil and mixtures thereof, in amounts from 0.03% to 0.3% by weight of the print varnish and wherein all of the plant compounds together are 0.3% or less of the print varnish and an alcohol selected from the group consisting of ethanol, propyl alcohol and isopropyl alcohol to dissolve the plant compound;
- and
- (b) mixing the alcohol and plant compounds in a water-based or water soluble polymer which is a mixture of acrylic and styrene acrylic polymers to produce the print varnish.
A method for providing insect repellence, oviposition deterrent or antifeedant properties for a container which comprises applying a print varnish composition on the container which contains a polymer which forms a coating on the container and which coating contains at least one plant compound which provides the insect repellence, the oviposition deterrence or the antifeedant properties and is accented for food use in an amount from 0.01% to 0.3% by weight of the print varnish, wherein the total amount of the at least one plant compound is 0.3% or less by weight of the print varnish.
