<p>A process for making parasite repellent absorbent material, comprising:
a). dosing an absorbent material with a solution or suspension, said solution or suspension comprising at least one primary solvent and at least one parasite repellent to achieve a desired loading of the at least one parasite repellent ;
b). drying the dosed absorbent material so that the at least one primary solvent evaporates; and
c). storing the dried absorbent material away from direct sunlight for at least 12 hours to form parasite repellent absorbent material. The solution or suspension sprayed onto the absorbent material may additionally comprise at least one secondary solvent that is less volatile than the at least one primary solvent. The parasite repellent absorbent material produced by this process may be used to make a parasite repellent product, such as a parasite repellent collar or a parasite repellent bed liner.</p> |
