Abstract
Grease-like compositions are provided for repelling rodents. The compositions utilize nontoxic mineral, synthetic, or vegetable oil based gels containing silica, clay, urea, polytetrafluoroethylene, or metallic soap thickeners and capsaicin.
Claims14
A rodent repelling composition comprising:
- 70 to 95 wt. % of a base oil, wherein the base oil comprises an oil selected from the group consisting of silicone oil, white oil, and combinations thereof;
- 3.0 to 20 wt. % of a thickening agent;
- 2.0 to 20 wt. % of a high viscosity polyalphaolefin;
- 0.025 to 0.1 wt. % of a repellent agent selected from the group consisting of capsaicin, dihydrocapsaicin, nordihydrocapsaicin, homodihydrocapsaicin, homocapsaicin, nonivamide, vanillylamide of n-nonanoic acid, piperine, allyl isothiocyanate, allicin, and combinations thereof;
- and
- 0.25 to 5 wt. % of a solubility improving additive.

A method of repelling a rodent, comprising:
- applying a rodent repelling composition to a surface in an area wherein rodents are to be repelled, the composition comprising 70 to 88 wt. % of a base oil, wherein the base oil comprises an oil selected from the group consisting of silicone oil, white oil, and combinations thereof, 5.0 to 12.0 wt. % of a thickening agent, 5.0 to 10.0 wt. % of a high viscosity polyalphaolefin, 0.025 to 0.10 wt. % of a repellent agent selected from the group consisting of capsaicin, piperine, allyl isothiocyanate, allicin, and combinations thereof, and 1.0 to 2.0 wt. % of a solubility improving additive, whereby rodents are repelled.
