Abstract

A dispenser for petroleum distillate based household products, such as furniture oil, baby oil, or the like, comprises a non-pressurized spray bottle comprising a reduced volume spray apparatus which dispenses less than about 0.8 ml per actuation, and a removal resistant neck closure which does not permit closure removal or easy opening of the container. Lower risk is also obtained by addition of a thixotropic thickener to the petroleum distillate based product, to provide a product having a viscosity of greater than 100 SUS at rest at 100° F., but which exhibits shear-thinning, so as to be capable of being dispensed as a spray or fine mist by a non-pressurized spray dispenser or pump. Still further risk lowering may be attained by the addition of an effective amount of a bittering or aversion agent so as to substantially discourage voluntary ingestion of the petroleum distillate based product.

Claims

1. A method for dispensing a petroleum distillate based household product, comprising dispensing said product from a container having a reduced volume spray mechanism and a removal resistant neck closure, wherein the improvement comprises adding to said product a shear-thinning thixotropic thickener.

2. The method of claim 1, wherein said reduced volume spray mechanism dispenses less than about 0.8 ml of liquid per actuation, and said product comprises a petroleum distillate chosen from the group consisting of mineral oils, mineral spirits, naphthenic oils, silicone oils, isoparaffinic hydrocarbon solvents, kerosene, and mixtures thereof.

3. The method of claim 2, wherein said petroleum distillate product has a viscosity of from about 30 to about 130 SUS at 100°

F. prior to addition of the thickener, and a viscosity of greater than about 100 SUS at 100°

F. subsequent to the addition of the thickener, and said product containing said thickener forms a spray upon passage through said spray mechanism.

4. The method of claim 3, wherein said thickener is chosen from the group consisting of a mixture comprising a triblock copolymer and a hydrocarbon oil, and N-Lauroyl glutamic acid di-n-butylamide, and comprises from about 0.2 to about 9 percent by weight of the product.

5. The method of claim 4, wherein said thickener comprises from about 2 percent to about 30 percent triblock copolymer and from about 70 percent to about 98 percent hydrocarbon oil.

6. The method of claim 5, wherein said product comprises a furniture oil.

7. The method of claim 6, wherein said furniture oil comprises a mineral oil and a silicone oil.

8. The method of claim 2, wherein the improvement further comprises adding to said product an aversion agent.

9. The method of claim 8, wherein the aversion agent is selected from the group consisting of denatonium benzoate, denatonium saccharide, denatonium chloride, sucrose benzoate, quinine, quinine hydrochloride, quinine sulfate, brucine, brucine sulfate, quassia, quassin, naringin, limonin, phenylthiocarbamide, quebracho, sucrose octaacetate, quercetin, berberine, and combinations thereof.

10. The method of claim 9, wherein the aversion agent is present in an amount of from about 0.0010 to about 0.050 percent by weight.

11. The method of claim 10, wherein the aversion agent is denatonium benzoate.

12. The method of claim 11, wherein the denatonium benzoate is present in an amount of from about 0.0025 to about 0.010 percent by weight.

13. A method for the dispensing of a petroleum distillate product selected from the group consisting of mineral oils, mineral spirits, naphthenic oils, silicone oils, isoparaffinic hydrocarbon solvents, and mixtures thereof, said method comprising applying said product to a surface by means of a reduced volume spray mechanism having a removal resistant neck closure, wherein said mechanism dispenses less than about 0.8 ml of liquid per actuation.

14. The method of claim 13, further comprising adding to said product a shear-thinning thixotropic thickener comprising from about 2 percent to about 30 percent triblock copolymer and from about 70 percent to about 98 percent hydrocarbon oil.

15. The method of claim 13, wherein said petroleum distillate product has a viscosity of from about 30 to about 130 SUS at 100°

F. prior to addition of said thickener, and a viscosity of greater than about 100 SUS at 100°

F. subsequent to the addition of said thickener, and said product containing said thickener forms a spray upon passage through said spray mechanism.

16. The method of claim 14, further comprising adding to said product an aversion agent.

17. The method of claim 16, wherein the aversion agent is selected from the group consisting of denatonium benzoate, denatonium saccharide, denatonium chloride, sucrose benzoate, quinine, quinine hydrochloride, quinine sulfate, brucine, brucine sulfate, quassia, quassin, naringin, limonin, phenylthiocarbamide, quebracho, sucrose octaacetate, quercetin, berberine, and combinations thereof.

18. The method of claim 17, wherein the aversion agent is present in an amount of from about 0.0010 to about 0.050 percent by weight.

19. The method of claim 18, wherein the aversion agent is denatonium benzoate.

20. The method of claim 19, wherein the denatonium benzoate is present in an amount of from about 0.0025 to about 0.010 percent by weight.
