Thickened spreadable warming lubricant
A substantially anhydrous, thickened, spreadable, warming lubricant composition comprising a mixture of glycerin, polyhydric alcohol, a non-ionic surfactant, and a Carbomer thickener, the surfactant improving wetting and spreadability of the composition on skin and latex, and the thickener providing a creamy rich feel to the composition, such that the composition can be applied to skin or a condom and provide an optimal warming effect upon contact with ambient moisture during use and such that the composition can be added to a condom package and, over the course of a week, spread and coat nearly the entire internal and external surfaces of the condom.
1. A method of using a lubricant, the method comprising:
placing an amount of a thickened spreadable warming lubricant on moist skin, the thickened spreadable warming lubricant comprising glycerin, a polyhydric alcohol, a non-ionic surfactant, and a thickener that comprises carbomer;
forming a thickness of the lubricant in the range of 0.01 to 0.1 mm on the moist skin due to the spreadable nature of the lubricant; and
generating heat upon contact of the lubricant with the moist skin.
2. The method of claim 1 , wherein the amount is in the range of 0.2 to 5 mL.
3. The method claim 1 , wherein a drop of the lubricant in the amount of 25 μL spreads to a diameter of at least 6 mm after about 1 minute on the moist skin.
4. The method of claim 1 , wherein a contact angle between the lubricant and the moist skin is about 56° or less after about 1 minute on the moist skin.
5. The method of claim 1 , wherein the heat results in a temperature rise of at least 6° C.

7. The method of claim 1 , wherein the lubricant consists essentially of 48-52 wt % glycerin, 48-52 wt % propylene glycol, 0.1-2.0 wt % carbomer thickener, 0.1-1.0 wt % polyoxyethylene sorbitan monolaurate, and a preservative.
8. A thickened spreadable warming lubricant comprising:
a first polyhydric alcohol having a first viscosity in an amount in the range of 40 wt % to 60 wt %;
a second polyhydric alcohol having a second viscosity in an amount in the range of 40 wt % to 60 wt %;
a non-ionic surfactant in an amount in the range of 0.1 wt % to 3 wt %; and
a thickener that comprises carbomer, the carbomer in an amount in the range of 0.1 wt % to 2 wt %,
wherein the thickened spreadable warming lubricant is substantially anhydrous, produces a thin lubricious layer on skin, and produces a warming effect upon contact with moisture.
9. The thickened spreadable warming lubricant of claim 8 , wherein the first polyhydric alcohol comprises glycerin.
10. The thickened spreadable warming lubricant of claim 8 , wherein the second polyhydric alcohol comprises polypropylene glycol.
11. The thickened spreadable warming lubricant of claim 8 , wherein the non-ionic surfactant is a polyoxyethylene sorbitan monoester.
12. The thickened spreadable warming lubricant of claim 8 , wherein the carbomer comprises a polyacrylate.
13. The thickened spreadable warming lubricant of claim 8 being provided in a package having a volume in the range of 0.2 to 5 mL.
14. The thickened spreadable warming lubricant of claim 8 wherein the first viscosity of the first polyhydric alcohol measured at 25° C. is in the range of 500 to 600 centipoise.
15. The thickened spreadable warming lubricant of claim 8 wherein the second viscosity of the second polyhydric alcohol measured at 25° C. is in the range of 25 to 40 centipoise.
16. The thickened spreadable warming lubricant of claim 8 wherein the viscosity of the lubricant measured at 25° C. is at least 1400 centipoise.
17. The thickened spreadable warming lubricant of claim 8 wherein the viscosity of the lubricant measured at 25° C. is in the range of 1400 to 1450 centipoise.
18. A thickened spreadable warming lubricant comprising:
a first polyhydric alcohol, in an amount in the range of 48 wt % to 52 wt %;
a second polyhydric alcohol, in an amount in the range of 48 wt % to 52 wt %;
a non-ionic surfactant in an amount in the range of 0.1 wt % to 1 wt %; and
a thickener in an amount in the range of 0.1 wt % to 2 wt %,
wherein
the thickened spreadable warming lubricant is substantially anhydrous, produces a thin lubricious layer on skin, and produces a warming effect upon contact with moisture,
the viscosity of the lubricant measured at 25° C. is at least 1400 centipoise,
a drop of the lubricant in the amount of 25 μL spreads to a diameter of at least 6 mm after about 1 minute on the moist skin, and
a contact angle between the lubricant and the moist skin is about 56° or less after about 1 minute on the moist skin.
19. The thickened spreadable warming lubricant of claim 18 wherein the viscosity of the lubricant measured at 25° C. is in the range of 1400 to 1450 centipoise.
20. The thickened spreadable warming lubricant of claim 19 wherein the wherein the lubricant consists essentially of 48-52 wt % the first polyhydric alcohol having a viscosity in the range of 500 to 600 centipoise as measured at 25° C., 48-52 wt % the second polyhydric alcohol having a viscosity in the range of 25 to 40 centipoise as measured at 25° C., 0.1-2.0 wt % thickener, 0.1-1.0 wt % non-ionic surfactant, and a preservative.
