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 thickened spreadable warming lubricant comprising:
glycerin in an amount from about 40 wt % to 60 wt %;
a polyhydric alcohol in an amount from about 40 to 60 wt %;
a non-ionic surfactant in an amount from about 0.1 to 3 wt %; and
a thickener that is compatible with the polyhydric alcohol, glycerin and moisture, in an amount from about 0.1 to 2 wt %,
wherein the thickened spreadable warming lubricant is substantially anhydrous, produces a thin lubricious layer on skin and a condom, and produces a warming effect upon contact with moisture, wherein the lubricant is substantially free of an insulating agent; and
wherein the thickener is a carbomer.
2. The thickened spreadable warming lubricant of claim 1 , wherein the polyhydric alcohol is propylene glycol.
3. The thickened spreadable warming lubricant of claim 1 , wherein the non-ionic surfactant is a polyoxyethylene sorbitan monoester.
4. The thickened spreadable warming lubricant of claim 1 , wherein the carbomer comprises a polyacrylate.
5. The thickened spreadable warming lubricant of claim 1 , wherein the warming lubricant has a thickness of 0.05 to 0.1 mm when applied to the surface of a latex condom.
6. The thickened spreadable warming lubricant of claim 1 , wherein the warming lubricant has a thickness of 0.01 to 0.1 mm when applied to skin.
7. A thickened spreadable warming lubricant consisting essentially of 48-52 wt % glycerin, 48-52 wt % propylene glycol, 0.1-2.0 wt % thickener, 0.1-1.0 wt % polyoxyethylene sorbitan monolaurate, and, optionally, about 0.3 wt % anti-microbial preservative, wherein the lubricant is substantially free of an insulating agent and wherein the lubricant generates a warming effect upon contact with moisture; and wherein the thickener is a carbomer.
8. A method of applying a thickened spreadable warming lubricant onto the internal and external surfaces of a latex condom, which method comprises:
a. contacting the latex condom with about 0.2 to 5 ml of the thickened spreadable warming lubricant, the lubricant comprising glycerin in an amount from about 40 wt % to 60 wt %, a polyhydric alcohol in an amount from about 40 wt % to 60 wt %, a non-ionic surfactant in an amount from about 0.1 wt % to 3 wt % and a thickener that is compatible with the polyhydric alcohol, glycerin and moisture, in an amount from 0.1%-2.0 wt %, wherein the lubricant is substantially free of an insulating agent and wherein the thickener is a carbomer;
b. packaging the condom, and wherein the thickened spreadable warming lubricant spreads onto the internal and external surfaces of the latex condom.
9. A method of applying a thickened spreadable warming lubricant on skin, the lubricant consisting essentially of: glycerin in an amount from about 40 wt % to 60 wt %; a polyhydric alcohol in an amount from about 40 to 60 wt %; a non-ionic surfactant in an amount from about 0.1 to 3 wt %; and a thickener that is a carbomer and compatible with the polyhydric alcohol, glycerin and moisture, in an amount from about 0.1 to 2 wt %, and the method comprising: applying one to five drops of the warming lubricant consistent with the degree of skin-generated or applied moisture present, wherein each drop has a volume of approximately 25 μl; and rubbing the lubricant to produce a warming sensation and lubricating effect, whereby the warming effect is generated by the contact between thickened warming lubricant and the moisture.
10. An article, comprising:
a condom; and
a layer on the condom of a mixture including a polyhydric alcohol in an amount from about 40 wt % to 60 wt %, glycerin in an amount from about 40 wt % to 60 wt %, a non-ionic surfactant in an amount from about 0.1 wt % to 3 wt % and a thickener that is a carbomer in an amount from 0.1%-2.0 wt %, wherein the lubricant is substantially free of an insulating agent
wherein the mixture produces a warming effect when the condom comes into contact with moisture.
11. The article of claim 10 , wherein the mixture is substantially anhydrous.
12. The article of claim 11 , comprising a package formed from materials substantially resistant to transmission of moisture and compatible with the mixture.
13. The article of claim 10 , wherein the polyhydric alcohol is propylene glycol.
14. The article of claim 10 , wherein the non-ionic surfactant is a polyoxyethylene sorbitan monoester.
15. The article of claim 10 , wherein the carbomer comprises a polyacrylate.
16. The article of claim 10 , wherein the layer of warming lubricant is sufficient to provide a thickness of 0.05 to 0.1 mm when applied to the surface of a latex condom.
17. The article of claim 10 , wherein the mixture includes an effective amount of an anti-microbial preservative.
18. The article of claim 10 , wherein the mixture produces heat upon contact with water.
19. The method of claim 8 , further comprising forming a layer of the thickened warming lubricant having a thickness of 0.05 to 0.1 mm on the surface of the latex condom.
20. A thickened spreadable warming lubricant consisting essentially of:
glycerin in an amount from about 40 wt % to 60 wt %;
a polyhydric alcohol in an amount from about 40 to 60 wt %;
a non-ionic surfactant in an amount from about 0.1 to 3 wt %; and
a thickener that is a carbomer and compatible with the polyhydric alcohol, glycerin and moisture, in an amount from about 0.1 to 2 wt %,
wherein the thickened spreadable warming lubricant is substantially anhydrous, produces a thin lubricious layer on skin or a condom, and produces a warming effect upon contact with moisture.
