Abstract

A condom together with a lubrication composition, the lubricating composition containing a minimal amount of free water, and comprising one or more glycols, such that the glycols in the lubricant release heat and warmth when contacted with compositions containing free water.

Claims

1. A packaged condom comprising:

a male genital engaging tubular sheath having an inner surface and an outer surface together with a lubricating composition comprising glyceryl polymethacrylate and at least about 10% w/w propylene glycol and at least 30% w/w polyethylene glycol, wherein the amount of said polyethylene glycol is greater than the amount of said propylene glycol and minimal free water, wherein the lubricating composition is located on at least a portion of both the inner surface and the outer surface of the tubular sheath, wherein, when said condom is engaged on the genitalia of a male user, the lubricating composition warms upon contact with free water from bodily secretions of the user to provide a warming sensation to the user.

2. The condom of claim 1, wherein said lubricating composition further includes at least about 5% w/w glycerin.

3. The condom of claim 1, wherein the lubrication composition has the following formula:

20% w/w propylene glycol, 45% w/w polyethylene glycol, 25% w/w mixture of glyceryl polymethacrylate, propylene glycol and water, and 10% w/w glycerin 96%.

4. The condom of claim 3, produced by the process of applying from 0.45 g to 0.75 g of said lubricating composition to said outer surface, applying from 0.15 g to 0.45 g of said lubricating composition to said inner surface, then foil-wrapping said condom, wherein the amount of said lubricating composition applied to said outer surface is greater than the amount of said lubricating composition applied to said inner surface.

5. The condom of claim 1 wherein the lubricating composition contains no free water.

6. A packaged condom comprising:

a male genital engaging tubular sheath having an inner surface lubricated with a lubricating composition comprising glyceryl polymethacrylate and propylene glycol and at least about 30% w/w polyethylene glycol, wherein the amount of said polyethylene glycol is greater than the amount of said propylene glycol and minimal free water,

wherein, when said condom is in use and engaged on the genitalia of a male user, the lubricating composition mixes with free water from bodily secretions of the user in an exothermic reaction such that a warming sensation is provided to the user.

7. The packaged condom according to claim 6 wherein the lubricating composition comprises no free water.

8. The packaged condom according to claim 6, wherein the male genital engaging tubular sheath further comprises an outer surface lubricated with the lubricating composition.

9. The packaged condom according to claim 6, wherein the male genital engaging tubular sheath further comprises an outer surface lubricated with a second lubricating composition comprising one or more glycols and minimal free water such that the second lubricating composition will warm upon contact with free water.
