Abstract

Warming personal lubricant compositions, condom products including such compositions and methods of making such condom products are disclosed. The present warming lubricant compositions include at least about 50% by weight of a polyalkylene glycol component, preferably including at least two portions of different molecular weights, and an effective amount of a viscosity inducing component.

Claims

1. A method of using a lubricant, the method comprising:

placing an effective lubricating amount of a warming lubricant composition on a moist part of a living human body, the warming lubricant composition comprising a first polyalkylene glycol component portion having a first molecular weight, a second polyalkylene glycol component portion having a second molecular weight reduced relative to the first molecular weight, and an effective amount of a viscosity inducing component other than a cellulosic derivative, the first and second polyalkylene glycol component portions together comprising at least about 50% by weight of the warming lubricant composition which is substantially clear and substantially anhydrous, the warming lubricant composition being effective to generate heat when placed on the moist part of the living human body.

2. The method of claim 1, wherein the first and second polyalkylene glycol component portions together comprise at least about 80% by weight of the composition.

3. The method of claim 1, wherein the first polyalkylene glycol component portion has a molecular weight in a range of about 350 to about 450 and the second polyalkylene glycol component portion has a molecular weight in a range of about 150 to about 250.

4. The method of claim 1, wherein the viscosity inducing component comprises a polyvinylpyrrolidone component.

5. The method of claim 4, wherein the polyvinylpyrrolidone component comprises a first polyvinylpyrrolidone component portion and a second polyvinylpyrrolidone component portion having a different molecular weight than the first portion.
