Patent ID: 7863230

Claim:
A lubricant composition comprising: a first polyethylene glycol component portion having a first molecular weight range; and a second polyethylene glycol component portion having a second molecular weight range reduced relative to the first molecular weight range; and an effective amount of a viscosity inducing component comprising a first polyvinylpyrrolidone component portion and a second polyvinylpyrrolidone component portion having a different average molecular weight than the first polyvinylpyrrolidone portion, wherein the first and second polyvinylpyrrolidone component portions together are present in a combined concentration of from about 1% to about 15% by weight, the first and second polyethylene glycol component portions together comprise at least about 50% by weight of the composition and the second polyethylene glycol component portion is present in a greater amount by weight than the first polyethylene glycol component portion, the composition being substantially clear, uniform, smooth and substantially anhydrous, and being effective to generate heat when placed in contact with water, wherein the weight ratio of the second polyethylene glycol component portion to the first polyethylene glycol component portion is from 1.1 to about 6.7, and wherein said lubricant composition is substantially non-toxic and suitable for application as a personal lubricant to human skin or mucosal surfaces without causing undue irritation or harm, to increase pleasure during intimate activities.
