Substantially anhydrous sprayable personal lubricant
View Patent ↗This invention relates to personal lubricant compositions that are capable of being sprayed to a targeted area while maintaining lubricity.
1. A method of providing personal lubrication comprising (a) placing a sprayable anhydrous personal lubricant composition for application to the skin or mucous membranes of a mammal in a swirl chamber pump spray mechanism and (b) dispensing said composition as a target spray to a target area from a distance of, wherein the sprayable anhydrous personal lubricant composition for application to the skin or mucous membranes of a mammal has a warming effect when so applied and consists essentially of at least 50% by weight of propylene glycol and at least one polyethylene glycol wherein the composition has a viscosity less than about 250 cps and a lubricity of at least 8 as determined by the Ahmad procedure, is lubricious, and upon spraying from a swirl chamber pump spray mechanism, the composition is atomized into particles having a particle size distribution at a 3″ spray distance of at least about 400 μm in the 10 th percentile, at least about 40 μm in the 50 th percentile and at least about 100 μm in the 90 th percentile and at 6″, at least about 200 μm in the 10 th percentile, at least about 40 μm in the 50 th percentile and at least about 75 μm in the 90 th percentile.
2. A method of providing personal lubrication in accordance with claim 1 wherein the viscosity of the composition is from about 10 to about 150 cps.
3. A method of providing personal lubrication in accordance with claim 1 wherein the polyethylene glycol has repeating ethylene glycol units of about 300 to about 1450.
4. A method of providing personal lubrication in accordance with claim 1 wherein said swirl chamber pump spray mechanism dispenses said composition in a conical-shaped pattern.
5. A method of providing personal lubrication in accordance with claim 1 wherein said composition consists essentially of (a) a compound selected from the group consisting of polyethylene glycol 400, polyethylene glycol 1000, polyethylene glycol 1450 or a mixture thereof; and (b) propylene glycol.
