Abstract
A packaged condom may include a sealed package and, within the package, a condom including natural rubber latex and/or synthetic polyisoprene. The condom includes an aqueous lubricant on one or more surfaces thereof. The aqueous lubricant is in contact with the natural rubber latex and/or synthetic polyisoprene. The aqueous lubricant includes a thickener and one or more organic compounds in a total amount of from 5 to 25% by weight of the aqueous lubricant, the one or more organic compounds independently selected from a poly-hydric alcohol and a sugar. Each of the one or more organic compounds may have at least 4 hydroxyl groups and a molecular weight of from 120 to 10000.
Claims19
A packaged condom comprising:
- a sealed package;
- and
- within the sealed package, a condom comprising natural rubber latex and/or synthetic polyisoprene;
- wherein the condom further comprises an aqueous lubricant on one or more surfaces thereof, the aqueous lubricant in contact with the natural rubber latex and/or synthetic polyisoprene,
- wherein the aqueous lubricant comprises:
- a thickener;
- and
- one or more organic compounds in a total amount of from 5 to 25% by weight of the aqueous lubricant, the one or more organic compounds independently selected from the group consisting of a polyhydric alcohol and a sugar, each of said one or more organic compounds having at least 4 hydroxyl groups and a molecular weight of from 180 to 10000.
A method for preparing a packaged condom, the method comprising:
- (i) providing an aqueous lubricant, wherein the aqueous lubricant comprises a thickener and, one or more organic compounds in a total amount of from 5 to 25% by weight of the aqueous lubricant, the one or more organic compounds independently selected from the group consisting of a polyhydric alcohol and a sugar, each of said one or more organic compounds having at least 4 hydroxyl groups and a molecular weight of from 180 to 10000;
- (ii) providing a condom comprising natural rubber latex and/or synthetic polyisoprene;
- (iii) applying a dose of the aqueous lubricant to one or more surfaces of the condom such that the aqueous lubricant is in contact with the natural rubber latex and/or synthetic polyisoprene;
- and
- (iv) sealing the condom within a package.
A method of using an aqueous lubricant to lubricate one or more surfaces of a condom comprising natural rubber latex and/or synthetic polyisoprene while maintaining a transparency of the condom during storage within a sealed package, the method comprising applying the aqueous lubricant to one or more surfaces of the condom such that the aqueous lubricant is in contact with the natural rubber latex and/or synthetic polyisoprene,
- wherein the aqueous lubricant comprises a thickener and, in a total amount of from 5 to 25% by weight of the aqueous lubricant, one or more organic compounds independently selected from the group consisting of a polyhydric alcohol and a sugar, wherein each of the one or more organic compounds has at least 4 hydroxyl groups and a molecular weight of from 180 to 10000.
