Abstract
The present invention includes pourable, non-toxic lubricating compositions containing carrageenan and more precisely λ carrageenan as an anti-viral agent, for protection from Human Papillomavirus (HPV), and methods of using the lubricating compositions as a non-oily, psuedoplastic lubrication product and administering the carrageenan for reducing the propagation of HPV during sexual activity.
Claims20
A method for forming an antiviral lubricous composition, comprising the steps of:
- (a) providing a carrageenan powder comprising carrageenan, the carrageenan comprising about 90% by weight lambda-carrageenan and about 10% by weight kappa-carrageenan;
- (b) mixing the carrageenan powder with a solution comprising propylene glycol, forming an aqueous carrageenan suspension;
- (c) heating the aqueous carrageenan suspension up to a temperature of at least about 70° C. and up to about 75° C.;
- (d) mixing the heated aqueous carrageenan suspension for a time sufficient to form an aqueous homogenous solution having a turbidity that is less than or equal to about 25 Nephelometric Turbidity Units (NTU);
- (e) cooling the aqueous homogeneous solution to a temperature of less than about 30° C.;
- and
- (f) mixing in one or more pH-adjusting agents, in an amount sufficient to adjust the antiviral lubricous composition to a pH of about 3.5 to about 7.0.
