Methods of inhibiting enveloped viruses using low molecular weight hydrophobically modified polymers
This invention relates to methods and compositions for inhibiting the transmission of enveloped viruses, which entails applying a composition containing a low molecular weight hydrophobically-modified polymer to an infectable or ingestible surface that may contain viruses, wherein said compositions further comprise less than about 9% by weight of surfactant having an HLB of greater than 12.
1. A method of inhibiting entry of enveloped viruses into cells of a subject comprising-applying an anti-viral composition to infectable surfaces of said subject, wherein said infectable surfaces comprise mucosal tissue of said subject, wherein said mucosal tissue comprises tissue selected from the group consisting of oral tissue, ocular tissue, nasal tissue, vaginal tissue, or rectal tissue and a combination thereof, wherein said anti-viral composition comprises at least one low molecular weight hydrophobically modified polymer in an amount effective to inhibit entry of viruses into cells, wherein said enveloped viruses is a Retrovirus,
wherein said low molecular weight hydrophobically modified polymer is potassium acrylates copolymer,
wherein said composition comprises from about 0.375% to about 9% by weight of surfactant having an HLB greater than 12,
wherein said composition comprises a dosage form selected from the group consisting of: a liquid, a lotion, a cream, a gel, a stick, a spray, an ointment, a paste, a powder, a mousse, a wipe, a patch, a hydrogel and a film.
2. A method according to claim 1 , wherein said composition comprises between about 0.375% and 6% by weight of surfactant.
3. A method according to claim 1 wherein said composition comprises between about 0.375% and 3% by weight of surfactant.
4. A method according to claim 1 wherein the TEP of said anti-viral composition is greater than about 3.8.
5. A method according to claim 1 wherein said low molecular weight hydrophobically modified polymer is present in said composition in an amount of from about 0.00005% to about 3% percent by weight of the composition.
6. A method according to claim 1 wherein said composition further comprises at least 55% of water.
7. A method according to claim 6 wherein said composition comprises at least 97% of water.
8. A method according to claim 1 wherein said inhibition of virus entry into said cells results in the reduction of potential for viral infection.
9. A method according to claim 1 wherein the anti-viral composition does not substantially disrupt biological surfaces.
10. An anti-viral composition comprising at least one low molecular weight hydrophobically modified polymers in an amount effective to inhibit entry of retrovirusues into cells and at least 55% water,
wherein said composition comprises from about 0.375% to about 9% by weight of surfactant having an HLB greater than 12,
wherein said low molecular weight hydrophobically modified polymer is potassium acrylates copolymer
wherein said composition comprises a dosage form selected from the group consisting of: a liquid, a lotion, a cream, a gel, a stick, a spray, an ointment, a paste, a powder, a mousse, a wipe, a patch, a hydrogel and a film.
11. A method of inhibiting the transmission of retrovirusues comprising applying to non-biological surfaces a composition comprising at least one low molecular weight hydrophobically modified polymers in an amount effective to inhibit entry of viruses into cells wherein said composition comprises from about 0.375% to about 9% by weight of surfactant having an HLB greater than 12,
wherein said low molecular weight hydrophobically modified polymer is potassium acrylates copolymer.
12. A method of inhibiting the transmission of retrovirusues comprising applying to infectable surfaces a composition comprising at least one low molecular weight hydrophobically modified polymers in an amount effective to inhibit entry of viruses into cells wherein said composition comprises from about 0.375% to about 9% by weight of surfactant having an HLB greater than 12, wherein said low molecular weight hydrophobically modified is potassium acrylates copolymer.
13. A composition according to claim 12 wherein said composition further comprises from about 0.375% to about 9% by weight of surfactant selected from the group consisting of anionic, cationic, nonionic and amphoteric surfactants.
14. The method of claim 1 , wherein the retrovirus is HIV.
