- 8. A method in accordance with claim 1 in which said quaternary ammonium organosilane is 3-(trimethoxysilyl)propyldimethyltetradecyl ammonium chloride.
- 9. A method in accordance with claim 1 further comprising contacting said skin with a mixture of said quaternary ammonium organosilanes.
- 10. A method in accordance with claim 1 in which said microorganisms are member selected from the group consisting of gram-positive and gram-negative bacteria.
- 11. A method in accordance with claim 1 in which said microorganisms are viruses.
- 12. A method in accordance with claim 1 in which said microorganisms are fungi.
- 13. A method in accordance with claim 1 in which said microorganisms are a member selected from the group consisting of algae and mold.
- 14. A method in accordance with claim 1 in which said microorganisms are yeast.
- 15. A method in accordance with claim 1 in which said microorganisms are spores.
- 16. A method of reducing or eliminating the viable number of pathogens on skin and for an extended period of time, said method comprising contacting the skin with composition comprising water-soluble additives and a quaternary ammonium organosilane having the formula
- 17. A method in accordance with claim 16 in which R1 is a member selected from the group consisting of —CH2CH2OCH3 and —CH2CH2OCH2CH2CH3.
- 18. A method in accordance with claim 16 in which R1 is a member selected from the group consisting of —CH2CH2OH and —CH2CH2CH2CH(OH)CH3.
- 19. A method in accordance with claim 16 in which R1 is a member selected from the group consisting of —CH2CH2NH2 and —CH2CH2N(CH3)2.
- 20. A method in accordance with claim 16 in which said pathogens are members selected from the group consisting of gram-positive bacteria, gram-negative bacteria, viruses, algae, mold, yeast and spores.
- 21. A method in accordance with claim 16 in which the amount of said aqueous solution and said quaternary ammonium organosilane therein is sufficient to maintain said reduction or elimination of pathogens for 64 hours.
- 22. A method in accordance with claim 16 in which said quaternary ammonium organosilane is 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium chloride.
- 23. A method in accordance with claim 16 in which said quaternary ammonium organosilane is 3-(trimethoxysilyl)propyldidecylmethyl ammonium chloride.
- 24. A method in accordance with claim 16 in which said water-soluble additives are members selected from the group consisting of methyl alcohol, ethyl alcohol, and propyl alcohol, and constitute from 1% to 80% of said aqueous solution.
- 25. A method in accordance with claim 16 in which said composition is a soap.
- 26. A method in accordance with claim 16 in which said composition is a gel.
- 27. A method in accordance with claim 16 in which composition is a solid.
- 28. A method in accordance with claim 16 in which said quaternary ammonium organosilane constitutes 0.01 to 4 weight percent of said composition.
- 29. A method in accordance with claim 16 in which said water-soluble additives comprise a dye at 0.001 to 0.2 weight percent of said composition.
- 30. A method in accordance with claim 16 in which said water-soluble additives comprise a scent at 0.001 to 1.0 weight percent of said composition.
