A method of destroying target microorganisms comprises the step of contacting at least one target microorganism with at least one low molecular weight silanol end group containing molecule. The silanol containing molecule is selected from silanols (R1R2R3SiOH), siloxanediols HO(R1R2SiO)nH or siloxan
A method of destroying target microorganisms comprises the step of contacting at least one target microorganism with at least one low molecular weight silanol end group containing molecule. The silanol containing molecule is selected from silanols (R1R2R3SiOH), siloxanediols HO(R1R2SiO)nH or siloxanols HO(R1R2SiO)nSiR1R2R3, where R1, R2 and R3 are selected from 1 to 4 carbon alkyl or fluoroalkyl moieties, or vinyl, or aryl groups and n is <6 . The silanol end group containing molecule can be triethylsilanol, diphenylmethylsilanol, t-butyldimethylsilanol, n-butyldimethylsilanol, n-propyldimethylsilanol, ethyldimethylsilanol, vinylphenylmethylsilanol, phenyldimethylsilanol, 3,3,3 trifluoro propyldimethylsilanol, benzyldimethylsilanol and phenethyldimethylsilanol, or mixtures thereof. A composition of matter includes a silanol end group containing molecule according to the invention blended with a polymer or dissolved in aqueous solution along with an ether-based cosolvent.

We claim: 1. A method of destroying target microorganisms, comprising the step of: contacting at least one target microorganism with at least one silanol end group containing molecule, wherein said silanol containing molecule comprises at least one selected from the group consisting of silanols (R1
We claim: 1. A method of destroying target microorganisms, comprising the step of: contacting at least one target microorganism with at least one silanol end group containing molecule, wherein said silanol containing molecule comprises at least one selected from the group consisting of silanols (R1R2R3SiOH), siloxanediols HO(R1R2SiO)nH and siloxanols HO(R1R2SiO)nSiR1R2R3,where R1, R2 and R3 are selected from 1 to 4 carbon alkyl or fluoroalkyl moieties, or vinyl, or aryl groups and n is 2)aR1R2SiOH, where Ar is any phenyl or substituted phenyl group such that the substitution has a molecular weight of 1 and R2 are Ar or alkyl or fluoro alkyl group with less than 4 carbons. 12. The method of claim 11, wherein said fragrant silanol is phenethyldimethylsilanol or benzyldimethylsilanol. 13. A composition of matter, comprising: a silanol end group containing molecule blended with a polymer or in aqueous solution along with an ether-based cosolvent, wherein said silanol end group containing molecule is selected from the group consisting of silanols (R1R2R3SiOH), siloxanediols HO(R1R2SiO)nH and siloxanols HO(R1R2SiO)nSiR1R2R3, where R1, R2 and R3 are selected from 1 to 4 carbon alkyl or fluoroalkyl moieties, or vinyl, or aryl groups and n is <6. 14. The composition of claim 13, wherein said silanol containing molecule comprises at least one selected from the group consisting of triethylsilanol, diphenylmethylsilanol, t-butyldimethylsilanol, n-butyldimethylsilanol, n-propyldimethylsilanol, ethyldimethylsilanol, vinylphenylmethylsilanol, phenyldimethylsilanol, 3,3,3 trifluoro propyldimethylsilanol, benzyldimethylsilanol and phenethyldimethylsilanol, or mixtures thereof. 15. The composition of claim 13, wherein said silanol containing molecule is dissolved in said aqueous solution along with a propylene glycol ether cosolvent. 16. The composition of claim 15, wherein said propylene glycol ether comprises propylene glycol n-propyl ether. 17. The composition of claim 13, wherein said silanol containing molecule comprises triethylsilanol. 18. The composition of claim 13, wherein said polymer is a hydroxy containing polymer. 19. The composition of claim 18, wherein said hydroxy containing polymer comprises a siloxane.
