Method of treating a material using a sol-gel derived composition
View Patent ↗Disclosed is a method and system that includes treating a material by applying a sol-gel derived composition loaded with a first sorbate under conditions effective to treat the material with the first sorbate.
1. A method of treating a material comprising the step of
applying an aromatically-bridged, organosiloxane sol-gel derived composition containing a plurality of alkylsiloxy substituents loaded with a first sorbate under conditions effective to treat the material with the first sorbate.
2. The method of claim 1 wherein the first sorbate is biologically active.
3. The method of claim 1 wherein the first sorbate is a pesticide, a herbicide or a pharmaceutical.
4. The method of claim 3 wherein the first sorbate is atrazine, 2,4-dichlorophenoxyacetic acid, malathion, dichlorodiphenyltrichloroethane, impramine, a vitamin or a polypeptide.
5. The method of claim 1 wherein the loading density of the sorbate in the sol-gel derived composition is from about 0.005 to about 5 gram sorbate per gram of the sol-gel derived composition.
6. The method of claim 2 wherein the loading density of the sorbate in the sol-gel derived composition is from about 0.005 to about 5 gram sorbate per gram of the sol-gel derived composition.
7. The method of claim 1 wherein the sol-gel derived composition is substantially completely loaded with the sorbate.
8. The method of claim 1 wherein the sol-gel derived composition is partially loaded with the sorbate.
9. The method of claim 8 further comprising applying a second sorbate after application of the first sorbate.
10. The method of claim 9 wherein the second sorbate is a water soluble organic liquid.
11. The method of claim 10 wherein the second sorbate is ethanol.
12. The method of claim 1 wherein the sol-gel derived composition is applied to a plant or an animal.
13. The method of claim 1 wherein the sol-gel derived composition is applied to a human.
14. The method of claim 1 wherein the sol-gel derived composition is applied to a soil.
15. The method of claim 1 further comprising applying an unloaded aromatically-bridged, organosiloxane sol-gel derived composition containing a plurality of alkylsiloxy substituents to the material along with the loaded sol-gel derived composition.
16. The method of claim 1 wherein the sol-gel derived composition includes inert particles having a diameter of from about 5 to about 20 nm.
17. The method of claim 16 where the inert particle is magnetic.
18. The method of claim 17 further comprising removing the sol gel-derived composition from the treated material with a magnetic device.
19. A composition of matter comprising:
an aromatically-bridged, organosiloxane sol-gel derived composition containing a plurality of alkylsiloxy substituents and a cosmetically acceptable carrier.
20. A composition of matter comprising:
a skin-care preparation, personal care preparation or light-protective preparation containing an aromatically-bridged, organosiloxane sol-gel derived composition containing a plurality of alkylsiloxy substituents.
21. A composition of matter comprising:
an aromatically-bridged, organosiloxane sol-gel derived composition containing a plurality of alkylsiloxy substituents and a non-liquid pharmaceutically effective carrier.
22. A composition of matter comprising:
a sorbate-loaded aromatically-bridged, organosiloxane sol-gel derived composition containing a plurality of alkylsiloxy substituents and a cosmetically acceptable carrier.
23. A composition of matter comprising:
a skin-care preparation, personal care preparation or light-protective preparations containing a sorbate loaded aromatically-bridged, organosiloxane sol-gel derived composition containing a plurality of alkylsiloxy substituents.
24. A composition of matter comprising:
an aromatically-bridged organosiloxane sol-gel derived composition containing a plurality of alkylsiloxy substituents loaded with a first sorbate and a non-liquid pharmaceutically effective carrier.
