Claims
- 1. A method of dry cleaning articles comprising the acts of:
- (a) immersing said articles to be dry cleaned in a composition including a siloxane solvent and an ionic organo-silicone-based detergent;
- (b) agitating said articles in said composition; and
- (c) removing said composition from said articles.
- 2. The method recited in claim 1, wherein said composition comprises a siloxane solvent selected from the group consisting of pentamer, tetramer, and hexamer cyclic siloxanes.
- 3. The method recited in claim 1, wherein said composition further comprises at least one additive selected from the group consisting of disinfectants, surfactants, suspending agents and brighteners.
- 4. The method recited in claim 1, wherein said organo-silicone-based detergent comprises a backbone with between 1 and 300 moles of polar fingers per molecule.
- 5. The method recited in claim 1, wherein said organo-silicone-based detergent comprises a backbone with polar fingers between 20% and 90% by weight.
- 6. The method recited in claim 1, wherein said organo-silicone-based detergent comprises a backbone with a hydrophilic/lipophilic balance of between 4 and 18.
- 7. The method recited in claim 1, wherein said organo-silicone-based detergent comprises a backbone with ethylene oxide polyether polar fingers.
- 8. The method recited in claim 1, wherein said organo-silicone-based detergent comprises a backbone with ethylene oxide and propylene oxide polyether polar fingers.
- 9. The method recited in claim 1, wherein said organo-silicone-based detergent comprises a backbone with linear organic polyethers of ethylene oxide as polar fingers.
- 10. The method recited in claim 8, wherein said fingers are ionic.
- 11. The method recited in claim 2, wherein said organo-silicone-based organic based detergent comprises a backbone with between 1 and 300 moles of polar fingers per molecule.
- 12. The method recited in claim 2, wherein said organo-silicone-based detergent comprises a backbone with polar fingers between 20% and 90% by weight.
- 13. The method recited in claim 2, wherein said organo-silicone-based detergent comprises a backbone with a hydrophilic/lipophilic balance of between 4 and 18.
- 14. The method recited in claim 2, wherein said organo-silicone-based detergent comprises a backbone with ethylene oxide polyether polar fingers.
- 15. The method recited in claim 2, wherein said organo-silicone-based detergent comprises a backbone with ethylene oxide and propylene oxide polyether polar fingers.
- 16. A method of dry cleaning articles comprising the acts of:
- (a) immersing said articles to be dry cleaned in a composition including a siloxane solvent and an ionic organo-silicone-based detergent capable of providing the composition with hydrophilicity such that impurities removed from said articles remain in at least one of a suspended and dissolved state in the composition;
- (b) agitating said articles in said composition; and
- (c) removing said composition from said articles.
- 17. The method recited in claim 16, wherein said composition comprises a siloxane solvent selected from the group consisting of pentamer, tetramer, and hexamer cyclic siloxanes.
- 18. The method recited in claim 16, wherein said composition further comprises at least one additive selected from the group consisting of disinfectants, surfactants, suspending agents and brighteners.
- 19. The method recited in claim 16, wherein said organo-silicone-based detergent comprises a backbone with between 1 and 300 moles of polar fingers per molecule.
- 20. The method recited in claim 16, wherein said organo-silicone-based detergent comprises a backbone with polar fingers between 20% and 90% by weight.
- 21. The method recited in claim 16, wherein said organo-silicone-based detergent comprises a backbone with a hydrophilic/lipophilic balance of between 4 and 18.
- 22. The method recited in claim 16, wherein said organo-silicone-based detergent comprises a backbone with ethylene oxide polyether polar fingers.
- 23. The method recited in claim 16, wherein said organo-silicone-based detergent comprises a backbone with ethylene oxide and propylene oxide polyether polar fingers.
- 24. The method recited in claim 16, wherein said organo-silicone-based detergent comprises a backbone with linear organic polyethers of ethylene oxide as polar fingers.
- 25. The method recited in claim 19, wherein said fingers are ionic.
