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 a chemical selected from the group consisting of 2-ethylhexyl acetate, dibasic esters, glycol ether DPM acetate, glycol ether acetate, 2-ethylhexyl alcohol, cyclohexanol, hexanol, glycol ether PTB, glycol ether DPTB, and glycol ether DPNP;
- (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 chemical includes 2-ethylhexyl acetate.
- 4. The method recited in claim 3, wherein said siloxane solvent includes tetramer cyclic siloxane.
- 5. The method recited in claim 4, wherein based on the weight of the composition said tetramer cyclic siloxane is 75% by weight and said 2-ethylhexyl acetate is 25% by weight.
- 6. The method recited in claim 3, wherein said siloxane solvent includes pentamer cyclic siloxane.
- 7. The method recited in claim 6, wherein based on the weight of the composition said pentamer cyclic siloxane is between 60% and 80% by weight and said 2-ethylhexyl acetate is 20% and 40% by weight.
- 8. The method recited in claim 6, wherein based on the weight of the composition said pentamer cyclic siloxane is 50% by weight and said 2-ethylhexyl acetate is 50% by weight.
- 9. The method recited in claim 6, wherein based on the weight of the composition said pentamer cyclic siloxane is 15% by weight and said 2-ethylhexyl acetate is 85% by weight.
- 10. The method recited in claim 3, wherein said siloxane solvent includes pentamer cyclic siloxane and tetramer cyclic siloxane.
- 11. The method recited in claim 10, wherein based on the weight of the composition said tetramer cyclic siloxane is 15% by weight, said pentamer cyclic siloxane is 55% by weight and said 2-ethylhexyl acetate is 30% by weight.
- 12. The method recited in claim 1, wherein said chemical is selected from the group consisting of dibasic esters, glycol ether DPM acetate, and clycol ether acetate.
- 13. The method recited in claim 1, wherein said chemical is selected from the group consisting of 2-ethylhexyl alcohol, cyclohexanol, and hexanol.
- 14. The method recited in claim 1, wherein said chemical is selected from the group consisting of glycol ether PTB, glycol ether DPTB, and glycol ether DPNP.
