Claims23
A composition for cleaning and degreasing, the composition consisting essentially of a 2-ethylhexy ester and one or more components selected from the group consisting of a diluent, a surfactant, and a co-solvent.
A composition for cleaning and recycling comprising:
- about 0.5 to about 2 weight percent co-solvent;
- and
- about 70 to about 99.5 weight percent 2-ethylhexyl ester.
A composition for cleaning and recycling comprising:
- about 5 to about 30 weight percent surfactant;
- and
- about 70 to about 90 weight percent 2-ethylhexyl ester.
A composition for cleaning and recycling comprising:
- about 0 to about 50 weight percent diluent;
- about 1 to 50 weight percent surfactant;
- about 1 to about 20 co-solvent;
- and
- about 10 to about 99 weight percent 2-ethylhexyl ester.
A method of cleaning a substrate, the method comprising the steps of:
- proving a cleaning solution comprising a 2-ethylhexyl ester;
- and
- applying the cleaning solution to a substrate.
A system for recycling a cleaning solution, the system comprising:
- a cleaning solution comprising 2-ethylhexyl ester;
- and
- a chamber configured to receive the cleaning solution mixed with waste and a pressurized gas.
A method of recycling a cleaning solution, the method comprising the steps of:
- providing a 2-ethylhexyl ester solution;
- applying the 2-ethylhexyl ester solution to a substrate to create a mixture of 2-ethylhexyl ester and waste;
- supplying the mixture to a pressure chamber;
- adding pressurized gas to the mixture in the pressure chamber;
- removing the waste;
- and
- depressurizing a combination of 2-ethylhexyl ester and gas.
