| Outline of Final Research Achievements |
To develop dry-cleaning technique using water/supercritical CO2 dispersions for space station, this study prepared the high-pressure apparatus, developed a CO2-philic solubilizer, and explored effective additives and experimental condition for the dry-cleaning. Dry cleaning using water/CO2 dispersions with very small amounts of those additives (1mM custom-made solubilizer, 10mM water, and 5 mg protease) successfully increased the washing efficiencies for protein from 0% to 28% and for total soils contained in the washing object from 67% to 85 %.
