After drying the extract, IR measurement was performed, and it was confirmed that the main component of the extract was silicone oil. IR measurements are measurements by infrared spectroscopy, and the ATR method was used this time. From this, the amount of the extract containing silicone oil as a main component attached to each sample was calculated.
