Here is something that worked for me: My very first solo soap (way back in the first of January!) was scented with tangerine and lemon eucalyptus EO. I am using the test bar now. It smells great--very citrusy. I can smell it when it is both wet and dry. The scent seemed to go away during the second, third weeks, then as it got harder and harder it came back. I am happy with it. kpduty
