What are the best essential oils for keeping their scent in cold process soaps?

Here is the answer to your next soap making question:

There are a huge range of essential oils available on the market, I couldn't possibly comment against them all, however, they are divided into three types, or "notes" - Top notes, Middle notes and Base notes, this description is usually included either on the website description for the product, or on the label.

Generally, middle and base notes are the best at keeping their scent, the top notes include the citrus oils including orange, lemon etc. they are sharper than other fragrances and are more volatile so they disappear more quickly. By contrast, base notes include the woody and earthy scents which seem to last forever, with middle note appropriately somewhere in between.
