What it is and how it behaves in soap

Bergamot oil is pressed from the peel of the bergamot orange, Citrus bergamia, and more than nine-tenths of it comes from Calabria in southern Italy. It smells of sweet citrus with a floral, slightly woody edge.

In cold process soap it fades like other peel oils, but it does not noticeably speed trace and it helps other citrus scents stick (Grosso). Faiola pairs it with litsea at 2 to 4 % of the oils, and Cable uses 0.7 to 1.4 %. The IFRA figure on this page is the ceiling.

Pressed bergamot contains bergapten, which can mark skin left in the sun. IFRA restricts it in leave-on products but, so far, not in rinse-off soap; its 52nd Amendment, due in 2027, revisits these oils, and a furocoumarin-free (FCF) grade avoids the question. Ten of eleven bergamot oils bought online failed the ISO standard (Pierson and colleagues), so buy from a supplier who tests.
