What it is and how it behaves in soap

Black pepper oil is steam-distilled from the dried, unripe fruit of the pepper vine, Piper nigrum (ISO 3061), and the spice itself comes mostly from Vietnam, India, Brazil and Indonesia (FAO). It smells dry, woody and warm, like freshly ground pepper, from caryophyllene, limonene and pinene.

Faiola lists black pepper among the essential oils that behave well in cold process soap. Her recipes pair it with redistilled orange or lemongrass, or use it alone, at 1.5 to 4 % of the oils, and Grosso describes its scent as sweet, peppery and woody. It gives citrus and lavender blends weight without sweetness.

IFRA's annex gives no figure for black pepper oil, so the ceiling is your supplier's certificate. Limonene and pinene oxidise in air into stronger skin sensitisers (SCCS), so buy small amounts and keep the bottle cool, full and closed.
