Citrus Junos Fruit Extract

Citrus junos fruit extract is produced by water, hydro-alcoholic, or glycol extraction of whole Citrus junos fruit — typically the peel and pulp combined. The resulting extract contains citric acid, polyphenols (including hesperidin and naringin derivatives), limonoids, and trace amounts of essential oil components such as limonene and yuzunone.

The peel oil itself — Citrus Junos Peel Oil — is a separate, more strongly aromatic ingredient often used for fragrance functions. The fruit extract and the peel oil are distinct ingredients with distinct typical use cases.

Yuzu extract appears in face toners, essences, body washes, bath products, and hand creams. It is most strongly associated in Japan with winter seasonal products — reflecting the cultural association with the yuzu-yu bath on the winter solstice (tōji). Brands often release yuzu-themed limited editions in November and December.

The ingredient is also used in hair care and fragrance blends, where yuzu's distinct aroma anchors a specifically Japanese olfactory signature that is increasingly recognized in international perfumery.

Listed in the JSCI Japanese Cosmetic Ingredient Codex under ユズ果実エキス and permitted as a cosmetic ingredient.

As a food product, yuzu fruit and its juice are regulated under the Food Sanitation Act. Yuzu-producing regions participate in the geographical indication (GI) system for certain locally designated varieties — product and ingredient naming should reflect generic "yuzu" rather than any GI-protected regional name.
