Tsubaki / Camellia Oil

Supplier-disclosed industry ranges are typically 5–20 kg for cosmetic-grade Camellia japonica seed oil with 4–8 week lead times. Harvest is concentrated in October–December and small-island production (Izu Oshima, Goto) has tight annual capacity, so allocation is generally to standing accounts. Refined and unrefined grades are usually quoted separately.

Not directly. Cold-pressed (unrefined) tsubaki oil retains a faint nutty aroma and slight color, suited to natural-positioning hair and face oils where the heritage story is part of the claim. Refined grades have a near-neutral aroma and lighter color and are used in formulations where the oil is one component of a complex blend or where fragrance neutrality matters. Oxidative stability is broadly similar due to the high oleic content; tocopherol fortification is common in finished products.

Specific producers issue origin certificates declaring island-of-harvest, with Izu Oshima (operated by long-established refiners since the early 20th century) and the Goto Islands in Nagasaki being the two best-documented single-origin sources. Buyers seeking heritage-positioning material should request origin documentation at RFQ; expect smaller MOQ ceilings and longer allocation queues for verified single-island lots.
