The unsaturated branch of the vitamin E family. Worldbestve supplies palm and rice-bran tocotrienol concentrates in oil and powder form — with the total tocotrienols assay stated separately from the grade name, so you know exactly what you are buying.
Isomer CAS: 1721-51-3 (α) · 490-23-3 (β) · 14101-61-2 (γ) · 25612-59-3 (δ) | Amber oil or white to off-white powder
The single most common sourcing error in this category.
A tocotrienol grade advertised as "50%" or "80%" almost never contains that percentage of tocotrienols. In common industry practice the headline number describes total tocols — tocotrienols plus tocopherols. The tocotrienol fraction, the part you are actually paying for, is materially lower.
This matters commercially. If you dose a formulation against the grade name rather than the true tocotrienol assay, you will under-deliver the active and fail your own label claim. It also makes quotations impossible to compare: two "80%" offers can differ by a factor of two in real tocotrienol content.
Worldbestve therefore publishes both numbers on every grade. Where a grade is named "TT-Oil 80% (Palm)", the guaranteed total tocotrienols assay is ≥ 32%. That figure, not the grade name, is what appears on the specification and the Certificate of Analysis.
Grade name, guaranteed total tocotrienols assay, form and packaging.
| Grade | Source | Form | Total Tocotrienols Assay | Packaging |
|---|---|---|---|---|
| TT-Oil 80% (Palm) | Palm oil | Amber oil | ≥ 32% | 1 / 20 kg Al bottle; steel drum |
| TT-Oil 50% (Rice-Bran) | Rice-bran oil | Amber oil | ≥ 20% | 1 / 20 kg Al bottle; steel drum |
| TT-Powder 20% (Palm) | Palm oil | White / off-white free-flowing powder | ≥ 14% | 1 / 20 kg foil bag; fiber drum |
A tocotrienol concentrate is a mixture — no single CAS number describes the finished product.
| Isomer | CAS Number | Molecular Formula | Notes |
|---|---|---|---|
| α-Tocotrienol | 1721-51-3 | C29H44O2 | Most prominent vitamin E activity of the tocotrienols |
| β-Tocotrienol | 490-23-3 | C28H42O2 | Minor component in most natural sources |
| γ-Tocotrienol | 14101-61-2 | C28H42O2 | Major component of palm-sourced concentrate |
| δ-Tocotrienol | 25612-59-3 | C27H40O2 | Notable antioxidant activity of the group |
Tocotrienols differ from tocopherols by an unsaturated isoprenoid side chain with three double bonds. That shorter, more flexible tail is why tocotrienols distribute into lipid membranes more readily and recycle faster as antioxidants than the corresponding tocopherols.
| Consideration | Palm Sourced | Rice-Bran Sourced |
|---|---|---|
| Achievable concentration | Higher (oil ≥ 32% total tocotrienols) | Moderate (oil ≥ 20% total tocotrienols) |
| Dominant isomers | γ- and δ-tocotrienol rich | Different distribution; more α present |
| Typical use | High-potency softgels, cardio & healthy-aging positioning | Rice-origin label claims, blended formulations |
| Dry form available | Yes — 20% powder (≥ 14% total tocotrienols) | Oil only |
| Application | Recommended Grade | Notes |
|---|---|---|
| High-potency supplement softgels | TT-Oil 80% (Palm) | Dose against the ≥ 32% tocotrienol assay, not the grade name |
| Tablets, capsules, dry sachets | TT-Powder 20% (Palm) | Free-flowing; avoids oil-loading and flow problems |
| Cosmetics & skincare | TT-Oil 80% or 50% | Membrane-penetrating antioxidant for lipid phases |
| Functional foods & oil blends | TT-Oil 50% (Rice-Bran) | Blends readily into edible oil systems |
| Rice-origin label claims | TT-Oil 50% (Rice-Bran) | Origin documented on specification |

Usually not. The headline percentage normally refers to total tocols — tocotrienols plus tocopherols combined — so the tocotrienol fraction itself is lower. Worldbestve states both figures: palm TT-Oil 80% carries a guaranteed total tocotrienols assay of ≥ 32%, and rice-bran TT-Oil 50% of ≥ 20%. Always ask for the assay and the isomer breakdown, not just the grade name.
Palm-sourced concentrate is typically richer in γ- and δ-tocotrienol and reaches a higher concentration, which suits high-potency softgels. Rice-bran material has a different isomer distribution and is often chosen for label reasons or where a rice-derived origin is preferred. Worldbestve supplies both.
α-tocotrienol is CAS 1721-51-3, β-tocotrienol is CAS 490-23-3, γ-tocotrienol is CAS 14101-61-2, and δ-tocotrienol is CAS 25612-59-3. Because a concentrate is a mixture of these, a single CAS number cannot describe the finished product — the COA should report each isomer.
Choose the oil for softgels, oil blends, and cosmetic lipid phases. Choose the 20% palm powder (total tocotrienols ≥ 14%) for tablets, capsules, sachets, and dry blends where adding oil would harm flow or compressibility.
Technical data sheet, batch COA with isomer breakdown, specification sheet stating the assay basis, allergen and GMO statements, heavy-metals and PAHs report, FSSC 22000 / ISO 22000 certificate, and Kosher / Halal certificates where required.
