Buyer Decision Guide
Vitamin grades are specified by potency, carrier and purity, and the same vitamin name can cover several physical forms. Confirm the exact form and the analytical method before comparing quotations; overage and stability requirements are project-specific.
- Confirm the exact physical form and carrier
- Check declared potency and the assay method
- Review stability and overage needs for your format
- Confirm light, heat and oxygen sensitivity in handling
How This Grade Differs
DL-alpha-Tocopherol must be compared on physical form, carrier and declared potency rather than on the vitamin name alone. Powder, oil, crystal and diluted forms behave differently in blending, dosing and shelf life.
Compare these related grades before approval:
For a substitution review, compare DL-alpha-tocopherol identity, the 98.0%-101.0% HPLC assay, viscous oil form and the current offered-batch COA. This oil is a different purchasing specification from vitamin E acetate powder.
Application Areas
Discuss the intended formulation and processing conditions with the supplier before selecting this oil ingredient.
Packaging and Delivery
