Description
D-alpha tocopheryl acetate powder is a natural-source dry form of vitamin E, produced by spray-drying emulsified d-alpha tocopheryl acetate into a carbohydrate matrix.
Standardized to ≥51.5% assay and ≥700 IU/g (HPLC), it is the workhorse ingredient for food fortifiers, multivitamin tablet makers and dry-blend contract manufacturers who need a stable, free-flowing, water-dispersible vitamin E.
KEEP INGREDIENTS supplies natural vitamin E bulk powder (product code CP700) with a 36-month demonstrated stability track record, documented under both accelerated (40 °C / 75% RH) and long-term (25 °C / 60% RH) conditions.
Unlike oily tocopheryl acetate, our dry vitamin E powder disperses readily in cold water, flows well on tablet presses and mixes evenly into premixes — solving the oil-handling, segregation and content-uniformity problems that liquid vitamin E causes in dry formulations.

What Is D-Alpha Tocopheryl Acetate Powder Used For?
As a natural vitamin E supplement ingredient, our 700 IU dry powder is commonly built into:
• Multivitamin and mineral tablets and capsules
• Dry beverage premixes and stick-pack nutrition powders
• Fortified dry foods, dairy replacers and instant drinks
• Antioxidant skin and anti-aging supplement blends
• Pet nutrition and functional food fortification
The esterified acetate form is more stable to light and oxygen than free tocopherol, and the spray-dried beadlet form avoids the oil-handling issues of liquid vitamin E.
