Vitamin E D-Alpha-Tocopheryl Succinate

Vitamin E D-Alpha-Tocopheryl Succinate (CAS 4345-03-3) is the esterified succinate form of natural-source d-alpha-tocopherol, widely used across food, nutraceutical, pharmaceutical, and personal care manufacturing. Its dry, free-flowing crystalline powder form makes it a preferred alternative to oil-based tocopherols where moisture sensitivity, handling convenience, or precise dosing are operational priorities. As a stable ester, d-alpha-tocopheryl succinate resists oxidation during processing and storage far more effectively than free tocopherol. It is recognised as an antioxidant and stabiliser in finished formulations, and supports authorised EU health claims under Regulation (EC) No 432/2012 — specifically that vitamin E contributes to the normal protection of cells from oxidative stress.

In food supplements and nutraceutical applications, it is listed as D-alpha-tocopheryl acid succinate in Annex II of Directive 2002/46/EC and in Annex II of Regulation (EC) No 1925/2006 covering food fortification, confirming its regulatory acceptance across the EU market. Potency is typically expressed in IU or alpha-tocopherol equivalents; commercially available specifications commonly run at 1185 IU/g or 1210 IU/g, with 1 mg d-alpha-tocopherol equivalent to 1.49 IU for reference calculations. For pharmaceutical manufacturers, the material is available in grades meeting USP and Ph. Eur. monograph requirements, supporting inclusion in solid oral dosage forms such as capsules and tablets where compatibility with excipients and low moisture content are critical. Its non-hygroscopic character simplifies direct compression and blending operations.

In personal care and cosmetic formulations, tocopheryl succinate functions as a skin-conditioning antioxidant and formulation stabiliser in serums, creams, and topical treatments. Its powder form integrates readily into anhydrous and emulsion systems, offering formulators flexibility that oil-based vitamin E sources do not always provide. Food-grade supply is classified under HS code 2936.28 (vitamin E and its derivatives), and the material is suitable for use in fortified foods and functional beverages where regulatory traceability across the supply chain is required. Documentation including certificates of analysis, MSDS, and origin declarations is available to support compliance workflows.
