Abstract
A process is described for making high density tocopherol succinate powder. In this process, a solution of tocopherol succinate is prepared in hexane. The hexane is removed under heat and pressure. The resulting powder is then mixed with hexane yielding larger particles and a denser product. In the process, an atmosphere enriched in nitrogen is maintained over said tocopherol powder during said process.
