Abstract
A process of producing a tocopheryl succinate powder is provided. The process forming a tocopheryl succinate powder into a plastic mass. The plastic mass is then allowed to cool whereupon its sets to a solid state. The solid mass can then be subjected to a size reduction to obtain a tocopherol succinate powder having a desirable particle size, e.g. not more than 5% by weight through a 120-mesh sieve and not more than 5% by weight retained on a 14-mesh sieve.
Claims18
A process for increasing the particle size of a powder comprising tocopheryl succinate without binders, which comprises the steps of:
- heating a mass of tocopheryl succinate powder to an elevated temperature effective to form a plastic, but not melted, mass of tocopheryl succinate;
- extruding said mass into at least one elongated form;
- allowing said elongated form to cool for an effective period of time to set to a solid form;
- and
- reducing the particle size of said solid form.
