Process for producing alpha lipoic acid / cyclodextrin complex and product produced

摘要

The invention relates to a process for the preparation of a cyclodextrin/alpha lipoic acid complex characterized in that in a first step of a two step process an alpha lipoic acid and a cyclodextrin are dissolved in an aqueous alkaline solution having a pH above pH 7, and in a second step an acid is added to lower the pH of the solution to a pH below pH 7.
