Abstract

Способ получения кристаллического пантотената кальция, который включает стадию поглощения влаги гомогенной смесью, содержащей кристаллический пантотенат кальция и аморфный пантотенат кальция. Вышеуказанный способ включает, например, следующие стадии: (1) смешивание кристаллического пантотената кальция и аморфного пантотената кальция до получения гомогенной смеси и (2) поглощение влаги гомогенной смесью, полученной на вышеуказанной стадии (1), что обеспечивает эффективное получение кристаллического пантотената кальция с чрезвычайно низкой гигроскопичностью.Международная заявка была опубликована вместе с отчетом о международном поиске.
