Abstract
The present invention relates to an anhydrosugar alcohol composition having enhanced storage stability, and an anhydrosugar alcohol storage method, and more specifically, to an anhydrosugar alcohol composition having enhanced storage stability by comprising anhydrosugar alcohol and an amine-based additive; and to a method by which anhydrosugar alcohol having excellent quality may be provided by having the storing of the anhydrosugar alcohol performed under the existence of the amine-based additive, thereby remarkably enhancing the storage stability of the anhydrosugar alcohol.
