Abstract
The present invention aims to provide a particulate composition containing anhydrous crystalline 2-O-α-D-glucosyl-L-ascorbic acid having a significantly, hardly solidifiable property compared to conventional ones in a grade for use in quasi-drugs; a process for producing the same; and uses thereof. The present invention solves the above object by providing a particulate composition containing anhydrous crystalline 2-O-α-D-glucosyl-L-ascorbic in an amount of over 98.0% by weight but less than 99.9% by weight, on a dry solid basis; or a degree of crystallinity of 90% or higher for anhydrous crystalline 2-O-α-D-glucosyl-L-ascorbic acid; and by providing a process for producing the same and uses thereof.
