POLYVINYLPYRROLIDONE POWDER COMPOSITION AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a high-quality polyvinylpyrrolidone powder composition having a high dissolution rate in water even in the case of the powder composition comprising a polyvinylpyrrolidone having a high K value and to provide a method for simply producing the powder composition. SOLUTION: The polyvinylpyrrolidone powder composition comprises the polyvinylpyrrolidone having≥60 to≤130 K value and a secondary amine or a salt thereof. The polyvinylpyrrolidone powder composition is produced by adding the secondary amine or salt thereof to the polyvinylpyrrolidone having≥60 to≤130 K value or heating and drying an aqueous solution containing the polyvinylpyrrolidone having≥60 to≤130 K value and the secondary amine or the salt thereof.
