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.
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.
