Polacrilin Potassium is an effective tablet disintegrant, while providing the necessary hardness and chemical stability. It swells up enormously when in contact with water or gastro-intestinal fluids causing rapid disintegration without the formation of lumps.. About 0.5 - 5 % Polacrilin Potassium can be added in dry form to the formulation
