    Abstract: To provide a method for purification of the ionic polymer compound comprising efficiently removing low-molecular impurities, for example, ionic remaining monomers, which are charged identically to the ionic polymer compound from the ionic polymer compound in a shorter period of time. A method for purification of an ionic polymer compound, characterized by removing low-molecular impurities, such as ionic remaining monomers, by the use of an ultrafiltration membrane and/or a reverse osmosis membrane from an aqueous solution containing the ionic polymer compound and low-molecular impurities which are charged identically to the ionic polymer compound, under conditions that a concentration of the ionic polymer compound is from 7 to 20% by weight, and that an amount of charges of the ionic polymer compound in the aqueous solution is 0.30 gram-equivalent/liter or more.

    Abstract: Surfactant-containing seamless capsules of the present invention have an inner layer and an outer layer having a film-forming material. The inner layer contains an oily component and a surfactant component. Such surfactant-containing seamless capsules are produced using a multiple nozzle of triple or more having a sequentially increasing diameter. Since the capsules are excellent in emulsive dispersibility of the content liquid and surfactant dispersibility and solubility in the oily component, they can be used in pharmaceuticals, foods, luxury foods, bath additives, detergents and other fields.
