  • Patent number: 5385737
    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 in 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.
