  • Publication number: 20210299008
    Abstract: Nanocapsules that form emulsion particles and an emulsion composition including the nanocapsules are disclosed. The emulsion composition contains an aqueous phase; an oil phase; and emulsion particles surrounded by a plurality of non-amphiphilic nanocapsules located in the interface between the aqueous phase and the oil phase. The emulsion composition is capable of forming emulsion particles in an oil-in-water-type emulsion composition, without using a surfactant.

  • Patent number: 8505556
    Abstract: A tapping applicator comprises a stationary part, a vibrating part, a vibrating plate, a puff, a power supply, and a control part. The stationary part consists of a casing, an insulating spool provided on the bottom of the casing, and a coil which winds around the insulating spool. The vibrating part consists of a magnet inserted to move up and down along a hollow of the insulating spool. The vibrating plate is integrated into the magnet in the top of the magnet. The puff is vibrated by vibrations of the vibrating plate. The power supply supplies an alternating current power source to the coil. The control part controls the vibration-generating module.
