  • Patent number: 10080709
    Abstract: The present invention relates to a method for manufacturing solid round emulsion beads by dropping liquid emulsion into a cryogenic freezing refrigerant. The obtained solid round emulsion beads can be stored and used at a low temperature. The solid round emulsion beads can be coated with a solution containing a composition which is solid at room temperature or which can form gel. The emulsion beads can be prepared by using liquid emulsion containing additional composition, which is solid at room temperature or can form gel, in the water phase of oil-in-water (O/W) emulsion or the oil phase of oil-in-water (W/O) emulsion. The emulsion beads prepared by the present invention can maintain its shape without swelling and/or damage but with stability and does not give any grainy feeling when the liquid emulsion was applied on the skin.

  • Publication number: 20180071177
    Abstract: The present invention provides a color-changing microcapsule composed of a core comprising an inner color layer having a color, a pressure-breakable wall layer surrounding the core, an optional outer color layer and an optional outermost layer, characterized in that said core comprises a core-seed and at least one inner color layer comprising a colorant and a binder, and said pressure-breakable wall layer comprises titanium dioxide particles and a binder. Said color-changing microcapsule has a high durability during storage and handling and a high masking ability of inner color, can be easily ruptured by pressing, rubbing, wiping and/or scrubbing with hand or an implement such as cloths, sponge or paper to reveal or develop the color on the inner color layer as well as can maintain the stability for a long time when incorporated into a carrier of cosmetic formulations.

  • Patent number: 7167990
    Abstract: An interfacing circuit for reducing current consumption includes a command decoder, an operation controller, and a transmission controller. The command decoder decodes input packet commands and generates corresponding commands. The operation controller generates first through N-th operation signals for performing operations corresponding to the commands in response to a clock signal. The transmission controller transmits the first through N-th operation signals as first through N-th control signals in response to the clock signal. The transmission controller comprises a reset signal generator which generates a reset signal for interrupting the transmission of the first control signal when multiple commands of the first through N-th commands are generated simultaneously, wherein the commands would otherwise incorrectly operate the circuit receiving the first through N-th control signals when the commands are generated simultaneously.
