  • Publication number: 20210069072
    Abstract: The instant invention relates to a composition for cosmetic raw material containing microcapsule containing one core, a first laminated coating surrounding the core having at least 45% in weight with respect to the total weight of a microcapsule of multilayered reflecting particles having at least a mixture of two metal oxides, and a second laminated coating surrounding the first layered coating, having at least 10% to 40% in weight of titanium dioxide with respect to the total weight of a microcapsule, wherein the multilayered reflecting particles are released from the at least one microcapsule only when the composition is applied onto a keratinic material, such as keratin fibers or skin. The invention further relates to a process for preparing the composition for cosmetic raw material containing microcapsule containing the same.

  • Patent number: 10813851
    Abstract: According to the present invention, provided is a core-shell structured chromic microcapsule having a size of 50-1,500 ?m, comprising: a core comprising a colorant core (A) and an optional inner color layer (B); and a shell comprising a pressure sensitive destructible wall layer (C) encompassing the core, an optional outer color layer (D) and an optional outermost protective layer (E), wherein the colorant core allows a high content of a colorant to be contained, and the pressure sensitive destructible wall layer comprises carbon dioxide particles and a binder comprising one or more wall-forming materials and one or more lipid-base materials.

  • Patent number: 10702041
    Abstract: The present invention relates to a cosmetic comprising a cosmetic composition of bead-type liquid foundation filled in a mesh net equipped cosmetic container. This cosmetic maintains portability as the conventional cushion-type cosmetic has and at the same time is more advantageous in preventing the loss of cosmetic ingredients because urethane foam is not used as a carrier for the cosmetic composition herein.

  • 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.
