Patent number: 11020335Abstract: The present invention relates to a novel coloring material including a polyamide powder and/or a polyurethane powder and a water-soluble dye. The coloring material of the present invention allows a water-soluble dye to be used in anhydrous formulations. Thereby, the range of use of dyes may be widened, reflectance may be excellent, and fluorescence properties may be obtained. Accordingly, the present invention may broaden the spectrum of cosmetic coloring materials used in limited applications in the cosmetic field.Type: GrantFiled: October 15, 2018Date of Patent: June 1, 2021Assignee: LG HOUSEHOLD & HEALTH CARE LTD.Inventors: Hong Ha Son, Kyong Seob Kim, Khee Hwan Choi, Ko Eun Park

Patent number: 10808060Abstract: The present application relates to a polymer and a use thereof. The present application may provide a functional polymer which expresses a low solubility to a polar solvent and a non-polar solvent and which is suitable for forming a film. If applied to the use of cosmetics such as mascara or to medical uses, the polymer in the present application may express a tolerance to diverse solvents such as sebum, sweat, tears and the like, and thus enables makeup to last, etc. Accordingly, the polymer may be applied to diverse uses and used in film forming agents, cosmetic compositions, or cosmetics, or the like.Type: GrantFiled: December 15, 2015Date of Patent: October 20, 2020Assignee: LG Chem, Ltd.Inventors: Su Jeong Kim, Jeong Ae Yoon, Sung Soo Yoon, Kyong Seob Kim, Khee Hwan Choi, Hae Seok Chae
