Publication number: 20220287938Abstract: The present invention relates to a cosmetic composition comprising a eutectic mixture containing: an amino acid, an alpha-hydroxy acid, and water; or two types of amino acids. The cosmetic comprises either an amino acid and an alpha-hydroxy acid or two types of amino acids in the form of a eutectic mixture. Thus, a cosmetic composition with excellent skin penetration effect even under weakly acidic or neutral pH conditions, which causes less irritation, can be provided, wherein the cosmetic composition provides excellent keratin exfoliation, reduces the number of pores, enhances skin elasticity, and promotes skin regeneration while having excellent low-temperature stability.Type: ApplicationFiled: August 21, 2020Publication date: September 15, 2022Applicant: LG HOUSEHOLD & HEALTH CARE LTD.Inventors: Koo Chul KWON, Tae Geun KWON, Sang Wook PARK, So Young LEE, Ji Hyun SEO

Publication number: 20220257803Abstract: The present invention relates to a superparamagnetic gold nanoparticle cluster-protein nanoparticle fusion body for magnetic resonance imaging and magnetic thermotherapy. According to the present invention, a superparamagnetic gold nanoparticle cluster-protein nanoparticle fusion body which has target directionality and a high density of ultrafine gold nanoparticles uniformly coupled to the surface of protein nanoparticles can be fabricated with neither a separate surface stabilization process nor a separate target directionality conferring process. Hence, the superparamagnetic gold nanoparticle cluster-protein nanoparticle fusion body according to the present invention is superior to conventional gold nanoparticles in terms of biocompatibility and has excellent target directionality as well as being identified to have a temperature elevation potential in an alternating magnetic field and a functionality as a T2-MRI contrast medium thanks to the superparamagnetism property of the ultrafine gold nanoparticles.Type: ApplicationFiled: April 18, 2022Publication date: August 18, 2022Applicant: CELLEMEDY INC.Inventors: Jeewon LEE, Koo Chul KWON, Eunji JO
