The present invention relates to skin whitening cosmetics containing compounds having melanogenesis inhibiting activities. A skin whitening composition according to the present invention comprises, as an active ingredient, a material selected from the group consisting of phloroglucinol (CAS RN. 108-73-6), isoliquiritigenin (CAS RN. 961-29-5), 4&prime,5,7-Trihydroxyflavanone (CAS RN. 480-41-1), 3,5-dihydroxybenzyl alcohol (CAS RN. 29654-55-5), pinobanksin (CAS RN. 548-82-3), taxifolin (CAS RN. 480-18-2), eriodictyol (CAS RN. 4049-38-1), phloroglucide (CAS RN. 491-45-2), 5,7-dihydroxyflavanone (CAS RN. 480-39-7), and mixtures thereof. Compounds according to the present invention have excellent pigmentation inhibiting effects by inhibiting melanogenesis. Therefore, compositions such as cosmetics containing the compounds as active ingredients can be used very effectively in skin whitening such as improvements in chloasma and freckles.COPYRIGHT KIPO 2016본 발명은 멜라닌 생성 억제 활성을 갖는 화합물을 함유하는 피부미백용 화장료에 관한 것으로서, 본 발명에 따른 피부미백용 화장료는 플로로글루시놀(Phloroglucinol, CAS RN. 108-73-6), 이소리퀴리티게닌(Isoliquiritigenin, CAS RN. 961-29-5), 4,5,7-트리하이드록시플라바논(4,5,7-trihydroxyflavanone, CAS RN. 480-41-1), 3,5-디히드록시벤질알콜(3,5-dihydroxybenzyl alcohol, CAS RN. 29654-55-5), 피노반크신(Pinobanksin, CAS RN. 548-82-3), 탁시폴린(Taxifolin, CAS RN. 480-18-2), 에리오딕티올(Eriodictyol, CAS RN. 4049-38-1), 플로로글루시드(Phloroglucide, CAS RN. 491-45-2), 5,7-디하이드록시플라바논(5,7-dihydroxy flavanone, CAS RN. 480-39-7) 및 이들의 혼합물로 이루어진 군으로부터 선택된 어느 하나를 유효성분으로 함유하는 것을 특징으로 한다. 본 발명에 따른 화합물들은 멜라닌 생성을 억제하여 색소 침착 저해효과가 뛰어나므로, 이들 화합물들을 유효성분으로 함유하는 화장료 등의 조성물은 기미나 주근깨 개선 등의 피부 미백에 매우 효과적으로 사용될 수 있다.
