A compounding ingredient for basic cosmetics is provided to be easily absorbed transcutaneously due to comprising a decomposition product of nucleoprotein, DNA or RNA with relatively low molecular weight, thereby capable of activating cells and promoting blood circulation. And basic cosmetics comprising the same are provided to excellently prevent skin roughness, chloasma, freckles, and wrinkles and have skin whitening effect. A compounding ingredient for basic cosmetics comprises a decomposition product including 20-50% of a fraction having a molecular weight of 1,000-3,000 obtained by treating nucleoprotein and/or DNA with enzyme or hydrolyzing the nucleoprotein and/or DNA, or deoxyoligonucleotide, deoxymononucleotide or oligopeptide isolated therefrom； or a decomposition product including 20-50% of a fraction having a molecular weight of 1,000-3,000 obtained by treating RNA with enzyme or hydrolyzing it, or oligonucleotide or mononucleotide isolated therefrom； or a mixture of at least two selected from the group consisting of the decomposition product of the nucleoprotein and/or the DNA, the decomposition product of the RNA, deoxyoligonucleotide, deoxymononucleotide, oligopeptide, oligonucleotide and mononucleotide, wherein the nucleoprotein or the DNA is obtained from milt of fishes such as salmon, trout, herring, oceanic bonito and codfish and the RNA is obtained from yeast such as beer yeast, torula yeast, breast milk yeast and bread yeast. The basic cosmetics comprise the compounding ingredient for basic cosmetics.본 발명은 기초화장품용 배합제 및 기초화장품을 제공한다.본 발명은 뉴클레오프로테인 및/또는 DNA 또는 RNA의 효소 또는 가수분해생성물, 상기 분해생성물로부터 분리된 디옥시올리고뉴클레오티드, 디옥시모노뉴클레오티드, 올리고펩티드, 올리고뉴클레오티드, 모노뉴클레오티드, 또는 상기 분해생성물 또는 화합물로부터 선택된 적어도 2종의 혼합물을 유효성분으로 함유하는 기초화장품용 배합제 및 상기 배합제를 함유하는 기초화장품이다. 디옥시올리고뉴클레오티드 등과 같은 유효성분은 분자량이 비교적 작기 때문에 경피적으로 흡수되기 쉽고, 또한 그들은 경피적으로 흡수되었을 때 세포 활성화 작용 및 혈액순환 촉진 작용을 갖기 때문에, 안면의 표피에 적용시킬 경우, 피부 거침, 기미, 주근깨, 주름 등을 방지하는 효과 및 피부 미백 효과가 우수하다.
