Summary:The present invention relates to a colored pearlescent pigment, and more specifically, to a pearlescent pigment; to a manufacturing method thereof; and to a cosmetic composition containing the pearlescent pigment as an active ingredient, wherein the pearlescent pigment has red, violet, blue and green colors due to an optical color effect by treating the surface of a simple pearlescent pigment with ferric oxide and partially converting the ferric oxide (Fe_2O_3) into ferrous ferric oxide (Fe_3O_4) via a reduction firing method. According to the present invention, the colored pearlescent pigment can exhibit the same color and gloss as red, violet, blue and green pearlescent pigments obtained by treating surfaces of the pearlescent pigments with ordinary carmine dye, ferrocyan blue dye, etc. Also, the colored pearlescent pigment can overcome problems which can occur under various conditions of a cosmetic formulation, such as change in color formation, color breakup (bleeding), color permeation in a formulation, etc. which appear due to pH conditions and interaction between raw materials. Accordingly, the colored pearlescent pigment can be practically used as a substitute for an existing pearlescent pigment. In addition, the colored pearlescent pigment comprises only stable inorganic materials and thus can be formed freely from various regulation as a natural or synthetic chemical color is not required. 본 발명은 유색 진주 광택 안료에 관한 것으로, 더욱 상세하게는 단순한 진주 광택 안료에 표면에 페릭옥사이드를 표면 처리한 후, 환원 소성 기법을 이용하여 페릭옥사이드(FeO)를 일부 페러스페릭옥사이드(FeO)로 변형시켜 광학적인 색상 효과에 의해 적색, 보라, 청색, 녹색의 외관 색상을 갖는 진주 광택 안료, 이의 제조 방법 및 이를 유효성분으로 함유하는 화장료 조성물에 관한 것이다. 본 발명에 따른 유색 진주 광택 안료는 일반적인 카민, 페로시안블루 등을 표면 처리하여 얻어지는 적색, 보라색, 청색, 녹색의 진주 광택 안료와 같은 색상 및 광택성을 표현할 수 있고, 다양한 화장품 제형의 환경에서 나타날 수 있는 pH 조건 및 원료들의 상호 작용으로 나타나는 발색의 변화 또는 색상 분리 현상(블리딩) 또는 제형에서의 번짐 등의 문제점을 극복 할 수 있어, 기존 진주 광택 안료를 대체하여 유용하게 사용할 수 있다. 또한 안정한 무기 재료로만 구성되어 있으므로, 천연 또는 합성 화학 색소를 배제시킬 수 있어, 다양한 규제에서 자유로운 처방구성이 가능할 것이다.
