Abstract
(EN)
The present invention relates to: titania particles comprising a first region expressing an indigo or blue series color, and a second region encompassing the first region and expressing a yellow series color, wherein the color of the first region and the color of the second region are combined so as to express a red or brown series color overall; and preparation method therefor. The titania particles of the present invention has excellent absorption in a range of an ultraviolet region and of 400-800 nm, and particularly: has excellent absorption in a range of 380-495 nm, which is a blue light region that is the closest wavelength region to the ultraviolet range in the visible range and has short and strong energy, thereby promoting skin damage and aging; does not cause whitening; causes no chemical reactions on the skin even after absorption of ultraviolet rays so as to have no side effects; and mixes well with other ultraviolet-blocking ingredients.
(FR)
La présente invention concerne : des particules de dioxyde de titane comprenant une première région exprimant une couleur de la gamme indigo ou bleue, et une seconde région englobant la première région et exprimant une couleur de la gamme jaune, la couleur de la première région et la couleur de la seconde région étant combinées de façon à exprimer une couleur générale de la gamme rouge ou brun ; et sa méthode de préparation. Les particules de dioxyde de titane de la présente invention ont une excellente absorption dans une plage d'une région ultraviolette et de 400 à 800 nm, et en particulier : ont une excellente absorption dans une plage de 380 à 495 nm, qui est une région de lumière bleue qui est la région de longueur d'onde la plus proche de la plage d'ultraviolets dans la plage visible et a une énergie courte et forte, ce qui favorise les lésions cutanées et le vieillissement ; ne provoquent pas de blanchiment ; ne provoquent pas de réactions chimiques sur la peau même après absorption de rayons ultraviolets de manière à ne pas avoir d'effets secondaires ; et se mélangent bien avec d'autres ingrédients bloquant les ultraviolets.

본 발명은, 남색 또는 청색 계열의 색을 나타내는 제1 영역과, 상기 제1 영역을 감싸면서 노란색 계열의 색을 나타내는 제2 영역을 포함하며, 상기 제1 영역의 색과 상기 제2 영역의 색이 색 조합되어 전체적으로 적색 또는 갈색 계열의 색을 나타내는 것을 특징으로 하는 티타니아 입자 및 그 제조방법에 관한 것이다. 본 발명의 티타니아 입자는, 자외선 영역뿐만 아니라 400∼800 nm의 범위에서 흡수력이 우수하며, 특히 가시광선 중 자외선에 가장 가까운 파장 영역이면서 짧고 강한 에너지를 가지고 있어 피부 손상 및 노화를 촉진시킬 수 있는 블루라이트 영역인 380∼495 nm 영역에 대한 흡수력이 우수하고, 백화 현상을 일으키지 않으며, 자외선을 흡수한 후에도 피부에 화학적 반응을 일으키지 않아 부작용이 없으며, 다른 자외선 차단제 성분들과도 잘 혼합된다.
