Zusammenfassung:	The present invention relates to a method for evaluation of an infrared ray blocking effect of cosmetics, comprising: measuring respective spectral reflectance before and after application of cosmetics to a skin or skin substitute using an NIR spectrophotometer; and then measuring a degree of increase in spectral reflectance after application of cosmetics, compared to the spectral reflectance before application of cosmetics. According to the present invention, it is possible to perform an objective comparison and analysis of infrared ray blocking products, and to derive a maximal infrared ray blocking ability of an infrared ray blocking product during the product development stage. La présente invention concerne un procédé pour l'évaluation d'un effet de blocage de rayons infrarouges de produits cosmétiques, consistant : à mesurer la réflectance spectrale respective avant et après l'application de produits cosmétiques sur une peau ou un substitut de peau à l'aide d'un spectrophotomètre en proche infrarouge (NIR); puis à mesurer un degré d'augmentation de la réflectance spectrale après l'application de produits cosmétiques, par rapport à la réflectance spectrale avant l'application de produits cosmétiques. Selon la présente invention, il est possible de réaliser une comparaison et une analyse objectives de produits de blocage des rayons infrarouges, et de dériver une capacité de blocage de rayons infrarouges maximale d'un produit de blocage des rayons infrarouges pendant le stade de développement du produit. 본 발명은 NIR 분광광도계를 이용하여 피부 또는 피부 대체물에 화장품을 도포하기 전과 도포한 후의 분광반사율을 각각 측정한 후, 화장품을 도포하기 전의 분광반사율에 비해 화장품을 도포한 후의 분광반사율이 증가한 정도를 평가하는 화장품의 적외선 차단 효과 평가 방법에 관한 것이다. 본 발명에 따르면, 적외선 차단 제품 간의 객관적인 비교, 분석이 가능할 뿐만 아니라 제품 개발 단계에서 적외선 차단 제품의 최대 적외선 차단 능력을 이끌어 낼 수 있다.
