The present invention relates to: an oil-in-water (O/W) liquid crystal emulsion cosmetic composition including a water-dispersible emulsifier and a higher alcohol; and a method for producing same. By producing a liquid crystal emulsion by dispersing a water-dispersible emulsifier in an aqueous phase portion and dissolving a small amount of higher alcohol in an oily phase portion, the content of the oily phase portion can be minimized, unlike existing liquid crystal emulsions in which a large amount of the oily phase portion is present, and an oil-in-water (O/W) emulsion cosmetic composition that moisturizes without feeling heavy and oily can be produced by minimizing the content of the oil phase portion. La présente invention concerne : une composition cosmétique en émulsion de cristaux liquides de type huile dans l'eau (H/E) comprenant un émulsifiant hydrodispersible et un alcool d'ordre supérieur ; et un procédé de production associé. Grâce à la production d'une émulsion de cristaux liquides par dispersion d'un émulsifiant hydrodispersible dans une partie phase aqueuse et dissolution d'une petite quantité d'un alcool d'ordre supérieur dans une partie phase huileuse, il est possible de minimiser la teneur en la partie phase huileuse, au contraire des émulsions existantes de cristaux liquides, dans lesquelles une grande quantité de la partie phase huileuse est présente, et une composition cosmétique en émulsion de type huile dans l'eau (H/E) qui humidifie sans donner une sensation lourde et huileuse peut être préparée par minimisation de la teneur en la partie phase huileuse. 본 발명은 수분산 유화제 및 고급 알코올을 포함하는 수중유형 (O/W) 액정 에멀젼 화장료 조성물 및 이의 제조 방법에 관한 것으로, 수분산이 가능한 유화제를 수상부에 분산하고, 소량의 고급 알코올을 유상부에 용해하여 액정 에멀젼을 제조함으로써, 다량의 유상부가 존재하였던 기존의 액정 에멀젼과 달리 유상부의 함량을 최소화 할 수 있으며, 유상부 함량의 최소화로 무겁고 오일리한 사용감 없이 사용 후 촉촉한 수분감이 느껴지는 수중유형 (O/W) 에멀젼 화장료 조성물을 구현할 수 있다.
