Summary:The present invention relates to a manufacturing method for a 3-ingredient cocrystal including kojic acid, tranexamic acid, and nicotinamide. According to the present invention, the manufacturing method for a 3-ingredient cocrystal manufactures a 3-ingredient cocrystal after initially manufacturing a 2-ingredient cocrystal. The 3-ingredient cocrystal shows the most stable solid when a mole fraction of three ingredients in the 3-ingredient cocrystal generated as a result is the tranexamic acid: the nicotinamide: and the kojic acid = 1:1:1 regardless of the mixing ratio of the tranexamic acid, the nicotinamide, and the kojic acid used in the reaction. According to the present invention, the 3-ingredient cocrystal manufactured by the same can be applied in various cosmetic compositions by maintaining physicochemical stability in a case that the 3-ingredient cocrystal manufactured by the same is used in a solid cosmetic composition or a liquid cosmetic composition. 본 발명은 코직산, 트라넥삼산 및 니코틴아미드를 포함하는 3성분 코크리스탈의 제조방법에 관한 것이다. 본 발명의 방법은 2성분 코크리스탈을 먼저 제조한 후, 이어 3성분 코크리스탈을 제조하는 것을 특징으로 하며, 반응시 사용된 트라넥삼산, 니코틴아미드의 코직산의 배합 비율과 상관없이, 결과적으로 생성된 3성분 코크리스탈에서 3성분의 몰비가 트라넥삼산:니코틴아미드:코직산 = 1:1:1 인 경우 가장 안정한 고체형을 나타내었다. 본 발명의 방법에 의해 제조된 3성분 코크리스탈은 고상 또는 액상 화장료 조성물에 사용되는 경우 물리화학적 안정성을 유지할 수 있어 다양한 화장료 조성물에 적용될 수 있다는 장점이 있다.
