Abstract

To provide a formulation technique whereby, in an external composition containing allantoin and / or a derivative thereof, and urea, the decomposition of the allantoin and / or derivative thereof can be suppressed, to improve the storage stability.SOLUTION: An external composition contains allantoin and / or a derivative thereof, and urea, together with tocopherol and / or a derivative thereof. The external composition can suppress the decomposition of the allantoin and / or derivative thereof, so that the storage stability of the allantoin and / or derivative thereof is significantly improved.SELECTED DRAWING: None
