Abstract: The present disclosure discloses a water-in-oil type solid stick composition containing a large amount of water phase that can obtain a stable formulation while containing an acidic active ingredient, and can have a water-bursting effect immediately upon applying to the skin by containing a large amount of water phase. According to the present disclosure, the solid stick formulation can be stabilized without pH restriction, and is also excellent in terms of safety because PEG and silicone oil are not used.
