Eosin Y used to formulate Eosin Y aqueous is in the form of the disodium salt. The free acid has very limited solubility in water, generally around 0.08%. The free acid is sometimes referred to as spirit-soluble, as the dye has somewhat higher solubilities in alcohol or alcohol.

Ischemic stroke is caused by a thromboembolic occlusion of cerebral arteries. Treatment is focused on fast and efficient removal of the occluding thrombus, either via intravenous thrombolysis or via endovascular thrombectomy.
