Full Answer

For example, Hurricaine topical anesthetic, a liquid preparation of benzocaine, is 20 percent benzocaine dissolved in polyethylene glycol 400, an inert solvent. Other liquid preparations of benzocaine use ethyl alcohol or a water-based solution. Solid benzocaine is a white powder that has limited solubility in water. It much more easily dissolves, in order of greatest solubility to least, in chloroform, ether and alcohol; it is also soluble in dilute acids.
