LEXETTE is a hydroethanolic aerosol foam that contains a corticosteroid, halobetasol propionate intended for topical use. The chemical name of halobetasol propionate is 21-chloro-6α, 9-difluoro-11β, 17-dihydroxy-16β-methylpregna-1, 4-diene-3,20-dione 17-propionate.

It is practically insoluble in water and freely soluble in dichloromethane and in acetone. Each gram of LEXETTE contains 0.5 mg of halobetasol propionate in a white to off-white foam base consisting of alcohol (specially denatured alcohol [SDA]), benzoic acid, cetostearyl alcohol, emulsifying wax, polyoxyl 20 cetostearyl ether, propylene glycol and purified water. LEXETTE is dispensed from an aluminum can pressurized with a hydrocarbon (isobutane and propane) propellant.
