Formulations/Preparations:
•grades: usp; technical •available as an ointment, cream, or lotion in concentrations of 1 to 10%. it is also used as compound resorcinol ointment, which contains 6% resorcinol. resorcinol monoacetate gradually liberates resorcinol and, therefore, exerts a milder but more lasting action. it is used for the same purposes as resorcinol. resorcinol monoacetate is compounded with sulfur in preparations for seborrhea. •castellani paint topical antifungal agent contains resorcinol, basic fuchsin, phenol, acetone and alcohol •night cast formula r medicated acne mask contains 2% resorcinol, 8% sulfur and 31% alcohol •resinol ointment and resinol greaseless cream contain 2.0% resorcinol •resulfolin contains 3% resorcinol monoacetate
