Abstract: The invention relates to an unexpected discovery that propylene glycol is highly effective at killing or inhibiting Propionibacterium acnes in a mammalian skin disorder, as well as to the use of propylene glycol and salicylic acid in a skin-disorder treatment. This invention also relates to compositions containing propylene glycol alone or in combination with salicylic acid for use in killing or inhibiting Propionibacterium acnes.

Abstract: Disclosed herein is a composition containing a high concentration of PG is unexpectedly capable of quickly killing other bacteria, fungi, and/or virus in vitro that is indicative of its potential high efficacy in treating various skin infection. Embodiments disclosed herein relate to a composition and method for effective topical treatment of inflammatory skin lesions in mammals, comprising of a high concentration of propylene glycol alone, or in combination with an astringent. The PG at high concentrations can be regarded as an extremely effective, safe, topical, universal, microbicide.
