Their primary function in cosmetics is to serve as preservatives thanks to their antimicrobial properties. In addition to this function, decyloxazolidinone is also an effective skin conditioning ingredient. That’s because it’s designed to mimic ceramides in skin’s surface layers, technically known as the stratum corneum. It is considered non-irritating in concentrations as high as 10%, far above its usual usage in cosmetics products. It is also used as a penetration enhancer. In its raw form, decyloxazolidinone is a white, crystalline, odorless solid. It is also commonly referred to by its trade name, DERMAC SR-38. Related ingredients: Surfactant
