Patent Pick: Topical Cranberry Tackles Intimate Cleansing, Microflora Balance


As is well-known, the body's microbiome extends beyond the gut, and this delicate balance can easily be disrupted by antibiotics or even alcohol-based cleansers. The inventors on a patent application therefore sought to provide an alternative, alcohol-free composition that is not based on Lactobacillae for topical use in the prevention and treatment of skin and mucosal infections, especially of male and female sexual organs.

According to the invention, the desired composition would be capable of restoring and stabilizing the vaginal flora's natural acidity between pH 3.0 and 4.5 over a prolonged period of time, minimally for 3 hr. Furthermore, it would be generally regarded as safe (GRAS) and its major components must be food-grade to allow for potential applications as a lubricant. Finally, it must be fully latex condom-compatible/safe and may have a lubrifying effect.
