Potassium hydroxide is a key ingredient in cuticle remover formulations due to its role as a strong alkaline compound. It works by breaking down the bonds between the dead skin (the cuticle) and the nail plate, making it easier to gently push back or remove the cuticles during a manicure or pedicure. This effective dissolving action allows for a cleaner and more precise nail care process, enhancing the overall appearance of the nails.

Other choices, such as mineral oil, lanolin oils, and bismuth oxychloride, serve different purposes in nail care products. While mineral oil and lanolin are often included for their moisturizing properties, and bismuth oxychloride might be found in cosmetic formulations for additional shine or color, they do not possess the same cuticle-dissolving ability as potassium hydroxide. This distinguishes potassium hydroxide as the most effective component for cuticle removal in nail care.
