Ethanol disinfectant is commonly known as alcohol disinfectant. Because of its strong stimulating effect, ethanol disinfectant should not be used directly on wounds, especially on the wound surface and mucous membranes. Ethanol disinfectant not only irritates the patient and makes it very painful, but also stimulates the local cells and does not easily heal the wound. For disinfection of wounds and mucous membranes, iodophor can be used because it does not contain irritating ingredients such as ethanol, which is a disinfectant made by mixing iodine with water.
