Which chemical agents are safe to use on the skin?

Antiseptics are chemical agents specifically formulated to be safe for use on the skin. They are designed to prevent the growth of microorganisms and are commonly used to disinfect the skin and minor wounds. Antiseptics can include ingredients such as alcohol, chlorhexidine, and iodine, which are effective at killing bacteria and preventing infections without causing significant harm to skin tissues.

In contrast, acids, solvents, and alkaline cleaners can be harmful or irritating to the skin. Acids can lead to chemical burns or irritation, especially if not formulated for skin use. Solvents, which are often used for cleaning or dissolving substances, can dry out or damage skin. Alkaline cleaners, similarly, can disrupt the skin's natural pH and lead to irritation or damage over time. Therefore, while these agents may have particular uses in other contexts, they are not considered safe for direct application on the skin, making antiseptics the preferred choice for skin sanitation.
