In general, antiseptics are used only on the skin and not for surface disinfection, and disinfectants are not used for skin antisepsis because they can injure skin and other tissues.
How are chemical germicides categorized?
Chemical germicides can be classified into two major categories: those that are formulated as disinfectants and those formulated as anti- septics, preservatives, or drugs to be used on or in the human body or as preparations to be used to inhibit or kill microorganisms on the skin.

Key Concepts and Summary. Chemical disinfectants are grouped by the types of microbes and infectious agents they are effective against. High-level germicides kill vegetative cells, fungi, viruses, and endospores, and can ultimately lead to sterilization.
