Owing to its toxicity, phenol itself is used only as a disinfectant of inanimate objects. Mixtures of phenolic derivatives are used in antiseptics but can cause skin irritation. Antiseptic soaps may also contain other chlorinated phenols such as triclocarban and chlorhexidine. Chlorhexidine is mainly active against grampositive cocci and is commonly used in hospital scrub routines to cleanse skin sites. All antiseptic soaps may cause allergies or photosensitization.
