Chloroxylenol, also known as para-chloro-meta-xylenol (PCMX), is an antiseptic and disinfectant agent used for skin disinfection and cleaning surgical instruments. It is also commonly used in antibacterial soaps, wound-cleansing applications and household antiseptics. The halophenol is shown to be most effective against Gram positive bacteria where it disrupts the cell wall due to its phenolic nature . Chloroxylenol is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system.

The predominant medical applications for which chloroxylenol is formally indicated for therapeutic use is as an application to the skin for use in cuts, bites, stings, abrasions, and for use as antiseptic hand cleaner .
Chloroxylenol is a substituted phenol which has been widely used for many years as an ingredient of antiseptic and disinfectant products intended for external use . It is known to be bactericidal in low concentration to a wide range of Gram positive and Gram negative bacteria .
- Mechanism of action
As a phenol antiseptic, it is believed that the hydroxyl -OH groups of the chloroxylenol molecule binds to certain proteins on the cell membrane of bacteria, and disrupts the membrane so as to allow the contents of the bacterial cell to leak out . This allows chloroxylenol to enter the bacterial cell to bind further with more proteins and enzymes to disable the cell's functioning . At particularly high concentrations of chloroxylenol, the protein and nucleic acid content of targeted bacterial cells become coagulated and cease to function, leading to rapid cell death .
No chloroxylenol was detected in the blood following the dermal administration of 2 g of p-chloroxylenol in an ethanol/olive oil vehicle in human subjects . After a dose of 5 g, only traces were found, after 8 g, 1 mg % (1 mg/dL) was found in the blood after 3 hours, and 4 mg % (4 mg/dL) after 24 hours . After a dose of 20 g, 4 mg % (4 mg/dL) was measured after half an hour, and 1 mg % (1 mg/dL) was present at 72 hours .
For antiseptic purposes, chloroxylenol is considered to be well-absorbed when applied to the skin .
- Volume of distribution
The only data available regarding the volume of distribution of chloroxylenol is the mean Vss of 22.45 L determined after 200 mg intravenous single dose of chloroxylenol was administered to healthy mongrel dog subjects [6, 8].
- Protein binding
One study determined the protein binding of chloroxylenol to be approximately 85.2% +/- 2.32% for serum albumin and 89.8% +/- 2.99% for whole human serum .
Certain animal studies have shown that following dermal application of chloroxylenol, that the absorption was rapid with a Cmax = 1-2 hours, and that the administered substance was excreted via the kidney with almost complete elimination within 24 hours . The primary metabolites discovered in the excreted urine were glucuronides and sulfates . Some chloroxylenol monographs liken its pharmacokinetic profile to that of another antiseptic - triclosan - which is rapidly excreted in the urine also as a glucuronide metabolite, as observed in the human model .
Moreover, In one human subject administered 5 mg intragluteally, 14% was excreted with glucuronic acid and 17% with sulfuric acid at 3 days .
Any chloroxylenol absorbed into the body is likely extensively metabolized by the liver and rapidly excreted, mainly in the urine, as sulphate and glucuronide conjugates .
- Route of elimination
- Half life
One study estimated the mean terminal half-life and mean residence time after a 200 mg intravenous single dose of chloroxylenol in healthy mongrel dog subjects to be 1.7 and 1.69 hours, respectively [6, 8]. Alternatively, some product monographs liken chloroxylenol to a similar liquid antiseptic, triclosan, whose calculated urinary excretion half-life in man is approximately 10 hours .
The only data available regarding the clearance of chloroxylenol is the mean clearance rate of 13.76 L/hr following a 200 mg intravenous single dose of the substance into healthy mongrel dog subjects [6, 8].
Moreover, in another study, when 8 g of chloroxylenol was administered dermal on a human subject in an alcohol/glycerin vehicle, 11% was excreted in 48 hours .
As chloroxylenol is predominantly employed as an active ingredient in various liquids or creams as cleaners, disinfectants, or antiseptics that are generally designed to be used topically, it is widely accepted that the use of such liquids - when used appropriately - is unlikely to present a sufficient volume that could be ingested to cause any medical problems . In the event of accidental eye contact, was with Luke warm water .
Chloroxylenol is known to have a low systemic toxicity, even at dosage levels many times higher that those likely to be absorbed during normal usage of the agent .
