Dettol is a British brand of antiseptic cleaning products made by the brand RB (formerly Reckitt Benckiser).

Dettol is not widely available in the U.S., but you can purchase some of the brand's products on sites such as Amazon.


The key active ingredient in Dettol is a modified form of the antiseptic phenol, called chloroxylenol BP, according to the Royal Society of Chemistry (RSC). Dettol contains chloroxylenol BP in a 4.8 percent concentration of weight to volume, according to the UK Electronic Medicines Compendium.

Ingredients in Dettol Antiseptic

  • Active ingredient:​ Chloroxylenol BP (antiseptic, disinfectant)
  • Isopropyl alcohol (antiseptic)
  • Pine oil
  • Castor oil soap
  • Caramel coloring
  • Water

1. Chloroxylenol Kills Bacteria and Some Viruses

Chloroxylenol is the active antibacterial ingredient in Dettol that kills bacteria, mycobacterium, fungi and some viruses, according to an FDA report prepared for the American Cleaning Institute in 2014.

Dettol has been confirmed to kill strains of the coronavirus, but according to the company, it has not yet been possible to test the products' effectiveness against the virus that causes COVID-19. However, the National Environment Agency of Singapore lists several Dettol products on its roster of household products that contain the appropriate concentration of active ingredients to disinfect areas likely to be contaminated with the novel coronavirus. These products include:


  • Dettol Anti-bacterial Surface Cleanser Trigger Spray
  • Dettol Antiseptic Disinfectant Liquid
  • Dettol Antiseptic Germicide
  • Dettol Healthy Clean Bathroom
  • Dettol Healthy Clean Kitchen

According to the National Center for Biotechnology Information (NCBI), chloroxylenol, as well as other disinfectants, can cause mild skin irritation in some individuals or cause an allergic reaction in others.


Seek immediate medical attention if any of these signs occur while using Dettol:

  • A rash or hives with swelling of the face, mouth, throat or tongue
  • Tightness of the chest and difficulty breathing
  • Redness, burning, blisters or peeling of the skin

2. Isopropyl Alcohol Has Antiseptic Properties

Isopropyl is a secondary antiseptic ingredient. This is a strong-smelling, colorless, flammable chemical compound that gives Dettol the ability to kill bacteria and and viruses, according to the Centers for Disease Control and Prevention (CDC).



Isopropyl alcohol is often used to disinfect medical tools like stethoscopes, but it is not used for sterilization because it does not kill fungal spores. This is why Dettol includes both chloroxylon ​and​ isopropyl alcohol: to kill bacteria, fungi and viruses.

3. Pine Oil Is a Mild Antiseptic

Pine oil is made from the cone, twigs and needles of the pine tree. When pine oil is diluted in water it emulsifies, or forms a cloudy liquid. This cloudiness also occurs when Dettol is diluted.


Pine oil has mild antiseptic and disinfectant properties and a distinct aroma that characterizes Dettol and other products made with pine oil, according to Science Direct. Pine oil is also used in a variety of bath oils and bath soaps and as an essential oil in aromatherapy.

4. Castor Oil Soap and Other Ingredients

Castor oil soap is a product made from castor bean oil. The soap contains a high concentration of ricinoleic acid, the active ingredient in castor oil. The ricinoleic acid is essential for holding the other active ingredients in Dettol in cohesive solution until it is diluted with water for use, per the RSC.


Caramel coloring and water are the other ingredients in Dettol. Caramel gives Dettol its yellowish-brown color and the water acts as a diluent, binding the other ingredients together.


Do not ingest Dettol. These products are made for exterior use only. Always follow the instructions and warning labels provided on the product's packaging.
