Yes, Dettol is slightly acidic.
While Dettol contains multiple ingredients, the soap component is made from castor oil, which contains ricinoleic acid. Ricinoleic acid is a fatty acid with the systematic name 12-hydroxy-(cis)-9-octadecenoic acid. Acids are substances that have a pH lower than 7, and ricinoleic acid contributes to the acidic nature of the solution.
Understanding Acidity in Dettol
Although Dettol may contain other compounds that could affect its overall pH, the presence of ricinoleic acid derived from castor oil is a key reason for its slight acidity.
Here's a breakdown:
-
Ricinoleic Acid: This fatty acid found in castor oil is an organic acid. Acids, by definition, release hydrogen ions (H⁺) in a solution, making the solution acidic.
-
Dettol's overall pH: Due to the presence of acidic compounds such as ricinoleic acid, Dettol typically has a pH value below 7, making it acidic. The exact pH can vary slightly between formulations.

Practical Insights:
- Acidity is crucial for the function of many disinfectants, including Dettol, as it helps to disrupt the cell membranes of bacteria and viruses, aiding in their destruction.
- The mild acidity of Dettol is not usually harmful for general topical use, however always follow usage instructions, and always dilute Dettol before use.
Components of Dettol and their impact on Acidity:
| Component | Description | Impact on Acidity |
|---|---|---|
| Ricinoleic Acid | Fatty acid derived from castor oil. | Acidic |
| Chloroxylenol | The primary disinfectant component of Dettol. | Slightly Acidic |
| Other ingredients | Includes isopropyl alcohol, pine oil and water. | Varies |
Therefore, considering the presence of ricinoleic acid, derived from castor oil used in the soap component, Dettol can be classified as slightly acidic.
