What Is Cresol?
Cresol, a methylphenol compound with the molecular formula C7H8O, is a colorless or yellowish liquid with a characteristic odor. It exists in three isomers: ortho, meta, and para. Derived from coal and wood tar, it’s insoluble in water but soluble in ethanol and diethyl ether.
Uses of Cresol
As a disinfectant and solvent, Cresol is utilized in various industries, including the production of fragrances, dyes, insecticides, synthetic resins, lubricating oils, and explosives. It’s also employed in the medical field as a disinfectant in various forms.
Medical Applications
Used for skin disinfection and sterilizing medical equipment, Cresol’s effectiveness varies with concentration. It’s used in lower concentrations for sensitive areas and must be handled carefully to avoid skin absorption and potential toxicity.
Sterilizing Effects
Cresol’s sterilizing power is stronger than phenol but weaker against spores and most viruses. Commercially available Cresol soap, once a common disinfectant, is now used mainly in specific scenarios like flood aftermaths and livestock epidemics.
Storage Recommendations
Cresol should be stored at room temperature in airtight, light-shielded containers. Over time, it may darken or slightly alter in appearance depending on the container material. Care is needed to prevent odor migration.
