Q: Can phenol be used as a household cleaner or disinfectant?

A: Phenol is not commonly used as a household cleaner or disinfectant due to its toxicity and potential health risks. There are safer and more effective alternatives available for household cleaning purposes.

Q: Is phenol still used as a general anesthetic?

A: Phenol was historically used as a general anesthetic, but it has been largely replaced by safer and more advanced anesthetic agents in modern medical practice.

Q: Is phenol harmful to the environment?

A: Phenol can be harmful to the environment if not properly managed. It is toxic to aquatic life and can have negative impacts on ecosystems if released into water bodies. Proper disposal and adherence to environmental regulations are necessary to minimize its environmental impact.

Q: Can phenol be used for wood preservation?

A: Yes, phenol can be used for wood preservation. It has been employed as an effective wood preservative to protect against decay and insect infestation. However, it is important to follow proper application guidelines and safety precautions when using phenol-treated wood.

Q: Is phenol used in the production of cosmetics?

A: While phenol itself is not commonly used in cosmetics due to its potential irritant properties, derivatives of phenol, such as phenolic compounds, may be utilized as preservatives or antioxidant agents in some cosmetic formulations. Cosmetic products undergo strict safety assessments to ensure consumer safety.
