What type of disinfectants has a high pH and can cause skin irritation or burns?

Phenolic disinfectants are known to have a high pH, which can lead to irritation and potentially cause burns if they come into contact with the skin. These disinfectants are derived from phenol and are effective in killing a wide range of pathogens, making them popular in various settings, including salons and spas. However, due to their potency and high pH level, they must be used with caution, ensuring proper dilution and protecting the skin during application.

The other disinfectants listed have different properties and pH levels. Alcohol-based disinfectants are typically lower in pH and generally do not cause burns but may cause dryness. Quaternary ammonium compounds are often less irritating and are used for their mildness; they maintain a neutral pH. Chlorine-based disinfectants can also cause irritation due to their chemical composition, but their primary concern is often related to the fumes they produce rather than direct skin burns from contact.
