Which disinfectants have a high pH and can cause skin irritation or burns to the skin or eyes?

Alcohol disinfectants
Bleach disinfectants
Phenolic disinfectants
Quaternary ammonium compounds

The correct answer is: Alcohol disinfectants

The correct choice identifies disinfectants that have a high pH and can lead to skin irritation or burns. Specifically, bleach disinfectants, which can contain sodium hypochlorite, have a high pH level typically around 11 to 13. This elevated pH contributes to their potential for causing chemical burns and irritation to the skin and eyes. While alcohol disinfectants, such as isopropyl alcohol, are effective for sanitization, they generally have a lower pH and are less likely to cause severe irritation or burns compared to bleach. Understanding the properties of disinfectants is crucial for safe application in cosmetology settings, as it ensures the protection of clients and professionals from harmful reactions.
