Which of the following is phenol primarily used for?

Phenol is primarily used as a disinfectant and antiseptic agent, especially effective in sanitizing metallic implements. Its chemical properties make it potent against a range of pathogens, allowing it to effectively reduce the risk of infection when applied to non-porous surfaces like metal tools utilized in beauty and personal care treatments. This is particularly important in settings where hygiene and sanitation are paramount, such as in lash extension practices.

While phenol may have other uses in different contexts, its primary role in the beauty industry is related to sanitization and disinfection. Understanding this application is crucial for maintaining proper hygiene standards in any practice involving skin contact or potential exposure to biological materials. Therefore, its use as a sanitizer for metallic implements aligns with best practices in professional beauty services.
