General Description
Phenols (petroleum) are a group of chemical compounds derived from petroleum that contain a hydroxyl group attached to an aromatic benzene ring. These compounds are commonly found in petroleum products and are known for their strong disinfectant properties, making them useful in the production of cleaners, disinfectants, and antiseptics. However, phenols can also be harmful and toxic to humans and the environment if not handled properly. Exposure to phenols can cause irritation to the skin, eyes, and respiratory system, as well as more serious health effects such as organ damage and cancer. Due to their potential risks, it is important to use phenols safely and follow proper handling and disposal protocols when working with these chemicals.
