Benzene Is Classified as a Human Carcinogen

Benzene is classified as a known carcinogen, according the American Cancer Society. Substances that may cause cancer are classified as known, probable, and possible carcinogens. The chemical can occur naturally in the environment and is found in crude oil and gasoline. Benzene is also used to make some types of lubricants, detergents, dyes, and pesticides, according to the Centers for Disease Control and Prevention (CDC). Benzene exposure can occur via inhalation, orally, and through the skin. Most people are exposed to it by breathing air that contains the chemical. Workers in industries that produce or use benzene may be exposed at the highest level, but mainstream cigarette smoke is another source, and accounts for about half the total U.S. population exposure to the chemical.

Recalled Products Not Expected to Cause Health Issues

The chemical is hazardous because it can cause cells to malfunction. For example, it can cause bone marrow not to make enough red blood cells, which can lead to anemia. Benzene exposure can result in cancers including leukemia, blood cancer of the bone marrow, and potentially life-threatening blood disorders. The risk posed by benzene depends on the amount, route, and length of time a person was exposed, as well as the age and any preexisting medical conditions of the exposed person. Based on an independent health hazard evaluation, daily exposure to benzene in the recalled dry shampoos would not be expected to cause adverse health consequences, per the FDA’s statement. Unilever U.S. is recalling the products “out of an abundance of caution.” An internal investigation identified the propellant as the source of the benzene, and the company has worked with its propellant suppliers to address the issue, according to the company’s statement. When a user presses the valve on top of a can or bottle, the propellant forces the product contained within through an internal tube and out of the valve, creating a spray or foam.
