Just last week (28 April 2022), Australia’s Therapeutic Drugs Administration (TGA) issued an urgent recall for six popular brands of sunscreen due to concerns over unacceptable levels of a known cancer-causing compound found in these products.
The agency has warned that more products may be added to the list in coming weeks as their investigations continue into how the contamination happened.
The known carcinogen, benzene, was found in a batch of raw material used in the manufacture of a number of sunscreen products including:
The TGA advises that anyone who has purchased these products (with the affected batch numbers) should immediately return the product to the place of purchase and contact the manufacturer. Contact details for each manufacturer are available on the TGA website.
What is Benzene?
Benzene is an elementary petrochemical derived from crude oil. It is primarily used in the manufacture of other chemicals. Benzene is recognised as a carcinogen that, with prolonged exposure, increases the risk of certain cancers, bone marrow failure and a range of other illnesses including leukaemia and cardiovascular disease.
In 1948 the American Petroleum Institute (API) stated,”….it is generally considered that the only absolutely safe concentration for benzene is zero.”
Modern humans are regularly exposed to benzene through gasoline and hydrocarbon fuels, and very low levels of exposure for short periods of time is considered a comparatively low health risk.
In Australia benzene levels must be below 2 parts per million (ppm) in all sunscreen products.
Addressing the recall, the TGA says, “Although exposure at the levels detected would not be expected to cause serious adverse health effects, and risks to users are considered low, the sunscreens are being recalled to ensure consumer safety.”
How did Benzene Get Into Sunscreen?
Benzene is not an ingredient that is normally added to sunscreen and so the TGA has launched an investigation into the contamination. It’s believed that a raw ingredient batch used in all the sunscreens on the list above, was inadvertently contaminated with benzene during the manufacturing process.
According to the TGA website: “It (benzene) has been detected in one batch of a raw material used in the manufacture of a number of products and the TGA is working with affected companies to confirm if benzene is present in their medicines and if it is, how much is there.”
