Benzene in Aerosol Sprays: What the Recalls Actually Found

The short answer

Two separate recalls, a year apart, found benzene in aerosol personal-care products: Johnson & Johnson's Neutrogena and Aveeno aerosol sunscreens in July 2021, and Unilever's Dove, Nexxus, Suave, TIGI, and TRESemmé aerosol dry shampoos in October 2022. In both cases, the companies traced the source to the propellant — the pressurized gas that pushes the product out of the can — not to any ingredient deliberately added to the formula. Both recalls covered specific, identified lots, and both were voluntary.

That's a real, documented finding. It is not the same statement as "aerosol sprays contain benzene" or "aerosol dry shampoo is contaminated." The recalls were lot-specific and propellant-specific, and neither company nor the FDA found benzene in every aerosol product on the market, or even in every lot of the recalled product lines.

Where the concern came from

Benzene is a well-established human carcinogen, and it isn't supposed to be part of any cosmetic or over-the-counter drug formula. It showed up in these products as a manufacturing contaminant rather than an ingredient — the FDA's own guidance on the issue notes that benzene contamination in recalled aerosol drug products has been linked to things like isobutane propellant and other hydrocarbon-based components, not to anything the brands intended to include.

The pattern started with a citizen petition filed with the FDA by an independent testing lab, which prompted the agency and manufacturers to test aerosol sunscreens, antiperspirants, and other sprays more closely. That testing is what turned up the specific lots later recalled by Johnson & Johnson and Unilever. It's worth being precise about what triggered each recall, because "testing found it" is a different claim than "it's known to be present."

What the evidence actually shows

Both recalls are on the record with the FDA, and both companies published what their own investigations found:

• Neutrogena/Aveeno aerosol sunscreen (July 2021): Johnson & Johnson recalled all lots of five product lines — Neutrogena Beach Defense, Cool Dry Sport, Invisible Daily Defense, and Ultra Sheer aerosol sunscreens, plus Aveeno Protect + Refresh aerosol sunscreen — after internal testing found low levels of benzene in some samples. The company stated benzene is not an ingredient in any of its sunscreen products, and that the recall was issued out of caution while the cause was investigated.

• Dry shampoo aerosols (October 2022): Unilever recalled select lot codes of Dove, Nexxus, Suave, TIGI (Rockaholic and Bed Head), and TRESemmé dry shampoo aerosols produced before October 2021, after an internal investigation identified the propellant as the source and the company began working with its propellant suppliers to fix it.

On health risk, the FDA's position — stated in both the general benzene guidance and the individual recall notices — is that daily exposure to benzene at the levels actually detected in the recalled products "would not be expected to cause adverse health consequences," and that both companies issued their recalls out of an abundance of caution rather than because of a confirmed injury pattern. The FDA has continued to recommend people keep using sunscreen, calling it an important part of skin-cancer prevention that outweighs the low benzene exposure risk from the small number of affected lots.

Separately from the benzene question, aerosol products in general are subject to federal hazardous- substance labeling rules. Aerosols that meet the legal definition of a hazardous substance — flammable, pressurized, an irritant, and so on — are required to carry precautionary label language, including directions like using the product in a ventilated area and a "keep out of reach of children" statement or its equivalent. That's a standing regulatory requirement that predates and is unrelated to the benzene recalls; it applies to aerosol cans generally because of how they're pressurized and formulated, not because of any finding specific to young children and this particular contaminant.

What SafeMama actually recommends

This isn't a page that ends in "throw out your aerosols." The recalled lots are years old and were pulled from shelves; there's no ongoing finding that current aerosol dry shampoo or sunscreen on store shelves is contaminated. Generalizing a lot-specific manufacturing issue into "don't use aerosols" would overstate what these two recalls actually showed.

What's reasonable to take from this: if you're using an aerosol personal-care product, follow the label — use it in a ventilated space, don't spray it directly at your own or a child's face, and store it the way hazardous-substance labeling already requires, out of reach of young children. None of that is new advice specific to benzene; it's the same handling guidance that applies to pressurized aerosols generally.

If you'd rather sidestep the open question about aerosol propellants altogether, dry shampoo and sunscreen both come in pump, stick, and lotion formats with no propellant involved. That's a preference, not a correction — the evidence here doesn't establish today's aerosol products as unsafe.

The exposure quiz scores how often your household reaches for aerosol personal-care sprays — a frequency signal for your own reference, not a claim about risk. A "worth a look" result here means your answers landed on the higher-frequency end of this specific question, nothing more.
