Sure deodorant is generally safe for everyday use, but the brand does have a notable safety history worth knowing about. In 2022, several Sure aerosol products were recalled nationwide due to benzene contamination, and the product contains ingredients that raise common questions about long-term safety. Here’s what the evidence actually shows.
The 2022 Benzene Recall
In February 2022, HRB Brands (the company behind Sure) issued a voluntary nationwide recall of Sure aerosol sprays after testing found unexpected levels of benzene, a known carcinogen. The recall covered two products: Sure Regular Antiperspirant Aerosol (6 oz) and Sure Unscented Antiperspirant Aerosol (6 oz), across all lot numbers with expiration dates on or before August 2023.
Benzene wasn’t an intentional ingredient. The contamination came from the propellant used to spray the product out of the can. If you still have a can of Sure aerosol from that era, check the expiration date. Any can expiring before August 2023 should have been discarded. Products manufactured after the recall period are not affected.
What’s Actually in Sure Deodorant
Sure’s antiperspirant formula uses aluminum chlorohydrate at 10% as its active ingredient. This is the compound that temporarily blocks sweat glands to reduce perspiration. The inactive ingredients include cyclopentasiloxane and dimethicone (silicones that help the product glide on smoothly), isopropyl myristate (a skin-conditioning agent), and fragrance. Notably, the formula does not contain parabens or phthalates, two categories of chemicals that often concern consumers.
The aerosol versions use butane and hydrofluorocarbon 152a as propellants to push the product out of the can. These are standard aerosol propellants found across the personal care industry.
Aluminum and Health Concerns
Aluminum in antiperspirants is probably the most searched safety question in this entire product category. Two concerns come up repeatedly: a possible link to breast cancer and a possible link to Alzheimer’s disease. Decades of research have not established a causal connection for either one. Major health organizations, including the American Cancer Society, do not list antiperspirant use as a known risk factor for breast cancer.
The European Commission’s Scientific Committee on Consumer Safety (SCCS) reviewed aluminum in cosmetics extensively and published its findings in 2023. The committee concluded that aluminum compounds are safe in non-spray products at established maximum levels. For spray products like Sure’s aerosol, the committee added a condition: the percentage of very fine particles (smaller than 10 micrometers) should not exceed 20% of total sprayed particles, since those tiny particles can potentially be inhaled deep into the lungs. This is worth noting if you use the aerosol version, as it means proper use matters. Spray in a ventilated space and avoid inhaling directly.
Sure’s 10% aluminum chlorohydrate concentration falls within typical ranges for consumer antiperspirants and is well below prescription-strength formulas.
Aerosol Propellant Risks
The butane propellant in Sure’s aerosol cans is safe under normal use conditions, but it does carry real risks if misused. Inhaling butane or isobutane directly can irritate the nose and throat, causing coughing and wheezing. At high concentrations, exposure can cause dizziness, irregular heartbeat, disorientation, and loss of consciousness. At very high levels, it displaces oxygen and can be fatal. These risks apply to intentional inhalation (huffing), not to spraying deodorant on your underarms in a bathroom.
That said, using aerosol deodorants in small, unventilated spaces like a tiny bathroom with the door closed does increase your exposure to propellant fumes. Cracking a window or leaving the door open is a simple way to minimize this. If you’re sensitive to aerosol sprays or have asthma, a stick or roll-on version avoids the propellant issue entirely.
Fragrance and Skin Reactions
Sure lists “fragrance” as a single ingredient, which is standard practice in the U.S. but means the specific fragrance chemicals aren’t disclosed on the label. This matters because fragrance is one of the most common causes of contact dermatitis in cosmetic products. The European Union has identified 26 fragrance compounds as known allergens, including citronellol, limonene, and linalool, all of which are extremely common in scented personal care products.
If you’ve experienced redness, itching, or a rash from Sure or similar deodorants, fragrance is a likely culprit. Sure does offer an unscented version, which may reduce (though not necessarily eliminate) the risk of fragrance-related reactions, since even “unscented” products sometimes contain masking fragrances.
Aerosol vs. Stick Formats
Your choice of format changes the safety profile slightly. The aerosol version introduces two variables that the stick does not: propellant inhalation and the potential for inhaling fine aluminum particles. Neither is a serious concern with normal use in a ventilated room, but both are worth considering if you have respiratory sensitivities or use the product multiple times a day. The stick format delivers the same active ingredient directly to skin without any inhalation component, making it the simpler choice from a safety standpoint.
For most people, Sure deodorant in any format poses no meaningful health risk when used as directed. The benzene recall was a manufacturing issue that has been addressed, the aluminum concentration is within established safety limits, and the formula is free of parabens and phthalates. The main practical concern is fragrance sensitivity, which you can test by trying the product on a small patch of skin before committing to daily use.
